A tracked vehicle comprising an electric machine assembly, a first and a second track coupled to the electric machine assembly, and an electric connection device, connectable to a power supply apparatus outside the tracked vehicle and connected to the electric machine assembly to exchange electrical energy with the power supply apparatus during the operation of the tracked vehicle.

An overhead line system provides electrical energy for an electrically driven vehicle by use of an overhead line. The overhead line system has a plurality of catenary systems which each have a contact wire connected to a carrying cable by a plurality of connecting devices and which are arranged, on the basis of parallel zones, to form a continuously accessible overhead line. The overhead line system further has an overhead line which is arranged in a curvature section in such a way that the vertical projection of the overhead line has a curved profile in a horizontal plane. The overhead line system also has a curved parallel zone which is arranged in the curvature section in such a way that the vertical projection of the parallel zone into the horizontal plane follows the curved profile of the projection of the at least one overhead line in the curvature section.

An energy management system is provided for a hybrid electric or electric vehicle including an electrical power collector for intermittently collecting electrical power from an external power supply track during driving of the vehicle. The energy management system is arranged to distribute electrical power from the electrical power collector to at least one electrical auxiliary load of the vehicle when collecting electrical power from the external power supply track. The enemy management system includes a control unit configured to control operating characteristics of the at least one auxiliary load depending on if the vehicle operates in a power collecting mode or in a non-power collecting mode.

A vehicle may include a chassis, a motor, a pantograph, and a pantograph support structure. The pantograph may engage overhead wires and transmit electrical current to the motor. The pantograph support structure may include first and second leg frames, a lateral frame, and first and second bearing mount assemblies. The leg frames may include lower ends attached to the chassis. The lateral frame may be supported by the leg frames and disposed at upper ends of the leg frames. The lateral frame may support the pantograph. The first bearing mount assembly may be attached to the lower end of the first leg frame and may connect the first leg frame to the chassis. The second bearing mount assembly may be attached to the lower end of the second leg frame and may connect the second leg frame to the chassis.

A vehicle is provided that connects to an power structure for powering and guiding the vehicle. The power structure includes a trolley, a track along which the trolley runs, a power source connected to the track, and a cable connected to the trolley and configured to attach to the vehicle moving on a surface. The vehicle includes a chassis and a cable connected to the chassis and configured to mechanically and electrically connect the vehicle to the power structure. The chassis includes a connector rotatable 360 degrees, and the cable connects to the chassis through the connector.

An electric vehicle control device includes a power conversion device, an auxiliary power source device, a charging device, an electricity storage device, and a controller. The power conversion device receives power supplied from an overhead line in an electrified section to perform power conversion, and supplies driving power to a vehicle driving motor. The controller connects the electricity storage device with the charging device and causes the charging device to charge the electricity storage device in the electrified section, and causes the electricity storage device to supply stored power of the electricity storage device to at least the power conversion device, instead of the power from the overhead line in a non-electrified section.
