Description

The invention relates to techniques for wireless energy transfer and can be used to power trolley buses, electric vehicles, electric forklifts, trams, electric tractors, electric locomotives and other electric vehicles, as well as for wireless power supply of electronic and electrical devices.
A known method of powering a rail electric vehicle, for example, a tram and an electric train, provides for the transmission of electric energy through a single-wire contact network through a current collector to vehicles, converting the electric energy of the network to specified values and supplying it to traction electric motors (AS USSR No. 1729843, MKI 6 B60L 9/08, 1992 BI No. 16). The disadvantage of this method of power supply of a rail vehicle is the large metal consumption of the device necessary for implementing the method, consisting of a two-wire conductive line containing a contact wire and a metal rail.
Another disadvantage is the impossibility of using this method for powering a non-rail electric vehicle, for example an electric car or a trolley bus.
A known method of powering an electric vehicle by supplying electric energy through a two-wire contact network, rod trolley current collectors to traction electric motors (AS USSR No. 1440767, MKI 6 V60L 5/34, BI No. 44, 1988).
The disadvantage of this method is the high consumption of conductive material. Another disadvantage is the low reliability of the trolley current collector, especially when moving at high speed and when changing the direction and sequence of movement.
A known method of non-contact transmission of electrical energy using electromagnetic induction. In this case, the wires of a single-phase traction line of two insulated cables connected shortly at the end of the line and connected to an alternating current substation transfer energy through an air gap to a receiver of several turns of wire forming the secondary winding of the transformer. The receiver is mounted on an electric vehicle and moved relative to the line. The alternating magnetic flux generated by the current in the line induces an electromotive force (EMF) in the receiver winding through the air gap, as in a conventional transformer. For induction contactless transmission, a high frequency current of 2-20 kHz is used. For rail transport, the upper air suspension of high-frequency traction cables is used, and for rail transport, underground laying of traction cables (V.E. Rosenfeld, N.A. Staroskolsky. High-frequency contactless electric transport. Moscow: "Transport", 1975, p. 4-8).
A disadvantage of the known method and device for the non-contact transmission of electrical energy to a vehicle is the large losses in the traction line due to the large inductive resistance of the wires at a high frequency. Due to the high frequency, significant emfs of self-induction arise in the turns of the receiver winding and in the cable line, the active component of which is directed counter to the voltage of the substation supplying the traction network. To compensate the inductive resistance and EMF of self-induction, capacitors are connected in series in the line and in the receiver. To reduce energy dissipation, a transposition is made - the traction cables are crossed, while in the transposition places there are difficulties with the vehicle's power supply, since the EMF is not induced in the receiver's current crossing the traction cables. Due to the high cost and low efficiency of the non-contact method of transferring electrical energy using electromagnetic induction, this method has not found practical use.
The closest in technical essence to the present invention is a method of powering electric vehicles and a device for its implementation by supplying electrical energy through a high-frequency converter and a single-conductor contact network to individual vehicle current collectors by electrostatic induction through an air gap between an isolated single-conductor line and a current collector from a resonant single-conductor system power supply at a frequency of 0.1-400 kHz and voltage uu line 0.5-1000 kW (RF patent №2297928, IPC B60L 9/00, BI №12, 2007).
In an embodiment of the power supply method for electric vehicles, power is supplied to the vehicle by electrostatic induction through an air gap between a single-conductor cable line installed in the road surface or in the ground directly near the surface and a current collector installed under the bottom of the electric vehicle.
In another embodiment of the power supply method for electric vehicles, power is supplied through the air gap between the single-conductor line and the current collector installed above the electric vehicle or at the side surface of the electric vehicle.
A device that implements the known method is a source of electrical energy, to which a frequency converter is connected, and a single-conductor line for each lane and current collectors of electric vehicles, the device is made in the form of a resonant electric system with a resonant frequency of 0.1-400 kHz and a voltage of a single-conductor line 0.5-1000 kV with an air gap of 0.1-50 m between the single-conductor line and the current collector, the device contains two, one transmitting and one receiving, resonant circuits, us swarming on the same frequency f 0 = 0.1-100 kHz, the transmission input circuit coupled to the frequency converter and output through the step-up transformer and a resonant single-conductor line through the current collector to the air gap; the current collector is made in the form of a thin insulated sheet of conductive material and is mounted on the vehicle parallel to the single-conductor line, the input of the second receiving resonant circuit is connected to the current collector through a resonant step-down transformer, and the output through the rectifier and control unit to the electric motor of the electric vehicle.
Using the known method and power device for electric vehicles provides an increase in efficiency, reliability, longer service life, reduced energy losses and multi-row movement of electric vehicles. The disadvantage of this method is the low transmitted power through the air gap, limiting the ability to move a cargo vehicle and its speed.
The objective of the invention is the creation of a wireless method of powering electric vehicles and a device for its implementation, providing high power and speed of movement of electric vehicles with multi-lane (multi-row) movement.
As a result of the use of the present invention, it becomes possible to wirelessly transmit electrical energy and power cargo electric vehicles when moving them over a long distance.
