Abstract: A firefighting method and system for energy storage, 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 determines whether to turn on a first firefighting apparatus corresponding to the first battery cluster based on a concentration of the preset gas at each moment in a preset period and a 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.

Abstract: A linkage control system and a linkage control method for battery clusters are provided in the disclosure. In the system, when thermal runaway occurs in a certain battery cluster, in the condition that an inhibitor in an isolation-and-suppression device in the battery cluster is in a normal state, the control host can suppress thermal runaway of the battery cluster by the inhibitor in the isolation-and-suppression device. In the condition that the inhibitor in the isolation-and-suppression device is in an abnormal state, the control host can determine, from adjacent battery clusters, a battery cluster capable of supporting an inhibitor, to solve thermal runaway by the inhibitor in the isolation-and-suppression device in the battery cluster.
