Title: Characteristic on internal resistance of lithium-ion power battery
Abstract: For in-depth analysis internal resistance of power lithium-ion battery and the relationship between factors,hybrid pulse power characterization(HPPC) method is used for testing internal resistance of lithium-ion battery under the different temperatures and the stage of charge(SOC) in this paper.The results show that the power lithium-ion internal resistance has changed significantly at low temperature and SOC.Finally,the relationship expression between the power lithium-ion battery internal resistance and the temperature was proposed by polynomial least square curve fitting,it provides a theoretical basis and data support for the battery power online prediction.
