AI Technical Summary

Technical Problem

The battery device has shortcomings in temperature control, especially the problem of heat accumulation at the electrode terminals, which affects reliability and safety, and is prone to thermal runaway, especially during fast charging.

Method used

An air inlet and an air outlet are provided on the battery housing, so that the electrode terminals are located in the airflow path between the air inlet and the air outlet. The airflow directly exchanges heat with the electrode terminals, and the heat generated by charging and discharging is carried away by the airflow inside the housing, thereby improving the temperature control capability.

Benefits of technology

It effectively reduces the temperature of the electrode terminals, improves their reliability, alleviates the temperature rise problem during fast charging, and enhances the temperature control capability and overall reliability of the battery device.

Abstract

The application relates to the technical field of battery-related technologies, and discloses a battery device and a power utilization equipment. The battery device comprises a box body and a battery monomer. The box body is internally provided with an accommodating space. The box body is provided with an air inlet and an air outlet. The air inlet and the air outlet are communicated through the accommodating space. The battery monomer is arranged in the accommodating space. The battery monomer is provided with an electrode terminal. The electrode terminal is located on an airflow flow path between the air inlet and the air outlet. During the charging and discharging process of the battery device, airflow can directly contact the electrode terminal and take away the heat generated during the charging and discharging process. The cooling capacity of the electrode terminal is improved, the reliability of the electrode terminal is improved, the temperature rise problem generated during the fast charging process of the battery device is relieved, the temperature regulation capacity of the battery device is improved, and the reliability of the battery device is improved.
