For new energy vehicles, especially pure electric vehicles, the "extremely cold environment" in Northeast China has always been one of the "forbidden areas" for new energy vehicles. Only vehicles that can maintain a high standard of operation in terms of power, reliability and range under the extreme climatic conditions of -30 can represent the highest level of new energy vehicles. From January 10 to 11, 2024, Yutong new energy light trucks and heavy trucks gathered in the cold region of Northeast China, and relayed to carry out the collective snow trial of new energy commercial vehicles in Harbin and Jinzhou respectively, and completed the extreme cold challenge with excellent results, which not only directly expanded the winter operation territory of new energy commercial vehicles to 46 ° 40 north latitude, but also verified the comprehensive excellent quality of China's new energy commercial vehicles with hard core strength, and also made its benchmark significance in the industry self-evident. 
In particular, Yutong New Energy Light Truck, the country's first forward-developed electric truck, has withstood the extreme cold test of -30 in Northeast China after successfully challenging the extreme heat test of 70 on the surface in Turpan, and has not been compromised in the long-term operation mileage, becoming the first new energy light truck to cross the 100 temperature difference challenge. "Doing what is said is reliable" is the concept that Yutong has always adhered to, and "not using the market as a testing ground" is the principle that Yutong has adhered to for a long time. Yutong is convinced that only in the real natural environment, only in the real operation scenario can the results and data obtained are the most real, the most referential, the most convincing and the most practical. The first to fight against the extreme cold of the north with strength is Yutong new energy light truck. In Harbin in January, the average temperature ranges from -25 to 13, with extreme low temperatures reaching -30 or even lower. Harbin is not only the provincial capital city with the highest latitude in China, but also the coldest city in the world at the same latitude. In the extreme cold performance challenge on January 10, Yutong new energy light truck challenged the extreme challenges of extreme cold start, extreme temperature rise, low temperature charging and extreme cold battery life. 
Since the beginning of the research and development, Yutong light truck is a new generation of pure e-commerce vehicle platform on the forward development and design, in the integrated electric drive axle + integrated battery pack + all-in-one electronic control of the joint blessing, Yutong new energy light truck has a different comprehensive performance advantage from the ordinary "oil to electricity" light truck products. In the early morning of January 10, after more than 12 hours of standing outside overnight, Yutong New Energy Light Truck was like an ice sculpture, shining dazzlingly in the low temperature environment of Harbin's real-time outdoor ambient temperature of -18. As the testers laboriously pulled open the frost-covered cockpit door, everyone present sweated. The temperature of the individual parts of the vehicle was even lower than the ambient temperature at that time. For pure electric vehicles, the activity of the battery decreases at low temperatures, and it is easy to start or even fail to start. The tester twisted the key, and the Yutong light truck was successfully started at one time, and the on-site personnel collectively cheered, which means that the Yutong light truck was not affected by the low temperature in the cold area at all. 
In the early morning of the next day, in Jinzhou Port, the northernmost port in China, the Yutong 422 kWh electric pure electric tractor that had experienced the outdoor water freezing the day before was also successfully launched under the joint witness of cardholders in the live broadcast room! After starting, all the instruments of Yutong new energy heavy truck are displayed normally, and the battery retention rate is 99%, showing super system stability. The success of Yutong's new energy commercial vehicle's extreme cold start is mainly due to Yutong's software and hardware architecture based on the Ruikon E platform and multiple rounds of ultra-low temperature verification of core components in the environmental warehouse, at the same time, the battery intelligent temperature control technology and the intelligent thermal management technology of the whole vehicle also minimize the impact of the external low temperature environment on the battery energy, so as to ensure its success in the next start under extremely cold conditions. 
