The granted patent covers a range-extending hybrid transmission system that decouples the engine, generator-motor, and drive wheels through a multi-clutch and multi-shaft architecture, allowing all power sources to contribute concurrently or independently — expanding vehicle range performance while reducing mechanical complexity.
The newly patented transmission architecture is expected to be incorporated into the broader AIHER system under development for future generations of FX models, helping overcome the weaknesses of conventional hybrid and plug-in hybrid systems and making it particularly suited to cold-weather regions.
LOS ANGELES, June 26, 2026--(BUSINESS WIRE)--Faraday Future Intelligent Electric Inc. (NASDAQ: FFAI) ("Faraday Future", "FF" or the "Company"), a California-based global Embodied AI (EAI) ecosystem company, today announced that the U.S. Patent and Trademark Office has granted U.S. Patent No. 12,630,004, titled "Range-Extending Hybrid Transmission System," to its subsidiary Future AIHER AI Hybrid Extended-Range Electric Powertrain System Inc. ("Future AIHER"). The patent, issued in May 2026 from an application filed last June, contains 13 claims, marking a key milestone in the Company's effort to establish a leadership position in hybrid electric powertrain innovation. The present disclosure relates to a range-extending hybrid transmission system for a vehicle, and more particularly, to a hybrid transmission system configured to decouple the engine, generator-motor, and drive wheels to provide multiple drive modes.
Existing plug-in hybrid systems still suffer from flow power output response, insufficient performance, poor driving control, and high overall vehicle costs. Additionally, the complex mechanical structures in conventional systems can negatively impact vehicle handling, reliability, and overall driving experience. The present FF patent disclosure addresses these challenges by providing a simplified hybrid transmission system that decouples the engine, generator-motor, and drive wheels, allowing all power sources to participate in the drive at the same time. This approach enables strong range extension with weak hybridization, improving power efficiency and performance while reducing the overall complexity of the powertrain.
The granted patent (U.S. Patent No. 12,630,004) covers a range-extending hybrid transmission system that includes a first rotary power source, a generator-motor, a differential, and driving wheels. The system includes a first shaft extending from the rotary power source and a first clutch disposed on the first shaft. A second clutch is spaced apart from the first clutch. A generator-motor is connected to the first shaft or to a second shaft that is mechanically connected to the first shaft and/or the second clutch. A third shaft connected to the differential is mechanically linked to the first shaft and/or the second clutch. This configuration enables the decoupling of the engine, generator-motor, and drive wheels, allowing all power sources to contribute concurrently or independently.
