I wonder if enjoying air conditioning while recharging extends wait time to any extent?

DK. Have read that the battery may need to be heated or cooled for charging.

Sandpatch - Probably not a lot of extra time -From the forklift industry Lith-ion batteries were popular before I retired. lith-Ion batteries allow a lot of current to be applied in the charging process, without specific cooling 3/4 of the total amp hour rate of the battery is safe. This is how the batteries are recharged in so little time with the Tesla "superchargers". With known factors such as the total amp hour capacities the air conditioning in the car is likely using only 5% of the total, that's just a guess for sure. My guess is 5-10 min's if that.

Needa- Correct the Tesla heating and cooling system keeps things at closer the optimum temps helps charge and discharge rates in temp swings.

Our forklift batteries were very interesting using computer controls inside the batteries for controlling/balancing each cell. It would take me a few hours to replace a defective cell if the one that failed was under all the electronics. The charge rate capabilities (supper fast) allowed us to replace three lead acid batteries (needed for 24 hour operation) with one Lith-Ion battery. They can charge during worker breaks and lunch and shift change and never need watering or removal.

Refinements of this technology are coming along fast, one battery maker has prototype's in auto sizes charging at around 6 minutes from 20% to 80%

Needa - hope you didn't mind this in your thread
