  • Patent number: 8963507
    Abstract: Disclosed is a method and system for allocating identifiers to multi-slaves in a battery pack. The method for allocating identifiers, in which a master battery management system (BMS) allocates identifiers to N (N is an integer of 2 or above) number of slave BMSs through a communication network, includes (a) by each slave BMS, generating an initial identifier by combining digital voltage measurement values of battery cells included in a battery module managed by the slave BMS and transmitting the initial identifier to a master BMS; and (b) by the master BMS, allocating identifiers again according to the initial identifier received from each slave BMS and then transmitting the identifiers to slave BMSs. Therefore, it is possible to allocate identifiers without inputting an identifier to a multi-slave BMS in advance or using a separate hardware configuration.
