| Abstract: | The establishment of an accurate battery model is a prerequisite for the simulation and verification of battery management strategies,and is the key to a comprehensive,efficient and refined management of power batteries.However,the voltage hysteresis in the charging and discharging process of the power battery seriously affects the modeling accuracy of the power battery.In this paper,a battery model considering the hysteresis of lithium-ion battery charging and discharging voltage is established,and its parameters are identified,which can be used as a reference for scholars engaged in the analysis of related lithium-ion battery status. |
