Wireless Battery Management System and Method for Protecting Battery Pack Using Same

Disclosed are a wireless battery management system and a method for protecting a battery pack using the same. The battery pack includes a plurality of battery modules and at least one relay. The wireless battery management system includes a plurality of slave controllers electrically coupled to the plurality of battery modules one-to-one, and a master controller wirelessly coupled to each slave controller so as to be able to communicate with each slave controller. Each slave controller measures an operational parameter of the battery module electrically coupled thereto. Each slave controller wirelessly transmits a fault signal to the master controller when the measured operational parameter is outside of a predetermined normal range. The master controller turns off the at least one relay when the fault signal is received.
