ELECTRICALLY POWERED TRAILER SYSTEM WITH REGENERATIVE BRAKING

An electric trailer with regenerative braking is adaptive to both EV and ICE tractors, extending towing range of such vehicles, coordinating with performance characteristics of a tractor for maximum tractor-trailer efficiency. Differential electrical control of wheel drives provides enhanced performance safety and driving control. Embodiments optimize performance using real-time road conditions and terrain information. The trailer provides fail-safe operation in the event of system malfunction.
