I have a hybrid whose traction battery has become completely discharged, meaning it will no longer start the ICE. The repair process is to remove the hybrid battery, open it up, and apply high voltage DC to charge it up.
I’ve got it opened up, now I need 350 volts of DC.

I have a level 1 charger that came with my electric car, can I ‘trick’ it into producing supply? When it’s plugged in, the output is zero, so obviously it needs some kind of signal to start charging. Anyone know how that works or where it’s documented?

Many thanks.
