An electrical portal wheel hub system is coupled with a wheel and has an electric motor/generator, such as an axial flux motor configured therein and configured to provide power or torque to drive the wheel. The electric motor may be offset vertically from the rotational axis of the wheel to provide additional ground clearance. The electric motor may drive an input gear that is coupled with an output gear that in turns drives the wheel mount and wheel. The gearing ratio can be selected based on the application. A drive axle may from the vehicle may couple with the electric motor and the electric motor may be used to provide supplemental power to drive the wheels. The hub casing may provide mounts for the upper and lower A-arms as well as for a steering arm. The electric motor may act as a generator to charge a battery.

An onboard DC charger for an electric vehicle, wherein the electric vehicle includes an electric machine and a power conversion device that is a drive circuit for the electric machine and a charging circuit for the on-board battery. The one or more electric machines of the vehicle are mounted to the body for providing locomotive energy, wherein the or each machine has a stator, a rotor mounted to the stator for rotation, and one or more windings; and a controller for operating in a first state and a second state wherein, in the first state, the controller allows current to be drawn from the DC energy source for energising at least one of the one or more windings such that the electric machine provides the locomotive energy and, in the second state, the controller controls the position of the rotor relative to the stator and allows at least one of the one or more windings to be energised to provide a charging current to the DC energy source.
