Faced with the accelerating transformation of commercial vehicles to low-carbon, electric heavy-duty trucks have truly opened the prelude to the green transformation of heavy-duty trucks with the advantage of "zero emissions". Especially in the field of short haul transportation, the batch application mode launched by steel mills, coal mines, cement, ports and other enterprises has greatly promoted the development of new energy heavy trucks. However, with the continuous expansion of application scenarios, electric heavy-duty trucks still face challenges such as insufficient range, low efficiency, insufficient power, and unstable reliability. These pain points are directly related to whether electric heavy-duty trucks can win favor in the medium to long distance logistics market, which focuses more on load and efficiency.
Only innovation breaks through internal competition, and only technology opens up new opportunities. As the industry leader in China's earliest research and development of new energy heavy trucks and their practical application in operating conditions, Ouman New Energy Heavy Truck has undergone multiple technological iterations to launch Ouman Smart Blue bottom swapping heavy trucks. With new technology advancements, it creates more energy-saving, efficient, safe, reliable, and intelligent bottom swapping products. With customized bottom swapping solutions for the entire scene, it helps to maximize customer benefits.
More energy-efficient: Under comprehensive working conditions, the overall energy consumption of the vehicle is optimized by 9% -15%, and the range is longer
As a means of production, the energy consumption of new energy heavy-duty trucks is directly related to the operating costs of customers, and lower energy consumption means longer range. Based on this, the Oman Smart Blue bottom replacement heavy-duty truck has been optimized through technology to reduce customer operating costs. For example, the complete vehicle eliminates the transmission shaft, shortens the power transmission path, and improves the efficiency of the electric drive system by 6%. In addition, the entire vehicle can form 8 combined driving modes based on different wheel end torque and power requirements, combined with gear numbers, to meet the complex working conditions of the vehicle, with energy savings exceeding 3%; For the hilly scene, the Ouman Smart Blue bottom battery replacement heavy truck proposes a predictable driving algorithm based on high-precision maps, actively adjusting the vehicle speed and battery SOC, fully utilizing the potential energy of the ramp for energy recovery, saving 4% -6% energy, and optimizing the overall vehicle energy consumption by 9% -15%.
More efficient: the driving efficiency of the entire vehicle is improved by more than 6%, ensuring operational efficiency
Whether traditional heavy trucks or new energy heavy trucks, for users, achieving high efficiency through Dora Kuai Pao brings higher attendance rates, which not only meets customer operational needs, but also directly affects customer profits. Therefore, the electric drive axle module used in the bottom of the Ouman Smart Blue traction system integrates the electromechanical coupling gearbox with the middle and rear axles, reducing the weight of the power system by 500kg and achieving more traction. In addition, combined with new technologies such as silicon carbide modules, high-speed flat wire oil cooled motors, and dog gear shifting, the drive system is more efficient; And according to different vehicle loads, there are as many as 8 driving modes for the entire vehicle based on the combination of single axle double axle drive and drive axle gear. The electric drive system is fully upgraded, and the driving efficiency is improved by more than 6%.
Safer: Synchronous optimization of active and passive safety, reliable protection of people, vehicles, and goods
Safety has always been the key core of new energy heavy trucks. Faced with potential safety risks, the Ouman Smart Blue bottom replacement heavy card has been optimized for layout, upgraded in materials, and taken measures such as active and passive safety protection to ensure the safety of people, vehicles, and goods. For example, in response to the higher reliability requirements of high-speed operation scenarios, the new product of Ouman's bottom power exchange has achieved independent control of the accessory domain, comfort domain, and power domain, with decoupling of each domain, resulting in higher reliability. In response to the characteristics of high-speed vehicle operation scenarios, the battery pack adopts an integrated die-cast aluminum profile with a thickness of up to 70mm. It has passed 17 mandatory safety inspections for the battery pack at once, resulting in better passive safety; The integrated design of the high-voltage box and battery management system, while monitoring the temperature of the battery cell and the status of the high-voltage fast plug-in in real-time, provides better proactive safety. From battery cells to systems, from passive safety to active safety, ensuring reliable operation of the entire vehicle from multiple dimensions.
More intelligent: Three battery options available, with more flexible battery swapping modes and more suitable scenarios
In the face of customer operation scenarios and electricity demand, the Ouman Smart Blue bottom power exchange traction system can interact with the station of the power exchange station through T-BOX according to different transportation tasks, achieving intelligent power exchange in three electricity consumption modes of 171/342/513kWh, and reducing customer costs. In response to winter driving needs, in the low-temperature environment of the north, the Ouman Smart Blue bottom electric traction inherits the Ouman electric heavy truck cold zone version technology. The industry is the first to use the motor as a heat source and quickly heat the antifreeze to achieve a rapid increase in battery temperature; In the face of ramp scenes, alternate shifting is achieved through the dual axles of the electric drive axle to achieve uninterrupted shifting power and a more comfortable driving experience.
At present, Ouman Zhilan Heavy Truck has covered seven major scenarios of mainstream electric heavy truck applications in China, including steel mills, mining areas, ports, etc. The product line includes traction, self unloading, mixing, sanitation, etc., which can meet the full range of industry and user needs. At the same time, the product has been launched in 14 provinces, regions, and cities in China, and has passed the tests of typical characteristics of China's territory such as extreme cold in the north, high humidity and heat in the coastal areas, and southwestern mountainous areas. The cumulative driving mileage is 26 million kilometers, and the product has been recognized by the market.
Technology driven, leading the future. With the gradual improvement of the new energy heavy-duty truck ecosystem, Ouman Zhilan will continue to solve user pain points through technological innovation, and provide customized bottom swapping solutions that are more energy-efficient, efficient, safe, and intelligent for the entire scene, continuously helping customers reduce costs and increase efficiency, and promoting the positive development of the new energy commercial vehicle industry.
