[0003] Most existing energy storage power supplies that can power high-power electrical appliances include a box with a high-power battery pack installed in it. The battery pack is electrically connected to the socket on the box. The box is provided with an air inlet, and a fan draws external cold air into the box to dissipate heat for the battery pack in the box. When the energy storage power supply is powering high-power electrical appliances, the cold air can reduce the operating temperature of the battery pack.
