Abstract
A battery management system for a battery pack having a plurality of battery modules includes a master battery management system disposed in the battery pack and configured to transmit a wake-up signal, and slave battery management systems each configured to periodically check for the wake-up signal at a reception period and to transmit state information of a corresponding one of the battery modules to the master battery management system if the wake-up signal is received. A first slave battery management system, among the slave battery management systems, is configured to transmit a request signal to the master battery management system at a start of the reception period of the first slave battery management system. Based on the request signal, a second slave battery management system is configured to synchronize the reception period of the second slave battery management system with the reception period of the first slave battery management system.
