Thanks for reading and commenting Amy. From experience, charging a 77 kWh battery from say 10% to full takes about 8-9 hours with a level 2 charger. A level 1 charger is about 8 times slower, so you can do the math. I think level 1 only works for a plug-in hybrid (that has a much smaller battery) or if you only drive short distances and recharge anyway.
