SERES Power Launches Innovative Range Extender System at IAA MOBILITY 2025

On September 9, 2025, SERES Power officially debuted its next-generation SERES Super Range-Extender System at the highly anticipated IAA MOBILITY 2025 exhibition. This launch highlighted several groundbreaking technologies, including high-performance engine advancements and the latest in electric power distribution systems.

The event drew over 60 representatives from revered firms such as AVL, Bosch, Mahle, Schaeffler, Valeo, Stellantis, Mubea, Infineon, and more, alongside global media representatives. SERES aims to foster ongoing collaborations with supply chain partners to develop safer, smarter, and more comfortable transportation solutions worldwide.

Innovative Architecture and Control Technologies

The new range-extending system is built on what's known as the "Saiyi (C2E) Range-Extender Architecture," combined with the advanced "RoboREX Intelligent Control Technology." This sophisticated design boasts three notable benefits: silent operation, high integration levels, and outstanding performance. The C2E architecture implements an integrated design concept that promotes complete synergy between the engine, powertrain, control systems, and structural components, ensuring maximum compactness and cost control. Meanwhile, the RoboREX solution transforms the range-extending module from a passive to an active mode, enabling smart energy management.

As a result, energy efficiency has been enhanced by 15%, noise levels lowered by an impressive 90%, with actual performance achieving 3.65 kWh/l, and maximum thermal efficiency reaching an astounding 44.8%. These figures highlight SERES Power’s leadership in the production of range-extending devices, setting a new benchmark in the industry.

Electric Drive System Enhancements

The distributed electric drive system heralds a significant upgrade to driving experiences, guaranteeing both safety and comfort. SERES firmly believes that safety represents the highest form of luxury. Ongoing developments include distributed drive systems with configured architectures featuring two, three, and four motors to meet energy needs across various vehicle classes.

The survey indicates that vehicles equipped with this range-extending technology have become the preferred choice among luxury consumers, providing a comfortable and efficient travel model, allaying concerns about range limits or charging station accessibility.
