I am not familiar with Nissan Leaf. If it is a pure electric, with no gasoline backup, then of course you are right...mechanically it is a simpler design.

I have a friend who purchased a Leaf and the special fancy charger system for his home. The car arrived a week before the charger. After driving a bit, the car was sitting in the driveway with insufficient power to go anywhere. Absent the charger, he tried the 110 VAC charger cable. It blew the breaker in the garage that normally serves his washing machine. He was a very unhappy new Leaf owner with an expensive paperweight in the driveway. He hasn't had any complaints since getting the new charger. He did have thoughts of installing a solar electric system, but I'm not sure that is a winning proposition.
