[0002] Energy storage technology is an important means to meet the large-scale intervention of renewable energy, and is also an important component of distributed energy systems and the electric vehicle industry. Energy storage batteries have the advantages of high efficiency, good dynamic characteristics, long service life, and are almost unaffected by terrain. They are widely used in energy storage power stations, battery swap stations and other scenarios.
[0003] Due to the activity of the energy storage battery electrodes and the instability of the electrolyte, during use, if the external circuit of the energy storage battery is short-circuited; the internal materials of the energy storage battery are short-circuited; overcharging; the energy storage battery is hit, squeezed, and mechanically damaged, the energy storage battery will be triggered to have thermal runaway, and the chemical reaction between its internal materials will release heat, causing fire or explosion accidents. It is necessary to set up a fire-fighting device that matches the energy storage battery. However, the existing fire-fighting devices are generally unable to cool the energy storage battery. Therefore, we propose an energy storage battery fire-fighting device with automatic cooling function. Utility Model Content
