Range Energy announced it has completed vehicle dynamics and stability testing of its eTrailer system at the Transportation Research Center (TRC), saying that it validated the safety and performance of its trailer electrification technology under aggressive, real-world conditions.
Following winter testing earlier in March, which focused on operations in subzero temperatures, the latest phase this summer focused on dry and wet pavement performance, with over 400 dynamic maneuvers conducted at TRC’s facility, the company said in a news release. These included J-turns, double lane changes, as well as straight-line acceleration and braking tests to evaluate traction control of the eAxle.
To enable the rigorous testing, Range said that it equipped the trailer with outriggers and anti-jackknife cables — devices that prevent full tip-over in extreme conditions.
According to the company, the Range eTrailer’s system engaged regenerative braking earlier than conventional trailers during critical maneuvers, reducing lateral forces by up to 25% and enabling 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 at Range Energy. “From fine-tuning traction control and delivering precise stability interventions through regenerative braking, to ensuring seamless compatibility with today’s truck brake systems, every element is designed to perform when it matters most.”
Range says its eTrailer integrates with diesel and electric trucks without requiring modification to the tow vehicle.
