Charge-Discharge Testing
Charge-discharge testing is the most direct method to judge battery performance. Its test results determine whether a battery can be used, needs improvement, or in which field it can be applied. Charge-discharge tests are also conducted to check battery capacity and verify performance indicators such as capacity, efficiency, and safety. Through charge-discharge cycle testing, the changes in lithium battery charge-discharge capacity, coulombic efficiency, etc., with charge-discharge cycles can be directly observed. After data analysis, the cycle performance of the lithium battery can be analyzed and judged.
Initial charge-discharge test, cycle charge-discharge test, rate charge-discharge test, high and low-temperature charge-discharge test, constant current and constant voltage charge-discharge test, fast charge-discharge test, deep discharge test, partial charge-discharge test, test charge-discharge program, 25°C initial charge-discharge performance test.
