CHAdeMO Wins IEC Standards Designation

chademoThe CHAdeMO electric vehicle fast charging protocol has been officially recognized as an international DC charging standard by electrical standards organization the International Electrotechnical Commission.

Since 2009, following the commercialization of the new generation of electric vehicles that were fast chargeable using the 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 January 2014, the final draft international standards for 61851-23 and -24 were approved by the committees, and were these 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 electric vehicle.

IEC 62851-24 defines digital communication between a DC fast charger and an electric vehicle.

In all of the aforementioned technical committees, CHAdeMO is among several different systems that were approved to be international DC charging standards. Japan proposed CHAdeMO, China proposed GB/T, the US proposed COMBO1 and Germany proposed COMBO2.

The number of global electric vehicle charging stations that use the CHAdeMO standard doubled in 2012 to more than 2,000 units, and will continue to grow, the CHAdeMO Association said in 2013. In 2012, the number of stations in the US alone grew from just 12 to 154. CHAdeMO says that is it currently the most widely distributed fast charging protocol in the world.

In August, the European Parliament proposed to only support CHAdeMO charging connectors being installed until the end of 2018. This means beyond 2018, EU member counties would install SAE chargers. There are currently more than 650 CHAdeMO chargers already installed in Europe, with more than 1,000 slated for deployment by the end of 2013, the draft proposal says.
