The modeling of energy consumption of electric vehicles is of great significance for meticulous depiction and evaluation of energy saving driving control effect of electric vehicles. Compared with the mesoscopic energy consumption model based on the driving segment, the proposed model can be more accurately estimated. The energy consumption of electric vehicles is generally suitable for detailed characterization of the energy consumption characteristics of electric vehicles, as well as the quantitative estimation of the energy consumption of electric vehicles in small areas such as roads and intersections. In this paper, the driving data of electric vehicle is acquired by the actual driving mode of outdoor roads. The energy consumption model of electric vehicle is established based on the analysis data. Finally, various driving control modes and their energy efficiency improvement are analyzed and evaluated.
