QUOTE(brkli @ May 5 2025, 07:35 PM) actually, from engineering POV, still make sense to have this separate 12V battery for things like open/close door, e-brake, light and etc. that is provided it is working alongside a step down (to 12V) main EV battery. reason being, if one of the battery got damage, those critical component of the car (like e-brake, hazard light, ecu stuff) can still function. From engineering pov, what you wrote doesn't quite cut it unless there's redundancy factored in. If the 12V kaput, can those critical components still work? I know in ICE cars, the alternator can still supply power. |

QUOTE(Boy96 @ May 5 2025, 09:28 PM) Can. We've tried before, unplug the 12v on the ev , car still runs as usual So that explains why it's unlikely to be the fault of the 12V battery, just as you mentioned in another post. |

QUOTE(trusol @ May 6 2025, 05:53 PM) Those who have used ICE for a long time very likely to kena alternator kong at least once. But not as often as the 12v battery kong, which is like once every 2 to 3 years cannot start the car. In the past, alternator Kong resulted in stalled engine, which still allowed for some safety manoeuvre. Now it seems the car auto brakes suddenly. |

QUOTE(zerorating @ May 7 2025, 12:00 PM) auto brake because of regenerative braking kot. question is why the driving system depends on 12v battery? if the voltage is too low, it should at least prompt the user, complain charge system failure or some shit. takkan la takda voltage sensor on those low power system? Referring to the Vios. |
