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.

Driveaway prevention for electric trailer charging plug

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.

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.

Solar charging of multiple battery banks

A reefer truck power unit employs a plurality of power sources including roof mounted solar panels, momentum generation, shore power and high capacity storage batteries. The refrigeration system is configured for refrigerating a payload area of the vehicle utilizing power from the power sources, and employs a voltage converter for augmenting the power from the propulsion vehicle source for use with a native vehicle charging//starting system, and a transport load transformer for converting power from the power sources to 3 phase power for powering the refrigeration system. A bank of batteries stores power from the sources for subsequent dispersal to the refrigeration unit.

Tractor trailer refrigeration unit

A system for transferring and igniting a fuel comprising a fuel supply and a cryogenic fuel processor connected to the fuel supply and operative to remove impurities from the fuel. The system includes a power supply and an injector-igniter. The injector-igniter includes an injector housing connected to the power supply and having a fuel inlet connected to the fuel processor. An actuator body is disposed in the housing and a conductor sleeve is connected to the power supply and supported between the actuator body and injector housing with a first annular gap between the injector housing and the conductor sleeve. There is also a second annular gap between the actuator body and conductor sleeve, wherein the first and second annular gaps are in fluid communication with the fuel inlet, whereby fuel provides a dielectric between the conductor sleeve and the injector housing.
