Paper Title:
Research on SOC Estimation of LiFePO4 Battery in HEV
  Abstract

For power distribution between engines and electric motors and the dynamic battery management SOC of the dynamic battery in HEV is an important parameter. To estimate SOC accurately LiFePO4 Battery was taken as study object in this paper and based on the characteristic experiments of the LiFePO4 Battery a new combining algorithm of estimating SOC has been put forward which combined Ah counting method, equivalent circuit model and open circuit voltage method. The simulation model of SOC algorithm in MATLAB was created in the paper and the results of simulation have indicated that the new strategy of estimating SOC was feasible and accurate.
