An apparatus for controlling a range extender 104 in an electric vehicle 100 comprises means for receiving trip information, means for retrieving power usage information relating to a previous trip, the previous trip having trip information which is at least in part in common with the trip information; and means for activating the range extender 104 in dependence on said power usage information. The range extender 104, which may be a diesel internal combustion (IC) engine, or a hydrogen fuel cell, connected to an electric generator, may be controlled to activate based on stored power usage data related to previous journeys. Alternatively, the range extender 104 may be activated dependent on a state of charge of the battery 106. The range extender 104 may be controlled to operate at its most efficient operating point.
