METHOD AND SYSTEM FOR ALLOCATING IDENTIFIERS TO MULTI-SLAVE IN BATTERY PACK
First Claim
1. A 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, the method comprising:
- (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.

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.

8. A system for allocating identifiers, comprising:
-
N number of slave BMSs, each of which generates an initial identifier by combining digital voltage measurement values of battery cells included in a battery module managed by the slave BMS and transmits the initial identifier to a master BMS through a communication network; and a master BMS for allocating identifiers again according to the initial identifier received from each slave BMS and then transmitting the identifiers to the slave BMSs through the communication network. - View Dependent Claims (9, 10, 11, 12, 13, 14)
