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.
Claims15
An energy storage system for a track-guided vehicle having a drive unit and a supply line, the energy storage system comprising:
- a plurality of energy storage devices including at least one electrical energy storage device and at least one electrochemical energy storage device;
- and
- at least one converter electrically connecting said plurality of energy storage devices in parallel to the drive unit of the track-guided vehicle;
- said at least one converter electrically connecting said at least one electrical energy storage device and said at least one electrochemical energy storage device to the supply line;
- said supply line also connected to the drive unit of the track-guided vehicle;
- said at least one converter being a polyphase direct-current controller having individual phases to be operated as independent direct-current controllers for independent charging and discharging of different ones of said plurality of energy storage devices.
A combination, comprising:
- a track-guided vehicle having a drive unit and a supply line, and an energy storage system for said track-guided vehicle;
- said energy storage system including:
- a plurality of energy storage devices including at least one electrical energy storage device and at least one electrochemical energy storage device;
- and
- at least one converter electrically connecting said plurality of energy storage devices in parallel to said drive unit of said track-guided vehicle;
- said at least one converter electrically connecting said at least one electrical energy storage device and said at least one electrochemical energy storage device to said supply line;
- said supply line also connected to the drive unit of said track-guided vehicle;
- said at least one converter being a polyphase direct-current controller having individual phases to be operated as independent direct-current controllers for independent charging and discharging of different ones of said plurality of energy storage devices.
