Abstract

In order to apply the lithium-ion batteries on the electric vehicles reliably and safely, estimating the internal statements of the batteries, such as the state-of-charge (SOC) is obligatory. The purpose of this work was to present a SOC estimation method named parallel arithmetical unscented Kalman filter which has obvious advantages that was validated by simulation. In this paper, a lumped circuit model and the parameter identification method were studied. And the state-space type battery model was derived. Then a novel SOC estimation method was proposed using the parallel arithmetical unscented Kalman filter (PAUKF) technique. Validation results showed that the presented SOC estimation algorithm could have an acceptable performance with the mean error less than 2.4%.
