I would think that during preheating/cooling the car while on L1 charging, you won't be ADDING any energy to your batteries, but I can't imagine that you'd be taking away from your SOC (State Of Charge). How much power does the heater/cooler really use???
ex. L1 charge provides 1000 watts to the battery for charging purposes (made up numbers!)
Heating might take 900 watts, leaving 100 watts (+100) going TO your SOC. (very little charging going on, since most of your energy from L1 is going to the heater.)
Cooling might use 750 watts, leaving 250 (+250) going TO your SOC. (a little more charging, but still not much)
Turn on heating, radio, NAV, fans on high, windshield wipers AND headlights, might use 1500 watts, leaving -500 watts coming FROM your SOC. (now, you're taking charge AWAY from your batteries and decreasing range)
Do we have any hard numbers yet on how many watts L1 provides for charge vs how many watts heating/cooling uses??
Most EV heaters for a vehicle cabin that size are about 1500 watts. A/C will be less (my guess is closer to 1000 watts), but I have not seen any numbers on the Leaf's System for cooling. For that matter I've not seen specific numbers for the heater either.
edit: this is why I wish there were seat heaters. I would not preheat the car but just turn on the seat heater which would use far less power than the cabin heater.
