Background With the rapid development of new energy industry, distributed energy storage systems (such as container type energy storage and household energy storage) are widely used. Electrochemical energy storage cells, particularly lithium ion cells, present a thermal runaway risk in the event of operation or anomalies, which can cause fires and even explosions, and therefore efficient and reliable fire protection systems are critical to the safe operation of the energy storage system. Currently, fire alarms and fire initiation of energy storage systems typically rely on complex electronic control systems. The system is generally composed of a smoke sensor, a temperature sensor, a gas detector and other detectors, a main controller and a fire extinguishing device. The working flow is that various sensors monitor environmental signals in real time and transmit the environmental signals to a main controller, the main controller analyzes and judges the signals based on a preset algorithm, and after fire is confirmed, an instruction is sent out to start the fire extinguishing device.
