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 a future use of charge of the energy storage means in dependence on the routine; determining 35 a charging requirement for the energy storage means in dependence on the prediction; and 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. 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 and may provide a positive indication that no charging will be required in a particular period based on a determined charging requirement.
