Eight car manufacturers from the United States and Germany will demonstrate fast-charging technology that will enable the recharging of most electrified vehicles with compatible systems in as little as 15-20 minutes.
Audi, BMW, Chrysler, Daimler, Ford, General Motors, Porsche and Volkswagen have agreed to support a harmonised single-port fast charging approach – called DC-fast charging with a Combined Charging System – for use on electric vehicles in Europe and the United States.
The combined charging system integrates one-phase AC-charging, fast three-phase AC-charging, DC-charging at home and ultra-fast DC-charging at public stations into one vehicle inlet. This will allow customers to charge at most existing charging stations regardless of power source and may speed more affordable adoption of a standardised infrastructure.
