So long as it takes 8+ hours to fully charge the batteries at 240V and 45 minutes with a supercharger they will never replace gas vehicles.

Each 240V standard charge station takes a 40 amp breaker at 240V. Your standard house electrical panel is a 240V 100amp panel that already has a 30-40 amp breaker in it for the stove and 20 amp breaker for your Laundry dryer. 

So you and your spouse come home and both plug in your 32 amp chargers to recharge the 100km you each drove that day. Then you want to cook dinner while your kids use the computers, watch TV, etc. Not to mention your HVAC (furnace, AC, HRV, etc) equipment loads. OOPS, not enough power. 

And remember that the morons in power in places like Vancouver and Ontario want you to not use gas to heat your home and hot water and switch to electrical for this energy also.

You got between $4000-$10000 laying around to upgrade your home electrical service? You will need it.
