What’ll It Be – CHAdeMO or DC Fast Charging Endorsed by SAE?

DC fast charg­ers will play a crit­i­cal role in wide­spread adop­tion of elec­tric vehi­cles, with their capac­i­ty to turn the charg­ing expe­ri­ence into some­thing much clos­er to a trip to the gas sta­tion than has been pre­vi­ous­ly avail­able. The tech­nol­o­gy isn’t new – in fact, it’s become com­mon­place in Japan. But where the automak­er is based has a lot of influ­ence over which sys­tem it prefers. A choice is being made between the Japan­ese CHAde­MO sys­tem, used by Nis­san and Mit­subishi, and DC Fast Charg­ing with Com­bined Charg­ing Sys­tem, endorsed by the Soci­ety of Auto­mo­tive Engi­neers and eight US and Euro­pean car­mak­ers.

Dur­ing a CHAde­MO Gen­er­al Assem­bly Meet­ing in Tokyo this month, appre­hen­sion was expressed over the con­tro­ver­sy. The com­bined charg­ing sys­tem was referred to as “the plug with­out the cars,” since it’s a new charg­ing stan­dard that will take time to arrive in the mar­ket, com­pared to CHAde­MO, which has been on the mar­ket since 2008 and has been charg­ing the Nis­san Leaf and Nis­san i-MiEV. The SAE is set to pub­lish guide­lines this sum­mer for the select­ed DC Fast Charg­ing with a Com­bined Charg­ing Sys­tem. The Euro­pean Auto­mo­bile Man­u­fac­tur­ers’ Asso­ci­a­tion is expect­ed to make a sim­i­lar endorse­ment.
