3 groups on the standard car battery

In Electric Vehicle Conference "EVS24" (2009, 13 May to 16 May, Norway StavangarForum), the number of organizations have to plug-in hybrids (PHEV) with the charging system, as well as lithium-ion rechargeable battery standard published a speech. PHEV, the International Electrotechnical Standards Committee (IEC), International Organization for Standardization (ISO) and the American Association of Automotive Engineers (SocietyofAutomotiveEngineers, SAE) were introduced by their respective standardization efforts, these standardized specifications for the connection and charging PHEV facilities, communication technology and systems. Standardization activities of these groups, respectively, by the German companies (ISO), French companies (IEC) and the American Enterprise (SAE)-led implementation.

Standardization of PHEV

IEC and ISO for the realization of PHEV charging facilities connected with the standardization activities carried out, is aimed at harmonizing the views of the two groups "IEC/ISOJWGV2G jointworkinggroupvehicletogrid)" organized and implemented. Germany's leading energy companies RWEAG the IngoDiefenbach progress of the work of the organization delivered a speech.

IEC/ISOJWGV2G has two working groups (WG). One is related with the physical specifications of WG1. Specific work includes, discussion connectors, cables, both protection and power switching and base. In the more contentious aspects of the connector, IEC envisages only be used to connect charging devices and cars, and made the biggest three-phase AC voltage of 500V, maximum current and seven terminals 63A (3 for the power supply, one for the Grounding, 2 for the signals, one for other uses) and so on.

The other is related with the communication technology WG2. The discussions included a more secure method of communication and communication services. Focused on the content, in the circumstances at the same time clearly identified for its specifications, and to ensure connectivity between the communication protocol. IEC/ISOJWGV2G 09 years in the aggregate result of these issues and to develop programs intended to vote in mid-2010, the end of 2010 to develop standards. Although the IEC and ISO views seem more unified, but in fact the current "still have considerable differences" (IngoDiefenbach).

On the other hand, research institutions, the U.S. Argonne National Laboratory (ArgonneNationalLaboratory) of TheodoreBohn progress on the standardization of SAE delivered a speech. PHEV standardization, SAE group generally consists of two specifications. PHEV are used to connect the specifications and infrastructure group, and the development of PHEV and EV for the test method specification group. Vehicles and infrastructure to achieve the connection "V2G", including connectors, charging method, communication protocols, such as use cases and charging device specifications. Example contains the relevant provisions of the connector "J1772", including the largest one-way 115V AC voltage, maximum current of 15A and 5 terminals (2 for the single-phase AC use, one for the grounding, one for the signals, one for the other purposes). This IEC/ISOJWGV2G differ materially from those discussed in, "I hope the two sides compromise" (TheodoreBohn). Will be discussed in future to improve the three-phase AC voltage to 600V and 600A current and so on.

In addition, SAE is also envisaged through the wire communication (PLC) device is connected vehicles and charging facilities, and to consider future vehicle information uploaded to the Web network. "Because the next vehicle and the linkage between the intelligent instrument will become very important" (TheodoreBohn).

Standardization of vehicle batteries

On the standardization of the battery, Belgium ErasmusUniversityCollegeBrussels the Petervandenbossche progress on the current delivered a speech. At present, the standardization of automotive batteries, including lead-acid battery standards IEC60254, and the overall battery standards IEC61982. The latter also includes the electric power per km for the standard car battery 100Wh the IEC61982-3.

Based on these criteria, the group has started discussing 08 hybrid lithium-ion rechargeable battery standards. Lithium-ion rechargeable batteries, ISOTC22SC21 being developed with the vehicle's rechargeable battery system, standards, and IECTC21 are being rechargeable battery units and modules to focus on the development of relevant standards. Plan "will continue with the IEC, ISO and other groups to discuss again" (Petervandenbossche). In addition, also intend to discuss the future of lithium-ion capacitor standards.

MI Yu Kai Investment earnings

On Friday, petrochemical and banking stocks such as planes weight plates stabilized stabilized, making A shares rebound after opening. News of the power sector in the overall trend of strong stimulation to promote the broader market volatility higher, but the relative lack of trading volume led to more limited efforts in the broader market upward.

It is noteworthy that, after trading sharply higher lithium whole concept of plate, CITIC Guoan, Tibet Mining, Shanshangufen, Jiangsu Guotai and other species only limit or close to the limit, and promote the variety of subjects related to battery power far, Desai battery Joining such strength. Beginning of this year, up and down in the A-share market as a whole dilemma of the occasion, as the very imagination of the plate, the concept of a strong rise of lithium compelling.

