The invention relates to a fixing band for a battery module and the battery module. The fixing band includes a first end, a connecting part and a second end that are successively distributed along its own extension direction, and the first end includes a body and a The occlusal groove protrudes along the thickness direction of the body, the occlusal groove and the body are integrally formed, the second end has an occlusal protrusion matching the shape of the occlusal groove, and the first end and the second end can be stacked in the thickness direction And through the occlusal groove and the occlusal protrusions occlusal with each other, so that the fixing band encloses and forms an annular accommodation space. The fixing strap provided by the embodiment of the present invention can be used to fasten the single battery group and the end plate to resist the expansion force of each single battery, and the joint position structure of the closed loop formed by the fixing strap is simple, easy to overlap and connect It has high strength and meets the requirements of battery modules.
Description
Technical field [0001] The present invention relates to the technical field of batteries, in particular to a fixing belt for battery modules and battery modules. Background technique [0002] The battery module in the traditional technology generally includes a single battery pack formed by stacking a plurality of single batteries and end plates arranged on both sides of the single battery pack. The end plates on both sides are respectively welded and fixed to the two side plates. Resist the expansion force from the single battery. [0003] With the gradual improvement of battery technology, the market’s requirements for battery modules have also been continuously improved, and gradually developed into a module-free structure. The said module-free structure has been cancelled compared to the battery module structure in the traditional technology. Connect the side plates of the two end plates. Due to the cancellation of the side plate, there is no connection between the side plate...
