A method 30 for determining a charging requirement for an energy storage means of a vehicle comprising: determining 31 a routine of use of charge of the energy storage means; predicting 33 what the state of charge of the energy storage means will be at the completion of an event in dependence on the routine; determining 35 a charging requirement for the energy storage means in dependence on the prediction; providing 37 an output to a user of the vehicle indicative of a time at which an increase in the state of charge of the energy storage means will be required in dependence on the determined charging requirement; and indicating to the user either that an increase in a state of charge will be required or will not be required upon completion of the event. The energy storage means may be a battery for an electric vehicle EV or hybrid electric vehicle HEV. A system is provided to carry out the method. The system may reduce user range anxiety.
