Problems solved by technology

[0002] In the related technology, it is difficult to design the battery module in the form of a module without an automatic fire extinguishing system. Most of the fire protection systems are installed on the PACK system or not at all. Because the size of the PACK installed in the PACK system varies, It is difficult to realize that it can be arranged in place at every angle, so there is a problem that the system response time lags and the extinguishing is not in place

Abstract

The invention discloses a deformation assembly for a battery, a battery, a battery pack and a vehicle. The deformation component includes a housing component, a sealing membrane and a temperature-sensitive deformation sheet. The housing assembly defines an accommodating cavity for accommodating inert gas, one end of the accommodating cavity has an opening, and a sealing film is arranged at the opening to seal the accommodating cavity. The deformation sheet is arranged in the accommodation cavity, and the deformation sheet is provided with a piercing protrusion, and when the deformation sheet is deformed, the piercing protrusion punctures the sealing film. According to the deformation component for battery of the present invention, by utilizing the temperature sensitivity of the deformation sheet, the sealing film can be pierced by the piercing protrusion when it is deformed, and the inert gas in the accommodating cavity can be released. By detecting the state of the deformed component by detecting the inert gas, the working state of the battery can be detected. Therefore, it is convenient to monitor the state of the battery, and the abnormal heating condition of the battery can be found in time, thereby improving the working safety and stability of the battery.

Description

technical field [0001] The present invention relates to the technical field of batteries, in particular, to a deformation component for batteries, a battery, a battery pack and a vehicle. Background technique [0002] In the related technology, it is difficult to design the battery module in the form of a module without an automatic fire extinguishing system. Most of the fire protection systems are installed on the PACK system or not at all. Because the size of the PACK installed in the PACK system is large or small, It is difficult to realize that it can be arranged in place at every angle, so there is a problem that the system response time lags and the extinguishing is not in place. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. For this reason, the present invention proposes a deformable assembly for batteries, which has the advantages of simple structure and sensiti...