New energy trying to save the "American soldier"

In the eyes of hundreds of millions of American people expect, the Democratic candidate Barack Obama has finally been elected the 56th President of the United States. Hundred years of financial crisis facing the face of the deteriorating U.S. economy, how the young Obama and his economic team to develop a strong economic stimulus. The new government can lead the United States out of economic difficulties, the Obama campaign overall during the economic measures proposed strategy will lead the United States and the world economy, which in the current complex economic background, has become a global concern focus.

Although Obama and the new Congress took office in January 2009 will be held. But as a fundamental policy relating to the future --- U.S. energy policy, Obama has been placed in the new economic program in an extremely prominent position. In fact, a long time, America's main energy sources are non-renewable resources. Current U.S. petroleum energy consumption structure is 40%, 23% coal, natural gas 23%, while the proportion of new energy sources only 14%. Meanwhile, the U.S. automotive industry can be described as a double whammy, the three major car manufacturers near the edge of bankruptcy, or will result in hundreds of thousands of American blue-collar jobs. The spread of unemployment will be a further blow to the American consumer, the threat of millions of commercial and retail and service jobs.

In such a negative context, Obama plans to launch its new energy package: $ 150,000,000,000 into the next decade, funding alternative energy research, and related companies to provide tax incentives help to increase five million new jobs; the next decade, a substantial Middle East and Venezuela to reduce dependence on imported oil; to $ 7,000 tax credit limit to encourage consumers to buy fuel-efficient vehicles, the use of $ 4,000,000,000 in federal funds to support the auto makers, the target to 2015, U.S. sales of hybrid vehicles to reach 1 million; support mandatory "cap-and-trade" system, and strive to achieve by 2050 carbon dioxide emissions by 80%. Clearly, the Obama energy plan in the future the core focus, to focus on new energy vehicles.

Expected to become the starting point for the future prosperity of a new round of

Throughout the development process of the new U.S. economy is actually the constant creation and interpretation of the bubble process. From 1929, car, rail and air bubbles, the bubble in U.S. dollars in 1987 to 2000 Internet bubble, the enormous opportunities of technological progress and post-effective demand, driving the U.S. economy's long-term prosperity.

Face of the global financial crisis, upheaval, the future needs of the world economy to pick up even more breakthroughs in new technologies and production efficiency. To rely on the one hand, the economical use of energy for hybrid vehicles, systems design and battery research and development is the most important; the other hand, must rely on new energy technology breakthroughs. But no doubt that the future of new energy vehicles will certainly accelerate the development, and lithium battery power will become one of the biggest bright spot. It is noteworthy that, as the chairman of Berkshire Hathaway, Warren Buffett, the world's stock had God new energy power. September 2008, Warren Buffett's MidAmerican Energy announced a 232 million acquisition of approximately 225 million shares of BYD, the charm of new energy power is evident.

The development of new energy future of the automobile, but battery technology has become the key to development of the industry, the core technology in battery breakthrough has become the biggest bright spot. Among them, the lithium and lithium-ion batteries developed in the 20th century a new type of high-energy batteries. Because of its high energy, battery voltage, operating temperature range, the advantages of long storage life, has been widely used in military and civilian small appliances, such as mobile phones, portable computers, camcorders, digital cameras, and some instead of the traditional battery. With the continuous progress of science and technology, lithium-ion batteries for its unique performance advantages, has been started in electric vehicles, electric vehicles and will be the main driver of future power supply.

So, faced with market potential beyond the imagination, no doubt related to listed companies will face a major investment opportunities. Such as CITIC subsidiary of CITIC Guoan Guoan Li, is the largest lithium cobalt oxide cathode materials for lithium batteries and lithium manganese oxide manufacturers, but also the only large-scale domestic production of power lithium ion battery manufacturers, its power the battery is identified as the 2008 Beijing Olympic Beijing Olympics exclusive supply products, while other varieties include Cathay Pacific, Jiangsu, Tibet Mining, Shanshangufen and so on.

With the oversupply situation on global solar PV industry in 2009, the bubble may burst

In recent years, solar PV industry is growing rapidly attract large investors, policy makers and other eye. But the growing trend of the total may be a bubble will someday burst. The global solar PV industry continued rapid growth, from 21.2 billion U.S. dollars in 2007, forecast to 2012 will reach 70.9 billion U.S. dollars. By market research firm Lux Research's article entitled "Q1 2008 Global Solar Energy trends and birth crisis", the worldwide solar photovoltaic industry in the next two years may be turning.

