For the Volt which has RE motor, I probably agree. However, I think Spark EV really should have a 6.6kW charging instead of 3.3kW. W/o DC charging widely available, I find that using Level 2 EVSE at 3.3kW to be hard to justify when I need a very fast recharge. The keyword being fast; 7 hrs. on Level 2 is faster than Level 1 but not against 4 hrs. on Level 2.
That is really disappointing to hear, even w/the Volt. It really helps to have a higher wattage OBC so that one can pick up more charge within a given amount of time when opportunity charging as well as allowing for quicker turnover of spots (e.g. workplace charging). We have a number of Volts at my work but only 2 or 3 Spark EVs.
I've started sessions for plenty of Volts at my work on our L2 208 Volt Chargepoint EVSEs. They only pull ~3.1 kW from the wall vs. 5.7 to 6.0 kW of my '13 Leaf and ~6.2 kW for the Tesla Model S cars at work. Just recently, my work installed 4 Tesla HPWCs (http://shop.teslamotors.com/products/hi ... -connector
). I've not confirmed whether they're each on a 100 amp circuit. If so, that'd allow for 80 amp charging, which would be ~16.64 kW @ 208 volts.
