Some detail on the upcoming Quasar 2 charger. Interesting that it is actually a “charger” rather than “charging point”, it bypasses the onboard charger. I wonder what DNOs will think about BEVs charging at 48A single phase?

Thanks for posting Stinsy, I've been waiting three years for such a package to come into the market place, but once again there is quite an element of uncertainty about when it might eventually be produced. Perhaps it's just as well that I've ordered a couple of storage battery's in the meantime!

48A = 11kW, and 3-phase domestic connections (which support 11kW domestic charging) are pretty common in Europe. The existing version of this for Chademo is 7.4kW and is capable of limiting charge rate so not to overload the grid.

The question of whether domestic V2G chargers will end up as AC or DC is an interesting one - VW have just announced that they'll support V2G via a DC link, and introduce an over-the-air update to support this soon (they have their own wallbox coming out to do the same thing), while others like MyEnergi think that AC links will be used. Personally I think DC link is the way to go since the control issues are much easier (already solved and implemented for fast charging), but it'll be interesting to see how it pans out.
