When I did the jump start tests it seemed like it was drawing about 20 amps or so from the 12V battery for about 7 or 8 minutes. I think the jump start converter won't charge much when the HV battery is above about 330V or so. And the jump start only works when the car is off, which I finally realized is why the SoC doesn't change. The battery computer isn't on and doesn't know the battery is being charged. When I did the jump starts with the SoC around 46%, the HV battery voltage only went up a few volts and probably not much power went into the battery. Using the jump start when the HV battery already is above 40% is probably just a waste of time, but I guess it's possible that it could help a little.

No plans of tapping the HV lines. I don't have a 350 v dc/dc converter to force amps into that pipe either.
I was hoping that some point in the cycle was a step up converter, and tap the line before it...
Anyway, I was doing some research. I realized the AC/DC inverter is also in the battery pack. Can a mini grid tie inverter, one that is 600 watts and needs to be plugged into an outlet to deliver the charge, can that be used to send a charge to the 330v battery pack, forcing the current backwards through the ac/dc inverter and effectively charge the battery through the 110v in dash outlet? Is this something anyone has tried yet?
