Three Mandatory National Standards for the Auto Industry Open for Public Comment
TapTechNews August 21st news, the official website of the Ministry of Industry and Information Technology publicly solicits opinions on three mandatory national standards today, and the deadline for soliciting opinions is October 20th, 2024, including:
Evaluation Method and Index of Fuel Consumption of Passenger Cars
Limit of Energy Consumption of Electric Vehicles - Part 1: Passenger Cars
Safety Technical Specifications for Three-Wheeled Vehicles
TapTechNews learned from the draft for comments of the most concerned Limit of Energy Consumption of Electric Vehicles - Part 1: Passenger Cars that the standard is applicable to M1 class pure electric vehicles with a maximum designed gross mass not exceeding 3500 kilograms. The standard stipulates the limit of energy consumption of pure electric passenger cars, the application and determination of type approval, production consistency, and the judgment of the same type, etc..
The main technical changes in this revision are mainly:
Combined with national management requirements, technological progress expectations, and the impact of working condition switching, the limit requirements for the energy consumption of passenger car models are updated. By raising the threshold requirements for the energy consumption of vehicle models, it will effectively reduce the energy consumption level of vehicle models and curb the development trend of vehicle enlargement, and prevent the rebound of the existing overall average energy consumption level..
In November 2020, the New Energy Vehicle Industry Development Plan (2021-2035) issued by the State Council proposed: By 2025, the average electricity consumption of new pure electric passenger cars will be reduced to 12.0 kilowatt-hours per 100 kilometers, and the sales volume of new energy vehicles will reach about 20% of the total sales volume of new cars.
Based on the limit requirements of regular models and special models and the current electricity consumption performance of various models, it is found that the overall compliance rate of the current stage model industry exceeds 60%, it is expected that about 30% of the models can meet the limit requirements through appropriate technical upgrades after the implementation of the standard, that is, it is expected to eliminate about 10% of the technologically backward models after the implementation of the standard..
The file mentioned that in the past three years, the average vehicle weight of electric passenger cars has been continuously increasing, and the electricity consumption level has also increased. Although it has reached nearly 12 kWh/100 km in 2020, there has been no further improvement in the past three years.
Based on the overall situation of vehicle weight in recent years, the reference mass of the limit requirement is determined to be 1780 kilograms, and with the increase of the mass of regular models compared to traditional cars (1580 kilograms → 1780 kilograms), increase the2510 kilograms mass inflection point by 200 kilograms to 2710 kilograms.
In terms of the low mass inflection point, the limit standard of the sixth stage of passenger cars will be adjusted to 1090 kilograms. There are a total of 8 industry-related feedback opinions, all hoping to adjust to 1090 kilograms. After comprehensive consideration, the standard will synchronously adjust the low mass inflection point to1090 kilograms.
The file stated that during the drafting process of the standard, the drafting group widely solicited the opinions of the members of the standard working group on the scope of application of the standard, limit requirements, mass inflection points, the particularity of limit requirements of four-wheel drive models and three-row seat models, etc. After discussion, it was determined that the scope of application of the standard continued the current standard version; the limit requirements were determined after appropriate adjustments considering the industry development based on the current average level of the industry; the low mass inflection point was adjusted from 750 kilograms to 1090 kilograms; the relaxation requirement of three-row seat models was maintained, and the relaxation requirement of four-wheel drive models was added, and the strict requirement of models with a lower maximum speed than the working condition was cancelled.
