As the wave of new energy sweeps across various regions, the market for new energy heavy-duty trucks is witnessing an increasing number of participants. Traditional heavy-duty truck brands are accelerating their transition to electrification, while newcomers like Weidu, Lingyi, Shenxiang, and Subao are also entering the fray, making the competition in the new energy heavy-duty truck market fierce and dynamic. Unlike the orderly and technologically unified traditional fuel-powered heavy-duty trucks, the new energy heavy-duty truck market is full of uncertainties and variations.
Creating True Value for Users: Great Wall Motors’ Intelligent Electric Drive Axle
Amidst this highly competitive market environment, achieving both “technological breakthroughs and reliability” has become a crucial challenge for the industry. Since its establishment in 2021, Great Wall Motors has embarked on a unique and independent path in the new energy heavy-duty truck sector. Recently, Great Wall Motors has achieved a significant milestone with the mass production of its fully self-developed Intelligent Electric Drive Axle, a testament to its commitment to innovation and creating genuine value for its customers.
During a recent media briefing on the “Full Stack Self-Developed Electric Drive Axle,” Tang Ziwei, Dean of the Electrification Research Institute at Great Wall Motors, emphasized, “Great Wall Motors is not adept at price wars; our goal is to create value in our products and pass that value on to our customers.” The mass production of the Intelligent Electric Drive Axle exemplifies this philosophy.
Overcoming Technical Challenges: Mastering Core Technologies
In the field of new energy heavy-duty trucks, the integrated development of electric drive axles has become the recognized future direction. Manufacturers need to overcome various technical barriers to meet the accelerating industry transformation. The mass-produced Intelligent Electric Drive Axle from Great Wall Motors features a self-developed dual oil-cooled flat-wire motor with an efficiency of 97%. It boasts characteristics such as uninterrupted shifting during climbing and consistent power output. Intelligent algorithms in the integrated power domain controller enable efficient power distribution between the two motors based on the transportation scenario, optimizing shift strategies to reduce energy consumption.
This advanced algorithm acts as the “brain” of the vehicle, addressing foundational performance and upgrade potential. With a sufficiently advanced algorithm, the vehicle’s performance ceiling remains high. In addition to performance enhancements, the Intelligent Electric Drive Axle adheres to stringent technical standards, distinguishing it from many other electric drive axles on the market. Each technological advancement aligns perfectly with user needs, allowing customers to experience superior performance at competitive prices. Addressing range anxiety, a common concern for new energy heavy-duty truck users, Great Wall Motors adopts a combination of large-capacity batteries and dual-motor electric drive axles, crucial for overcoming limitations and enabling long-haul transportation.
The new fully self-developed electric drive axle integrates a 4-speed AMT gearbox, achieving a lightweight design that is 100-150 kilograms lighter than current market competitors. It offers strong resistance to vibration and shock, minimal energy loss, and high transmission efficiency. Designed for an industry-leading lifespan of 1.8 million kilometers, the axle has undergone component-level, system-level, and vehicle-level testing to ensure durability and reliability, supporting maximum vehicle speeds of 120 km/h and climbing gradients exceeding 30%.
The highly integrated design of the gearbox and axle is considered a new-generation golden powertrain. Although Great Wall Motors’ commercial vehicle division is relatively new, its technology-driven approach has inspired confidence in the future of intelligent trucks.
Conclusion
Successful companies riding the waves of innovation typically do so by aligning with technological advancements and meeting user demands. The domestic heavy-duty truck market, characterized by high competition and dual tracks of traditional fuel and new energy vehicles, is becoming increasingly complex with the entry of new players. However, rewriting history is often more intriguing than merely making profits. Although Great Wall Motors’ journey in recent years has been dramatic, its story is far from reaching its climax.
The continued evolution and breakthroughs in Great Wall Motors’ new energy heavy-duty trucks exemplify how technology and innovation can drive market success and redefine industry standards.
