ENERGY-STORAGE FIRE FIGHTING METHOD AND SYSTEM, AND BATTERY MANAGEMENT SYSTEM AND STORAGE MEDIUM

Disclosed in the embodiments of the present application are an energy-storage fire fighting method and system, and a battery management system (BMS) and a storage medium. The method comprises: when a preset gas is detected by a first gas detector provided in a first battery module, a BMS starting a first exhaust fan corresponding to a first battery cluster where the first battery module is located, such that the preset gas is discharged from an energy-storage container; by means of the first gas detector and a second gas detector adjacent to the first gas detector, the BMS acquiring the concentration of the preset gas at each moment within a preset time period; by means of a first temperature sensor provided in the first battery module, the BMS acquiring the temperature of the first battery module at each moment within the preset time period; on the basis of the concentration of the preset gas at each moment within the preset time period and the temperature of the first battery module at each moment within th