In the challenge of rapid heating, the cab temperature of Yutong light truck rose from -17 to 25 in only 8 minutes, and the cab temperature of Yutong heavy truck rose from -19 to 23 in 10 minutes, which fully reflects the optimal heating and comfort brought by intelligent automatic constant temperature air conditioning, and the one-key defrost and defogging function also ensures the safety of driving. Affected by the extremely cold and low temperature environment, the battery pack is prone to capacity loss and charging attenuation, causing energy replenishment anxiety. In the challenge of low-temperature charging, based on the industry's unique battery intelligent temperature control technology and vehicle intelligent thermal management technology and reservation heating technology, under the supervision of on-site personnel, Yutong light truck uses 160kw public charging pile, and the power is charged from 20% to 80% in only 37 minutes and 47 seconds, which is more than 30% higher than the industry's heating rate. Extreme cold endurance is the ultimate challenge to the overall performance of new energy commercial vehicles. In the challenge of "extreme cold endurance", Yutong light truck is based on the exclusive technology platform of Ruikon E electric and the dual technology blessing of T-POWER super electric chain, in the extremely cold environment of Harbin-18, starting from the state of plain car and standard load, passing through urban roads, elevated, national highways and other road conditions, with a total mileage of 105 kilometers and a maximum speed of 85km h, and finally achieved a one-kilowatt-hour electric battery life of 318 km. After passing the four extreme tests, Yutong light truck drove to Chagan Lake to participate in the transportation of fresh fish caught in winter and completed the task excellently. 
Yutong pure electric tractor is involved in the whole process of coal transportation scene. The vehicle traveled to Jinzhou China Power Investment Port to load a full 30 tons of coal and send it to Datang Power Plant and then return to the starting point, the whole journey is 139 kilometers, the power consumption is 177 kWh, and the power consumption per kilometer is only 127 degrees, this achievement can be described as industry-leading. Winter coal transfer is related to people's livelihood, in the Northeast a heating cycle of the use of 10,000 tons of coal in the background, heavy truck transportation can be said to have contributed an important force. 
The real operation scenarios and real operation data not only prove the high reliability of Yutong new energy trucks operating in low temperature environments, but also demonstrate the high adaptability of the vehicles to harsh and complex working conditions. Under the joint witness of the witnesses of the China Automotive Brothers and the audience in the live broadcast room, this series of achievements has become the best response to the extreme cold in the north. Breaking the pain points of the industry with technology The northern region of China mainly refers to the area north of the Qinling-Huaihe River line, and the east of the Daxing'an Mountains and Wusheling Mountains, with an area of about 21310,000 square kilometers, accounting for about 22 of the country's total land area2%。Winter temperatures in the northern regions are usually around -10 0 degrees. In recent years, due to the rapid development of new energy commercial vehicle technology, the penetration rate of pure electric vehicles has been increasing nationwide. However, due to the extreme cold and low temperature environment, pure electric vehicles are affected by multiple factors such as reduced battery activity, serious energy consumption of warm air, low energy efficiency, winter road conditions and increased viscosity of rear axle lubricating oil, resulting in a significant reduction in endurance and restricting the normal use of the vehicle to a certain extent. Based on the group's R&D experience of 180,000 new energy commercial vehicles, 36 billion kilometers of actual road spectrum data collection, based on the needs of various scenarios and working conditions of commercial vehicle operations, and based on the technology support of a new generation of intelligent control e electric exclusive technology platform, the vehicle can not only operate reliably in the -35 45 environment through a number of energy-saving measures such as vehicle intelligent thermal management technology, enhanced regenerative auxiliary energy system, high-efficiency and lightweight integrated electric drive axle, and high-efficiency drive integrated motor. It also has a more economical ultra-long battery life, which is more than 10% longer than the industry mileage under the same working conditions and the same power conditions. It can be said that what Yutong has proved in a series of challenges under extremely cold conditions is not only the courage and strength of "stepping on the ice and controlling the snow and fighting the extreme cold", but also the profound accumulation in the field of new energy technology for many years, the expansion of the performance limit and technical boundaries of China's new energy commercial vehicles, the strength verification of China's new energy commercial vehicle technology and quality, and the brand confidence that will win every battle forged on top of it. 
The hottest city this winter is none other than "Erbin"; As the northernmost port in China, Jinzhou Port is also becoming a bridgehead for the new land-sea corridor in Northeast China. The new quality productivity driven by scientific and technological innovation is not only the driving force for the comprehensive revitalization of Northeast China, but also a powerful driving force for the high-quality development of China's new energy commercial vehicles. The success of Yutong's new energy commercial vehicle in the extreme challenge of "stepping on the ice and controlling the snow and fighting the extreme cold" has once again improved the industry standard for the comprehensive performance of new energy commercial vehicles in terms of low temperature adaptability, reliability, and power, bringing users a more commercial, more durable, and better operating experience, and will also lead the overall progress of China's new energy commercial vehicle technology. Of course, what is more important than challenging the limit is to go together with customers and work together for a win-win situation.
