If you own your own home with off street parking, this is established and known technology. Still kind of expensive, but for example, I just got a new circuit for a charger, for less than a new circuit for an induction range.
The place we need to put the most effort into is rental places or HOAs with off street parking. We have the technology, we know how to do it, but there’s a mismatch between who pays and who benefits. It’s a people problem. If the landlord/HOA pays, how can we help them see the benefit so they’ll be willing to? Eventually this will solve itself when EVs become popular enough that people will be unwilling to rent or live there, but now it’s an obstacle. A purely human obstacle
