Yes of course. 90 A at 450 V is only half maximum power for the traction battery. But the DC-DC is capable of charging the 12 V battery at ≈90 A. Headlights plus brake lights if the car is not in ready mode could come to at least 55+23 x 2 = 156 W ≅ 13 A, then add up to 100 W for the blower flat out, perhaps a high powered audio amplifier...Ah Humm this is the 12v battery supplying power to the electronics not the HV Drive Train battery
I wonder if the idea of the momentary push-button is to use the battery for just a second or three to get things started, then the DC-DC can take over. But then it would make more sense to let the DC-DC charge the 12 V battery. Even if you're just driving the car off the ship onto a car carrier, or carrier to storage.
So @Mgzs ev, where's the photos after you took it apart?
