An electrical system for providing electrical power to an electric machine, where the electrical system includes a single point disconnect switch for multiple battery systems. The single point disconnect switch may be remotely mounted. In some examples, operation of the disconnect switch disconnects a first battery system, e.g., a 12 VDC nominal battery system, which, in turn, causes a disconnection of a second battery system, e.g., a 48 VDC nominal battery system.

Single disconnect switch for multiple battery systems

One embodiment of a hydraulic system for a machine has a first hydraulic circuit including a first pump coupled to a first hydraulic actuator configured to move a first implement of the machine. A second hydraulic circuit includes a second pump coupled to a second hydraulic actuator configured to move a second implement. An electric motor mechanically couples to the first pump and to the second pump. An operator interface receives input from an operator requesting movement of the first and second implements. A controller communicatively coupled to the electric motor and to the operator interface determines, based on the requested movement of the first and second implements respectively, first and second flow allocations respectively for the first and second pumps and determines respective target displacements for the first and second pumps. The controller also determines first and second target electric motor speeds based on the target displacements for the first and second pumps, respectively, and controls the electric motor to operate at the larger of the first and second target electric motor speeds.

Method and systems for controlling electrically-powered hydraulic circuits

A system for controlling a heating and cooling system for use on a machine includes a condenser, an evaporator assembly, an electric motor driven compressor, and a master controller operable to determine and regulate an operational speed of the compressor. The master controller includes a plurality of control algorithms each receiving respective dynamic input information and outputting a respective controller speed request based upon the respective dynamic input information.

Method and system for controlling a compressor for an HVAC module

A mounting system is provided for supporting a weight of a compressor in a mobile application. The compressor may include a top end and a bottom end. The mounting system may include a housing having a top plate and a bottom plate, the top plate being disposed a distance above the bottom plate. A mounting bracket may be connected to the top plate and the bottom plate. An isolation assembly may be disposed on the mounting bracket and may be configured to connect to the compressor at a connecting location below the top end and above a location at or adjacent to the bottom end of the compressor. The isolation assembly is configured to support the weight of the compressor at the connecting location without the compressor being supported adjacent to its bottom end.

Compressor mounting system

A temperature sensing assembly for monitoring a temperature of a pipe in a system. The temperature sensing assembly includes an insulator body having a first end, a second end, an outer surface, and an inner surface. The outer and inner surfaces extend between the first and second ends. The inner surface is configured to receive a portion of the pipe. A temperature sensor is disposed adjacent the inner surface and is configured to directly contact the pipe when the pipe is received by the inner surface.

Air-conditioning assembly

An air-treatment system includes a cooling circuit, a first heat exchanger in thermal communication with the cooling circuit, and a secondary circuit in thermal communication with the first heat exchanger. The air-treatment system also includes a controller in communication with at least one of the cooling circuit, the first heat exchanger, and the secondary circuit. The controller is operable to receive at least one input indicative of a desired ambient condition, operable to receive at least one input indicative of current ambient conditions, operable to receive at least one input indicative of at least one of the cooling circuit operation and secondary circuit operation, and operable to change the operation of at least one of the cooling circuit and the secondary circuit when the current ambient condition is outside of a desired operation condition range.

Air-treatment system with secondary circuit

A dual airflow control system for an environment having a first air zone and a second air zone. The system includes a first input device operable to generate a first input signal indicative of a desired airflow to the first zone and a second input device operable to generate a second input signal indicative of a desired airflow to the second zone. First and second flow regulators are configured to regulate airflow to the first and second zones, respectively, such that the first and second regulators selectively provide the airflow to each of the first and second zones based on the first and second input signals. A single actuator is associated with the first and second flow regulators. The actuator is operable to simultaneously actuate the first and second flow regulators based on an input from the first and second input devices to allow the desired airflows to the first and the second zones.

Airflow control system

A thermal management system for a vehicle includes an engine operable to generate energy. An energy storage unit may be associated with the engine and adapted to receive and store the energy generated by the engine. A temperature control unit may be associated with the energy storage unit and adapted to control a temperature in the vehicle. The temperature control unit may be adapted to selectively draw stored energy from the energy storage unit to control the temperature when the engine is not operating. A controller may be adapted to monitor an operating condition of the thermal management system and to control the transfer of the energy from the engine to the energy storage unit based on the monitored operating condition.
