The huge majority of the time, all EV's will be charged at home, on a Level 2 charger. This "infrastructure" is already in place.
My brother just got a Mitshubishi i MiEV and his wife has been driving a Nissan Leaf for almost 6 months, now. They are sharing a Level 2 charging station and my brother often uses his Level 1, since his pack is smaller and he drives less distance to work.
EV's use their brakes much less often than ICE powered cars, since they have regenerative braking. So far, the "maintenance" on the Leaf has been software upgrades.
Doing the math comparing a Leaf vs an average 22.5MPG car, you save ~$17K per 100K miles driven; on fuel and regular maintenance. And buying the 85kWh Tesla Model S and paying $0.31/kWh (which is very high!) is virtually the same cost as buying and driving a full sized pickup truck or large SUV, if you drive ~200K miles on each. If you only pay 8-9 cents per kWh, then obviously, the "payback" distance is shorter.
