Research on impact test methods and parameters of Li-ion battery
In the use and transportation of Li-ion battery with high energy density,collisions are inevitable,quality control is particularly important.After being physically hit,the batteries may have internal short circuits.To test the comprehensive quality of the finished batteries,reliability testing is required before leaving the factory.The methods and reasonable parameter setting of octagonal-drum equipment in reliability testing are introduced.By using motion simulation to simulate the impact parameters of the batteries in the drum,collecting the data of the batteries after testing,it is used to determine whether the quality of the batteries reaches the engineering capability of six sigma(6σ).
