A method of scheduling heating of an after-treatment component of a vehicle comprises determining a predicted charge profile (72, fig 7) for an energy storage device (9, figure 1), such as a battery, of the vehicle and scheduling heating of the after-treatment component in dependence on the predicted charge profile. The vehicle may be a hybrid vehicle. The after-treatment component may be a catalyst or filter. A controller comprises an energy optimisation module 32 for generating a predicted charge profile for an energy storage device of the vehicle, and an exhaust after-treatment component management module 12 for scheduling heating of the after-treatment component based on the predicted charge profile. A vehicle comprises a system having the controller and an after-treatment component. Scheduling heating of the after-treatment component can also depend on a predicted engine torque profile (74, fig 7) or predicted heating requirements (76, fig 7) for the after-treatment component.
