Except they have a 12v solenoid to engage/disengage the drive voltage in the event of a crash, which is why if you leave your lights on you might need a 12v "jump" even if the drive battery is fully charged.
- Gravityloss 3y agoHmm does 48V really need to be disconnected? What's the reasoning? Honest question: is there something else than path dependence preventing just switching everything in a car from 12V to 48V? Even interior lighting? Ie is there some place where 12V is actually significantly better for physics reasons?
