Hello all,
apparently, when charging Model 3 LR from 3phases, it can only charge with 11 kW (230V x 16A x 3). But, when it is being charged through UMC, it can take up to 7 kW (230V x 32A x 1). What I know about the onboard charger on Model 3 (
), it consists of three identical AC to DC converters. I assume only one is used when charging from 1phase. This would mean, when charging from 1phase, single converter is allowed to draw 32 amps, but when charging from 3phase, it is only allowed to draw 16 amps.
I see only two possible reasons why. Either there is really some limit, possible due to thermal losses, that if all three converters would draw 32 amps at the same time, the charger would overheat. Or the other more likely reason, that it is just a limit set in software?
Does anybody know the answer?
Thanks
