METHOD AND APPARATUS FOR DETECTING THERMAL RUNAWAY OF BATTERY PACK

A method for detecting thermal runaway of a battery pack including at least one battery module in a master battery management system (BMS) is provided. The method for detecting thermal runaway includes: detecting a communication error with at least one slave BMS that detects information on the at least one battery module; if a communication error with the at least one BMS is detected, obtaining temperature of a master board from a temperature sensor located on the master board in which the master BMS is installed; and detecting thermal runaway of the battery pack using the temperature of the master board.
