METHOD AND SYSTEM FOR ALLOCATING IDENTIFIERS FOR MULTIPLE SLAVES OF A BATTERY PACK

摘要

The present invention relates to a method and system for allocating identifiers for multiple slaves of a battery pack. According to the present invention, a method in which a master battery management system (BMS) allocates identifiers for N (N being an integer greater than or equal to two) number of slave BMSs through a communication network comprises the steps of: (a) each slave BMS combining digital voltage measurement values of battery cells contained in battery modules managed by said each slave BMS so as to generate initial identifiers, and transmitting the initial identifiers to the master BMS; and (b) the master BMS re-allocating identifiers on the basis of the initial identifiers received from each slave BMS, and transmitting the allocated identifiers to each slave BMS. According to the present invention, identifiers can be allocated without pre-inputted identifiers for multi-slave BMSs and without a separate hardware configuration.
