Standard car battery
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.
