@dalias @tinker sure but custom charging circuits is a serious business, and also you need enough for the whole pack.
My leaf is ok as a 2nd car, but 24kwh only gets me 50mi as its aging, and worse in winter. That's only useful as a short daily commuter and could never be our only car.
I'm not saying it's impossible, as I've never designed a 10x kw charging circuit, but I'd be very sceptical it's worth adding a few 100 w solar for charging a car unless it's a go cart or as a novelty...
