Range Energy has completed vehicle dynamics and stability testing of its eTrailer system at the Transportation Research Center Inc. (TRC), an independent mobility testing facility in North America.
Watch the real-world testing and results in this video.
The round of testing, conducted this summer, followed winter validation earlier in the year and focused on system behavior during high-dynamic maneuvers, particularly on dry pavement where the risk of trailer rollover increases.
To support safety during aggressive maneuvering, including J-turns and double lane changes, the eTrailer was outfitted with outriggers and anti-jackknife cables. These test configurations enabled engineers to evaluate the system’s response without the risk of a full trailer tip-over.
The traction control performance of the powered axle (eAxle) was assessed under straight-line acceleration and braking scenarios, both on dry and wet surfaces.
The testing campaign included over 400 maneuvers across varied conditions, including multiple tractor configurations, payload levels, and vehicle speeds. The aim was to validate the eTrailer system’s integration with standard truck braking and electronic stability control systems. Particular attention was given to the coordination between regenerative braking and lateral stability management.
One notable result was a reduction in lateral force of up to 25% during critical turns, as the system applied regenerative braking earlier in the maneuver sequence. This preemptive response helped improve vehicle handling and reduce the risk of rollover or loss of control.
The eTrailer system is compatible with diesel and electric Class 8 tractors and does not require modifications to the tow vehicle. Engineering efforts have focused on maintaining system compatibility while introducing active features that improve vehicle dynamics, safety margins, and energy recovery across diverse operational scenarios.
