Power supply control device for supplying electrical power to rail vehicle, has control unit controlling supply of energy from different sources of energy in response to characteristics of sources and by request for operation of vehicle

The device has multiple power supplies (6-8) located on a vehicle (1) and formed for provision of electrical power to a power supply of the vehicle. A power control unit (2) controls the supply of energy from different sources of energy in response to state and/or performance characteristics of the energy sources and by a request for operation of the vehicle. Electrical power output characteristics and/or electrical power consumption characteristics are formed by the state and/or performance characteristics of the power sources made of a wear model. Independent claims are also included for the following: (1) a vehicle (2) a method for equipping an electrical drivable vehicle with multiple power supplies. Die Erfindung betrifft eine Energieversorgungseinrichtung zur elektrischen Energieversorgung eines elektrisch antreibbaren Fahrzeuges mit einer Mehrzahl von auf dem Fahrzeug angeordneten Energiequellen, die zur Bereitstellung von elektrischer Energie zur Energieversorgung des Fahrzeuges ausgebildet sind. Die Energieversorgungseinrichtung umfasst weiterhin eine Energie-Steuereinheit, die zur Steuerung der Energiebereitstellung aus den verschiedenen Energiequellen in Abhängigkeit von Zustands- und/oder Leistungscharakteristiken der Energiequellen und von einer Betriebsanforderung des Fahrzeuges eingerichtet ist.
