The invention provides a battery pack box body and a battery pack and belongs to the field of lithium ion batteries. A battery box body is included, the battery box body is internally provided with aplurality of independent cavities for installing batteries, a side surface of the battery box body is provided with a liquid cooling inlet and a liquid cooling outlet, and the liquid cooling inlet andthe liquid cooling outlet are connected through a liquid cooling flow channel arranged in the battery box body so as to cool an inner portion of the battery box body; a groove is arranged between every two adjacent cavities and serves as an electric connection reserved space between battery packs; and an exhaust passage is arranged in the battery box body, the exhaust passage is connected with the cavity, and an explosion-proof valve is arranged at an exhaust end of the exhaust passage. In the invention, structural components of a battery module level are cancelled, a battery pack system is directly constructed from a battery cell level, a process is simpler, and a battery grouping rate can be increased to above 80%.

    本发明提供了一种电池包箱体及电池包,属于锂离子电池领域,包括电池箱体,所述电池箱体的内部设有多个独立的安装电池的腔体,所述电池箱体的侧面设有液冷进口和液冷出口,所述液冷进口和液冷出口通过设置在所述电池箱体内的液冷流道连通设置,对所述电池箱体的内部进行降温;相邻的腔体之间设有凹槽,作为电池组之间的电连接预留空间;所述电池箱体的内部设有排气通道,所述排气通道与所述腔体连通设置,所述排气通道的排出端设有防爆阀。本发明取消了电池模组层级的结构部件,实现了从电芯层级直接构建电池包系统,工艺更简单化,电池成组率可提升至80%以上。
