CHAdeMO officially recognized as international DC fast charging standard published by IEC

The CHAdeMO protocol has been officially recognized as an international DC charging standard by the International Electrotechnical Commission (IEC), a leading global organisation that publishes international standards for electric and electronic products and related technologies.

Since 2009, following the commercialization of the new generation of EVs that were fast chargeable using the innovative CHAdeMO technology, CHAdeMO Association members have been taking an active role in the IEC technical committees 61851-23, -24, as well as 62196-3 in order to drive the consensus approach of international standardisation.

After 4 years of expert meetings, in January 2014, the FDIS (final draft international standard) for 61851-23 and -24 were approved by the committees and were finally published on the IEC website yesterday.

DC fast charging system standards IEC 61851-23 gives the requirements for “DC chargers” and provides the general requirements for the control communication between a DC fast charger and an EV. IEC 62851-24 defines digital communication between a DC fast charger and an EV.

In all of the aforementioned technical committees, CHAdeMO is among the 3 different systems that were approved to be international DC charging standards: CHAdeMO proposed by Japan (System A); GB/T by China (B); COMBO1 by the US and COMBO2 by Germany (C).

As of 14 March 2014, there are 3,605 CHAdeMO DC Quick chargers installed worldwide: 1,967 in Japan; 1,072 in Europe; 554 in the US; and 12 other places.

Higher capacity (120+ KW) connections will have to be developed and standardized for future extended range BEVs with 160+ kWh battery packs.
