In high and low temperature environments, especially in high-speed scenarios, the estimation accuracy of the range of electric vehicles is a pain point which is more concerned by consumers. Based on the China light-duty vehicle test cycle for passenger car, this paper deeply studies the estimation accuracy of the range of electric vehicles under different ambient temperature conditions. Further, a complex test cycle including long-distance in high-speed driving conditions is constructed, and the influence rule of the complex test cycle and high-speed vehicle speed on the estimation accuracy of cruising range is compared and analyzed through actual vehicle tests.
