Abstract
Four model based SOC estimation methods for Lithium-ion (Li-ion) batteries are studied and compared in this paper. The equivalent model of the battery is described and the state function of the model is deduced. The analysis of the four model based SOC estimation methods are given. The simulation is established to evaluate the four methods. The urban dynamometer driving schedule (UDDS) current profiles are applied to simulate the drive situations of an electrified vehicle. Simulation results are depicted and analyzed to compare the four model based SOC estimation methods.
