A hybrid vehicle includes at least one axle, an energy storage device disposed within the hybrid vehicle, a fuel consuming engine, a power boosting feature, and a controller. The fuel consuming engine is operably connected to selectively provide power to at least one of the energy storage device and the at least one axle. The engine is capable of providing at least the mean but less than a peak power to drive the hybrid vehicle over a typical route. The power boosting feature is configured to provide the fuel consuming engine with additional power to achieve a desired power to accelerate the hybrid vehicle. The controller is adapted to selectively control power flow to the one or more axles from one or more of the energy storage device, the engine, and the power boosting feature to achieve the desired power.

An electric vehicle (1) includes a charging circuit (11), a battery (12) and a driving electric motor (13), and an air compressor (14), an air storage tank (15), a turbine (16) and a generator (17). Air is compressed and stored in the air storage tank when the air compressor starts up. The air storage tank is provided with a switch valve, and under the control of the switch valve the air stored in the air storage tank is fed to the turbine. By means of providing an air compressor, an air storage tank, a turbine and a generator, and using air energy to generate power and using the battery to supply power in parallel, the continuous mileage of the electric vehicle is increased. In addition, the service life of the battery is prolonged, because the battery is used in a low depth of charge/low depth of discharge manner.

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 apparatus is provided comprising a flywheel (112) for storing kinetic energy and an electrical machine (190) mechanically coupled to the flywheel and arranged for conversion between mechanical and electrical energy. The apparatus is arranged for transferring energy between the flywheel and a vehicle transmission via a variable ratio transmission (182). The electrical machine is coupled to the flywheel via a disconnect clutch which comprises a magnetic coupling (116).

A mobile mining machine includes a plurality of traction elements, a plurality of motors, a power source in electrical communication with the plurality of motors, and an energy storage system in electrical communication with the plurality of motors and the power source. Each of the motors is coupled to an associated one of the plurality of traction elements. Each of the motors is driven by the associated traction element in a first mode, and drives the associated traction element in a second mode. The energy storage system includes a shaft, a rotor secured to the shaft, a stator extending around the rotor, and a flywheel coupled to the shaft for rotation therewith. In the first mode, rotation of the motors causes rotation of the flywheel to store kinetic energy. In the second mode, rotation of the rotor and the flywheel discharges kinetic energy to drive the motors.
