[0002] Electrochemical energy storage cabinet is a widely used integrated energy storage system, which converts electrical energy into chemical energy for storage through chemical reaction and releases it back to the power system when needed. They are used in various aspects of power generation, transmission, distribution and electricity consumption of power systems. The main features include small influence from geographical factors, flexible application scenarios, short construction period, fast response speed, relatively mature technology, high energy density and high conversion efficiency. However, the fire safety of electrochemical energy storage cabinet is an important consideration. Lithium-ion batteries, as the main component of electrochemical energy storage cabinet, have the risk of thermal runaway, which may cause fire or explosion. Therefore, it is necessary to configure a fire control system for electrochemical energy storage cabinet. The fire of lithium-ion battery energy storage system is characterized by intense burning, rapid heat spread, strong toxicity, large smoke, easy rekindling and difficult to extinguish. It is different from traditional buildings or other types of fires. Usually, multiple different fire detection devices are configured in energy storage power stations. After a fire occurs, fire blocking and fire control measures are often completed by multiple different fire extinguishing devices. Due to the compact structure of electrochemical energy storage cabinet, the capacity of internal batteries, battery pack arrangement and battery storage compartment size are different, and the size and release method of the configured fire extinguishing devices are also different. Therefore, traditional fire control controllers are difficult to meet the requirements, and a special high-efficiency fire control system with high integration and compact structure needs to be designed.

The signal input module receives input signals through a signal input interface. The power module receives input power through a power interface. The communication module receives data transmission through a communication interface. The display module connects communication indicator lights and power indicator lights for status display. The drive module connects multiple multifunctional drive interfaces, and the output of each drive interface is configured as different voltage and current drive signals to drive various fire extinguishing devices, sound and light alarms and other fire control system devices. This scheme sets all terminal plug-in openings on the same side of the shell, which has the problems of limited number of external ports, too dense external connection lines and inability to reduce the size of the controller. This also limits the number of external communication and control interface lines and the function expansion of the controller. SUMMARY
