In order to improve the sealing and waterproof performance of household energy storage battery systems, it is necessary to reasonably design the sealing structure of the battery box. However, during the use of most energy storage batteries, the protection mechanism only considers the waterproofness of the battery during use, but does not consider that when the battery is working in a closed environment for a long time, due to poor ventilation, it is easy to cause the temperature of the battery to be too high during operation. High temperature will accelerate the aging of electronic components in the battery box and shorten the service life of the energy storage battery. Utility Model Content
