A system and method monitor operation of a compressor, determine whether the operation of the compressor is outside of a designated range of values, and, responsive to determining that the operation of the compressor is outside of the designated range of values, one or more of (a) prevent communication of a signal to a system controller that controls operation of the compressor, (b) direct a gas from a reservoir to a pressure sensor used by the system controller to determine a gas pressure generated by the compressor, and/or (c) communicate the signal to the system controller that controls operation of the compressor.

A vehicle includes electric brakes, an engine with a starter, a battery and a controller. The battery has a voltage and is configured to power the starter, the electric brakes, and the controller. The controller is configured to, in response to a speed of the vehicle falling within a specified range without propulsive demand and while the voltage is greater than an upper voltage that varies based on a charge needed to engage the brakes to stop the vehicle, stop the engine.

An off-board battery charger for a vehicle may include a high-voltage connector having first, second and power supply connector ports. The first connector port connects to a vehicle controller via a first cable. The second connector port connects to a vehicle battery via a second cable. And, the power supply connector port is electrically connected with the second port and receives power via a power supply cable from a separate and external power supply.

A power system of an aircraft includes a hybrid energy storage system with at least two energy storage subsystems each having a different power-energy density. The power system also includes one or more electric motors operably coupled to the hybrid energy storage system and to an aircraft engine. The power system further includes a means for controlling one or more electric power flows of the hybrid energy storage system to/from the one or more electric motors based on a modeled electric power demand associated with an engine load of one or more spools of the aircraft engine.

Described is a telehandler (1) equipped with at an electric propulsion motor and with several containment compartments (100) for housing means (200, 300) for powering the motor. A compartment (100) is provided with an access opening to allow a user to insert or extract a source of electricity (200, 300) included in the power supply means. A plurality of electric batteries (200) is made available, each designed to be inserted in one of the compartments (100). An electricity generator apparatus (300) is provided for insertion in one of the compartments (100). The telehandler (1) is equipped with the following alternative power supply configurations: a fully electrical configuration wherein the power supply means comprise only one or more electric batteries (200); and a hybrid configuration wherein the power supply means include the electricity generator apparatus (300).

A safety switch input diagnosis device includes a circuit formed from a series connection of an emergency stop switch and a line having a resistor. A connection state of the emergency stop switch and failure modes of the lines are diagnosed on the basis of a voltage value at one end of the circuit. Consequently, an operation of the switch and failure modes of a circuit relating to the switch can be diagnosed.

The present disclosure relates to a power distribution architecture for an off-road vehicle. The power distribution architecture includes a work circuit and a propel circuit and is configured for facilitating bi-directional power exchange between the work circuit and the propel circuit.

A power delivery system includes a turbocharger assist device and an inverter. The turbocharger assist device is mechanically connected to a turbocharger that is operably coupled to an engine, and is configured to generate electric current based on rotation of a rotor of the turbocharger. The inverter is electrically connected to the turbocharger assist device via a bus, and is configured to receive the electric current generated by the turbocharger assist device via the bus and supply the electric current to power a load.

A modular charging and power system for generating and supplying electrical power to electric vehicles, hybrid electric vehicles, other manned and unmanned remotely operated vehicles, drones, robotics, marine and aerospace vehicles, equipment, or apparatus, portable power units, propulsion systems, and other electrically powered systems. The modular charging and power system comprises a racking system for retaining one or more interchangeable power modules. Each power module comprises a generator driven by a power unit, a compressor to deliver high-pressure driving fluid to the power unit, and a battery bank. Electrical power generated by the generator powers the compressor, the battery bank, and/or an external electronic device or system.
