Yes, I oversimplified. I charge on a 30A circuit and will see a slow drop in SoC when preconditioning in single digit temps since the car's power demand is >6kW.Unless the power demand exceeds the power available from the onboard charger, charging circuit. This can happen in winter even when charging at 11.5kW. The heat pump draw + the stator heating draw can exceed 11.5kW. Any additional power needed has to come from the battery.
