Abstract
A method for diagnosing a control system for a stacked battery is disclosed. The control system comprises a plurality of processors, a plurality of controllers, and a monitoring unit (control unit). The method comprises sending a diagnostic information from the central unit to a top processor of the plurality of processors, transmitting a return information from the top processor of the plurality of processors to the central unit, comparing the diagnostic information sent from the central unit with the return information received by the central unit, and indicating a communication problem if the diagnostic information sent from the central unit is different from the return information received by the central unit. The steps are repeated by eliminating the top processor from a previous cycle and assigning a new top processor if there is no problem with the reconfigurable communication system.
