Abstract: A power management and selection system for a class 8 tractor trailer, directs excess solar and vehicular charge capacity to an auxiliary load by measuring available charge capacity from a reefer power system including a reefer battery, solar panel and charge controller for moderating solar power to the reefer batter, and measuring available charge capacity from a cab vehicle power system including a propulsion system battery and alternator. Charge logic, in a selector configured for switching charge capacity to the auxiliary load, determines which of the reefer power system and cab vehicle power system has the most potential excess charge capacity, and directs the determined excess charge capacity to the auxiliary load, while the measured available charge capacity remains sufficient for powering the respective reefer power system or cab vehicle power system.

Abstract: A motion detection and interlock mechanism prevents unintended drive-off of a trailer still connected to a charging source, which could cause damage and/or injury if continued unimpeded. Trailer power for electrical components is a high voltage AC connection, typically between 277-480 VAC. Forced disconnection of an engaged plug could damage the plug and receptacle, leave electrical conductive members unprotected, and cause a short circuit. Electrical connections to trailers may be made for powering electric TRUs (Transport Refrigeration Units) for refrigerated loads, and for charging a storage battery for powering the TRU over the road or even the tractor itself in the case of a hybrid/electric tractor. In configurations herein, an e-axle is provided on the trailer suspension, such that a driveaway prevention circuit reverse biases the wheels to prevent movement of the trailer while engaged with a charging outlet.

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.
