[Oeva-list] Mercedes B-class DC charging

Actually you can barely see the AC symbol on 120 and 240 and the DC sign on the 400.  Yet another plug type.  An adaptor for the SAE combo plug should be really easy if Mercedes plays the same game with the signaling.

>>> That is what it is looking like. The manual says only 120/240 charging & everything I can find online about 400V charging is only European. Yet the sticker where the charge plug is it lists 120, 240 & 400V charging. I am assuming it is either an oversight by Mercedes or they are planning to support 400V charging with an update but is not available yet. I just can't find out exactly which it is or something else maybe.

>>>> I don't have an EV... yet!... but am a huge enthusiast. Someone related to someone I know bought a Mercedes B-Class electric recently. They were asking me questions since I talk about EVs a lot. I just don't know a lot of the details since I haven't owned one myself. Anyway, they said that the car shows it has the ability to charge at 400V but the connectors on 400V chargers don't match up to the connector on the car. I told them that 400V would be DC charging while the 120/240V is AC charging & they might need an adapter to do DC charging, but I am not positive on this. Mercedes website doesn't give details except that it will charge at 400V. Does anyone know if a b-class can be charged @ 400V and how to do it?
