Abstract
A method of identifying a non-communicative battery Cell Sensing Board (CSB) within a plurality of battery CSBs arranged in a serial chain includes sequentially reconfiguring the serial chain of the battery CSBs to sequentially define each of the plurality of battery CSBs as a last battery CSB in a temporary test serial chain. Communication with the last battery CSB of each temporary test serial chain is sequentially established with a loopback feature of the battery CSBs. When a disruption in communication between the battery system manager controller and the last battery CSB of the current temporary test serial chain is detected, the last battery CSB of the current temporary test serial chain is identified as the non-communicative battery CSB.
