A rail vehicle is configured for extracting electrical energy from a power supply external to the vehicle and has at least one electrical energy storage unit. In a first operating mode, the rail vehicle travels by means of energy extracted from the power supply and without energy from the energy storage unit. In a second operating mode, the rail vehicle travels, at least in part, by means of energy from the energy storage unit and/or at reduced traction power in comparison to the first operating mode. The rail vehicle includes a controller set up for activating the first or the second operating mode, as a function of an upper consumption limit, which defines the permissible upper limit of the power that can be extracted from the power supply. The upper consumption limit is established in a variable manner so as to prevent power peaks in the power supply.

A charging system for an electric vehicle has an elongate enclosure having a plurality of sides and an at least partially open side. The enclosure defines a hollow interior. The charging system further includes a conductor rail disposed in the hollow interior and that is accessible through the at least partially open side of the enclosure. The conductor rail may be placed in electric communication with an electrical power source and thereby may be selectively placed in electrical communication with an electrical connector of an electric vehicle. The charging system may conduct electric current from the electrical power source to an electric power supply of the electric vehicle.

A method of locating an electric vehicle at a charging station having multiple chargers is includes, receiving at multiple fixed transceivers positioned at different locations in the charging station, signals from the electric vehicle as the electric vehicle moves in the charging station, and determining, at a controller, a current location of the electric vehicle in the charging station using the signals received by the multiple fixed transceivers.

The system includes a plurality of base stations; a power transmission line located beneath a surface of a road having a plurality of segments, each segment having at least one pair of coils and at least one capacitor electrically connected via a switch to the coils in the segment; and at least one vehicle having at least one power receiving segment having at least two coils, connected to at least one capacitor, wherein the at least one vehicle further includes a communication transmitter configured to transmit a power requesting signal, wherein the coils of the power transmitting segment are configured to receive the power requesting signal; and wherein each of the base stations is further configured to feed a plurality of the power transmitting segments with current at a resonance frequency, responsive to the power requesting signal.

Discussed are a charging management device, a wireless charging system, a server, and a method for providing wireless charging services. The server is one for managing wireless charging of a vehicle on a road and includes at least one processor, at least one memory that stores computer program instructions that, when executed, cause the at least one processor to perform operations, and a communication device configured to communicate with the vehicle and a charge control device. The operations include receiving, from the vehicle, a traveling route and location information of the vehicle, identifying at least one wireless charging station through which the vehicle passes on the traveling route based on the traveling route and the location information, and providing information on at least one identified wireless charging station to the vehicle.

A method and system include determining a resonant frequency of a vehicle system operably coupled with an external power source that provides voltage and current to the vehicle system. A first filter extracts a phase or a frequency component from the voltage provided by the external power source to generate a stabilizing voltage component. A second filter extracts a phase or a frequency component from the current provided by the external power source to generate a stabilizing current component. The stabilizing voltage component is out of phase with the stabilizing current component. A control input of a converter device of the vehicle system is determined based on the stabilizing voltage component, the stabilizing current component, and the resonant frequency. The stabilizing voltage component, the stabilizing current component, and the control input are communicated with the converter device to change the resonant frequency of the vehicle system.

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.

This misalignment detection device is provided with: a plurality of coils which receive lines of magnetic force generated by a power transmitting coil and are disposed side by side line-symmetrically with respect to an axis line as a symmetrical axis; a plurality of temperature sensors which are disposed adjacent to each of the plurality of coils and output temperatures; and a processing device for detecting misalignment of a power receiving coil with respect to the power transmitting coil along the axis line on the basis of a difference for evaluating a difference between the temperatures.
