I'm wondering if it's possible to have a dashcam or other 12v power using device that accesses the large battery. Also and if not, does the car notice if the 12v battery is getting low and charge the 12v battery with the traction battery? I do notice and perhaps obvious- one can while sitting in the car tap the power button twice on a hot day (no need hit the break) and turn on AC. The air conditioner can run for a very long time without a significant impact on the estimated EV range. It decrements the range but only slowly. Totally dig that when compared to a gas-mobile where one has to turn on the engine to run AC while waiting in a parking lot in the sun.
