AI Technical Summary

Technical Problem

Existing testing equipment for the explosion-proof performance of power batteries is unable to accurately simulate the ultra-high-speed impacts that power batteries suffer in real-world application scenarios, resulting in significant discrepancies between test results and actual application conditions, which affects the accuracy and reliability of the assessment.

Method used

An impact loading module, including a high-voltage pulse power supply unit and metal foil, is used to generate a shock wave by triggering an electrical explosion through an instantaneous pulse current. This shock wave propels the flyer plate to impact the power battery at ultra-high speed. The impact information and battery performance parameters are acquired through an information acquisition module and then comprehensively analyzed to evaluate the explosion-proof performance.

Benefits of technology

It enables accurate evaluation of power batteries under extreme testing environments, provides important data support, provides a basis for battery design and material improvement, and enhances testing efficiency and safety.
