Cycle Life under different DOD, Ambient Temperature, Discharge Current

Cycle life is a key parameter for Lithium ion battery especially for storage application. Cycle life is primarily affected by the depth of discharge (DOD). However, ambient temperature and discharge current also play minor role. Ambient temperature is different from the temperature measured on the body of the battery cell. Here assuming there is sufficient …
