But don't forget the losses in charging the battery as well.

  That's about 10%, and it's all heat. So to charge a 90kwh battery, you need roughly 99kwh of energy. Which for me, since it's charging in my garage, the excess heat is actually kind of nice as it will keep my garage slightly warmer in the winter and thus my house as my garage is on the lower floor. Either way, it's still WAY more efficient than any time of combustion engine. Including hydrogen. Hydrogen is kind of a wasted effort (unless we are doing fusion ;p )
