As the number of electric vehicles is increasing year by year, the accuracy of electric vehicle cruising range estimation in high and low temperature environments is one of the performances that consumers are very concerned about. In this paper, the accuracy of cruising range estimation is evaluated by the determination of coefficient, and the influence of ambient temperature on the estimation accuracy of cruising range is deeply studied. Eleven electric vehicles were selected to carry out the cruising range test at normal temperature, high temperature and low temperature respectively, and the influence law at ambient temperature of the accuracy of cruising range estimation was obtained. At the same time, the influence of the self-learning function on the accuracy of the cruising range estimation is also studied. Finally, the performance of the estimation of accuracy of the end mileage at different ambient temperatures is analyzed.
