The present disclosure relates to a power supply device for hybrid construction machinery, and more particularly, to a power supply device for hybrid construction machinery, which is capable of reducing engine loads and facilitating improvement of engine efficiency by excluding a starting motor used in general hybrid construction machinery and an alternator for charging a battery from hybrid construction machinery, such as a hybrid excavator or vehicle, which commonly uses an engine and an electric motor as a power source and includes an electric energy storage device, and a method for the same.

The present invention relates to an electrically driven single-axle tractor for coupling with, and powering of, various pieces of equipment, comprising: a frame; a drive axle, connected to the tractor frame, provided with one pair of wheels; a primary electric motor coupled to the drive axle; at least a secondary electric motor coupled to an equipment drive shaft for releasable coupling with a piece of equipment; and, at least one electrical energy source, as power supply of the primary and secondary electric motor. The invention also provides an assembly of such a tractor and a piece of equipment as well as a method for driving such a tractor.

A control system for a plug-in hybrid vehicle has a drive system having a starter motor, a transverse engine, and a motor/generator, and also has a power supply system having a high voltage battery; a capacitor; and a hybrid control module that controls charge and discharge of the capacitor. In the control system for an FF plug-in hybrid vehicle in which external charging of the high voltage battery is available, the hybrid control module starts the starter, performs a mode selection control and a charge/discharge control, maintains the capacitor voltage equal to or higher than a voltage that allows the starter to start-up when a CD mode is selected at the time of ignition ON, and maintains a capacitor voltage equal to or less than a voltage at which deterioration does not proceed at the time of ignition ON with the CS being selected.

A work vehicle includes a vehicle body frame, an outer cover, an engine compartment, a cooling compartment, a partition wall, an inverter, and a capacitor. The engine compartment contains an engine. The cooling compartment contains a cooling device. The partition wall separates the cooling compartment from the engine compartment. The inverter and the capacitor are disposed between the partition wall and the cooling device. The inverter is positioned above the capacitor. A length of the capacitor in the vehicle width direction is greater than a length of the inverter in the vehicle width direction. At least one of a first side surface of the outer cover positioned leftwards of the left side surface of the inverter and a second side surface of the outer cover positioned rightwards of a right side surface of the inverter is separated from the inverter by a gap.

An energy efficient vehicle and a disc-type dynamic motor thereof are disclosed. The vehicle comprises front wheels and rear wheels, and a gasoline engine is assembled in the vehicle for driving a generator producing power. The power is transported to a capacitor battery via a circuit control system and then to disc-type dynamic motors, which are assembled with the rear wheels, from the capacitor battery via two power lines respectively, whereby the disc-type dynamic motors directly driving the vehicle travelling at high-speed and high torque via the wheels. Accordingly, the energy efficient vehicle does not include transmission devices, such as the clutch, the transmission, the power transmission shaft, and the differential. The power produced by the generator is directly provided to the disc-type dynamic motors to drive the vehicle travelling and is enough to drive the disc-type dynamic motors, so the vehicle does not need to stop for charging.

To provide a vehicle drive device capable of efficiently driving a vehicle by using in-wheel motors without falling into the vicious cycle between enhancement of driving via the motors and an increase in vehicle weight. The present invention is a vehicle drive device that uses in-wheel motors to drive a vehicle and includes in-wheel motors (20) that are provided in wheels (2b) of a vehicle (1) and drive wheels, in which the in-wheel motors generate the maximum output power in a high revolutions range equal to or more than a predetermined number of revolutions that is more than zero.

The disclosure is directed to an apparatus for generating energy in response to a vehicle wheel rotation. The apparatus may include a first roller comprising a curved roller surface configured to be positioned in substantial physical contact with a first wheel of the vehicle. The first roller may be configured to rotate in response to a rotation of the first wheel. The apparatus may further include a first shaft rotatably couplable to the first roller such that rotation of the first roller causes the first shaft to rotate. The apparatus may further include a first generator operably coupled to the first shaft. The generator may be configured to generate an electrical output based on the rotation of the first shaft and convey the electrical output to an energy storage device or to a motor of the vehicle that converts electrical energy to mechanical energy to rotate one or more wheels of the vehicle.

The disclosure is directed to methods and systems for provisioning mobile electric vehicles with various operational settings data transmitted over the air. A vehicle or its components may operate according to operational settings corresponding to operational settings data included in the vehicle components. A server that is remote to the vehicle may comprise operational settings data and may transmit operational settings data to the vehicle. The server may transmit operational settings data automatically, such as on a periodic basis, in response to a request, such as from a user or from a vehicle component or anytime new or updated operational settings data are available for the vehicle or its components.

An articulated vehicle having at least two vehicle parts which are connected to and articulated relative to each other is provided. The vehicle includes a front vehicle part and at least one rear vehicle part arranged behind the front vehicle part with respect to a longitudinal direction of the vehicle. The front vehicle part has a first drive unit including at least an electric motor and a first energy storage system; and at least one rear vehicle part has a drive unit including at least an electric motor and an energy storage system. Each rear vehicle part includes an individual electrical system that is galvanically isolated from the front vehicle part and from each other at least under normal driving conditions.

An improved Center High Mounted Stop Lamp (CHMSL) harvests electrical power while providing additional features when the CHMSL is not powered during a brake application. Electronic circuitry determines if the different sources of electrical power have sufficient energy to activate the light-emitting device; senses a vehicle braking or emergency event to activate the light-emitting device upon sensing the event; and switches from one source of electrical power to a different source of electrical power if it is determined that a particular source of electrical power has become depleted or incapable of activating the light-emitting device. The different sources of electrical power may include a supercapacitor, a rechargeable battery, or a primary battery. The electronic circuitry operative to sense a braking or emergency event may include a brake signal input or an inertial measurement unit (IMU).
