Recharging an electric vehicle anywhere in the U.S. or in Europe may soon take just 15 or 20 minutes after Audi, BMW, Chrysler, Daimler, Ford, General Motors, Porsche and Volkswagen entered a deal to support a harmonized single-port fast charging approach. The global automakers will be having a live demonstration of this method, dubbed DC-fast charging with a Combined Charging System, from May 6 to 9 at the Electric Vehicle Symposium 26 (EVS26).
This combined charging system incorporates one-phase AC-charging, fast three-phase AC-charging, DC-charging at home and ultra-fast DC-charging at public stations into just one vehicle inlet.
As result, customers could charge at nearly all existing charging stations whatever the power source is. The adoption of a standardized infrastructure may speed up the process and may make the system more affordable too. The International Society of Automotive Engineers (SAE) decided to use the Combined Charging System as the fast-charging method for a standard that incrementally extends the current Type 1-based AC-charging.
This standard will be officially published in the summer. ACEA, the European association of vehicle manufacturers, has also chosen the Combined Charging System to be its AC/DC-charging interface for all the new vehicle types in Europe starting in 2017.
The charging system design was based on the collaborative review and analysis of current charging methods, the connector’s ergonomics as well as the preferences of U.S. and European customers. The Combined Charging System was made for all international vehicle markets and makes a uniform standard with identical electrical systems, charge controllers, package dimensions and even safety mechanisms.
