A filter 12 is installed inside the exhaust vent 11. The heat dissipation fan 5 is started to accelerate the high-temperature air inside the energy storage box 1 to be discharged from the inside of the energy storage box 1, thereby improving the heat dissipation efficiency inside the energy storage box 1. Under the action of the filter 12, external dust and impurities are prevented from entering the inside of the energy storage box 1 through the exhaust vent 11.
