Abstract
Embodiments of the present invention are directed to a battery stack with a leapfrogging communication network. Each cell stage may include a controller, a transmitter, and a pair of receivers. The cell stage in the battery stack may be coupled to the closest two preceding battery cell stages in the stack. In this manner, each cell stage may be able to determine if a fault is present in an immediately preceding cell stage in the stack by monitoring the first preceding cell stage and the second preceding cell stage. If discharge/charge commands transmitted by the second preceding cell stage are not reaching the battery cell stage at issue, the controller may determine that there is a fault in the first preceding cell stage and discharge/charge the cell stage based on the commands transmitted by the second preceding cell stage.
