Yeuuup.
Gotta be able to turn the car ‘off’, and if the car is off (disconnected contact loop to engage the big battery) it cant receive the signal to turn on. (Connect the contactor to engage big battery)
So something has to always be on.
Which makes the big ‘fuel’ battery into a fancy alternator to keep the 12v/48v stuff on and running lol.
If you disconnect the tiny (in comparison) 48v battery from the main battery it wont charge and the car dies even if the big battery is fully charged.
Long story short, teslas fail to modern car problems but with the added bonus of failing to other dumb tesla-specific problems.
Seeing a heavy duty diesel tow truck haul a cybertruck is about as on-the-nose as you can get for the reason it sucks.
Lol when I get out of my car I park in the garage and plug it in. It stays plugged in till I need to drive again. No charging schedules since they shut down the 3G networks because reasons

Same thing happens with the Nissan Leaf, it has a 12v battery and it needs to be in good shape to start the car.
Frustratingly my phev ford did the same thing when I left it parked for a week, even with the evse attached
Yeah it’s weird that they didn’t include something to also charge the 12v while the car is connected
whaaat? why, was it set up on a charging schedule or something?
