The Society of International Engineers has chosen the single-port fast charging method as its standard for fast charging and the European manufacturing association (ACEA) has endorsed harmonization for all vehicle types.
The fast charging system was developed for all international vehicle markets and creates a uniform standard with identical electrical systems, charge controllers, package dimensions and safety mechanisms.
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 provide customers the convenience of charging at most existing charging stations regardless of power source and may speed the adoption of an affordable standardized infrastructure.
This is certainly an important milestone in the development of EVs. It is akin to standardization of fuel ports on petrol-powered vehicles.
The chargers will be available commercially by end of 2012 and vehicles using the technology will be available starting in 2013.
