Abstract: Provided are a control method for an energy storage system and the energy storage system. The energy storage system includes N energy storage sub-modules, where N is a positive integer greater than 1. The control method for the energy storage system includes: acquiring an SOC and a charge-discharge limiting current of each of the N energy storage sub-modules; and controlling working states of the N energy storage sub-modules according to the SOC and the charge-discharge limiting current of each of the energy storage sub-modules, where the working states include a switched-on state and a switched-off state. According to the technical solution provided by embodiments of this application, the problem of SOC imbalance among the energy storage sub-modules can be solved, so that the utilization rate of the energy storage system is improved.

Abstract: Embodiments of this application provide a fire-fighting switch device and a fire-fighting system, which are applied to the field of fire-fighting. The fire-fighting switch device includes a plurality of fire detection switch units, where the fire detection switch unit includes one or more fire detection switches, the one or more fire detection switches form at least one switch path, the fire detection switch is configured to turn on when a fire is detected, and any one of the switch paths is configured to transmit a voltage signal to a fire-extinguishing device when all of the fire detection switches on the switch path are turned on. In this solution, when a fire is detected by one fire detection switch unit, the fire-extinguishing device can be controlled to extinguish the fire provided that all fire detection switches on one switch path in the fire detection switch unit are turned on.
