Abstract

The invention provides a battery module and a confluence member and a confluence assembly thereof. The confluence member includes a first connecting portion, a second connecting portion, and a first main body portion. The first connecting portion is configured to be connected to a first battery of the battery module, and the second connecting portion is configured to be connected to a second battery of the battery module. The first main body portion is connected with the first connecting portion and the second connecting portion, and the first connecting portion and the second connecting portion are located on the same side of the first main body portion in the transverse direction. The first connecting portion and the second connecting portion are longitudinally arranged at intervals, anda first gap is formed between the two connecting portions. The first main body portion is provided with a first gap which is communicated with the first gap. The confluence assembly comprises the confluence member. The battery module comprises the confluence assembly and a plurality of batteries.

Description

technical field [0001] The invention relates to the field of batteries, in particular to a battery module, a confluence component and a confluence assembly thereof. Background technique [0002] A battery module generally includes a plurality of batteries and a busbar, and the busbar is connected to the plurality of batteries to realize the electrical connection of the plurality of batteries. However, in the existing battery module, the confluence member generally includes a connecting portion and a main body, the connecting portions are arranged at intervals, and each connecting portion is connected to the battery; the main body connects the connecting portions. The battery will expand during use, causing the connecting part to receive tensile stress; the tensile stress will be concentrated at the connection between the connecting part and the main body, which will easily cause the current confluence member to crack at the connection and affect the performance of the conflu...
