That's quite the difference between wall-kW and battery kW! About 30% more!
Hmm... ~0.3 of that is the accessory battery. So actually about 25% more for just the traction pack.
~10% lost at the chargers. ~10% lost for battery charging efficiency. I suppose the other 5% could be accounted for by charging voltage ~156v+ vs the 150v approximate I was using.
Ok, nothing unusual going on here. But I'm dang glad the chargers are as efficient as they are, or this could get ugly!
Anyway, that puts me at ~2 cents per km electric, vs ~8 cents per km in my gas version.
Time to add a fuel log!
