7 Automakers Collaborate on Harmonized EV Charging Solution

Taipei, Oct. 20, 2011 (CENS)--Recognizing the importance of a single international approach for DC fast charging, seven global automakers including Audi, BMW, Daimler, Ford, General Motors (GM), Porsche and Volkswagen have agreed on the combined charging system as an international standardized approach to charge electric vehicles (EV) in Europe and the U.S., according to Ford's recent press release.

The system is a combined charging approach integrating all charging scenarios into one vehicle inlet/charging connector and uses identical ways for the vehicle to communicate with the charging station. This allows EVs from the seven automakers can share the same fast charging stations. The seven carmakers believe the development of a common charging approach is good for customers, the industry and charging infrastructure providers. Standardization will reduce build complexity for manufacturers, accelerate the installation of common systems internationally and most importantly, improve the ownership experience for EV drivers.

The endorsement of the combined charging system was based on reviews and analysis of existing charging strategies, the ergonomics of the connector and the preferences of customers in both the U.S. and Europe. The harmonized approach – across both continents and all manufacturers - will provide a framework for future infrastructure planning as well as a communication protocol to assist in the integration of EVs into the smart grids. The seven carmakers also agreed to use HomePlug Green Phy as the communication protocol, which will also facilitate integration of the EV into future smart grid applications.

The harmonized EV charging solution is retro-compatible with the J1772 connector standard in the U.S., which has also been achieved in Europe where the system is based on the IEC 62196 Type 2. The approval of the J1772 standard has given EV owners the comfort of knowing they can charge at all Level 2 charging stations.
