More Information
Summary:A busbar diagnosis apparatus according to an aspect of the present disclosure includes a plurality of voltage sensing pins, a battery monitoring circuit, a voltage sensing channel; a bypass unit and a control circuit to diagnose the busbar. According to an embodiment of the present disclosure, a voltage of each of a plurality of battery cells of a first battery module and a plurality of battery cells of a second battery module is detected using a potential difference of every two adjacent voltage sensing pins, and the busbar is diagnosed based on a voltage history of each of the plurality of battery cells.
