Abstract

The invention discloses a battery box. The battery box comprises a battery box body and multiple battery packs, wherein a main accommodating space which is sealed for blocking external gas is formed in the battery box body; a pressure-deformable part is arranged on the wall surface of the battery box body; one side of the pressure-deformable part is in pressure contact with the outside while the other side of the pressure-deformable part is in pressure contact with the main accommodating space; the multiple battery packs are accommodated in the main accommodating space; and after the multiple battery packs are electrically connected, the multiple battery packs extend out of the battery box body to form a positive electrode and a negative electrode. The battery box provided by the invention can adjust the pressure in the battery box and can achieve a technical effect of relieving fatigue aging.

Description

technical field [0001] The present application relates to a battery box, in particular to a sealed battery box in the field of electric vehicles. Background technique [0002] In the battery boxes used in existing new energy vehicles, since lithium batteries have non-negligible volume changes during charging and discharging, resulting in pressure changes in the box, waterproof and breathable valves are generally installed to alleviate the pressure changes in the box. [0003] see figure 1 As shown, the Chinese invention patent application whose publication number is 103311479A discloses a sealed battery box. This sealed battery box has main box body and loam cake 70, and waterproof breathable valve 72 is installed on the main box body, and waterproof breathable valve 72 has waterproof breathable film layer, guarantees the waterproofness of battery box. [0004] When sealing the battery box and taking into account the breathable and pressure-regulating function, although th...
