Auto manufacturers collaborate on harmonized electric vehicle fast charging solution for U.S. and Europe


Dearborn, MI, U.S.A. — (METERING.COM) — October 14, 2011 – Seven auto manufacturers, Audi, BMW, Daimler, Ford, General Motors, Porsche and Volkswagen, have agreed to support a harmonized single port fast charging approach for use on electric vehicles in Europe and the United States.

The system is a combined charging approach that integrates 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 companies to share the same fast charging stations.

The seven manufacturers have also agreed to use HomePlug GreenPHY as the communication protocol. This approach will also facilitate integration of EVs into future smart grid applications.

The manufacturers say they 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 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 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 electric vehicles into the smart grids.
