Timed charging comprises two main features:
The preferred charging period feature allows the vehicle to use a cheaper rate of electricity, based on the household tariff. When set, the vehicle attempts to charge the vehicle within the time window selected. Preferred charging can be set via vehicle preconditioning. See PRECONDITIONING SETTINGS.
By setting a departure time, the timed charging feature makes sure that the vehicle is in an optimum state of charge before a journey. The timed charging feature attempts to charge the vehicle within the preferred charging time window. See TIMED CHARGING.
If it is not possible to fully charge the vehicle within the preferred charging period, charging may begin in advance. Charging outside of the preferred charging period makes sure that the vehicle is fully charged before the set departure time.
