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 electric vehicles from Audi, BMW, Daimler, Ford, General Motors, Porsche and Volkswagen can share the same fast charging stations.

The seven auto manufacturers 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 United States 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.

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