Problems solved by technology

In addition, due to the presence of multiple cells in the battery module, the heights of the multiple cells (the top faces of the poles) cannot be completely consistent in practice; however, the conductive sheet (aluminum bar) is separated by the The plane is limited to the same height, so there may be a gap between the pole of the battery with a lower height and the conductive sheet (aluminum bar), resulting in poor welding between the pole of the battery and the conductive sheet (such as virtual welding) or welding is prone to failure

Abstract

The invention provides a battery module. The battery module comprises a wire harness isolation plate integration module which is integrally and horizontally arranged above a plurality of battery cells of the battery module. According to the wire harness isolation plate integration module, the conducting strip group and the isolation plate are integrated into an integral structure, and the two side edge parts of each isolation unit are respectively provided with at least one elastic part, so that in specific application practice, if a battery cell expands, the elastic parts of the two side edge parts of the isolation unit generate elastic deformation, therefore, the pulling force generated by the expansion of the battery cell is absorbed, and the separation plate is prevented from being broken; in addition, the problem of poor welding between the low-height battery cell pole and the conducting strip caused by inconsistent heights of the battery cells can be well solved.

Description

technical field [0001] The invention relates to an integrated battery module and belongs to the technical field of batteries. Background technique [0002] The battery module is the smallest unit of a new energy power supply system, which generally includes a battery cell, a conductive sheet (such as an aluminum bar), a wiring harness board or a flexible circuit board (FPC) for low-voltage sampling, a wiring harness isolation board, and a module Components such as end plates, module side plates and module cover plates. [0003] Among them, a battery module contains a plurality of batteries, and a conductive sheet (aluminum bar) is welded to the top surface of the pole of each battery, and the electrical connection between the conductive sheets realizes the series or parallel connection between the batteries. . The wire harness isolation board is used to isolate the battery cell and its conductive sheet from the wire harness board or FPC used for low-voltage sampling. Such ...
