Abstract

The invention discloses a battery module, a battery pack and a vehicle. The battery module comprises a laminated body, the laminated body comprises a plurality of stacking bodies, and each stacking body is formed by stacking a plurality of soft package battery cells; in one stacking body, the positive and negative tabs of each soft package battery cell are respectively connected to form a positiveand negative connecting part, and the stacking body is connected in series with the negative connecting part / positive connecting part of another stacking body adjacent to the stacking body through the positive connecting part / negative connecting part; an end holder provided on the positive electrode connection portion or the negative electrode connection portion of the stacked body at both ends;and an intermediate bracket provided between two adjacent stacking bodies. The single soft package battery cells in the battery module are connected in parallel, and the series tabs are directly connected, so that the cascade connection among the stacked body modules is realized. Series-parallel copper bars and external installation structures are reduced, module group accessories are reduced, thecost and the weight are reduced, and the space utilization rate is increased.

Description

technical field

[0001] The present invention relates to the field of new energy vehicles, in particular, the present invention relates to battery modules, battery packs and vehicles. Background technique

[0002] With the continuous popularization of new energy vehicles, the requirements for the use of power batteries in new energy vehicles are becoming higher and higher. In particular, users' requirements for the continuation mileage of new energy vehicles are constantly increasing. For common new energy vehicles, the power battery pack exceeds 1m in both length and width; while currently on the market, the length of the battery module is generally about 0.3m. Therefore, in the power battery pack, at least three or even more battery modules need to be installed.

[0003] If multiple battery modules are installed, it is necessary to add a fixing structure to each battery module, and the assembly is complicated. At the same time, the power connection between two adjacent ba...
