Study on the Factors Affecting DCR Test of Lithium Ion Battery
Owing to high energy density and long life,lithium ion battery is widely used in portable electronic equipment,electric vehicles and other fields.As a basic and critical parameter,DCR can effectively reflect the internal resistance of batteries,and provide a reference of performance differences and failure mechanisms of batteries.Therefore,taking DCR test as the research object,this paper mainly studies the effects of experimental variables on the consistency of DCR test results,such as temperature fluctuation in test environment,equipment selection and its accuracy,and standing time after pretreatment.And suggestions about the corresponding improvement have been put forward meanwhile.
