AI Technical Summary

Technical Problem

After installing battery modules, the base plate of conventional battery devices is prone to downward bending deformation in the middle area, which affects the uniformity of bottom support for individual battery cells and may lead to performance and safety issues for individual battery cells in the long run.

Method used

The base plate with an upwardly protruding pre-deformed part generates elastic deformation during battery module installation, providing continuous upward pre-tightening support force. The combination structure of the frame and prestressed plate ensures stable connection and uniform support between the battery module and the base plate.

Benefits of technology

It enhances the structural rigidity and integrity of the battery module, improves stability and reliability under dynamic conditions such as vibration and shock, and extends the service life and performance consistency of the battery device.

Abstract

The application discloses a battery device and a power utilization equipment. The battery device comprises a box body and a battery module. The box body comprises a bottom plate, and the battery module is arranged in the box body and supported by the bottom plate. In the state of mounting the battery module, the bottom plate is configured to provide upward pre-tightening support for the battery module through elastic deformation. In the technical scheme of the application, the bottom plate of the box body can actively provide pre-tightening support, improve the connection strength between the box body of the battery device and the battery monomer, and improve the overall structural stability of the battery device.