As such as Japan, Germany, Spain and other countries for the implementation of solar photovoltaic industry of economic subsidies, making the global solar photovoltaic industry has developed rapidly in 2007 when the installed capacity had reached 3.43GW. During recent years because solar PV market demand continues to outstrip supply, leading to rapid increase in production capacity. But this situation will not last long, the market may be turning point in the day.

According to the forecast reported in 2009, when the global solar PV industry will be the situation of oversupply, causing prices to decline, some companies may be they can not quit, especially for those who do not invest in film-type solar cell monocrystalline silicon solar cell manufacturers may be more severe.

In order to clarify the global solar market, Lux Research analysis of the company 5 kinds of solar technologies; 1), single crystal silicon photovoltaic (PV), the current dominant; 2), the use of high concentrations of multi-junction PV (HCPV); 3) , inorganic thin film photovoltaic PV; 4), organic and Gratzel PV thin film PV; 5) solar thermal power generation technologies (solar thermal).

The team used a rigorous, pre-set method, for the five kinds of different technologies, three kinds of different applications and 10 countries, with separate models, for solar energy until 2012, when the forecast supply and demand. Eventually, the Panel Lux Research's database of global solar energy industry, including global investment in solar energy, each a commercial venture capital funds, each solar energy companies, IPO and merger activity per amount of solar energy companies, data from 1995.

Huanghua Airport issued a "refusal lithium order" suspension of lithium battery collection, transportation

Companies engaged in air cargo agency began to busy road and rail freight links with colleagues, because in the face of lithium transport, the Huanghua International Airport and the province's only base of China Southern Airlines Hunan branch usually say no. "Unless you have a professional safety certification authority of the United Kingdom," China Southern Airlines Cargo, a subsidiary of Hunan are told reporters.

March 13, Huanghua International Airport and the only base of our province of Hunan Branch China Southern Airlines inform all business partners, claiming Hunan Civil Aviation Regulatory Office received notice of the decision to suspend with immediate effect lithium battery collection, transportation and related products; mobile phones and portable Remove the computer such as lithium batteries, can be at normal operation, lithium batteries and related products to restore the transport time to notice. Have now issued an "off the lithium" notice and begin to implement the domestic airports, including Guangzhou, Changsha, Wuhan, Guilin, Jinan and Zhengzhou and other places.

Industry analysis, once the air transport official of the lithium battery of electronic products to say "no" in the short term domestic air logistics industry and the electronics industry will be seriously affected. As small high-value electronic products, rapid fluctuations in market prices, much needed air transportation, if all be transported by train or car, the industry's turnover rate will slow down quickly.

Reporter noted that the current Southern and Huanghua International Airport on passengers carrying spare lithium batteries there is no clear limits, because lithium batteries used in a separate risk is not high. "Lithium batteries are rechargeable and can not be charged, etc., of that in, we will soon publish a detailed standard out." Branch in Hunan China Southern Cargo, said the current operation, if the international authority of professional security certification, can receive transportation.

Nokia C5: Cheap S60 mobile angetestet

Nokia C5: With full-fledged navigation for lukewarm: VGP-BPS5A , sony vgp-bps9a/b , sony vgp-bpl9 ,sony VGP-BPS13 ,GP-BPS13A/B ,VGP-BPS13A/S ,VGP-BPS13B/B , sony VGP-BPS13/S , sony VGP-BPL13 , etc.

With the C5, the first Nokia phone sends its new C-Class into the race. At the Hanover Fair CeBIT (was) 2 to March 6, the device presented, with the successful Nokia's S60 user interface works, and will begin shipping during the second quarter for just 169 Euro without a contract. A Value-hit, on the worth the wait? The editors of the CHIP mobile world provides the answer, because she has tried a pilot series of C5-spot already.

1. Facts

C stands for Classic and it appears the C5 in the classical format with bar display and built-up including control and numeric keys on the front page. The specified level of 112 x 46 x 12 mm corresponds to a S60 phone with an open operating system compact size. In addition, it weighs only 89 grams As a special Nokia has released the C5 for its world-free navigation ‘Free Ovi Maps' (Ovi Maps 3.0.3). Both the application and an A-GPS receiver is integrated. This novelty is trimmed to social network services: client for Facebook, My Space, the Google Talk Instant Messenger and Windows Live and e-mail services Ovi Mail, Google Mail and Messaging Nokia stand for an extensive exchange with friends over the web. Internet Connections builds the C5 in the HSDPA speed on over the mobile network and also sets the mail sent via HSUPA for speed. A 3.2-megapixel camera, a media player, a radio feature and a jack for standard headphones and an expandable memory round out the multimedia division from.

