Range Energy eTrailer Passes Rigorous Winter Tests, Ready for Fleet Rollout

Key Details Range Energy has successfully completed winter testing of its production-ready eTrailer system at Michigan's Smithers Winter Proving Ground. The testing validated performance across traction control, regenerative braking, thermal management, and vehicle handling in sub-zero conditions. Why It Matters Fleets need confidence that new electric technologies perform reliably year-round. Range's testing results show their 250-kW electrified trailer system maintains stability and control better than conventional trailers on snow and ice, potentially improving winter safety. What Was Tested Engineers put the eTrailer through demanding maneuvers including emergency stops, sharp turns, and rapid lane changes on ice-covered surfaces. Results demonstrated improved stability and smoother handling compared to standard trailers under identical conditions. System Specifications The eTrailer integrates an electric motor, inverter, gearbox, suspension system, and battery packs ranging from 200 kWh to 300 kWh. The system bolts onto standard semi-trailers and provides propulsion assistance while powering onboard trailer systems. Next Steps Successfully completing this second-generation testing program marks a critical transition from prototype development to full commercial deployment. Range is now positioned to scale production as fleets evaluate the technology for year-round operations.
