Introduction
This standard is an important measure for the implementation of the Plan for the Medium- and Long-term Development of the Automobile Industry. It aims to promote the development and application of advanced energy-saving technologies in automobiles of China, continuously reduce the fuel consumption of passenger cars in China, and promote the rapid and healthy development of the new energy automobile industry, so as to reduce the average fuel consumption of passenger cars in China to about 4 L/100 km by 2025, corresponding to approximately 95 g/km of carbon dioxide emissions.
To encourage the development of new energy vehicles, concessions are made in the determination up to the year 2025 of the fuel consumption and the corporate average fuel consumption (CAFC) for passenger cars of battery electric vehicle (BEV), off-vehicle-chargeable hybrid electric vehicle (OVC-HEV), fuel cell vehicle (FCV) types.
To encourage the development and application of energy-saving technologies for automobiles, this standard allows to reduce the fuel consumption of vehicle type in CAFC calculation based on the energy-saving effects, in line with the principle of quantitative evaluation, for energy-saving technologies or devices that demonstrate obvious effects in practice which, however, cannot be reflected, or fully reflected, by existing test methods.
