Research on Forcasting Method of Lithium Battery SOC

In order to predict the state of charge(SOC) of batteries for electric vehicle(EV),by analyzing the factors influencing the SOC of batteries,on the basis of charge and discharge test experiments of battery packs in different operating cases,an artificial neural network simulation model was set up.The author proposed a predictive SOC model based on BP neural network.The model can approach the non-linear function with many input/output parameters.By comparing simulation results with experimental results,simulation results are verified by experimental results,which can prove the correctness of the simulation method.
