So, I stripped a Model S 75D and the shell is gone. The battery pack was around 30% when I removed it from the car. I have the charge port, all the HV cables, and the onboard charger, battery pack, etc.

Is it possible to charge it while it's sitting there not yet ready to go into the conversion car? Should I even bother, or is it fine to sit for a few months at 30%? If it's even possible, what will it take to charge it? It can't be as simple as just plug it all in, right? I'm assuming it's going to be angry that it's not connected to the main head unit anymore; that seemed to be the brains of the entire operation.

you would need a method to control the battery contactors, and a way of controlling the charger itself.

I would imagine its fine sitting at 30%, so long as the BMS boards arent sitting active the whole time.

Well I'll ultimately need to charge it anyways, once it's in the car, so what would that be? The VCU? I'll admit I'm still not totally clear on the details of what is controlled by what, exactly.

The Tesla charger can be controlled by using this board: https://evbmw.com/index.php/evbmw-webshop/tesla-boards (more info: https://openinverter.org/wiki/Tesla_Mod ... N2_Charger). There is also a Gen3 charger that needs a different control board. https://openinverter.org/wiki/Tesla_Mod ... N3_Charger

Make sure to pick the right one.
