Abstract

The invention discloses a battery module and a battery pack, and relates to the technical field of batteries. The battery module comprises an end plate assembly and a side plate assembly made of a material different from that of the end plate assembly. The end plate assembly comprises a fixed end plate and a transition connecting frame which are connected with each other; the transition connectingframe is connected to the end of the side plate assembly; and a connecting strap is arranged on the outer surface of the side plate assembly and connected with the transition connecting frame so as to prevent the side plate assembly from expanding. According to the battery module, the end plate assemblies and the side plate assemblies which are made of different materials are adopted; the connecting bridles are arranged to improve the structural strength of the battery module; the structural reliability is improved; machining and manufacturing are easy; and the cost is low.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a battery module and a battery pack. Background technique [0002] Each battery module includes a single battery and end plates and side plates for fixing the single battery. In the prior art, most of the end plates and side plates are made of the same material, which is not strong enough, and the battery is easy to expand after a period of use, which makes the entire battery module deformed and the structure unstable. Contents of the invention [0003] The objectives of the present invention include, for example, to provide a battery module and a battery pack, which can enhance the structural strength of the battery module, prevent deformation of the module, and make the structure more stable. [0004] Embodiments of the present invention can be realized like this: [0005] In the first aspect, an embodiment of the present invention provides a battery module, which include...
