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.
