A power supply system includes a first controller that, controls an MG1 inverter, a second controller that controls an MG2 inverter, and a voltage sensor that detects a voltage generated from a pair of output terminals. The first controller controls the MG1 inverter according to a target value of the voltage generated from the output terminals, irrespective of the magnitude of a deviation between the target value of the voltage generated from the output terminals, and the detected voltage. The second controller controls the MG2 inverter according to the deviation. This processing is implemented by an effective value computing unit, effective value PI control unit, and a neutral point output voltage command unit.

A system includes a remote control device that is useable by an operator interacting with a materials handling vehicle. The remote control device includes a wireless communication system including a wireless transmitter and a rechargeable power source. The system further comprises: a receiver at the vehicle for receiving transmissions from the wireless transmitter; a controller at the vehicle that is communicably coupled to the receiver, the controller being responsive to receipt of transmissions from the remote control device; and a charging station at the vehicle, the charging station for charging the rechargeable power source of the remote control device.

Systems to wirelessly power transfer to a tailgate are disclosed. An example disclosed vehicle includes a transmitting circuit in a body of the vehicle configured to transmit power via wireless capacitive transfer. The example vehicle also includes a receiving circuit in a tailgate of the vehicle configured to receive power via wireless capacitive transfer.

A power supply system including: a battery; a plug receiver into which a plug of a device can be plugged in a passenger compartment of a vehicle in which an occupant of the vehicle can ride; a floor that partitions between the passenger compartment and a space under the floor of the passenger compartment, the battery being mounted in the space under the floor; and an electric wire that extends from the battery, through the floor, and to the plug receiver and that can supply electricity.

A vehicle includes an engine, an electric motor, an electrical storage device and a controller. The electric motor generates electric power by using driving force of the engine. The controller controls supply of electric power, which is at least one of electric power generated by the electric motor or electric power stored in the electrical storage device, to an outside of the vehicle. The controller selects, on the basis of setting made by a user, whether to permit or prohibit generation of electric power by using the driving force of the engine.

A refrigeration cycle device includes an air heat exchanger that heats air to be blown into an interior of a vehicle compartment using refrigerant discharged from a compressor, a high-stage side expansion valve decompressing the refrigerant flowing out of the air heat exchanger, and a battery heat exchanger that heats air to be blown to a battery using the refrigerant decompressed by the high-stage side expansion valve. In an air heating-warming up mode of heating the air for the interior and the air for the battery, a refrigerant discharge capacity of the compressor is controlled such that an air temperature for the interior approaches a target air temperature, and an opening degree of the high-stage side expansion valve is controlled such that a battery temperature becomes within a predetermined reference temperature range. A selector switch allows a passenger to select which operation of air conditioning or warming-up is prioritized.

A system for providing redundant electric power to at least one vehicle component is disclosed. The system includes at least one power management unit connectable to a vehicle power network; and one or more storage units coupled to the at least one power management unit for receiving electric power to be stored in the one or more storage units. The at least one vehicle component is connectable to at least two of the storage units to enable a redundant electric power supply.

A remote control device that is paired with a first vehicle, such that the remote control device wirelessly communicates with the first vehicle, is paired with a second vehicle via a pairing process. The pairing process is initiated by physically contacting a component of the remote control device with an element of the second vehicle. The pairing process also unpairs the remote control device from the first vehicle, such that the remote control device no longer wirelessly communicates with the first vehicle, and the remote control device wirelessly communicates with the second vehicle.

Disclosed embodiments include apparatuses, systems, and methods for transferring electrical power between an electrical power system of a vehicle and another device. In an illustrative embodiment, an apparatus includes a wireless transfer unit electrically coupled with a high voltage system of a vehicle and configured to enable wireless bidirectional power exchange between the high voltage system and an auxiliary device. The high voltage system is operable to power a drivetrain of the vehicle and the auxiliary device is separate from the vehicle and configured to at least one of provide electric power to and receive power from the high voltage system. A transfer control unit is configured to communicate with the wireless transfer unit and control at least one parameter specifying a transfer of electrical power between the high voltage system and the auxiliary device.

This disclosure details exemplary portable power systems for vehicles. The portable power systems may be configured as a secondary battery pack that is removably stored within a front trunk of a vehicle. The portable power systems may include a plurality of individually removable battery units that can be used to extend vehicle driving range or power electrically powered devices that are separate from the vehicle. In some embodiments, when the portable power system is stored in the vehicle and an electrically powered device is connected to the portable power system, the vehicle may be controlled in a Following Mode in which the vehicle is autonomously moved to follow an operator of the electrically powered device.
