AI Technical Summary
In the existing technology, the exhaust channel is located on the top cover of the battery pack, which has high airtightness requirements, resulting in complex assembly and the need to add sealing components to ensure airtightness.
Design an energy storage battery pack with cell exhaust channels arranged along the arrangement direction of the individual cells, sealed around the perimeter and sealed to the cell explosion-proof valve, spanning the crossbeam and fixed by fasteners, and an extension at the bottom to enhance sealing, which is connected to the exhaust duct outside the housing. The battery pack explosion-proof valve is connected to the exhaust duct to promptly discharge thermal runaway gas.
It simplifies the battery pack assembly process, improves sealing, reduces reliance on seals, prevents thermal runaway gases from accumulating inside the casing, and reduces the risk of combustion or explosion.
