In the extremely cold ice plain of Mohe at -35℃, the severe cold prevails and the environment is extremely harsh. This is not only a natural testing ground for the extreme environmental performance of heavy trucks, but also the ultimate test for the cold-weather operation capabilities of new energy heavy trucks. This winter, the R&D team of Foton Motors, along with the Galaxy 9, Galaxy 5M pure electric heavy trucks and Galaxy 5M PHEV hybrid 
heavy trucks, completed comprehensive extreme cold performance tests in Mohe. Through rigorous verification, they shattered the pain points of cold-weather transportation for new energy heavy trucks, and tailored a full-scenario transportation solution for logistics practitioners in high-altitude areas that is resistant to extreme cold, efficient without compromise, and safe with guarantee. This demonstrates the benchmark confidence and core strength of China's heavy truck new energy transformation.
Pure electric hard verification test
Overcoming operational challenges in cold regions
In the winter trunk transportation in the north, problems such as low-temperature power attenuation, reduced range, inefficient charging, and delayed heating and defrosting have long hindered the popularization and implementation of pure electric heavy trucks. Especially in low-temperature environments, the power stability directly affects the timeliness and profitability of trunk transportation. At an extreme -35℃ working
condition, both the Foton Daimler Ouman Galaxy 9 and Galaxy 5M pure electric heavy trucks start with an initial power of 200kW. They do not require long-term idling preheating and can obtain sufficient power after startup, easily handling scenarios such as accelerating at the early hours of the northern expressway entrances and climbing slopes in mountainous areas that require instantaneous power support. Among them, the Galaxy 9 pure electric heavy truck can climb to its maximum output power within 30 minutes, and the Galaxy 5M pure electric heavy truck reaches its peak power after 40 minutes. During continuous driving, the power output remains stable without attenuation, effectively avoiding speed decline due to insufficient power and ensuring that the timeliness of trunk transportation in cold regions is not affected.
During winter transportation, the safety of the driver's field of vision and the comfort of the passengers directly affect the driving safety and physical health of the truck drivers. Actual tests have shown that the Oumann Galaxy all-electric heavy truck, when left outdoors in a -25℃ environment overnight with the glass covered in frost, can clear the frost and achieve clear vision in just 10 minutes with the Galaxy 5M pure electric model, and the Galaxy 9 pure electric model also takes only 12 minutes to remove the frost. This eliminates the safety risks caused by frost and fog blocking the view at the source. Moreover, the intelligent heating Core system installed in the Oumann Galaxy all-electric heavy truck can raise the temperature of the driver's and passenger's feet to the 15℃ human-comfortable temperature within 11 minutes after starting at -30℃ low temperature, which not only alleviates driving fatigue but also effectively prevents occupational health problems such as low-temperature frostbite and joint pain.
"Slow charging in winter and reduced range" are the biggest obstacles for the promotion of pure electric trucks in cold regions, and they are also the most worrying usage problems for truck drivers. The Oumann Galaxy pure electric truck adopts a 600A dual-chargers design (with the option of a 900A triple-chargers), and its charging efficiency in extremely cold environments is outstanding. After the vehicle warms up during driving, it can quickly replenish the battery power. Combined with the vehicle's overall range of nearly 400 kilometers, a quick charge can replenish approximately 240 kilometers of range, making pure electric transportation in cold regions more convenient and efficient.
Hybrid efficiency adaptation
Empowering the transportation of coal sand in cold regions
For the full-load transportation scenarios of coal and sandstone materials in cold regions, Foton Eman Galaxy 5M PHEV hybrid heavy truck precisely addresses the three core pain points of "difficult starting, high fuel consumption, and slow charging". During this extreme cold test, the Eman Galaxy 5M PHEV hybrid heavy truck, after being left outdoors to stand for the entire night at -35℃, could start instantly with just one button press, and the engine speed quickly climbed and remained stable. This outstanding performance is attributed to the extreme cold adaptation optimization of the vehicle's core components and the exclusive low-temperature start calibration of the Fokang hybrid engine, allowing drivers to start the vehicle in winter and ensure timely transportation departures, seizing the operational opportunity in the peak winter transportation season.
The transportation of coal and sandstone materials is mostly in full-load conditions, and often passes through complex sections such as mountainous areas and mining zones, which impose extremely high requirements on the vehicle's power output and driving stability. At the same time, the increase in fuel consumption in winter also increases the operating costs for drivers. The Oumann Galaxy 5M PHEV hybrid heavy truck has a maximum combined horsepower of up to 780, which is sufficient to handle heavy-load scenarios such as full-load climbing and overtaking. Combined with the fine adjustment of the AMT transmission, the driving process is smooth without bumps, which better alleviates the driver's driving fatigue. In addition, the vehicle is equipped with an autonomous HCU intelligent algorithm, which can precisely schedule the distribution of oil and electricity based on real-time load and road conditions, achieving the optimal power output. When driving at 80 km/h on a highway with no load or a loaded state, it can 
switch to pure electric mode. When cruising at high speed, it switches to the hybrid electric assistance mode. When going downhill or braking, it activates the efficient energy recovery function, converting potential energy and kinetic energy into electrical energy for storage, forming an "uphill power generation, downhill charging" energy cycle, which is highly suitable for the working characteristics of "multi-slope sections" in coal and sandstone material transportation.
Furthermore, regarding the charging issue that many customers are concerned about, the Ouman Galaxy 5M PHEV hybrid heavy truck has also easily solved this problem. During the extreme cold test in Mohe, it only took 40 minutes to fully charge the battery. The charging efficiency of this vehicle far exceeds that of similar models in the industry, effectively resolving the pain points of "slow charging and difficult charging" for hybrid heavy trucks in cold regions, achieving "fast charging and long operation time", and maximizing transportation efficiency.
Overall, the Foton Ouman Galaxy heavy truck successfully completed the extreme cold test in Mohe (-35℃) and not only set a performance benchmark for new energy heavy trucks in cold regions in the industry, but also demonstrated Foton's responsibility and commitment to deeply understanding user needs and solving industry pain points through technological innovation. In the future, Foton Ouman will continue to strive, providing reliable solutions across the entire temperature range and in all scenarios for cold region logistics transportation, accompanying every driver to calmly face the cold conditions and move forward efficiently, and writing a new chapter in the transformation of China's heavy truck new energy.
