When overpressure occurs, the pressure relief valve 5 can respond quickly and automatically open the pressure relief channel to safely discharge excess gas and the like to the external environment, thereby preventing the internal pressure from being too high and ensuring safe operation. In addition, arranging the pressure relief valve 5 can help ensure the fire extinguishing effect. When a fire occurs inside the energy storage box, fire extinguishing agents may be sprayed for fire extinguishing. If the internal pressure is too high, it will affect the spraying effect of the fire extinguishing agents. By opening the pressure relief valve 5, the internal pressure of the system can be balanced to ensure that the fire extinguishing agents can be sprayed smoothly and evenly onto the fire area, improving the fire extinguishing efficiency. In practical applications, the pressure relief valve 5 can be used to prevent the air pressure released instantaneously when the battery fails.
