On April 28, the Ministry of Industry and Information Technology officially released the “Key Points for Automotive Standardization Work in 2025.” This initiative aims to lead the transformation and upgrading of the automotive industry through standardized practices, focusing on critical areas such as green low-carbon technologies, smart connectivity, and safety assurance. Among the 15 key tasks outlined, the implementation of core standards related to passenger vehicle fuel consumption evaluation and electric vehicle energy consumption limits has garnered significant industry attention.
In the realm of green low-carbon initiatives, the document highlights the acceleration of the release and implementation of two mandatory national standards: the “Evaluation Methods and Indicators for Passenger Vehicle Fuel Consumption” and the “Energy Consumption Limits for Electric Vehicles.” The former serves as a fundamental basis for automotive energy-saving management and completed its public consultation for approval in March 2025, utilizing a linear limit evaluation system based on vehicle curb weight. The latter focuses on the energy efficiency management of electric vehicles throughout their entire lifecycle, detailing energy consumption testing methods under various operating conditions to provide technical benchmarks for the optimization of key components like power batteries and drive motors.
These two standards will work in conjunction with accompanying standards such as the “Monitoring of Onboard Energy Consumption for Passenger Vehicles” and “Pure Electric Utilization Coefficient for Light Hybrid Vehicles,” creating a comprehensive energy consumption control system that spans vehicle research, production, and usage.
Simultaneously, the safety standard system for new energy vehicles is being upgraded. The safety requirements for power batteries have entered the implementation phase, and standards for durability and thermal management systems are currently under review. The development of standards for cutting-edge technologies, including solid-state batteries and in-service testing, is also accelerating.
For commercial vehicle battery swap scenarios, safety requirements for battery swapping are set to be released soon. The establishment of standards for charging performance and compatibility testing is underway, and preliminary research on megawatt-level charging standards has commenced, providing technical support for the large-scale application of electric heavy-duty trucks and other commercial vehicles.
Regarding international strategies, the document outlines a goal to increase the international standard conversion rate for the automotive industry to over 85%, stating that mandatory national standards should be fully translated. The Ministry will leverage the platform of the United Nations World Forum for Harmonization of Vehicle Regulations (WP.29) to lead the development of key regulations related to autonomous driving systems and vehicle battery durability, while also advancing international standard projects related to electric vehicle performance and electromagnetic compatibility. The development process for international standards concerning onboard radar and fuel cell systems will be expedited.
Industry experts point out that this round of standard updates will reshape the competitive landscape of the automotive industry. Under the dual constraints of passenger vehicle fuel consumption and new energy vehicle point systems, automotive manufacturers must adopt technological upgrades, such as lightweight materials and hybrid systems, to meet energy consumption standards. The standard system for smart connected vehicles will impose higher demands on the collaborative development capabilities of hardware and software among manufacturers. As the standard system continues to evolve, China’s automotive industry is set to accelerate its transition towards a phase of high-quality development characterized by technological innovation, safety, and green low-carbon practices.
