A battery pack housing and a battery pack

Abstract

This utility model provides a battery pack housing and a battery pack, relating to the field of batteries. The battery pack housing includes a shell body, an explosion-proof valve, and an explosion-proof valve protective film. The shell body has a first sidewall, on which the explosion-proof valve is disposed. A buffer reinforcement structure is provided at the mating point between the first sidewall and the explosion-proof valve. The explosion-proof valve protective film is located on the side of the explosion-proof valve facing inwards from the shell body. By providing a buffer reinforcement structure, the stress generated by the adjacent battery pack or the electrode core within the battery pack housing on the explosion-proof valve due to extrusion, impact, vibration, and other operating conditions can be effectively absorbed, preventing damage to the explosion-proof valve, which could lead to valve failure or battery pack leakage. In addition, the explosion-proof valve protective film on the side of the explosion-proof valve facing inwards from the shell body effectively prevents charged particles from ionizing to the explosion-proof valve and causing corrosion, and also prevents internal structures such as the electrode core from causing extrusion damage to the explosion-proof valve, thereby preventing valve failure or battery pack leakage.
