There have been some sporading discussion of the charging efficiency in various threads. I wanted to get your opinion in one thread.
I drove 32 miles yesterday from the dealer. Blink showed 13.58 kwh of charging at night - so it comes to 2.36 miles/kwh wall to wheels.
Assuming 80% charging efficiency, that would be about 2.95 mpkwh or some 71 miles range. If the efficiency is higher, say 90%, we are looking at just 63 miles of range (2.6 mpkwh). That looks a little low, given my freeway driving was limited to 55 to 60, even though the temperature was 30 deg and the climate control was consuming about 3 kw. I've seen a figure of 85% for charging (like Prof Bossel).
