Good Battery

In the electric vehicle symposium “EVS24″ on a number of organizations have on the plug-in hybrid (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 (Society of Automotive Engineers, SAE) introduced the respective standardization efforts, which include the standardization of specifications for connecting PHEV charging facilities and communications technologies 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 standardization activities carried out is determined by the two organizations aimed at harmonizing the views of “IEC / ISO JWG V2G (joint working group vehicle to grid)” organized and implemented. Well-known energy company RWE AG, Germany’s Ingo Diefenbach progress of the work of the organization delivered a speech.

IEC / ISO JWG V2G 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, 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 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 / ISO JWG V2G 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” (Ingo Diefenbach).

On the other hand, the U.S. research institutions, Argonne National Laboratory (Argonne National Laboratory) of the Theodore Bohn progress on the standardization of SAE delivered a speech. PHEV standardization, sony laptop battery ,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 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 / ISO JWG V2G differ materially from those discussed in, “We hope that mutual compromise” (Theodore Bohn). 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 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.”

Standardization of car batteries

With regard to the standardization of the battery, Erasmus University College Brussels, Belgium’s Peter van den bossche on the current progress, gave lectures. At present, the standardization of automotive batteries, including lead-acid batteries standards IEC60254, and battery as a whole related 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, ISO TC22 SC21 is developing with the vehicle’s rechargeable battery system, the relevant standards, and IEC TC21 are being rechargeable battery units and modules in order to focus on the development of relevant standards. Scheme “will continue with the IEC, ISO and other groups repeatedly discussed” (Peter van den bossche). In addition, intend to discuss in future lithium-ion capacitor standards.sony vgp-bps5 battery,sony vgp-bps5a battery,sony vgp-bps8 battery,sony vgp-bps9 battery,VGP-BPS8A,VGP-BPS9/B,VGP-BPS9/S,VGP-BPS9A,VGP-BPS9A/B,VGP-BSP13/S.
