AI Technical Summary

⚠Technical Problem

In existing technologies, stacking battery cells along their thickness direction leads to a rapid increase in the thickness of the battery module, making it difficult to meet the requirements of thin and light designs.

⚗Method used

The battery cells are arranged in a single layer along their width and length. The space of the bracket is used to limit the position of the battery cells by limiting components, so as to ensure that the sum of the thickness of the battery cells and the bracket is controlled within the range of 0mm to 1mm, thus avoiding the increase of thickness.

🎯Benefits of technology

It achieves a compact design for battery modules, meeting the capacity requirements of multiple cells while significantly reducing thickness, improving space utilization, adapting to the lightweight design of equipment, and enhancing reliability and safety.

Abstract

The utility model discloses a battery module and battery pack. The battery module includes support and a plurality of electric core, is equipped with the accommodation space in the support, and the electric core is arranged in the accommodation space, and the electric core is arranged in at least one direction along its width direction and length direction single layer, and the support is equipped with first outer surface and second outer surface along the thickness direction of electric core, and the electric core is located between first outer surface and second outer surface, and the difference between first outer surface and second outer surface is 0mm~1mm with the thickness sum of electric core and support. In the utility model, since the electric core is arranged in the accommodation space of support single layer, and the distance between first outer surface and second outer surface is controlled in 0mm~1mm with the thickness sum of electric core and support, ensure that the whole structure is compact and has little influence to the increase of battery module thickness, reduce own thickness, and very good fit the pursuit of the light and thin design of battery module of numerous equipment currently.
