Three groups on the Car Battery Standard Time :2009-5-19 Source: The Internet Electric Vehicle Symposium “EVS24″ (2009 Nian May 13 ~ 16, Norway StavangarForum), the number of organizations have on the plug-in hybrid powered vehicles (PHEV) with the charging system, as well as lithium-ion rechargeable battery delivered a speech on the standardization. PHEV, the International Electrotechnical Standards Committee (IEC), International Organization for Standardization (ISO) and the American Society of Automotive Engineers (SocietyofAutomotiveEngineers, SAE) introduced the respective standardization efforts, which include the standardization of specifications for connecting and charging PHEV facilities, communication technology and systems. Standardization activities of these groups by German companies (ISO), French companies (IEC) and the American Enterprise (SAE) led the implementation.
Standardization of PHEV
IEC and ISO to achieve the PHEV charging facilities connected with the hp pavilion zv5000 battery standardization activities carried out is determined by the two organizations aimed at harmonizing the views of “IEC/ISOJWGV2G (jointworkinggroupvehicletogrid)” organized and implemented. Germany’s leading energy company RWEAG’s IngoDiefenbach progress of the work of the organization delivered a speech.
IEC/ISOJWGV2G set up two working groups (WG). One is the physical specifications related to WG1. Specific work includes discussion connectors, cables, both protection and power switch with the bottom and so on. In the more contentious aspects of the connector, compaq laptop battery,IEC envisages only be used to connect charging devices and cars, and made the maximum three-phase AC voltage of 500V, maximum 63A current and seven terminals (3 for power use, one for the ground use, two for the signals available, one for other uses) and so on.
The other is and communications technology-related WG2. The discussions included a more secure method of compaq evo n400c battery communication and communication services. Focus on the content of a clearly defined, while for the circumstances to determine their specifications and designed to ensure that the interconnected nature of the communication protocol. IEC/ISOJWGV2G will be 09 years, summarized the results of the above topics and to develop programs intended to vote in mid-2010, by the end of 2010 to develop the standard. Although the IEC and ISO observations seem more unified, but in fact at present, “there are still big differences” (IngoDiefenbach).
On the other hand, the U.S. research institutions, Argonne National Laboratory (ArgonneNationalLaboratory) of TheodoreBohn progress on the standardization of SAE delivered a speech. PHEV standardization, SAE specifications generally consists of two groups. Were used to connect to the specifications of PHEV 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 protocol, using examples and charging devices specifications. For example with the compaq evo n410c battery relevant provisions of the connector of the “J1772″, including the largest one-way 115V AC voltage, maximum 15A current and five terminals (two for the single-phase AC use, one for ground use, one for the signals available, one for the other uses). This IEC/ISOJWGV2G differ materially from those discussed in, “We hope that mutual compromise” (TheodoreBohn). Future discussions on the three-phase AC voltage up to 600V and 600A current and so on.
In addition, SAE is also envisaged through the power line communication (PLC) device to connect vehicles and charging compaq evo n400 battery facilities, and to consider the future, the vehicle information is uploaded to the Web network. “Because the next vehicle and the linkage between the intelligent instrument will become very important” (TheodoreBohn).
Standardization of car batteries
With regard to the standardization of the battery, Belgium ErasmusUniversityCollegeBrussels on the current progress of the Petervandenbossche delivered a speech. At present, the standardization of automotive batteries, including lead-acid batteries standards IEC60254, and battery as a whole related compaq evo n410 battery standards IEC61982. The latter also includes the per km for electric power 100Wh car battery standard IEC61982-3.
Based on these criteria, the group has started discussions in 2008 hybrid lithium-ion rechargeable battery standards. Lithium-ion rechargeable batteries, ISOTC22SC21 are being developed with the vehicle’s rechargeable compaq evo n600 battery system, the relevant standards, while IECTC21 with rechargeable batteries are being focused on units and modules to develop relevant standards. Scheme “will continue with the IEC, ISO and other groups repeatedly discussed” (Petervandenbossche). In addition, intend to discuss in future lithium-ion capacitor standards.
