Abstract :
The input variables of adaptive neuro-fuzzy inference model are selected by correlation analysis based on the parameter options of NiMH batteries. The output characteristic of NiMH battery is generalized by Expert experience, and the ANFIS model is established including the selection of input variables and membership functions. Then the fuzzy rules are adjusted by BP neural network algorithm and least-squares algorithm. The data used in model identification and model validation is close to the data of actual working condition. The SOC estimation method of adaptive neural fuzzy inference combines the advantages of fuzzy inference and artificial nerve network.
