VEHICLE OPERATION SYSTEM, CHARGE SYSTEM AND VEHICLE

摘要

To provide a vehicle operation system capable of practically operating a vehicle not requiring an overhead wire, a charge system used in the vehicle operation system and a vehicle. A voltage control device (82) in a vehicle (100) controls the polarity and magnitude of an output voltage depending on the electromotive force of a polyphase constant current motor (3) to supply a constant direction and constant magnitude of DC constant current to a polyphase constant current inverter (2), and also to perform discharge at the time of driving the polyphase constant current motor (3) and perform charge due to regenerative electric power at the time of braking until the polyphase constant current motor (3) stops. On the other hand, a charge system (200) is installed at a station, and a DC power supply device (101) is connected to an ultracapacitor (84) in the vehicle (100) through an electromotive rail (102) and a contact (88) in the vehicle (100) and also through an electrode (103), a steel rail 90 and a steel wheel (89) in the vehicle (100) to supply a DC electricity to the ultracapacitor (84) for charging.
