Abstract

Lithium-ion batteries will undergo continuous aging during the process of charging and discharging. Charging and discharging cycle conditions for lithium-ion batteries are usually an important method to detect the degree of aging of lithium-ion batteries. However, the general aging cycle lasts for thousands of cycles, which is more time consuming. The charge/discharge capacity of the original condition and the accelerated condition are guaranteed to be the same, and the aging path is essentially the same way. The accelerated life test of lithium-ion battery is realized by the constant current rate accelerated operating condition design and the variable current rate accelerated operating condition design with two different constraints, and the accelerated operating condition with the minimum difference between the battery aging path of the original operating condition before acceleration is obtained by the optimization method.
