So, hilariously, my fancy new EV broke today. Wouldn’t turn on!! How?
Well, the good news is that the 40kWh main battery is fine.
But there’s also a regular 12v battery that powers…well…everything that’s not the motor. Locks, lights, sound, displays, electronics.
And it turns out that everything turns off when you open the drivers door. But this is NOT the case for the passenger door.
So the media display was left on, the 12v battery drained, and the car was dead.
