Dearborn, Michigan – Seven automakers have agreed on a combined charging system that includes DC fast charging as an international standardized approach to charging electric vehicles (EVs) in Europe and the U.S.

The automakers are Audi, BMW, Daimler, Ford, General Motors, Porsche and Volkswagen.

The combined charging approach 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 all seven manufacturers to share the same fast-charging stations.

Standardization will reduce build complexity for manufacturers, accelerate the installation of common systems internationally, and improve the ownership experience for EV drivers.

Endorsement of the combined system was based on reviews and analysis of existing charging strategies, the ergonomics of the connector and customer preference. The harmonized approach will provide a framework for future infrastructure planning, as well as a communication protocol to assist in the integration of EVs into smart grids. The seven manufacturers also agreed to use HomePlug Green Phy as the communication protocol, which will also facilitate integration of the EV into future smart grid applications.
