Device for supplying electrical power to rail-bound vehicle, has energy storage devices storing electricity and delivering stored electricity into power supply network with respect to electrical power requirement of vehicle

摘要

The device has an energy recovery device (4) recovering a part of kinetic energy of a rail-bound vehicle (1) into electricity and supplying the recovered electricity into an electrical power supply network (3). Energy storage devices (5a, 5b) store electricity and deliver the stored electricity into the power supply network with respect to an electrical power requirement of the vehicle. A communication unit (6) transfers a feeding time (t2) and a power requirement time (t4) of the vehicle to the storage devices by Global system for Mobile Communication- Railway.
