The invention relates to an energy-supplying double-deck carriage, in particular a passenger double-deck carriage, for power supply, in which a main transformer is arranged in the roof region, preferably on or at the roof, and moreover preferably substantially above a bogie.

An independent cart system includes an inductive link for contactless power transfer between a track and each mover as the mover travels along the track. A system for contactless data transmission between movers and a controller in the independent cart system includes a transmitter and/or receiver mounted on each mover and a complementary receiver and/or transmitter mounted on a track. The transmitter receives data to be transmitted across the inductive link and modulates a voltage present on either the primary or secondary winding to which it is coupled. The modulated voltage present on one winding induces a corresponding modulation on the voltage present on the other winding. A receiver operatively connected to the other side of the inductive link detects the modulated voltage and decodes the data from the modulated voltage received across the inductive link.

Systems and methods for charging an electric bus having a charging interface on its roof may include determining that an approaching bus is supposed to be charged at the charging station, lowering the charging head of the charging station to land on the roof of the bus, and moving the bus with the charge head on its roof to engage the charging head with the charging interface.

An apparatus comprises a first induction section comprising a first core and a first coil on the first core. A second induction section comprises a second core and a second coil on the second core. The first core comprises rail extensions, where at least two of the rail extensions extend from opposite ends of the first core. The second core comprises shoe portions located at respective ones of the rail extensions, where a gap is provided between each of the rail extensions and respective ones of the shoe portion. The second induction section is configured to move relative to the first induction section in a path along the extensions. The first induction section is configured to induce current in the second induction section, including when the second core moves relative to the first core along the extensions, to provide a contactless induction coupling between the first induction section and the second induction section.

A device for controlling a required pressing force from a current collector of a vehicle on an overhead line, a method for using such a device and a power car having at least one such device, utilize a pilot control circuit, a working pressure control circuit and an adjustment device including a relay valve. The pilot control circuit adjusts a pilot control pressure and the relay valve uses a pilot control pressure to control a power pressure to provide a required working pressure for the pressing force of the current collector.

According to one embodiment, an electricity storage device includes a first box, a second box, a storage battery, and a flow path. The second box includes a side plate and is housed in the first box. The storage battery is disposed in the second box while being connected to the side plate. The flow path is configured to include the side plate of the second box inside the first box and outside the second box and vertically penetrates the first box.

Disclosed are a charger and a method of charging an electric vehicle. A main body of the charger includes a plurality of sub main bodies coupled to each other to transform its shape. The charger with the main body having a first shape moves toward the electric vehicle, and is then transformed to have a second shape. The first shape refers to a shape allowing the main body to be movable on a ground, and the second shape refers to a shape making the main body occupy a smaller surrounding area of the electric vehicle than the first shape. The electric vehicle is charged as connected to the charger having the second shape. The charger does not obstruct traffic of other vehicles because its size is reduced during charging.

The present disclosure relates to an automatic transportation system that moves along a rail and is powered by induction feeding, and more particularly, to a terminal block configured to facilitate installation and extension of a cable for a configuration of an induction power track and to prevent a fire accident due to overheating in advance by an overheat detection unit provided therein and an automatic transportation system using the same.

The invention relates to a device for controlling and regulating a required pressing force from a current collector of a vehicle on an overhead line, a method for using such a device and a vehicle having at least one such device, wherein the device has a base control circuit, an additional control circuit and a working pressure control circuit. The base control circuit has a base control circuit adjustment device for adjusting a base pressure from a provided power pressure and the additional control circuit has a control device for adjusting an additional pressure from a provided power pressure, wherein the base pressure and the additional pressure act together to form a working pressure and to provide the required pressing force.

This disclosure provides systems and methods for charging a vehicle. A vehicle and charging station can be designed such that an electric or hybrid vehicle can operate in a fashion similar to a conventional vehicle by being opportunity charged throughout a known route.
