AI Technical Summary

Technical Problem

In the event of thermal runaway, existing battery devices can easily release high-temperature gases into the external environment, leading to reduced reliability and posing risks of explosion and fire.

Method used

A cooling component is added to the battery device, including a housing and an insulating component. The housing has a receiving cavity. The insulating component melts at high temperature, releases a cooling medium to exchange heat with the high-temperature gas, reduces the gas temperature, and is discharged through a pressure relief mechanism.

Benefits of technology

It effectively reduced the temperature of the high-temperature gas, improved the reliability of the battery device, reduced the risk of explosion and fire, and ensured the safety of the battery device.

Abstract

The application provides a battery device and a power utilization device. The battery device comprises a box body, a battery monomer and a cooling component. The box body comprises a containing space and a first beam. The first beam comprises an exhaust passage and a first through hole. The first through hole is connected with the containing space and the exhaust passage. The battery monomer is arranged in the containing space. The cooling component is arranged at least partially in the exhaust passage. The cooling component comprises a containing cavity for containing a cooling medium. The cooling component is configured to be actuated when the temperature of the exhaust passage is greater than a threshold value, so that the cooling medium is released into the exhaust passage. In the embodiment of the application, the cooling component is additionally arranged in the first beam. When the battery monomer is in thermal runaway, the cooling component can be actuated under the action of high-temperature working conditions in the exhaust passage, so that the internal cooling medium can be released. In this way, the temperature of the gas discharged from the battery device to the external environment is reduced, and the use reliability of the battery device is improved.
