1) I read in a Car and Driver report about the Taycan that Porsche specifically told them the 93.4 kWh battery has a "usable" amount of 83.7 kWh. Two questions on this issue: a) Does that mean the 79.2 kWh battery loses the same amount of "usable" battery capacity, 9.7 kWh, or is it a percentage loss of usable battery capacity from 79.2 kWh? b) what is that 9.7 kWh of seemingly unusable battery capacity being used to do?
2) I know the 12V battery in the Taycan is used to power things like an ICE 12V battery. My question is what happens when the car is not moving down the road but you are running the AC, the radio, etc.? Is it taking power from the 12V battery or from the main battery system? Can you "empty" the 12V battery sitting with multiple draining components working and, subsequently, have a power issue? How does the 12V battery recharge itself? Is it though the main battery system or is it only recharged, for some reason, when the car is in motion.
Thanks,
