Abstract

An energy management system for a transport device, in particular for a motor vehicle running on fuel and electricity, includes an energy source, an intermediate energy store and an electric energy consumer, in particular an electric drive. Control and/or regulation of the provision of energy, which is dependent on information relating to future energy requirements and supplied by means of at least one part of the transport device can be carried out by the energy management system by means of the intermediate energy store and/or the energy requirements.