2. Practice

The C5 looks neat and fits comfortably in your hand. The pre-series was already well-made. Although the battery cover is made of plastic, makes the phone not a cheap impression. To value the appearance, accentuated by the chrome parts on the front as the frame. The control and numeric keys respond when typing and navigating through the menu already fixed and precise. The number keys are well separated from each other. Only the distance between the soft and hard keys failed Nokia optimal: When trying out there were some mistakes. As for the screen: At 2.2 inches, it comes out on video and web site rather small, but is usual in this classic mobile phone format. The resolution of 320 x 240 pixels is more time for today's minimum requirement. Still worked on our test device that quickly clips or streamlined menu yet practicable.

The menu we could not test that C5 is during the fair days chained to the display table. But the mere fact that the device is the world's free signposts by car and foot support is a big plus. It also appeared in the Navi practice test of the CHIP mobile world very purposeful. The internet access worked on the C5 in the first check also quite fast, the mobile website of CHIP Online built the system in about 20 seconds. The 3.2-megapixel camera took a good first impression, as does the music player. The real quality is, however, only show the full test.

3. Assessment CHIP mobile world: apple Ibook g4 power adapter , apple macbook pro power adapter , apple powerbook g4 power adapter , apple macbook pro 17-inch battery , apple macbook pro 15-inch battery , apple macbook pro 13-inch battery , Apple Macbook Pro battery , etc.

Lack of Wi-Fi, 3.2-megapixel photo resolution to be limited, not a very high-quality housing material: Here you find that Nokia has set the red pencil. Here, the C5 is not a cheap knock-offs. It offers an attractive Rundumschlag, is also relying on free navigation, and thanks to Symbian OS open for tens of additional programs. A commendable package that makes sure that a nerve with many users. The MSRP of 170 Euro will be undercut by free traders still safe. All images plus first live images, see the photo gallery. Who does not want to wait and rather looking for a cheap S60 with touch screen, which comes to 5230 from 125 euros without contract in question. It also supports the free navigation. (wh)

China's economy is still expected to maintain a rapid growth

Last Friday, the PBOC issued the 2007 fourth quarter monetary policy implementation report indicates that economic performance in 2008 as international and domestic uncertainty increased gradually emerging effects of macro-control policies, economic stabilization and moderate growth is likely to slow down high , but economic growth shifted from growing too fast yet fundamentally alleviate the situation of overheating, inflation, increased risk; rapid investment growth momentum is expected to ease, but will continue to maintain rapid growth.

In this regard, first futures analyst Liu Guanyu that, in the U.S. economy by the sub-debt crisis situation and gradually increase, with China emerging countries, led by the extent to which able to maintain rapid economic growth, thereby offsetting the economic slowdown in developed countries with to the impact of paramount importance. As the world's major powers of steel and the largest developing country, China's sustained economic growth, will include metal commodity prices, including vital support.

Short-term supply and demand change and global impact of inflation expectations

China snowstorms on the impact of non-ferrous metal production in the most recent market attention. Wing Futures certain analysts believe, given the power restoration and reconstruction work after snowstorms in full swing, the demand for power grid reconstruction is full of stimulating demand for copper look forward to. He said that the market for short-term concerns about the shortage of domestic supply capacity as non-ferrous metal prices, strong domestic support.

Great: acer aspire 3000 battery , acer aspire 3500 battery , acer aspire 3680 battery , acer aspire 5000 battery , acer aspire 5550 battery .

In addition, the short-term changes is also reflected in the changes in the supply. First, LME copper stocks continued to decline. From the beginning in January LME copper stocks continued to decline, as of February 20, the Stock Exchange stocks fell to 137.6 thousand tons, one and a half months to reduce inventory by 6.3 million tonnes, decreased by 31.5%, and the cancellation of warrants of up to more than 30,000 tons , which indicates that stock exchanges may continue to decline, the market interpreted this demand. Followed by the supply of copper concentrate shortages. Power shortage this year, not only for the impact of domestic industrial production, Chile, Zambia, South Africa and other major producing countries of metal mineral resources have also emerged in power shortages. Early February, Chile, said the tight supply of energy may lead to the country's GDP growth this year dropped by 0.5% -1% to 4.5% -5.5%. Encountered more than 50 years due to a rare drought, Chile, the domestic reservoir water level dropped, while the supply of natural gas used for electricity generation is also a shortage.

