AC & DC are NOT compatible, do that and a Huge Cloud of Magic Smoke will appear

Onboard charger is switching mode supply, with PFC it is dc native, but it may not start if control electronics not detect AC, most appliances with such supplies work on dc in specified voltage range, but some of them simply not start, nothing happens.
