Abstract

An energy storage system for a track-guided vehicle includes at least one electrical energy storage device and at least one electrochemical energy storage device connected through at least one converter to a supply line and to a drive unit for the vehicle. Individual phases of said at least one converter can be operated as independent direct-current controllers for independent charging and discharging of different energy storage devices.
