Design of accelerated life experiment teaching method of retired power battery
In order to accurately estimate the life of retired power batteries,the key point of the re-search is to make rational use of it.It is also an important part of experimental teaching at universities.Therefore,the retired power battery is studied by an accelerated life test method based on the inverse power law model.This experiment method involves a number of theoretical basics such as the use of e-quipment and simulation software,and systematically trains students'data query,test operation and a-nalysis abilities.Firstly,the charge and discharge experiments of retired power batteries are carried out at different rates,and the correlation characteristics between discharge rate and health degree is estab-lished;Secondly,the accelerated life test platform of power battery is built,and different discharge rate is selected as the accelerated stress to carry out the accelerated life test;Finally,through the com-parative analysis of simulation and actual test,the life attenuation characteristics of power battery are further determined,which provides a reference for the research of echelon utilization of power battery.In addition,through the organic combination of simulation experiment and teaching platform,students'practical comprehensive ability of practical engineering application and development can be improved.
