Abstract

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.

Description

technical field [0001] The present disclosure relates to a method and system for setting an identifier for each slave BMS in a multi-slave battery management system (BMS) applied to a battery pack with a multi-cell structure, and more particularly relates to a A method and system for combinatorial assignment or assignment of identifiers of digital voltage measurements of battery cells contained in a battery module. [0002] This application claims priority from Korean Patent Application No. 10-2011-0089746 filed in Korea on Sep. 5, 2011, the disclosure of which is incorporated herein by reference. Background technique [0003] Secondary batteries have high applicability according to product categories and excellent electrical characteristics such as high energy density, and thus are generally used as power sources of electric vehicles (EV) or hybrid vehicles (HV) and mobile devices. These secondary batteries have the fundamental advantage of greatly reducing the use of foss...
