In the casing (103b), a first cover (202) is formed on a surface of the casing (103b) opposing the power-receiving unit (153), and a second cover (203) opposing the first cover (202) is arranged between the first cover (202) and the power supply coil (103a).

A rail vehicle includes a car body having both a passenger space and a stowage space that is provided with a controller and at least one station for accommodating light electric vehicles. The stations have a chassis, a holding structure, a locking mechanism, and a power outlet. The holding structure can hold the light electric vehicle stationary. The locking mechanism can retain the light electric vehicle in the holding structure. The power outlet can deliver electrical power to a battery of the light electric vehicle when the light electric vehicle is secured in the holding structure and connected to the power outlet. The power outlet can be connected to an electrical power network of the rail vehicle. The controller can selectively send a release signal to the locking mechanism, so as to release the locking mechanism, and to selectively operate the power outlet so as to deliver the electrical power.

The present invention relates to a method for activating a segment for enabling electrical power delivery to vehicles, the segment being one of a plurality of segments consecutively arranged along a single track line of an electric road system that further comprises a base station, the method comprising: receiving, at the base station, identification data transmitted from a vehicle, the identification data identifying the vehicle; associating an activation key with the identification data with each other; transmitting the activation key from the base station to the segment; receiving, at the segment and via short range radio communication, an activation request sent from the vehicle, wherein the activation request comprises an identification key associated with the identification data; confirming, at the segment, that the received identification key is associated with the received activation key; and upon positive confirmation, activating the segment for enabling power delivery to the vehicle.

An electrified railway power supply system without negative sequence in the whole process and without power supply networks at intervals, can comprise an external power supply system, an input power supply system from external to internal, and an internal power supply system. For external power supply, single-phase power supply is changed to double-phase power supply, and power of a single phase is input to the power supply system within the train via a contactor on a left arm and a right arm of a double-phase pantograph. No neutral section for passing of phase separation is provided in the whole process of operation, and a plurality of sections in the whole process are provided with no power supply network at intervals, and the motor train unit can operate normally without mechanical support for the power supply network.

A method is provided for controlling a vehicle safety system in a vehicle provided with a current collector arranged to transmit electric power from a current conductor in the surface of a road. The current collector is controllable for vertical and transverse displacement relative to a longitudinal axis of the vehicle to contact and track the current conductor. The safety system includes at least one forward looking data collecting system for detecting obstacles on the road prior to impact with the current collector; and an electronic control unit for controlling at least power transmission and displacement of the current collector. The method involves performing the steps of detecting that an obstacle is located in the path of the current collector; transmitting data from the forward looking data collecting system to the electronic control unit; performing an object classification to determine a damage level for the dynamic charging system; determining an action to be taken by the safety system based on the determined damage level; and initiating the action in dependence of at least the determined damage level.