Global inflation is expected to support the metal prices have also become an important reason for higher short-term. Maike Futures analyst FJLIANG that the increasingly high cost of production makes the price of copper in the bottom of the constant uplift, while the continuing decline in purchasing power of money making more and more money to buy commodities to avoid risks, which also increased the price of copper up possibilities.

Makings of a legend?

The HTC Legend has won the place of the current best Android phones in the ranking. Despite the somewhat weaker equipment, the Legend can defeat even the much-praised Nexus One - why, you betrayed our test.

HTC Legend: Currently best Google phone: Fujitus Battery , Sony Battery , Apple Battery , Acer Battery , Dell Battery , IBM Battery , Toshiba Battery , etc.

The Legend is the official descendant of the successful HTC Hero. With the latest version of Android 2.1, an improved display and much more noble outfit takes the legend in the footsteps of the hero and joins in the ranking significantly further a front. Incidentally, it creates a legend even in Google’s top dog Nexus One (U.S. version) by improved mainly because of the ergonomics.

Fast in all respects

Although the legend has to be content with a 600 MHz processor, but in practice it is hardly a performance difference between the Nexus One (1 GHz) and the Legend noticeable. Even when multiple programs are running simultaneously, the work rate remains at a high level. Also, the display responded quickly in the test. This fix changes from portrait to landscape mode and increases or the image in the multi-touch operation, so the zoom using the separated or reduced contraction of two fingers on the display, fast. Also the kinetic scrolling works well in Legend.

Mobile surfing, you can use HSPA up to 7.2 Mbps for downloads and up to 2 Mbps for uploads. In practice, the browser presents a good pace. In about 12 seconds a default page (Chip.de) was fully loaded. Thanks to USB 2.0, the Legend also puts down during data transfer via USB cable a good time. In less than a second title transferred an MP3 from the computer to the phone.

Input: optical trackball mouse instead.

Although absent from the Legend of the sophisticated voice recognition of the nexus, and it offers no factory nicely animated wallpaper. However, the phone has something on the box: Android 2.1 is even more on social networks and has some nice visual features. In addition to the Legend, the donated HTC’s own user interface Sense. Here you can use, for example, the function “Friend Stream”. This allows contacts, phone numbers and Social Networks and join the user will be informed about news always on request from the respective networks.

Legendary sharply

OLED is the magic word and the Legend. The 3.2-inch display gives the information you knackscharf and above all with impressive brightness and contrast. In addition, designed as a capacitive touch screen display responds quickly and precisely to the input via a finger. Even the very small type of the virtual QWERTY keyboard with a little practice can use quickly and accurately. When Legend HTC replaces the mechanical trackball with an optical mouse, which responds to the Darüberfahren with a finger. This works in practice, although not quite as precise.

A built-in light sensor agrees with the corresponding display brightness from the current conditions. This saves energy. Speaking of energy or battery life: Again, the Legend can be seen. At full power GSM stood at the end just 3 hours and 40 minutes on the clock.

Camera: VGA video and images with 5-megapixel.

In the case of the HTC Legend is starting to work a microSD card with 2 GByte. The internal memory of the mobile phone holds about 200 megabytes. To remain around 2.2 GB for your music, photos or videos. If that is not enough that can upgrade up to 32 GB via memory card. The music player uses its full potential on the attached earphones is not full. The factory headset brings the sounds only half-cooked on the ears. Thanks to 3.5 mm jack, you can also anstopseln own, higher-quality eavesdropper. Then it just sounds a lot better. The sound image can be due to missing or an equalizer presets do not change, but the Android Market offers here many free applications.

Images shot using the Legend 5-megapixel camera. In the current version of Android amateur photographers to get a few more functions to the source - such as the adjustment of contrast, color saturation and sharpness directly via e-scale setting. Also features like geotagging and Flimmeranpassung can be utilized. On the whole, the photos can be seen of the Legend in daylight conditions, when strikes a somewhat irregular edge distribution (see photo gallery). Videos are recorded in VGA format (640 x 480). Our acoustic test mastered the Legend with quite good performances. The voices always sounded natural and pleasant loud. Only the Handsfree placed at the intercom blared out occasionally and tidy at full volume.

Portable Device Information A

Mobile phones, multimedia players (PMP), MP3 players, digital cameras, portable video game consoles, personal navigation systems (PNA), etc., these popular consumer favorite portable consumer electronics products, a basic problem is: their functions become increasingly diverse and increasingly sophisticated dimension, but the increase in energy density batteries can not keep up much faster and ever-increasing complexity of the power requirements of portable devices, and people still want to be able to charge the case of a longer time interval, take advantage of these short, light, portable consumer electronics to enjoy mobile entertainment and mobile communications. In particular, the integration of these products feature the trend, for example, with a camera and camera-enabled mobile phones, personal digital assistants (PDA), Global Positioning System (GPS), MP3 and video functionality into a smart phone, further exacerbating the problem severity.

