A question for those of you guys who are more electrically astute than I.
Will I use the same amount of kWh of my home electrical power to charge my Leaf if I charge it using the 115V trickle charge cable, the 240V 3.3 kW charger, or the possibly future 6.6 kW charger?
In other words, are there efficiency gains to be made by using the highest capacity Level 2 charger and amperage available, or is the AC power usage equivalent regardless if which charging supply I use, as long as I don't mind waiting 20 hours for a full charge?
I realized that time-of-use rates will give me the most efficient cost per kWh if I charge during a brief period in the middle of the night, but I am talking about kWh usage, not monetary charges. I was told by a contractor that it is much more costly in kWh to heat a spa using a 115V supply than using a 240V supply. Does this apply to charging an EV as well?
