According to the 2019 new energy vehicle subsidy policy, pure electric vehicles with a driving range of less than 250 kilometers will no longer enjoy state subsidies, and the subsidies for pure electric vehicles with a driving range of more than 400 kilometers have also dropped to 25,000 yuan. At a time when subsidies for new energy vehicles have declined sharply, many companies are thinking rationally about the driving range of pure electric vehicles. A few days ago, Xu Heyi, chairman of Beijing Automotive Group, publicly stated: “In the future, the mileage of new energy vehicles will be gradually standardized. In my opinion, a mileage of about 300 kilometers is a very economical and reasonable value.”
Cost reduction starts with reducing battery usage
Xu Heyi said: “With the development and popularization of battery replacement technology, the problem of mileage anxiety of new energy vehicles will be well resolved. When new energy vehicles run out of battery, replace the battery, just like refueling a fuel vehicle. In the battery replacement mode Under the circumstances, the most suitable driving range is 300 kilometers. Because the driving range is too short, it is inconvenient for users to change batteries frequently. Because it is convenient to change batteries, it is meaningless to blindly pursue high driving range.”Also read:Marine Lithium Battery
The reason why Xu Heyi believes that the driving range of pure electric vehicles is 300 kilometers is the most reasonable because the energy consumption of such pure electric vehicles is more economical. He said: “If the driving range of a pure electric vehicle is to reach 600 kilometers, the quality of the battery it is equipped with is twice that of a pure electric vehicle with a driving range of 300 kilometers. Not to mention idling, the weight of the battery will increase, and it will also aggravate the problem. The wear and tear on the tires will also greatly increase the operating cost. The operation of a pure electric vehicle with a driving range of 600 kilometers is essentially a battery consumption to carry the battery itself, which consumes electricity and consumes a lot of energy per 100 kilometers. We pass Based on the calculation of various comprehensive factors, it is concluded that a mileage of 300 kilometers for pure electric vehicles is sufficient.”
As an important core component of a pure electric vehicle, while the battery provides power for the vehicle, it also increases the weight of the vehicle. How to achieve the balance between vehicle weight and driving range is the core of pure electric vehicles to achieve economy. Therefore, whether it is the national new energy vehicle subsidy policy or the local government’s new energy vehicle subsidy policy, there are requirements for the energy consumption of pure electric vehicles per 100 kilometers. Especially in the early days of the demonstration and promotion of new energy vehicles, the Shanghai Municipal Government made it clear that only new energy vehicles with energy consumption per 100 kilometers of pure electric vehicles within a certain range can receive local subsidies. At the time, this regulation was regarded as the threshold for Shanghai’s local protection and the rejection of BYD, which has a large battery capacity, to enter Shanghai in disguise. However, regardless of whether the Shanghai municipal government is really carrying out local protection, it is the direction that new energy vehicles must advance to require vehicles to control energy consumption per 100 kilometers and improve energy efficiency. Therefore, at that time, some industry experts suggested that the driving range of the vehicle should be reasonably controlled, and the battery capacity should not be increased blindly. Lin Yi, then chairman of BAIC New Energy, once said that considering the energy density of batteries and other factors at that time, 160 kilometers was a reasonable driving range for pure electric vehicles. With the increase in the energy density of power batteries and the increasing number of charging facilities, it now appears that 300 kilometers is a more reasonable driving range for pure electric vehicles.
As we all know, batteries are the most expensive of all components in pure electric vehicles, and installing more batteries means an increase in vehicle costs. This part of the cost will eventually be reflected in the terminal price of the vehicle as the subsidies for new energy vehicles are reduced or even withdrawn. In the last round of subsidy policies for new energy vehicles, pure electric vehicles with a long driving range can receive high subsidies, which has led to the price of some pure electric vehicles with double the driving range and half the driving range. The price of pure electric vehicles is similar or even the same. With the withdrawal of new energy vehicle subsidies, such “cheap” long-range vehicles will no longer exist. And this part of the cost will be borne directly by consumers.Recommended reading:72v 200ah lithium battery pack
According to Li Jinyong, president of the New Energy Vehicle Branch of the Automobile Dealers Chamber of Commerce of the All-China Federation of Industry and Commerce, the cost of power batteries plays a decisive role in the terminal price of pure electric vehicles, and will be the fundamental factor in determining consumers’ car purchases. Therefore, car companies must comprehensively consider The cost of using the vehicle. Zhu Huarong, President of Changan Automobile, said in an interview with a reporter from China Automobile News that in the future, when subsidies for new energy vehicles are withdrawn, companies will reconsider the design of pure electric vehicle mileage. Enterprises will no longer blindly pursue ultra-long mileage, but will redefine the mileage of vehicles according to usage needs. From the perspective of vehicle energy consumption and consumer demand, 300 kilometers is a foreseeable mileage that is easier for consumers to accept.
Long driving range is not the best prescription for range anxiety
Previously, the reason why the government and enterprises vigorously developed pure electric vehicles with ultra-long driving range was to solve the problem of range anxiety of pure electric vehicles. Since the demonstration and promotion of pure electric vehicles, consumers generally have mileage anxiety, which has also made all parties continue to regard increasing the driving range of pure electric vehicles as a development goal. tilt. As a result, various car companies have developed pure electric vehicles with ultra-long driving range. However, in Li Jinyong’s view, the ultra-long driving range is not the root of solving mileage anxiety, but the convenience of charging should be improved.
It is also a passenger car, a traditional fuel passenger car, the mileage of one refueling is basically more than 500 kilometers, which seems to have become the benchmark value of the mileage of pure electric vehicles, and various car companies have achieved 500 kilometers with pure electric vehicles. Kilometers or even higher mileage is the goal, and state subsidies also give higher subsidies to vehicles with ultra-long mileage. In fact, ultra-long driving range is not the best prescription to relieve consumers’ mileage anxiety. From the actual application situation, the improvement of charging convenience is more effective. Li Jinyong believes that the so-called mileage anxiety of pure electric vehicles is proposed for traditional fuel vehicles, and the reason why fuel vehicles do not have mileage anxiety lies in their high density of gas stations and short refueling time, which is also the root of their driving range advantage reason. Looking back at the field of new energy vehicles, it can be concluded that improving the convenience of charging pure electric vehicles is an effective way to solve the range anxiety of pure electric vehicles. Once the convenience of charging is solved, the problem of mileage anxiety will be easily solved.
Factors such as charging pile density and charging time are the main factors affecting the convenience of charging. Li Jinyong said that, just like the development of fuel vehicles in my country, with the rapid development of new energy vehicles, the construction and layout of charging piles will be faster and faster, and the coverage will be wider and wider. Fast charging technology will also continue to develop, and the single charging time will become shorter and shorter. Coupled with the innovation of battery replacement mode, these will fundamentally promote the process of charging convenience of new energy vehicles, and then solve the problem of mileage anxiety.
