Aiming at problems of accumulate-errors of Ampere-hour integral( AH) method and limitation of Kalman filtering algorithm on noise
a scheme of correction accumulate-errors of AH with particle filtering( PF) is given. Based on LCO battery testing data and model for battery equivalent circuit
the algorithm is verified by using simulation. Compared with AH method and Kalman filtering algorithm
the algorithm of AH with PF correction is better on estimation of state of charge( SOC)
average error and standard error are both less than 2 %.
