Hi, I have been searching for canbus protocol to talk to a CAN provisioned jbd bms. I have 9 batteries to connect and would prefer to monitor each directly using can bus ( instead of UART or rs485).
Could someone suggest where I may further search to find the correct ids ect to send for replies. Or assist with this info. Thankyou kindly
 
I have a not-so-dumb question. CANBUS is not galvonically isolated. So what happens to the ground reference when one of the BMS units decides to switch off on the ground side of the battery?
 
The ground reference is hard-wired into the battery pack. (the black 22 AWG wire)
It is not effected when the BMS decides to disconnect itself.
