Abstract
A self contained battery and slide frame houses a pair of trailer axles and an electrical vehicle storage battery secured by parallel slide frame rails adapted for attachment to an underside of a standard tractor trailer (Class 8) trailer frame. The slide frame attaches to an underside of a trailer using perforated frame beams used to vary a position of the wheel/axle assemblies relative to the trailer body and payload. The slide frame rails provide self contained support for a storage battery, e-axle, control electronics and connecting wires for charging and running a vehicle load from the storage battery. Vehicle loads powered by the storage battery include transport refrigeration units (TRUs) and electrical vehicle (EV) tractors.
