The method involves determining a time period for an energy surplus or shortage of energy on a basis of forecast e.g. prediction. Energy transfer is accomplished into an energy storage (106) or from the energy storage depending on the time period. The energy transfer is accomplished by an energy flow plate (110) between the storage and an energy source and/or energy sink of a vehicle. The forecast of the time period takes place with respect to input variables such as present navigation data, past navigation data, drivers, driving profile, motoring information and route information. An independent claim is also included for a device for connection of an energy storage to an electrical system. Es wird ein Verfahren zur Ansteuerung eines elektrischen Energiespeichers in einem Fahrzeug angegeben, bei dem anhand einer Vorhersage mindestens eine Zeitdauer für einen Energieüberschuss oder einen Energiemangel ermittelt wird, bei dem anhand der mindestens einen Zeitdauer ein Energietransfer in den Energiespeicher oder aus dem Energiespeicher durchgeführt wird. Weiterhin werden eine entsprechende Vorrichtung sowie ein Fahrzeug mit einer solchen Vorrichtung vorgeschlagen.
