Range Energy has completed a multi-year winter testing program validating the performance of its production-ready eTrailer system, marking a key step toward commercial deployment of its trailer electrification platform.
The latest round of testing was conducted at the Smithers Winter Proving Ground in Michigan’s Upper Peninsula, where the system was evaluated in sub-zero temperatures and low-traction conditions designed to simulate real-world winter operations.
Engineers assessed traction control, regenerative braking, thermal management, and overall vehicle handling through demanding maneuvers such as emergency stops, sharp turns, and rapid lane changes on snow- and ice-covered roads.
Results showed the electrified trailer system improved stability and control compared to conventional trailers, which were more prone to losing traction under the same conditions.
“Completing this second testing program on a production-ready system is a critical milestone for Range as it shows our system can maintain top performance in real-world operations,” said Collin MacGregor, vice president of product, safety, and systems at Range Energy.
The system integrates a 250-kW electric motor, inverter, gearbox, regenerative braking, and onboard battery packs ranging from 200 kWh to 300 kWh, delivering propulsion assistance to the tractor while also powering trailer systems. Installed directly onto standard semi-trailers, the platform is designed to operate without requiring changes to driver workflows or charging infrastructure.
Range says the technology has already been demonstrated in fleet operations across the U.S. and Canada, where it has delivered 50% to 70% improvements in fuel economy and enabled the elimination of diesel use for refrigerated units.
With winter validation complete, the company is positioning the eTrailer system for scaled manufacturing and broader deployment, emphasizing that consistent performance in extreme weather is a critical requirement for fleet adoption.
