The invention discloses a battery pack for battery side liquid cooling. The battery pack comprises batteries arranged in a box body and vertically arranged liquid cooling plates. A plurality of battery separation structures are arranged on a bottom plate. The battery separation structure comprises a plurality of first separation plates vertically arranged on the bottom plate and a plurality of second separation plates vertically arranged on the bottom plate. The two adjacent first partition plates and the second partition plate between the two adjacent first partition plates form an H-shaped structure. The liquid cooling plates bridge the first partition plates of the battery partition structures. And the internal space of the box body is divided into a plurality of battery row channels bythe parallel liquid cooling plates. And the batteries are sequentially arranged in the battery row channels. And in the battery row channels, the adjacent batteries are separated by the second separation plates. Wire harness isolation plates are fixed with the liquid cooling plates and the first partition plates through bolts. Therefore, the batteries are fixed by the liquid cooling plates and the wire harness isolation plates, so that components for fixing the batteries are reduced, the utilization rate of the space in the battery box is improved, and the overall energy density is improved.
本发明公开了一种电池侧液冷的电池包,包括设置在箱体的电池和竖直设置的液冷板。底板上设置有若干电池分隔结构。电池分隔结构包括若干竖直设置在底板上的第一分隔板和若干竖直设置在底板上的第二分隔板。两块相邻的第一分隔板和之间的第二分隔板组成H形的结构。液冷板跨接各电池分隔结构的第一分隔板。相互平行的液冷板将箱体的内部空间分隔出若干电池排通道。电池按顺序依次排列在电池排通道内。电池排通道内,相邻电池之间通过第二分隔板相隔。线束隔离板通过螺栓与液冷板、第一分隔板相固定。由此,电池由液冷板和线束隔离板固定,从而减少了用以固定电池的构件,进而提高了电池箱箱内空间的利用率,提高了整体的能量密度。
