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.

    This is one of those situations where if you don’t immediately have an idea of how to do it, you probably shouldn’t even consider it. I’m all for DIY, but based on your question it seems you don’t have a base level of electrical and battery knowledge – to the point that of me to offer either specific advice or to even point you in the right direction.

    The EVSE is just an extension cord with extra parts. It has no way to convert AC to DC.

    Please close it up and let someone else handle this.

    Most hybrids have a 12V battery to start the ICE. You should only need to charge it with a regular car battery charger. Or replace it if it got old. You’re likely trying to solve the wrong problem. Check your 12V battery.

    Level 1 and 2 are AC power, so of course that does not work.

    Maybe you could tow charge it. Strap it to another car and just pull it with regen on. People do that with electric cars. I have not heard if that works with hybrid though.

    But really you should get it towed and repaired properly.
