I'm buying a Leaf battery pack from a junk yard. I'm going to connect it 32s3p instead of 96s1p, to get ~120V nominal. I would save some money if I could use the original BMS with the new battery config, instead of buying an aftermarket BMS. Do you think that would work?
Will the BMS auto-balance cells when needed? or is that decision made somewhere else in the car, and sent to the BMS over the CAN interface?
In other words, do I need to write some code which reads the BMS through CAN, and sends commands to activate the shunts when appropriate? or will the BMS brain do that for me, so that just a simple monitoring app like Leaf spy would be needed?
EDIT: another thought, would it be beneficial to connect all ASICs (3 paralleled ASICs per cell group) to the reconfigured battery, so that the BMS "thinks" that "everything is fine, all 96 cells connected"? Or wouldn't that matter, BMS would work fine even if 64 cells are "dead"?
