The research of this paper is based on the data of connected electric vehicles in Beijing. Firstly, electric vehicle trips are extracted with the type of charging behavior, and potential factors influencing the fast charging behavior are analyzed. Then, a logistic regression model is developed to identify the factors influencing the fast charging behavior, which includes available driving ranges, travel distance, and travel time. Finally, based on the significant influencing factors, a model is established to predict the fast charging behavior of private EVs. The prediction results show that the model has good prediction performance. The research results could help to optimize the charging behavior of private electric vehicles and improve the charging efficiency.
