With the gradual popularization of new energy vehicles, the shrinkage or even jump in winter mileage is the pain point of the industry, and how to improve the low-temperature mileage has become the focus of technological innovation of major car companies. On December 31, 2021, China Automotive Engineering Research Institute Co., Ltd. released the "China Small New Energy Vehicle Low Temperature Endurance White Paper", after comparative testing, Wuling Hongguang MINIEV low temperature mileage retention rate reached 67.5%, higher than the industry average of 59.95%, in the industry leading position. Ouyang Minggao, academician of the Chinese Academy of Sciences, professor of Tsinghua University and deputy director of the academic committee of the university, said that Wuling Hongguang MINIEV's low-temperature mileage retention rate has achieved such excellent results, which is of great significance to promoting the accelerated development of the industry and will promote the comprehensive replacement of small fuel vehicles by small new energy vehicles.

At the beginning of December 2021, in response to the low temperature weather, the Ministry of Industry and Information Technology held a meeting to require vehicle companies, battery companies, research institutions and other companies to strengthen technical coordination and fundamentally promote the solution of low temperature endurance problems. In response to the call of the Ministry of Industry and Information Technology, on December 31, 2021, SAIC-GM-Wuling held the "China Wuling Light of Domestic Goods - New Energy Vehicle Low Temperature Endurance Technology Innovation Conference" in Beijing, inviting expert Wang Zidong of the New Energy Vehicle Production Access Review Group of the Ministry of Industry and Information Technology, Liu Xiaoshi, deputy secretary general of the China Electric Vehicle 100 Association, Ouyang, deputy director of the New Energy Technology Department of the China Automobile Research Institute, Xiao Chengwei, deputy director of the National Automobile Standardization Technical Committee, and other experts and scholars from domestic industries, universities and scientific research institutions. Discussions were held on how to break through the bottleneck of low-temperature endurance technology for new energy vehicles and promote the formulation of new energy-related standards.

Promoter of the construction of China's new energy vehicle standard system
Xiao Chengwei pointed out that Wuling is the promoter of the construction of China's new energy vehicle standard system, and the small pure electric vehicle products launched by Wuling have set a benchmark in the world. Xiao Chengwei suggested that Wuling will make greater contributions to the development of the industry in the standardization of components such as batteries and modules for small pure electric vehicles
Liu Xiaoshi pointed out that China to become the world's leading automobile power, must have an economic car, in the next decade, our small car from A00 level to A0 to B class, which is an important symbol of China's becoming an automobile power, Wuling for the development of global electric vehicles to play a leading role. Liu Xiaoshi said that our core goal is to promote full electrification, and under this goal, we see that Wuling has stepped on the rhythm and walked in the forefront of development.
Enhance the low-temperature endurance experience Wuling new energy products will arm a large number of "black technology"
As a pioneer in the small new energy vehicle market, SAIC-GM-Wuling has accumulated sales of GSEV's global small electric vehicle platform products to exceed 700,000 units. Closely focusing on user usage scenarios and experiences, SAIC-GM-Wuling has achieved excellent performance in improving the low-temperature cruising range of the vehicle by innovating in terms of intelligent battery insulation design and intelligent calibration technology of the vehicle system. In the next step, SAIC-GM-Wuling will promote the advancement of user experience through technology upgrades, and systematically optimize around the various latitudes of new energy vehicles with the design concept of "open source and throttling, intelligent and efficient", so as to meet the needs of users in low-temperature scenarios to the greatest extent. In terms of "open source", around the positive and negative electrode materials of the battery cell, electrolyte formula and other aspects, we continue to explore ways to improve the low temperature performance of the battery cell; in terms of "throttling", through the development of more efficient heat pump air conditioning and waste heat recovery technology, a new upgrade of the vehicle full climate intelligent heat management system, at the same time, the battery intelligent thermal insulation research and development has also entered the 2.0 era, so that the battery "warm in winter and cool in summer"; in terms of "intelligent and efficient", the innovative end cloud multi-dimensional algorithm is integrated to make the low temperature energy estimation more "smart". In the future, these innovative technologies will be successively applied to the follow-up products of SAIC-GM-Wuling new energy vehicles.

Participated in the formulation of 117 standards and was awarded the "leader" of China's new energy enterprise standards
At the press conference, China Automobile Research Institute also issued the "leader" certificate of China's new energy enterprise standard to SAIC-GM-Wuling. In the discussion and test verification of the national new energy "frontrunner" standard, SAIC-GM-Wuling's new energy products have obtained the best first-class evaluation, and the main performance standards have led the industry.

Li Kaiguo, chairman of China Automobile Research Institute, said that SAIC-GM-Wuling actively participated in the formulation of a number of standards in the field of new energy vehicles, improving the quality of small new energy vehicles. The new energy vehicles on the SAIC-GM-Wuling GSEV platform won the title of "frontrunner" of enterprise standards, leading the development direction of small new energy vehicles in China.
In order to promote the high-quality development of the new energy automobile industry, SAIC-GM-Wuling actively promotes the construction of the new energy vehicle standard system, and participates in the formulation of a total of 117 new energy vehicle industry standards, including: 1 international standard, 89 national standards, 18 industry standards, 1 local standard, and 8 group standards. The industry standard "Integrated AC Power Supply Standard Socket for Conductive Charging of Electric Vehicles" that led the drafting for the first time standardized the technical requirements of low-power AC charging on the facility end in the industry; the group standard "AC Charging Socket for Electric Vehicles" led the drafting and release promoted the development of the new energy automobile industry in Guangxi and formed the "Wuling Model"; the national standard "Technical Conditions for Pure Electric Passenger Vehicles" participated in the drafting further standardized the research and development and production of electric vehicles in China, promoted the application of the electric vehicle market, and strengthened the management of electric vehicles To promote the healthy development of the electric vehicle industry.
Academician Ouyang Minggao pointed out in his concluding speech that only when the standard of new energy vehicles moves towards standardization, can the entire industry move towards maturity, and vigorously promote the formulation of new energy standards, which will effectively promote the scale and standardization of the industry. SAIC-GM-Wuling has made good achievements in participating in the formulation of local standards, industry standards, national standards, and even international standards, which is worth summarizing. At the same time, The low-temperature mileage retention rate of Hongguang MINIEV has reached the first place in the industry, and it has also solved the only limitation of small pure electric vehicles compared with fuel vehicles.
