[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] Reference Figures 1 to 4 A side-fixed battery module includes a module body 10, an integrated busbar 2 and an upper cover 3, the integrated busbar 2 is provided with a plurality of grooves 201, and the upper cover 3 is provided with a plurality of blocks 301; the battery module also includes a connector 4 and a plurality of Z-shaped pressing plates 5, the connector 4 is arranged in a box for installing the module body 10, the connector 4 is provided with a plurality of slots 401, the integrated busbar 2 is arranged on the module body 10, the top bottom of the pressing plate 5 contacts the wall in the horizontal direction of the groove 201, the bottom end of the pressing plate 5 cooperates with the slot 401, the upper cover 3 is bolted to the integrated busbar 2, and the block 301 contacts one side of the top of the pressing plate 5. In the present utility model, the connector 4 is installed in the box where the module body 10 is placed. The module body 10 is placed in the box, the integrated busbar 2 is installed, and then the pressing plate 5 is installed. One end of the top of the pressing plate 5 cooperates with the groove 201, and one end of the bottom of the pressing plate 5 cooperates with the card slot 401, which effectively prevents the battery module from vibrating up and down during transportation, and improves the strength of the module fixed in the box. The stopper 301 contacts one side of the top of the pressing plate 5 to prevent the pressing plate 5 from moving in the horizontal direction. Specifically, the upper cover 3 is connected to the nut through the integrated busbar 2.
