Abstract:
1. A system for allocating an identifier to a multi-battery management system (BMS) that allocates a unique communication identifier to a multi-BMS of a battery pack, the system comprising a master BMS and N slave BMSs (N is an integer greater than or equal to 2) connected to a serial communication network and a parallel communication network, wherein the master BMS includes at least two first and second master communication channels that form a communication interface with the serial communication network and selectively output a forward or backward wake-up signal, and allocates a unique communication identifier to the slave BMS through the parallel communication network, and the first through N th slave BMSs wake up in response to the forward or backward wake-up signal received through the series communication network, are allocated with the identifier from the master BMS through the parallel communication network, and output the wake-up signal to the adjacent slave BMS along the transmission direction of the wake-up signal.
