ABSTRACT:
A method for controlling and addressing a battery power source device having a plurality of battery pack systems connected in parallel or serially in parallel, each battery pack system having a battery pack block and a battery ECU connected thereto, is provided. The battery ECUs are connected to each other over communication lines, and a plurality of address setting terminals and address lines are connected to each other differently to provide a unique address to each battery ECU. When an abnormal state is detected in one of the battery pack blocks over the communication line, control is provided to the abnormal one of the battery pack blocks, identified by its address, to turn off its open/close relay contact to disconnect it from the parallel or the serial parallel connection, thereby preventing the function of the entire battery power source device from being stopped or degraded.
