FIREFIGHTING METHOD AND SYSTEM FOR ENERGY STORAGE, BATTERY MANAGEMENT SYSTEM, AND STORAGE MEDIUM

A firefighting method and system for energy storage, a battery management system (BMS), and a storage medium are provided in implementations of the present disclosure. The method includes the following. The BMS turns on a first exhaust fan corresponding to a first battery cluster where a first battery module is disposed to exhaust a preset gas from the energy-storage container, when a first gas detector disposed in the first battery module detects the preset gas. The BMS obtains a concentration of the preset gas at each moment in a preset period through the first gas detector and a second gas detector adjacent to the first gas detector. The BMS obtains a temperature of the first battery module at each moment in the preset period through a first temperature sensor disposed in the first battery module. The BMS determines whether to turn on a first firefighting apparatus corresponding to the first battery cluster based on the concentration of the preset gas at each moment in the preset period and the temperature of the first battery module at each moment in the preset period, to extinguish a fire at a battery module in the energy-storage container.
