I have owned no less than three Kia Soul EVs. The first two would succumb to a flat 12V battery, but the latest (a 2020 model) will connect the HV battery to charge the 12V battery if needed, even when the car is parked and switched off. You can see it in action, as a blue light on the dash will flash while this goes on.

Oh that's neat. I hope tesla adopts that, because one of the biggest issues has been the 12 v batteries dying quickly. I'm not sure if anyone's figured out the root cause, but IIRC people think that they abuse the battery in some way that an alternator wouldn't.

I'm surprised this wasn't thought of from the very beginning. Must be the Big Battery Lobby.
