AUTOMATIC ID ALLOCATION SYSTEM AND METHOD FOR BATTERY MODULE

The present invention is to automatically ID assignment of a battery module and includes: a batter module including: a pressure detection unit provided on a predetermined surface part of a battery module and configured to detect a pressure applied to the predetermined surface part and output a pressure value; a wireless communication unit configured to transmit a pressure detection signal including the pressure value to the upper-level BMS through wireless communication; and when ID information automatically assigned from the upper-level BMS is received, a first control unit configured to set and register the received ID information as its own ID and inserted into a battery module mounting part formed in at least one battery rack; and an upper-level BMS configured to wirelessly communicate with the battery module and including: a second control unit configured to identify a battery module that has transmitted a pressure detection signal including a pressure value, and automatically assign an ID to the identified battery module based on a reference pressure value corresponding to a battery module mounting part into which each of the battery modules are inserted; an ID information storage unit configured to store a reference pressure value for identifying the battery module and ID information that is automatically assigned in association with the reference pressure values; and an ID assignment information storage unit configured to store ID information that is automatically assigned to the battery module identified by the control unit.
