Abstract: At present, the range of electric vehicles is affected by many factors. Firstly, this paper analyzes which external factors will affect the range and the specific reasons, and then establishes the relevant mathematical theoretical formula. Through the simulation of Matlab, the curve is obtained for analysis. It is concluded that the main factors affecting the range are windward area, system efficiency, body weight, rolling resistance, battery capacity and air resistance. According to the results of the above factors, the optimization analysis is carried out to maximize the range of electric vehicles, and provide feasible suggestions.
