What's Happening?
Stellantis, through its FCA US division, has been granted a patent for an electric drive module designed to provide two speeds, a true neutral, and a power take-off (PTO) for electric trucks and SUVs. This innovation addresses a common limitation in current
electric vehicles, which typically use a single fixed gear ratio per motor. The patent, filed by Auburn Hills engineers Tejinder Singh and Neil Jackson, describes a system with a compound planetary gearset, a clutch, and a brake. This setup allows for a '4LO' gear for off-road trails, heavy towing, and vehicle recovery, and a '4HI' gear for efficient on-road driving. The neutral position disconnects the motor from the wheels, enabling flat towing and the use of the PTO for powering external equipment like generators, winches, or machinery. This development aims to bridge the gap between the capabilities of traditional gas-powered work trucks and their electric counterparts.
Why It's Important?
This patent is significant for the U.S. automotive industry, particularly for the electric truck and SUV segments. It signals Stellantis's commitment to enhancing the utility and versatility of electric work vehicles, which could accelerate their adoption in sectors reliant on heavy-duty capabilities. By offering a two-speed transmission and a PTO, Stellantis is directly addressing the needs of truck owners who require sustained high torque for demanding tasks, such as off-roading, towing, and operating auxiliary equipment. This could make electric trucks more competitive with their internal combustion engine counterparts, potentially expanding the market for electric vehicles beyond passenger cars. The ability to power external machinery directly from the electric drivetrain could also open new possibilities for mobile power solutions in various industries, from construction to agriculture, reducing reliance on separate generators and fuel sources.
What's Next?
While a patent does not guarantee immediate product launch, this development suggests Stellantis is actively exploring advanced drivetrain solutions for its future electric truck and SUV lineup, including brands like Ram and Jeep. The patent specifically mentions applications in 'range extender battery electric vehicles' and 'heavy duty truck applications,' indicating potential integration into upcoming models like the Ram 1500 REV and Jeep's range-extended Grand Wagoneer. The company's focus on providing capabilities traditionally found in gas-powered work trucks, such as low-range gearing and PTO, indicates a strategic effort to cater to a broader customer base. Future developments will likely involve further testing and refinement of this technology, with potential announcements regarding its inclusion in specific vehicle models in the coming years. The industry will be watching to see how this innovation translates into tangible products and how it impacts the competitive landscape of electric work vehicles.
Beyond the Headlines
This patent highlights a broader trend in the automotive industry: the electrification of utility and work vehicles. As the U.S. transitions towards electric mobility, manufacturers are challenged to replicate and even improve upon the robust capabilities of traditional internal combustion engine vehicles. The integration of features like a two-speed transmission and a PTO in an electric drivetrain represents a crucial step in this evolution. It underscores the engineering complexity involved in making electric vehicles truly versatile and capable across a wide range of applications. This innovation could also influence regulatory discussions around vehicle capabilities and emissions standards for work vehicles. Furthermore, the ability to use an electric truck as a mobile power source could have significant implications for disaster relief, remote work sites, and off-grid living, fostering new use cases and business models for electric vehicles beyond mere transportation.
