A few commuters to the little town I live in can charge their electric cars during the day while they are at work.
If every parking space had a 7 kW connection (230 V, 30 A single phase) almost all cars could be fully charged while their owners were at work. In fact even an ordinary 3 kW connection would be enough for most people; even my 2015 Tesla Model S adds more than 12 km per hour at 3 kW.

- DennisP 5y agoIf car owners are paying for that power, then you need more than just electrical outlets. You need something that takes payments. If car owners aren't paying for the power, then who is? And either way, what does it cost to wire up all the parking spaces?

I wonder how people ever managed to electrify street lamps, any exterior powered things, even the per-stall electric parking meters I've encountered.
- DennisP 5y agoCharging a car takes way more power than running a parking meter. All I'm saying is, the costs of these sorts of demand management measures for renewables should not be overlooked in comparisons with the cost of nuclear, which doesn't need them.
- WalterBright 5y ago> Charging a car takes way more power than running a parking meter. True, you'll need a heavier wire. And the cost of installing wire far exceeds the cost of the wire. When my house was wired up, the cost of the installation was 40 times the cost of the reels of wire.
