A group of European and American car makers has announced the adoption of the J1772 standard developed by the International Society of Automotive Engineers for electric vehicle charging.
The single plug system is to be adopted by Ford, General Motors, Chrysler, BMW and the Volkswagen group (including Porsche and Audi).
The problem is that Nissan, Mitsubishi, Subaru and Toyota have already adopted a different “standard”, called CHAdeMO, which uses two plugs – one for home charging and another for fast charging.
The J1772 “standard” peg
won’t fit into the CHAdeMO hole
And, of course, Tesla is completely different again.
