That was great! You got about five miles per kWh, which is excellent (most Volt owners average about four miles per kWh). I expect GM to produce a better AC motor with up to seven miles per kWh , so the next BEv will carry a 30 kWH battery and reach the magical 200 mile EV range.
BTW, even if the Volt had a 6.6 kW charger, the EVSE will still have a supply limit, and your Volt wouldn't change faster. I expect to see in the near future some OEM or aftermarket business to sell an upgraded charger (maybe a 6.6 kW unit) for the Volt.
