Abstract: The penetration rate of new energy continues to grow, but "range anxiety" is still one of the important factors restricting consumers to buy new energy vehicles. Compared with the unity of the announced working conditions, the actual vehicle use scenario is more complex, and the models with different positioning have obvious vehicle use scenario distribution. This paper is based on the vehicle use scenario distribution of big data statistics. Compare the relationship between different matching schemes of electric drive systems and the actual road achievement rate, it is found that the speed ratio adjustment or the design of high efficiency zone distribution of electric drive can improve the endurance achievement rate in vehicle scenarios while ensuring that the announced working conditions are not affected.

Key words: Electric vehicle; Driving scenario; Electric drive matching; Endurance achievement rate
