Range Energy completes dynamics testing of eTrailer System

Trailer electrification technology company Range Energy announced the successful completion of vehicle dynamics and stability testing for its eTrailer System at the independent mobility testing facility Transportation Research Center Inc. (TRC). Following its winter testing completed in March 2025, Range’s testing this summer focused on validating system performance, control and safety under dynamic conditions, particularly on dry pavement surfaces that pose an increased risk of trailer rollover.

To safely conduct this testing, Range equipped its trailer with outriggers and anti-jackknife cables — key safety mechanisms that help prevent full tip-over during extreme tests such as J-turns and double lane changes. Range also evaluated traction control of the eAxle in straight-line acceleration and braking. These maneuvers were then repeated on wet test surfaces at TRC’s facility.

According to Range, the testing involved over 400 dynamic maneuvers — including a wide range of speeds, payloads and tractor configurations — to ensure Range’s system integrates seamlessly with standard truck braking and stability systems while maintaining or improving performance in any real-world scenario. Compared to conventional trailers, the Range system intelligently engaged regenerative braking earlier in critical maneuvers, the company said, gently slowing the vehicle and reducing lateral force by up to 25 percent. This allows drivers to complete the same turn at the same speed more safely, avoiding loss of control or rollover.

“Testing under extreme conditions and with aggressive maneuvers is critical to prove the intelligence and reliability of our control systems in real-world conditions,” said Kyle Foley, head of engineering for Range Energy.

He added, “Testing at TRC goes beyond technical validation — it’s about building trust. Because when you’re moving freight, you’re carrying important goods that drive modern life and society forward.”

The eTrailer System is designed to work with a variety of trucks, including diesel and electric semi-trucks, with no modification to the tow vehicle. Range said it significantly enhances the efficiency, safety and vehicle dynamics for fleets in addition to offering a sustainable pathway for commercial trucking operations at large.
