AI Technical Summary

Technical Problem

In existing technologies, the lack of battery sealing performance and the failure of the explosion-proof sheet lead to the accumulation of internal pressure in the battery, causing safety accidents.

Method used

A new energy battery testing device is adopted, which includes a lower mold assembly, an upper mold assembly, a mode switching mechanism, a linear reciprocating mechanism, and a support assembly. Through the linkage between the pad block and the support block, the sealing performance and explosion-proof performance of the battery box can be quickly switched for testing. The breathing module is used to simulate the internal pressure change of the battery to ensure reliable protection of the explosion-proof membrane. The design of the demolding arm simplifies the picking and putting of the battery box.

Benefits of technology

It significantly improves the safety and accuracy of battery testing, can accurately assess the fatigue life and reliability of the explosion-proof film, ensures the stability of the battery during charge and discharge cycles, and simplifies the battery box loading and unloading process.

Abstract

The application discloses a new energy battery testing device and relates to the field of battery testing.The device comprises a lower mold assembly, the lower mold assembly comprising a battery seat provided with a mounting port, and a cushion block arranged in the mounting port; an upper mold assembly, the upper mold assembly comprising a pressing plate which is lifted above the battery seat and is provided with an anti-explosion testing air hole and a box body testing air hole; a mode switching mechanism, the mode switching mechanism comprising two groups of breathing modules which are fixed on the pressing plate and are connected through valves, and the two groups of breathing modules are communicated with the anti-explosion testing air hole and the box body testing air hole respectively; a linear reciprocating mechanism, the breathing modules are driven to reciprocatingly stretch and retract by the linear reciprocating mechanism to realize anti-explosion sheet breathing cycle testing; and a supporting assembly, the supporting assembly comprising a plurality of supporting blocks which are slidably inserted into the battery seat, and the cushion block is used for anti-explosion sheet testing after being supported by the supporting blocks, so that the problem that safety accidents are caused by the accumulation of internal pressure of the battery due to the loss of the sealing performance of the battery and the failure of the anti-explosion sheet is solved.
