On December 3, the Ministry of industry and information technology officially released the new energy vehicle industry development plan (2021-2035) (Draft for comments), which described the development trend, overall deployment, strategic planning and other contents of China's new energy vehicles, and gave specific objectives in the key technology research projects of new energy vehicles. By 2025, the average power consumption of new passenger vehicles will be reduced to 12kwh / 100km, (including) passenger vehicles The average fuel consumption of new cars is reduced to 2.0l/100km. "New energy PHEV" is different from "energy saving and new energy vehicle industry development plan (2012-2020)". In the draft, the maximum speed index of pure electric and plug-in hybrid passenger vehicles is deleted, the indexes of driving distance, specific energy of power battery and cycle life are cancelled, and the power density index of electric drive system is no longer mentioned, but the "average fuel consumption" is proposed separately And the concept of "average power consumption". According to the terms of the draft, the average fuel consumption is the "average fuel consumption", which is the average fuel consumption of a group of vehicles calculated by weighted average of the number of vehicles corresponding to the vehicle type. With reference to the latest batch of catalogue of energy saving new energy vehicles enjoying vehicle and ship tax reduction and exemption published by the Ministry of industry and information technology, there is still a certain distance between all plug-in hybrid passenger vehicles and the distance of 2l / 100km. Among them, the average fuel consumption of linker 01 new energy PHEV is 4.8l/100km, which is the product with the lowest average fuel consumption among all models. It can be seen that in 2025, the number of plug-in hybrid passenger vehicles will be reduced to 2L / 100km, which requires continuous efforts of major enterprises. The "2018 model" average power consumption is the "average power consumption of pure electric passenger vehicles", which is the average power consumption of a group of vehicles calculated by weighting the number of vehicles corresponding to the vehicle model. Referring to the promotion and application of new energy vehicles (the 10th batch in 2019) issued by the Ministry of industry and information technology, the average power consumption of six pure electric cars is less than 12kwh / 100km, including 9.9kwh/100km for a pure electric car of SAIC GM Wuling and 17.9kwh/100km for a Tengshi pure electric car. It can be seen that the greater the self weight, the more difficult it is to reach the 12kwh / 100km index. Some insiders believe that the average power consumption index of new pure electric passenger vehicles in the draft for comments should be cancelled. On the one hand, the power consumption should not be simply compared with the fuel consumption. At present, the thermal efficiency of gasoline vehicles is about 30%, while the working range with the efficiency of the drive motor system higher than 80% accounts for more than 80%. Compared with the engine, the space for improving the motor theory is very limited. On the other hand, setting power consumption targets may constrain the development of ICV. With the development of intelligent network, more and more sensors, lidar and other intelligent components will greatly increase the power consumption. The development of automobile and automobile, automobile and network, automobile and infrastructure, automobile and pedestrian will also lead to the increase of electric vehicle power consumption.
