Seven automobile manufacturers (Audi, BMW, Daimler, Ford, General Motors, Porsche and Volkswagen) have agreed to a single-port fast charging approach for use on electric vehicles in the United States and Europe.  It will be a harmonized DC vehicle inlet/charging connector for all vehicles made by these companies.  They also agreed to use HomePlug Green PHY as the communications protocol.  The standardization is beneficial to customers, the manufacturers, and charging infrastructure providers.  The new system will be backward compatible with the J7772 connector standard in the U.S. for Level 1 and Level 2 charging stations.
