From the roaring era of traditional fuel to the quiet era of intelligent electric drive, Seres Power BU has led an amazing power revolution in the industry through continuous independent innovation. From the "Heart of China" Top Ten Engines to redefining the super range-extender system, Seres Power BU, as a technical breakthrough-maker, has forged a unique path amid the once-in-a-century automotive industry transformation.
Deep reserves in traditional power domain
When the first batch of engines was prototyped in Zhangjiawan, no one anticipated that this company would become a leader in new energy vehicle power technology two decades later. It was through long-term cultivation and persistent innovation in the traditional power field that Seres Power BU laid a solid foundation in technology and manufacturing, successively breaking through the major production milestones of one million and four million engines. During this period, Seres Power BU developed full-scenario fuel power solutions for a wide range of vehicle models, accumulating valuable R & D experience, precision manufacturing processes, and a large supply chain system, setting the stage for its subsequent technological upgrading.
Super range-extender technology emerges as a game-changer
In 2019, Seres Power BU first proposed the concept of "oil-to-electric conversion rate," re-establishing the efficiency benchmark for range-extender technology. Based on this, it launched the first generation super range-extender system, achieving an oil-to-electric conversion rate of 2.7 kWh/L. Technological progress has never ceased. Since starting pre-research in 2016, Seres Power BU has completed five systematic iterative upgrades, each step precisely targeting users' core needs: The first generation range-extender system in 2019 focused on solving basic power-holding capability and reliability; The second generation system in 2020 aimed to optimize the all-scenario pure electric driving experience and enhance the smoothness of range-extender engagement; The third generation system in 2021 prioritized efficiency, boosting the oil-to-electric conversion rate to 3.2 kWh/L; The fourth generation system in 2023 focused on improving NVH performance and significantly enhancing cabin quietness; Until in 2025, the new generation super range-extender system achieved a breakthrough, adopting the self-developed SERES range-extender architecture and RoboRex intelligent control technology. It achieved three leading advantages: quietness with imperceptible operation, high integration, and high efficiency. It revolutionarily changed the working mode of the range-extender and realized intelligent active energy management. It reduced combined fuel consumption by 15%, lowered noise perception frequency by 90%, enabled 1 liter of fuel to generate over 3.6 kWh of electricity, and achieved the industry's highest mass-production thermal efficiency of 44%.
Seres Power BU boasts a R&D team composed of renowned experts in the new energy vehicle intelligence and powertrain fields. It has obtained over 200 invention patents and more than 1,800 self-owned intellectual property patents. In the intelligent manufacturing field, Seres Power BU's factory is equipped with world-class processing, testing equipment, and advanced information management systems. It can monitor in real-time operating conditions of quality, processes, equipment, and production, ensuring product reliability. By optimizing production processes and reducing defect rates, it has significantly improved manufacturing efficiency and lowered overall costs, providing a solid guarantee for the large-scale, high-quality, and cost-effective implementation of super range-extender technology.
