The invention relates to the technical field of batteries, particularly provides a battery pack box body, a battery pack and a vehicle, and aims to solve the technical problems that in the prior art, as the space reserved for an exhaust channel is smaller and smaller under the trend that the energy density of the battery pack is continuously improved, the positions for installing anti-explosion valves on the side wall and an upper cover of the box body are smaller and smaller, and the cost is reduced. Therefore, the installation position of the explosion-proof valve is difficult to arrange. In order to achieve the purpose, the battery pack box comprises a heat management component and an anti-explosion valve, the anti-explosion valve penetrates through a bottom protection plate and the heat management component, the anti-explosion valve is detachably and fixedly connected with the heat management component, and the interior of the box above the heat management component can be communicated with the outside when the anti-explosion valve is opened. The explosion-proof valves are integrated on the heat management component, the number of the explosion-proof valves installed on the side wall and the upper cover of the box body is reduced, the problem that the positions of the explosion-proof valves are difficult to arrange under the condition that the energy density of the battery pack is continuously improved is solved, the explosion-proof valves and the heat management component can be detached, and the explosion-proof valves are convenient to replace.
本发明涉及电池技术领域,具体提供一种电池包箱体、电池包及车辆,旨在解决现有技术中随着在电池包能量密度不断提高的趋势下,留给排气通道的空间越来越少,导致箱体侧壁和上盖上安装防爆阀的位置越来越少,从而引起防爆阀安装位置难以布置的问题。为此目的,本发明的电池包箱体包括热管理部件和防爆阀,防爆阀贯穿底护板和热管理部件,防爆阀与热管理部件可拆卸固定连接,热管理部件上方的箱体内部能够与外界在防爆阀打开时连通。本发明将防爆阀集成在热管理部件上,减少了防爆阀安装在箱体侧壁和上盖的数量,解决了在电池包能量密度不断提高的情况下防爆阀位置难以布置的问题,并且防爆阀与热管理部件之间可以拆卸,便于更换防爆阀。
