1. A battery identification (ID) setting system comprising:
- a master battery management system (BMS) for outputting an ID setting signal; and
a plurality of slave BMSs for transmitting battery information signals containing absolute battery IDs and battery potential differences of batteries to the master BMS in response to receiving the ID setting signal,wherein the master BMS is configured to receive the battery information signals, to assign and store relative battery IDs corresponding to the absolute battery IDs of the batteries based on the battery potential differences, and to transmit relative battery ID signals containing the relative battery IDs assigned by the master BMS.

Abstract
A battery identification (ID) setting system effectively managing a plurality of batteries and a method of driving the same. The battery ID setting system having an external terminal includes a master battery management system (BMS) outputting ID setting signals, and a plurality of slave BMSs transmitting battery information signals containing absolute battery IDs and battery potential differences of batteries to the master BMS in response to the ID setting signals. The master BMS receives the battery information signals to assign and store the relative battery IDs corresponding to the absolute battery IDs of the batteries.

12. A method of driving a battery ID setting system comprising a master battery management system (BMS) and a plurality of slave BMSs, the master BMS performing:
-
transmitting an ID setting signal to the slave BMSs; receiving battery information signals containing absolute battery IDs and battery potential differences of batteries transmitted from the slave BMSs in response to the ID setting signal; selecting one of the battery information signals based on the battery potential differences received from the slave BMSs; assigning one of relative battery IDs corresponding to a respective one of the absolute battery IDs from the selected one of the battery information signals and storing the assigned one of the relative battery IDs when the selected one of the battery information signals is received; and transmitting relative battery ID signals containing respective ones of the relative battery IDs assigned by the master BMS to corresponding ones of the slave BMSs. - View Dependent Claims (13, 14, 15, 16)
