——Reshaping global urban public transportation with zero-emission genes
I. Technology accumulation: 20 years of independent innovation, defining new standards for electric buses
As a pioneer of new energy vehicles in China, Dongfeng Motor took the lead in laying out the pure electric technology route. After more than 20 years of technology iteration, Dongfeng Special Vehicles has built a full-chain independent technology system for pure electric buses based on the group’s core breakthroughs in the field of “three electrics” (batteries, motors, and electronic controls).
1. Power system innovation: Equipped with high-density solid-state batteries (energy density of 350Wh/kg) and 350kW high-power electric drive platform, the cruising range exceeds 300 kilometers, meeting the needs of all-weather bus operations;
2. Energy efficiency control breakthrough: Through the industry’s first “ten-in-one” electric drive system, the system volume is reduced by 25%, the weight is reduced by 20%, and the CLTC comprehensive energy efficiency reaches 89%, which greatly reduces the energy consumption per unit mileage;
3. Safety and reliability verification: The core modules such as the vehicle controller and battery management system are 100% independently developed, and “zero fault” operation is achieved in major scenarios such as Olympic security.
II. Product analysis: The hard-core gene of Dongfeng Chaolong pure electric buses
Taking the star model Dongfeng Chaolong EQ series pure electric buses as an example, its design directly hits the pain points of urban public transportation.
1. Space design: The low-floor widened body compartment layout improves passenger efficiency by 30%, and barrier-free facilities facilitate the entry and exit of people with disabilities.
2. Power performance: The permanent magnet motor is equipped with intelligent electronic control, which can achieve 0-50km/h acceleration within 15 seconds and a climbing grade of up to 17%.
3. Environmental adaptability: The battery temperature control system reduces the heat dissipation of the whole vehicle by 30℃ to 50℃, and the endurance attenuation rate in high temperature and cold areas is less than 15%.
4. Intelligent experience: Multi-sensor fusion + vehicle networking system, real-time monitoring of energy consumption, remote fault diagnosis.
This model adopts a streamlined appearance and low-noise motor. The cabin is equipped with intelligent air conditioning and multimedia interactive screen, which deeply integrates “riding comfort” and “driving controllability” to completely eliminate the dizziness caused by electric vehicle acceleration.
III. Scenario application: Solving the pain points of global urban transportation
Dongfeng pure electric buses have formed a multi-scenario solution matrix:
1. Urban public transportation system
(1) Typical case: Shiyan Public Transport Group has put the entire line into operation, achieving 100% replacement of traditional natural gas vehicles;
(2) Economic verification: Each vehicle reduces carbon dioxide emissions by 40 tons per year, and the operating cost is 70% lower than that of fuel vehicles.
2. Special environment transportation
(1) High altitude areas: adaptive adjustment of motor torque, stable operation in mountainous cities such as Linzhi, Tibet;
(2) Extreme climate areas: antifreeze battery pack + anti-skid driving mode, successfully applied to icy and snowy roads in Northeast China.
3. Customized derivative models
Based on the same platform, special models such as nucleic acid detection vehicles and mobile CT vehicles are developed to expand the boundaries of public service electrification.
IV. Global adaptation: technology output drives overseas market expansion
In response to the core needs of the foreign trade market, Dongfeng Special Automobile provides three major technical cooperation paths:
1. Energy solution compatibility: support flexible configuration of lithium iron phosphate/ternary lithium batteries to adapt to differentiated environments such as high temperatures in Southeast Asia and low temperatures in Northern Europe;
2. Infrastructure coordination solution: develop a “fast charging + battery replacement” dual-mode system, which can replenish 80% of the power in 30 minutes of fast charging to solve the problem of insufficient charging network;
3. Open intelligent interface: reserve the Internet of Vehicles API interface, which can be connected to ecological platforms such as Google/Huawei to meet the data interoperability needs of smart cities.
V.Conclusion: Reshaping the Green Travel Gene with Chinese Technology
“Electric buses are not only a means of transportation, but also a mobile node for sustainable urban development.” – The declaration of the Dongfeng technical team at the 2025 World Transport Forum is the best interpretation of Dongfeng Special Automobile’s technical concept. Dongfeng Special Automobile is becoming a leading global automobile manufacturer and operator.