Business: fujitsu lifebook s6000 battery , fujitsu fpcbp80 , fujitsu fpcbp80ap , fujitsu lifebook e8310 battery , fujitsu lifebook e8210 battery .

Another trend of portable devices is to add high-capacity micro-hard drives, so smart phones, PMP and so on with high-density storage capacity. Used in most of the hard drive has a diameter of 1 inch or smaller discs in the disc rotation speed up the process, the peak current demand may be as high as 500mA, this is undoubtedly to the tight power budget even worse. 2.5-inch, 3-inch or even 5-inch color lcd screen makes the gradual introduction of a highly efficient LED backlight and the LCD bias power supply continues to be closely watched | Regulators management techniques. In addition, MP3, PDA, GPS devices and laptop computers widely used USB interface, both data transfer and charging a single miniUSB interface to become the future development trend of mobile phones, which also requires a new battery management and power management chips.

Fortunately, the continuous development of power management technology is to meet the portable consumer electronics products to the battery life, functional integration, reliability, form factor and cost of these events from conflicting application requirements. For example, using the power path management technology, battery charger IC allows to charge the battery at the same time operating system; combined switching regulator and LDO regulator advantage of the new power management IC to further improve the power conversion efficiency; dynamic power conditioning technology effectively improve efficiency in the use of load power; Power Management Unit (PMU) is in a very small area where integration of almost all power features, to minimize the power system footprint. This article will focus on products for portable consumer electronics applications, battery charge management IC, LDO, DC / DC regulator, PMU, LED power driver IC power management techniques such as the latest trends and solutions.

Power path management technology to meet the demand for electricity supply while charging and load

Most of portable consumer products generally are available through an AC adapter, a USB cable or a Universal Li-Ion / Li-polymer batteries to power. Sometimes people want to charge to the device while continuing to watch video, phone, or play games. To meet the charging process in the system, high-current requirements, it is likely the charge current is relatively small, resulting in inaccurate charge management directives phenomenon. Therefore, the supply of power between the path management is very important.

Linear Technology's LTC3555 to resolve these problems, it has AC adapter, USB cable and lithium-ion batteries seamlessly between the power path management, and follow the standard USB power. The chip also has an offer of up to 1.2A charge current of a fully functional lithium-ion / Li-polymer battery charger, as well as three high efficiency synchronous buck converter (used to generate the majority of USB peripherals require low-voltage rails ). LTC3555's power transmission method is different from the existing battery and power management IC (the latter is the charger feed system). In such systems, the external power supply is not directly power to the load, instead of using AC adapter or USB port to recharge the battery, then battery power to the load. If the battery is deep discharged, then the load was in power there will be a delay in the process. This is because the battery charge amount to obtain the required minimum can not be before the draw power from it. LTC3555 can be used to eliminate the delay, allowing portable devices to a wall adapter or USB power supply immediately after the power-on access. In addition, the chip will also load all of the available unused power is used to charge the battery.

"It can bring two advantages, namely, to eliminate charging delay, and allow the battery charging and load supply at the same time, thereby prolonging the effective functioning of the application time, and when connected with the USB cable to speed up the charging speed. This power management Another advantage is that method can be used in the AC or USB power supply situation to improve efficiency. "Linear Technology Product Marketing Manager Tony Armstrong said.

In addition, mobile phone charger and interface technology standardized in line with people's needs, a single miniUSB port for data transmission also used for both power and become the future trend of development. TI's single-cell lithium-ion battery charge management IC BQ24070 precisely to meet this need. As a TI high level of integration bqTINY-III series of charging and system power management device 1, which integrates 2A AC power switch, 1.5A charging FET, current sensor, reverse blocking protection and thermal regulation such as battery-management functions. It uses TI's dynamic power path management (DPPM) technology, can be supplied to the system while independently charging the battery, and according to the system voltage dynamic adjustment charge current.

