The present disclosure relates to a vehicle 1 having an electric traction machine 2; a traction battery 6 for storing energy; and an inverter 12 for electrically connecting the electric traction machine 2 to the traction battery 6. The vehicle 1 includes an internal combustion engine 3 operable to charge the traction battery 6 depending on the speed of the vehicle. The internal combustion engine 3 having an electric starter motor 8 which is selectively energized by the traction battery 6. A controller 12 includes at least one processor 13 and a memory device 14. The at least one processor 13 is configured to control charging of the traction battery 6 by the electric traction machine 2 while an external driving force is applied to propel the vehicle 1. The at least one processor 13 is configured to control an electrical load on the electric traction machine 2 in dependence on a determined vehicle speed. The present disclosure also relates to a controller 12 for charging a traction battery 6; and to a method of charging a traction battery 6 also dependent on vehicle speed.
