Wow

Wow, so much idiocy in such a small article. Does the Reg have shares in BP or something?

European 'standard' e-car power connector details emerge

Thumb Down

Not so good

@ Richard: Induction is so inefficient you may as well use petrol.

@ Altis: The control pilot is for the data link.

I'm more worried about the whole 3 phase idea though. The plug is rated to 63A, so could, in theory, deliver a maximum of 20KW with a 3 phase source. However that's 2.5 hours to charge a 50KWH battery - so much for fast charge. Oh, and good luck trying to buy a 20 KW 3 phase charger that will cost less than the battery and weigh less than 50KG - Its kind of a dumb idea to have an on board high power charger.

High current (~600A), DC connectors will be the way forward, with a cheap, on board low power over-night charger that wont need anything fancier than yer standard kettle plug.
