The auxiliary AC system includes a temperature measurement device configured to generate a variable output based on an air temperature in an environment proximate to the AC system and a compressor control circuit communicably coupled to a variable speed motor. The compressor control circuit is configured to receive the variable output from the temperature measurement device, determine that the output indicates a change in the air temperature, and generate a control signal for the variable speed motor, the control signal including a current having a magnitude depending on the extent of the change to vary a rate at which a compressor pressurizes a refrigerant vapor.

Compressor control circuit

A mounting structure for a compressor assembly of an auxiliary air conditioning system for a vehicle includes a mounting plate that includes a first surface, a second surface, a first plurality of apertures, and a second plurality of apertures. The mounting structure also includes a plurality of mounts disposed at the first surface, the plurality of mounts including a mount attached to the mounting plate via fasteners extending through the first plurality of apertures. The mounting structure also includes a mounting panel of a compressor unit of the auxiliary air conditioning system. The mounting panel includes a main portion having mounting apertures overlapping the plurality of mounts. Fasteners are disposed at the mounting apertures to attach the mounting panel to the mounting plate via the plurality of mounts.

Universal mounting plate for an auxiliary air conditioning system

A vehicle includes an engine, an alternator, and a battery bank electrically connected to the alternator via a connection line. The connection line includes a current sensor configured to measure an electrical current through the connection line. The vehicle also includes a start-stop system configured to determine, during a time when the engine is off, that a voltage of the battery bank is below a first threshold value for a first predetermined period, provide a control signal to a starter to start the engine to initiate charging of battery bank, determine, by the current sensor, that the electrical current is below a second threshold value, and in response to the determination, provide a control signal to turn the engine off to terminate the charging of the battery bank.

Systems and methods for auxiliary battery charging

A vehicle includes an engine, a start-stop system configured to stop and restart operation of the engine in response to predetermined triggers, and an auxiliary air conditioning AC system including a controller communicably coupled to the start-stop system. The start-stop system is configured to provide a first indication to the auxiliary AC system indicating ignition of the engine and a second indication to the auxiliary AC system after stopping the engine. The auxiliary AC system is configured to turn off the auxiliary AC system in response to receiving the first indication and restart the auxiliary AC system in response to receiving the second indication.

Systems and methods for automatic air conditioning restart

An assembly may include an auxiliary power unit housing, a battery box, and a pair of brackets. The battery box may include a base, a first cover and a second cover. The first cover may be removably attached to the base. The auxiliary power unit housing may be mounted to the second cover. The first cover may include a lip that engages a flange of the second cover. The brackets may extend laterally outward from lateral sides of the base.

Battery and auxiliary power unit mounting system

A bulkhead for a transport refrigeration unit (TRU) is provided. The bulkhead is configured to create optimal air flow on both a front side (e.g. the side where the condenser unit is located) and a rear side (e.g. the side where the evaporator unit is located) of the bulkhead, provide structural support for various components of the TRU, and provide a thermal barrier between the front side and the rear side. Also, the bulkhead is configured to include an access door and a service opening that allows a user to access TRU components located on the rear side of the bulkhead via the front side of the bulkhead. Further, the rear side of the bulkhead is configured to provide a removal support shelf that can be used as a resting surface or a sliding surface for removing components located on the rear side of the bulkhead out of the TRU from the front side of the TRU via the service opening by removing the access door.