TI's high-performance analog products senior marketing engineer HE Xin Long introduced the Road, "BQ24070 support a single miniUSB interface automatically selects AC Adapter or USB-powered, and can choose different according to different charging rate of power supply. When the power supply shortage The charging Wi-Fi, Bluetooth and mobile TV and other functions that require momentary high-current, the battery power can be added. "

In recent years, multi-function battery-power management IC affordable battery charging, DC / DC conversion, battery protection, battery monitor or power supply options. For example, TI's TPS65800 also USB port and AC adapter power supply to provide a flexible charging and system power path management. It by the Li-ion or lithium polymer battery-powered applications, also has more power output and several circuit choices. TPS65800 in a separate charging the battery when the power supply system also reduce the battery charge and discharge cycles. It automatically selects the USB port or AC adapter as the system's power. In the USB configuration, the host can be set in the pre-charge rate of 100mA, and 500mA choose. IC based on the system load on the USB charge rate dynamically adjusted to maintain the charge rate of 100mA or 500mA.

Microchip's MCP73811 and MCP73812-type (MCP7381x) Lithium-ion / Li-polymer charge-management controllers also provide fully integrated charge-management functions, as well as up to 500mA selectable or programmable charge current. They are compatible with USB, also equipped with integrated current sense, pass transistor, as well as on-board reverse-battery protection. MCP7381x charge-management controller is compatible with USB output-power specifications, the majority of personal computer through the USB port to take power without the need to connect an external power adapter. In addition, these devices have on-chip thermal regulation function, can be reduced when the temperature rises above safe levels of charge current.

The battery recall and IT Industry

The battery recall and IT Industry

Battery Li-ion battery recall sweeping the IT industry, a tough 15-year spread

Sony laptop battery recall incident a year later, a similar incident once again plagued Japanese home appliance businesses, the protagonist of this incident is Matsushita Electric Industrial Co., were recalled product is the cell phone lithium battery, this incident also shows that the battery industry is facing a The enormous challenge.

Recalled the most number of record industry's: fujitsu lifebook t5010 battery , fujitsu fpcbp200 , fujitsu fpcbp200ap , fujitsu fpcbp136 , fujitsu fpcbp136ap .

Nokia Tuesday announced that part of the Matsushita-made lithium-ion batteries overheating problems, the company will take the initiative to recall these products and for the user to replace the battery, it is learned, and the recall of events up to 46 million mobile phone. It is not clear that the company would recall and replace the number of batteries, but the number of recalled Sony batteries are projected to more than four times higher than the incident has become the industry's largest battery recall incident, together.

Since August last year, Dell announced that Sony held a large-scale production for notebook computer lithium-ion batteries, the battery industry has been plagued by such incidents. Almost all the major computer makers have announced and recall of Sony laptop batteries, while Sanyo Electric has recalled over mobile phone batteries and notebook batteries.

Battery recalls continue to occur on the one hand reflects the business-to-consumers more prudent and responsible attitude on the other hand also shows that the battery there are still many problems in production. Rechargeable lithium batteries in the past 15 years has been a laptop computer and cell phone industry, one important factor in the rapid development of lithium batteries is relatively cheap, light weight, environmental performance is good, much better than nickel-chromium batteries.

On the other hand, lithium battery current generated by larger, more complex manufacturing processes, heat and even easier to overheat, short circuit occurs when the consequences are more serious. Last year, some Sony laptop battery fire incidents have occurred. The recall Nokia Panasonic lithium battery allegedly occurred because the battery charger overheating.

It hard to recall the aftermath of the incident: fujitsu lifebook t4000 battery , fujitsu lifebook t4010 battery , fujitsu lifebook t4020 battery , fujitsu lifebook t4210 battery , fujitsu lifebook t4215 battery .

Mobile phone industry and the notebook computer industry's rapid development has exceeded the pace of development of battery technology, product features but also increasingly improved battery performance higher and higher requirements.

Lithium battery incidents occur frequently prompted some manufacturers to take a more cautious attitude. Toyota hybrid vehicle delay in the use of lithium battery plan. Nevertheless, industry experts still believe that despite the limitations of lithium batteries, but in the foreseeable future, it is still the most practical battery technology.

Sony announced this week that the company will spend 97.6 million U.S. dollars in Singapore to build a cell phone battery manufacturing plant in order to consolidate its market share. The plant will use more advanced lithium-ion polymer technology, the factory is expected to be operational by August next year, the initial monthly production capacity will reach 1 million by 2010 will reach eight million. Toshiba's ongoing efforts to develop alternative energy technologies, such as fuel cells, this battery does not use chemicals, but the battery for commercial still have a long way to go.

