My Kia also has a normal 12v battery for normal car stuff in addition to the main battery pack. But it uses the main battery to charge the 12v if that ever gets low while parked

And that a simple trick that Tesla still don't have implemented, to my knowledge.

That is false. Teslas maintain charge on their low voltage battery from the high voltage battery, just like every other EV

It is a good thing they changed then. I have multiple acquaintance who own Teslas who got locked up of their car because of the lack of this feature.

The low voltage battery can fail to the point of the car becoming unresponsive, including the electronic door handles, but not because it lacks automatic charging for the auxiliary battery. That has been a feature of every Tesla since day 1

I don't know that much the architecture behind Tesla cars, but the door handles thing is what kept them out. And the fact that the low voltage battery as you call it was a pain to replace.

[–] [email protected] 1 points 10 months ago

Yeah. The doors require power to open, and that includes the hood, which is where the auxiliary battery is. If it fails, there are wires you can pull out from the towing hook port which will activate the hood latch when external power is applied. It’s not great, but I’ve seen worse on gas cars
