There has been a lot of bad press on electric cars - first - I'd buy one myself when funds come in.
Some state the grid would fail if many bought them. NOT!
I get Power Electronics Technology mag - yea into Electronics big.
The typical battery is less than 20kWhr.
Recharge in 10 hours on 120v line - and 4 hours on a 240v line.
Nissan states it differently - 220/240 at 40 amps.
Others like the Evr-Green 160 is a 16A 240v charger.
So until they get larger batteries the units will recharge in a shift of work or overnight.
Thought you should know what is going on.
