Accuracy of range estimation of pure electric vehicles under compound conditions comparative analysis

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 highspeed vehicle speed on the estimation accuracy of cruising range is compared and analyzed through actual vehicle tests.
