AI Technical Summary

Technical Problem

The existing battery packs have insufficient protection capabilities, which means they cannot effectively protect the battery cells when subjected to impact loads.

Method used

A receiving cavity is set in the battery pack housing, and the battery cells are located in the receiving cavity. A crushing structure is provided between the bottom protective plate and the bottom of the cavity, including a first connecting beam and a cold plate. The crushing structure absorbs impact loads and enhances the bottom protection capability of the battery pack.

Benefits of technology

By absorbing impact loads through the deformation characteristics of the crushable structure, the direct impact on the enclosure is reduced, improving the protection capability of the battery pack. Furthermore, the cooling channels and buffer materials enhance heat dissipation and energy absorption efficiency.

Abstract

This application discloses a battery pack, including: battery cells, a housing, a bottom protective plate, and a crushing structure; the battery pack has a first direction, a second direction, and a third direction that are perpendicular to each other; the housing has a receiving cavity, the receiving cavity having an opening and a bottom arranged opposite to each other along the third direction, and the battery cells are disposed in the receiving cavity; the bottom protective plate is disposed on the side of the bottom of the cavity away from the receiving cavity; the crushing structure is disposed between the bottom protective plate and the bottom of the cavity, one side of the crushing structure is connected to the housing, and the other side of the crushing structure is connected to the bottom protective plate. In this way, the housing and the bottom protective plate can be connected by the crushing structure, thereby preventing the housing from being directly impacted when the battery pack is subjected to impact loads; at the same time, the crushing buffer structure's more easily deformable characteristics further absorb impact loads, reducing the impact on the bottom of the housing and improving the bottom protection capability of the battery pack.
