It is destined to become the most important flexible resource in the future. Energy storage battery packs are consumables; therefore, the sealing of the battery installation must be considered during use to avoid the influence of external factors. A search of application CN202322381912.5 discloses an energy storage battery pack structure, which includes a battery pack housing and a cover for the housing. The battery pack housing has an open top, and the top cover is fitted with a box...
