According to the subsidy policy for new energy vehicles in 2019, pure electric vehicles with driving range less than 250km will no longer enjoy the national subsidy, and the subsidy for pure electric vehicles with driving range more than 400km will also be reduced to 25000 yuan. At a time when subsidies for new energy vehicles have declined significantly, many enterprises have made rational thinking about the driving range of pure electric vehicles. Recently, Xu Heyi, chairman of BAIC Motor Corporation, said publicly: "The driving range of new energy vehicles will be gradually standardized in the future. In my opinion, the driving range of about 300 kilometers is a very economic and reasonable value."
Cost reduction starts from reducing battery consumption
Xu Heyi said: "With the development and popularization of power change technology, the problem of mileage anxiety of new energy vehicles will be solved well. New energy vehicles will change their power when they have no power, just like fuel vehicles. Under the power change mode, 300 kilometers is the most appropriate driving range. Because the driving range is too short, it is not convenient for users to change power frequently. Because it is convenient to change power, it is meaningless to blindly pursue high driving range."
Xu Heyi believes that the most reasonable driving range of a pure electric vehicle is 300 kilometers, because the energy consumption of such pure electric vehicles is relatively economical. He said: "If the driving range of a pure electric vehicle is to reach 600km, the battery quality it is equipped with is twice as high as that of a pure electric vehicle with a driving range of 300km. Idling aside, the increase in the dead weight of the battery will also aggravate the wear on the tires, and the operating cost will also increase significantly. The operation of a pure electric vehicle with a driving range of 600km is essentially the battery that consumes electricity to carry the battery itself, which will consume a lot of energy at the same time. We have After measuring and calculating various comprehensive factors, the conclusion is that 300 kilometers is enough for a pure electric vehicle. "(Lithium - Ion Battery Equipment)
As an important core component of the pure electric vehicle, the battery provides power for the vehicle, but also increases the vehicle weight. How to achieve the balance between vehicle weight and driving range is the core of realizing economy of pure electric vehicle. Therefore, both the national subsidy policy for new energy vehicles and the local government subsidy policy for new energy vehicles put forward requirements for 100 km energy consumption of pure electric vehicles. Especially in the early stage of demonstration and promotion of new energy vehicles, the Shanghai Municipal Government has made it clear that only new energy vehicles with 100 km energy consumption of pure electric vehicles within a certain range can receive local subsidies. At that time, this regulation was regarded as the threshold for BYD to enter Shanghai under the local protection of Shanghai and refuse to carry a large amount of batteries in disguised form. However, no matter whether the Shanghai Municipal Government is really carrying out local protection, it is the direction that new energy vehicles must promote to require vehicles to control energy consumption and improve energy utilization. Therefore, at that time, some experts in the industry proposed to reasonably control the driving range of vehicles and not blindly increase the carrying capacity of batteries. Lin Yi, then the chairman of BAIC BJEV, once said that, based on the comprehensive consideration of such factors as the energy density of the battery at that time, 160 kilometers was a reasonable driving range for pure electric vehicles. With the improvement of power battery energy density and the increasing number of charging facilities, it seems that 300km is a reasonable driving range for pure electric vehicles.
As we all know, battery is the highest cost of all parts of pure electric vehicle, and more batteries mean the increase of vehicle cost. This part of the cost will eventually be reflected in the vehicle terminal price as the subsidy for new energy vehicles declines or even withdraws. In the last round of new energy vehicle subsidy policy, pure electric vehicles with extra long driving range can get high subsidies, which leads to the phenomenon that the price of some pure electric vehicles with doubled driving range is not much different or even the same as that of pure electric vehicles with only half of their driving range. With the withdrawal of subsidies for new energy vehicles, such "cheap" long mileage vehicles will no longer exist. This part of the cost will be directly borne by consumers.
