I can see IGBT s quite powerfull. You would have to dissassemble the PCBs to see which is it and to try if it is good.
However driver is VLA500 or similar advanced industrial driver it should only need 15V PSU and i think it is the black brick on the left of amp sensors.
Well if you have thermal fuse than that would shut driver down, but it would repower when event passes?
I would suggest ou take IGBT off and check it according to this
You can send me PM with your mail to continue this separately since this is BMS thread...
