Charging Standards Soon to be a Reality


Eight of the world’s leading automakers would be meeting at the EVS26 event in Los Angeles to work together in finding a single-port DC fast charging mechanism meant to make the system easier and faster for electric vehicle charging of the future.

These automakers include Audi, BMW, Chrysler, Daimler, Ford, General Motors, Porsche and Volkswagen, and are moving to support a standardized single port fast charging system known as DC-fast charging with a Combined Charging System in both the United States and the European Union.

This system utilizes a one-phase AC charging together with a fast three phase AC charging set up. At home, it would be using DC charging and an ultra-fast DC charging system for public chargers. This would allow EV owners to charge at most existing charging stations regardless of the power source.

The design came after review, analysis and collaboration from a number of current charging systems together with the preferences of U.S. and European customers. This charging system would be developed for all vehicle markets in an effort to create a uniform standard for all the participating automaker vehicle platforms. This was also chosen by the Society of International Engineers due to its harmony and fast charging capacity. Furthermore, the International Society of Automotive Engineers picked the Combined Charging System as the standard to exponentially extend type-one AC charging platforms.

On the other side of the Pond, the European Association of Vehicle Manufacturers also chose the system as an AC/DC charging interface to be implemented for all new electric vehicle types starting from 2017.

It is expected that the harmonized fast-charging system would help accelerate the development of EV infrastructures for the market, as well as able to reduce the overall costs for owners. This would hit the market later this year and the first vehicles that would use this technology would become available starting 2013.
