A system of a vehicle may include an electrical load, a generator, and first and second conduits. The electrical load of the vehicle may include a high energy device that utilizes above 270 volts during operations of the vehicle. The generator may be coupled to an engine of the vehicle and configured to generate electrical power at a voltage above 270 volts for the electrical load of the high energy device during operations of the vehicle. The first and second conduits may be arranged along each other to house respective first and second conductors that are electrically disposed between the electrical load and the generator.

Electric generators are described herein. The electric generators include an interior machine formed of an interior rotor and an interior portion of a stator, and an exterior machine substantially concentric to the interior machine. The exterior machine includes: an exterior rotor substantially concentric to the interior rotor, and an exterior portion of the stator. Each of the interior machine and the external machine are driven by an engine to produce a respective current. The described electric generators can be used in diesel electric locomotives.

An apparatus for controlling supply of power of a battery is provided. In particular the apparatus supplies battery power to various loads within a vehicle by a release of a door-lock using a key. The battery power is supplied to the loads by rotation of the key for releasing the door-lock when the power of the battery supplied to the various loads is blocked to prevent over-discharge.

A power generator unit includes a crankshaft-connecting unit and a power supply unit adapted to be arranged substantially in a left-right direction in which a crankshaft of a vehicle extends. The crankshaft-connecting unit includes a recharge generator adapted to be disposed on and actuated by the crankshaft, and a transmission shaft adapted to extend in parallel with and be driven rotatably by the crankshaft. The power supply unit includes a main shaft connected coaxially to the transmission shaft, and a supply generator connected to the main shaft and actuated by the main shaft. A portion of the transmission shaft is covered by the power supply unit.

A power supply system may include a first voltage converter provided between a first power storage device and a power feed line. The first voltage converter may include a first reactor, a first upper switching element, a first lower switching element and a first shutoff device. The first shutoff device may be provided in a first path between the other end of the first reactor and a connection point. The connection point may be a connection point between the power feed line and the second supply line. The first shutoff device may be configured to shut off the first path when short circuit failure occurs in the first upper switching element.

There is provided a method of moving an aircraft using an aircraft mover, in various instances, an aircraft tractor. The method comprises: a] accelerating the aircraft up to speed using one or more electric motors drivable by at least a fast-discharge electrical-energy storage and supply device during a high-power requirement of the aircraft mover; b] substantially maintaining a speed of the aircraft using a slow-discharge electrical-energy storage and supply device during a low-power requirement of the aircraft mover; c] monitoring a charge status of the slow-discharge and fast-discharge energy storage and supply devices and when a predetermined charge status is reached, automatically charging the slow-discharge and/or fast-discharge energy storage and supply devices via an onboard electricity generator; and d] regeneratively recharging the slow-discharge and/or fast-discharge electricity-energy storage and supply devices during at least deceleration of the aircraft coupled to the aircraft mover. There is also provided a method of controlling the power distribution to the motors within the aircraft mover, a dual electrical-energy storage and supply system and controller for implementing the method, a hybrid power delivery system for an aircraft mover incorporating the dual electrical-energy storage and supply system and controller, and an aircraft mover using the systems.

A battery including an output terminal, an electric storage device, a monitoring apparatus including a detector and a controller, the detector being configured to detect a variation value corresponding to an amount of charge of the electric storage device, a relay connected to the output terminal and the electric storage device, and a communication unit connected to the controller. The controller is configured to execute an opening process to switch a state of the relay from a closed state to an open state and to cause the communication unit to receive an input signal from outside.
