Battery models play a very important role in the battery management system(BMS), especially in the estimation of state of charge(SOC). Among different kinds of models, equivalent circuit models are proved more practical and flexible. In this paper, the definition of SOC and influence factors are firstly discussed, and then some equivalent circuit models of batteries in EV will be reviewed, finally...
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...