Panasonic is currently the world's four largest manufacturers of lithium batteries, the company said its the battery problem is generated in the manufacturing process. When used with an insulating layer to prevent short circuit damage occurs when the overheating arises. Nokia said that so far, Panasonic lithium battery overheating problem caused by only 100 cases were reported, but no serious injuries. However, Nokia will continue to take preventive measures to replace all the production date of December 2005 and November 2006 between the same origin as the Osaka battery.

Panasonic is expected to bear most of the costs to replace the battery is estimated to cost up to 170 million U.S. dollars. Affected by this news, yesterday in Tokyo Stock Exchange, Matsushita shares fell nearly 5 percent, to close at $ 2015.

Fuel cells and raw materials

Predicted in 2007 gasoline prices Dell Latitude D610 Battery will increase 27%. Supply disruption in Nigeria, Iran’s nuclear problem may be caused by interruption of oil exports, as well as declines in U.S. gasoline stocks since April 2006 prices increased significantly. Brent oil price from 66 U.S. dollars / barrel soared to 73 U.S. dollars / barrel. Oil prices in 2007 is expected to be raised to 63.7 U.S. dollars / barrel. According to a variety of ways to predict, in 2010 China’s natural gas consumption will reach 1000 × 108 Lifang Mi / a about.

China’s methanol consumption in recent years has maintained rapid growth momentum, 1998 and-2004 average annual growth rate of 15% in 2004 to 5.73 million tons, while domestic methanol production over the same period was only 4.406 million tons, showing the situation of short supply. But the future of new methanol production capacity can quickly enlarge, thus reversing the supply and demand. Is expected in 2010 China’s methanol production capacity reached 15 million tons in 2015 will reach 24.1 million tons. The demand side, formaldehyde, methanol consumption is still the main driving force is expected in 2010 will consume four million tons of methanol, in addition to acetic acid production capacity in 2010 to reach 3 million tons required to consume 1.9 million tons of methanol, combined with MTBE, and other downstream products the needs of development status of China’s methanol demand in 2010 is expected to reach 12.3 million tons in 2015 to 24.5 million tons (The above data comes from coal Network). To preliminary statistics, China’s current project under construction or official of the methanol project in less than 50, the methanol project under construction production capacity more than 4 million t / a, while the proposed methanol plant and planning capacity of more than 20 million t / a. If the projects Dell Latitude D620 Battery are all carried out in accordance with the planning, then (of course, a lot of projects in the planning stage only), the next two to three years may be focused on the situation of heavy volume, which will have a major methanol’s future price of negative effects. In addition, most new projects are concentrated in the central and western areas, which will lead to a regional excess of methanol supply problems.

“Made in China” to change the market structure

Domestic battery sweep pattern of the Chinese market is clearly inseparable from its efforts over the years. In order to rewrite the past, Japanese-brand batteries rampant in the Chinese market situation, South-fu, Double Deer, White Elephant and so provoked the burden of domestic battery brands to create a scientific and technological innovation “Made in China” journey. Which ranked top in the domestic market of South-fu batteries, but also by virtue of a powerful “Plant science research” independent innovation mechanism, in the process, technology, product innovation and other aspects of comprehensive research and development, become the largest alkaline battery brands.

Philosophy of environmental protection from a sense of responsibility with Dell Latitude D820 Battery

The overall rise of China’s battery business benefited from strong corporate social responsibility. Domestic battery is no longer based on the current corporate cost of pollution to the environment to develop business, but through the “green revolution” to win customers and markets. Back in the early 90s of last century, the Chinese battery manufacturer with a sense of responsibility and mission to begin the process of environmental protection battery production. Like Nanfu, through independent research and technological innovation, the success of transformation out of the world’s most advanced production lines, and in 2000 the first full realization of alkaline manganese batteries mercury-free products. Fu, etc. in the South under the leadership of a number of enterprises, the domestic many large companies also have the battery began to restructure production of environmentally friendly energy saving alkaline Dell Inspiron 6000 Battery.

Can be said that the success of China’s battery production companies, not dependent on the cheap “Made in China” and the international brand price competition, but through constant innovation in technology and market, through the international standards of quality and Dell Laptop battery marketing have won consumers and market.

Domestic battery has become a climate

From a professional Dell Battery web site evaluation on disposable batteries results, Nanfu, Deer and other domestic brands is very obvious advantage of the battery, discharge the battery duration is superior to four times more than Japan’s Toshiba. China’s rapid rise of the battery brand and its efforts over the years is clearly inseparable. In order to rewrite the past, Japanese-brand batteries rampant in the Chinese market situation, South-fu, Deer and so provoked the burden of domestic battery brands to create a scientific and technological innovation “Made in China” journey.
