On January 28, 2026, the "Wanli Fuling · Ouman Galaxy Global Value Appreciation Tour (Electric Vehicle Segment)" in the cold region special line concluded successfully under the witness of the on-site guests, the testing team, the drivers, and the participating truck owners. This cold region expedition saw the Ouman Galaxy 9 and 5M electric heavy trucks complete their journey with the goal of "real routes, full-scenario trials, and user 
deep participation". It lasted for 13 days, covering a total distance of 2030 kilometers. Starting from Changchun, it passed through Baishan, Shenyang, Huludao, Tangshan, and finally arrived in Tianjin, traversing 9 major logistics cities. Throughout the entire journey, they faced extreme low temperatures of -35℃, successively overcoming icy roads, continuous steep slopes and sharp turns at Shanhaiguan, non-paved sections in mining areas, and high humidity corrosion in steel mills, completing a comprehensive and rigorous test of the Ouman Galaxy electric heavy trucks.
Multidimensional hardcore performance, proven through actual combat. Demonstrates all-round strength.
Transportation in the cold regions of the north has always been constrained by issues such as low-temperature endurance, energy replenishment efficiency, and safety compatibility. This expedition is not a single-site performance test, but a comprehensive verification of the cross-regional and all-scenario operation capabilities of pure electric trucks. The Eman Galaxy pure electric truck, leveraging its three core advantages of cold-region adaptation, endurance and energy replenishment, and all-scenario tolerance, has delivered an outstanding practical performance report.
Wide temperature range compatibility, balancing comfort and energy efficiency
Starting from Changchun, the convoy immediately entered the -30℃ extremely cold core area. Throughout the journey, it endured multiple rounds of outdoor storage and alternating day-night temperature differences, facing extreme tests. Whether it was the low-temperature cold start in the Changchun urban area or the continuous severe cold driving along the way from Baishan to Shenyang, all these posed extremely demanding requirements for the vehicle's low-temperature adaptability. It was precisely on this core route that runs through the extreme cold zone that the ultra-wide temperature range adaptability of the OMMAN GALAXY all-electric heavy truck was fully verified.
The Ouman Galaxy all-electric heavy truck, equipped with the intelligent heating Core heating system, successfully withstood continuous low temperatures of -30℃, achieving stable charging and discharging within an extremely wide temperature range of -40℃ to 60℃. After being left outdoors at night, it can be smoothly started with just one click, without any delay in startup or functional limitations. This breaks the constraint of low temperatures on the startup of all-electric heavy trucks. In the northern cold regions, the exclusive intelligent heating Core heating system can exert dual efforts, taking into account both the comfort of the cabin and operational economy: the 4kW independent cabin air heating system controls fuel consumption at 0-0.5L per hour. In an external environment of -19℃, it can raise the cabin temperature from -1.3℃ to the comfortable range in less than ten minutes. Combined with the industry-leading rapid 
cooling high-pressure electronic fan, the operating noise is reduced by 8%. The 15kW intelligent adjustable diesel liquid heater can adaptively adjust power within the range of 3.5kW - 15kW, precisely maintaining the battery temperature, helping to increase the range by 15% and balancing the cabin warmth and range capacity.
Optimal range and charging performance - Say goodbye to range anxiety in cold regions
The core sections of the intercity trunk lines for this cold-region expedition, from Shenyang to Huludao, Huludao to Tangshan, and finally to Tianjin, all feature long-distance trunk transportation as the main scenario. They need to deal with complex road conditions such as continuous low temperatures and ice and snow coverage on some sections, as well as meet the long-range transportation needs across cities. This has put the vehicles' range and charging capabilities to the test in a real-world setting.
Regarding the most concerned issues of range and charging for pure electric transportation in cold regions, the Oumann Galaxy all-electric heavy truck has provided an efficient solution. The vehicle is equipped with a 600kWh large-capacity battery version. Under the strict conditions of continuous heating, icy roads, steep slopes and sharp turns, etc., alternating in complex working environments, this battery version can meet the single-trip transportation needs of long-distance routes in northern cold regions. In terms of charging efficiency, the vehicle is equipped with a dual-charger 600A fast charging system (optional three-charger 900A ultra-fast charging), which provides efficient and stable charging; at the same time, it supports more than 15 different power combination schemes, which can flexibly adapt to different power and types of charging facilities along the route, significantly improving the flexibility of route planning and eliminating concerns about charging in cold regions for long-distance transportation.
Comprehensive scene tolerance builds a solid defense line for safe operation
On the entire route from Changchun to Tianjin, a variety of extreme scenarios are covered. From the perilous mountain passes with continuous steep slopes and sharp turns in Shanhaiguan, to the unpaved and bumpy sections in the mining area of Huludao, to the harsh working environment with high humidity and corrosion and water spraying for dust suppression at the steel mill in Tangshan, as well as the complex operation areas at the ports of Shenyang and Tianjin, the strict tests of different scenarios alternate and accumulate, comprehensively testing the vehicle's protection, durability and handling performance. This also enables the full-scenario adaptability to be demonstrated in actual combat.
The Ouman Galaxy all-electric heavy truck has strengthened the body and battery protection frame. The seismic resistance indicators of key components are three times better than the national standard. The entire vehicle meets the IP68 high-level waterproof and dustproof standard. It passed a 480-hour salt spray corrosion test. In environments such as densely populated mining areas, steel mills with high humidity corrosion, and sections with continuous water spraying in ports, the core components were free from rust, leakage, and malfunctions. Facing continuous uphill and downhill sections in Shanhaiguan, the vehicle has abundant linear power output for climbing. During downhill, the energy recovery and braking systems work together, providing uniform and controllable braking force, and the steering is precise without any slackness. When driving on non-paved and bumpy roads in the mining area, the reinforced chassis and body can stably withstand continuous bumps. The high-level sealing system effectively prevents dust from entering. Continuous operation is without loosening or abnormal sounds, demonstrating stronger adaptability to various scenarios.
The "Ice and Snow Road" provides effective protection against the cold, and its extreme cold endurance capabilities are a testament to its strength! This 13-day, 2,030-kilometer expedition in the cold region not only completed a comprehensive practical test of the Ouman Galaxy all-electric heavy truck in extreme cold environments and complex road conditions, but also solved the core problems that have long constrained pure electric transportation in northern cold regions, promoting the transition of new energy heavy trucks from "laboratory testing" to "real-world application", and writing a practical and substantial chapter for the development of China's high-end all-electric heavy trucks.
