A Battery (Battery) refers to a device that converts chemical energy into electrical energy in a cup, tank, or other container or portion of a space of a composite container that contains an electrolyte solution and metal electrodes to generate an electrical current. Although the power safety operation level of China is globally leading, no overlarge power failure event occurs, and the coverage rate of a power distribution network of China is more than ninety percent, the power failure phenomenon and the remote area without power supply still occur in partial areas. Therefore, in some households or markets, a rack-mounted household energy storage battery may be used as a backup power source for the household or market.
The frame-type household energy storage battery is formed by integrating a lithium battery module, an energy storage converter and the like into a cabinet body, and the internal circuit connection is completed only by using a finished integrated cabinet. When the rack-mounted household energy storage battery is installed and used, the rack-mounted household energy storage battery can be put into use only by connecting two groups of power cables for charging and discharging. Because the coverage rate of the power distribution network in China is high and the power failure rate is low, the using frequency of the rack-mounted household energy storage battery is too low, and in order to increase the utilization rate of the rack-mounted household energy storage battery, the rack-mounted household energy storage battery with sufficient electric quantity can be used for electricity consumption in suburb travel and outdoor activities.
However, all cabinets of the existing rack-mounted household energy storage battery are inconvenient to move, chemical reaction can occur in the lithium battery during discharging, a large amount of heat energy is generated, the lithium battery is heated after being charged in an overload manner, the heat of the battery can be increased after the battery is heated for a long time, if the sealed battery can lead the air in the battery to expand severely, the battery protrudes outwards, the battery can be seriously exploded, and the existing rack-mounted household energy storage battery cannot timely dissipate the heat of the lithium battery and is used for avoiding explosion and ignition of the lithium battery.
