【 摘 要 】

The Partnership for a New Generation of Vehicles (PNGV) battery equivalent model is established on the basis of the existing charging state estimation method. Based on the kalman filtering algorithm, a state space expression based on the Davidson's battery model is established. Finally, Matlab/Simulink is used for simulating calculation. Simulation and experiment show that the selected PNGV model has high precision and can simulate the charging and discharging characteristics of the battery truly, so that the SOC estimation value is controlled within the range of high precision.
