[quote]Wall to wheels efficiency is much worse than 90% (your 10%loss mentioned above translated to efficiency.).[/quote]
I was talking about the difference between the wall to wheels efficiency and the battery to wheels efficiency. That can very well be ~10%.
Your numbers seem very pessimistic to me. Particularly the AC to DC conversion. You can do much better than that.
If we want to compare real efficiency (including every step of the process), let’s do Leaf vs. Prius. Leaf goes ~80 freeway miles at ~25 kwh of electricity. Prius goes 50 freeway miles at 1 gallon of gas (=33 kwh of energy). It seems to me that Leaf is 2 times more efficient than Prius.
