Experimental Study on Depth of Discharge and Cycle Life of Lithium-Ion Battery

Abstract:

To find out how depth of discharge affecting cycle life of lithium-ion power battery, an experiment was conducted. Three samples of lithium-ion were tested separately with BAITE charge/discharge equipment. Condition of test was set as the same except depth of discharge. Capacity remaining of samples was recorded during testing. Based on processing and analysis of data of the testing, cycle life model of lithium-ion power battery with parameter of depth of discharge was deduced, which was verified by the experimental data. The model provided a theoretical calculating method of cycle life, which would be helpful for precise management of the lithium-ion battery.
