It only takes 2 hours to regain 100kms of driving range on a level 2 charger.  I drive 80-90 km/day and can easily recharge overnight on an ordinary 110V outlet. Obviously, overnight charging doesn't conflict with my other activities and in some places qualifies for a time-of-use discount. BTW, this is on a 70 A service. I'd kill to have a full 100 A service. Then I could install a second dryer outlet which is all you need for a 240V charger. That is a few hundred bucks for a breaker, conduit, wire, box, outlet and professional installation.
