WIPO Patent Application WO/2024/034879

A1

The present invention relates to a method of predicting the occurrence of battery fire and a battery system providing same. The battery system of the present invention comprises: a battery module including multiple battery cells; a slave battery management system (BMS) which performs a first low power mode for waking up every first period and determining whether a first fire event of the battery module has occurred, and a second low power mode for, when the battery module is determined as being in a stable state according to predetermined safety standard, waking up every second period longer than the first period by a predetermined interval and determining whether the first fire event has occurred; and a master BMS which, while the battery module is not supplying power to an external device, transfers a first control signal indicating to enter the first lower power mode to the slave BMS, and then enters a sleep mode.
