This article studied the RC equivalent circuit model of lumped parameters for lithium-ion batteries in electric vehicles.On the base of the traditional battery models,this research creates a new dynamic equivalent circuit model of lithium-ion power battery considering the polarization effect and hysteresis voltage characteristics of battery.Model’s parameters were identified by tests.The estimated error of this model is 2%through experimental analysis,which is more accurate than the traditional first-order and second-order models and simpler than the third-order RC model.
