Abstract

The invention relates to the field of batteries, provides a busbar connecting structure, a module, a battery pack and a vehicle. The busbar connecting structure comprises a first busbar, a second busbar and a connecting part, wherein the first busbar and the second busbar are arranged adjacently, and the connecting part is electrically connected with the first busbar and the second busbar. The connecting part is connected with the first busbar and the second busbar at the same horizontal height, and the connecting part is a flexible piece and extends in the horizontal plane where the horizontal height is located. According to the busbar connecting structure, the connecting part is a flexible piece and can adapt to the distance change between the first busbar and the second busbar to stretch and retract when a battery cell expands and contracts, so that the battery cell is prevented from being subjected to shearing force. In addition, the connecting part extends in the horizontal plane,the space between the first busbar and the second busbar is fully utilized, no extra space is occupied, and compact design of a module and abattery pack is facilitated.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a bus bar connection structure, a module, a battery pack and a vehicle. Background technique [0002] With the rapid development of new energy vehicles, the importance of power battery packs has become increasingly prominent. In the power battery pack, a reasonable component layout is very important. Within a certain space, the component layout should be as space-saving as possible. During the charging and discharging process, the cells of the power battery pack will expand and contract. As the number of cycles of the cells increases, the cells will gradually swell, causing the distance between the cells to change. The distance between the busbars connecting different batteries will also change accordingly, and if the connectors between the busbars cannot adapt to this change, it will exert force on the busbars and cause the poles of the batteries to be sheared. cut force. ...
