This application claims the benefit of priority to Korean Patent Application No. 10-2013-0139424, filed on Nov. 15, 2013, the entire contents of which is hereby incorporated by reference in its entirety into this application.
The present disclosure relates to a transmitter apparatus of a wireless power transmission system for charging a vehicle, and more particularly, to a technology of configuring a transmitter apparatus of a wireless power transmission system using a parking stopper used at the time of parking a vehicle.
An eco-friendly vehicle (electric vehicle, hybrid electric vehicle, and the like), which uses an electric motor as a driving source, is provided with a battery, in which the battery is charged by a plug-in charging method, a quick charging method, and the like which generally perform charging through a wire.
Recently, a technology of charging a high voltage battery of a vehicle using a wireless power transmission system has been developed. The wireless power transmission technology is developed to be free from a wire and may be classified into a magnetic induction type, a magnetic resonance type, and an electromagnetic wave type. A magnetic induction technology uses a non-radiation characteristic and a non-resonator and uses an electromagnetic induction principle which allows a receiver coil to induce electricity depending on a magnetic field generated from a power transmitter coil.
One of the most important factors which allows the wireless power transmission technology using the magnetic induction type to determine power transmission efficiency is a distance between the transmitter coil 2 and the receiver coil 3. However, as illustrated in
To solve the above problem, a technology of elevating the transmitter coil mounted on the ground or a technology of elevating the receiver coil mounted in the vehicle body has been used. However, all the technologies require a separate lift apparatus for elevating the coils, which causes increase of cost and complication of a configuration.
The matters described as the related art have been provided only for assisting in the understanding for the background of the present disclosure and should not be considered as corresponding to the related art known to those skilled in the art.
The present disclosure has been made in an effort to provide a transmitter apparatus for a wireless power transmission system for charging a vehicle configured using a parking stopper used at the time of parking the vehicle to be able to maximally reduce a distance between a transmitter coil and a receiver coil, thereby improving charging efficiency.
Further, the present disclosure has been made in an effort to provide a transmitter apparatus for a wireless power transmission system for charging a vehicle configured to improve charging efficiency without elevating a transmitter coil or a receiver coil, a separate lift apparatus is not necessary, thereby reducing cost and simplifying a configuration.
According to an exemplary embodiment of the present disclosure, a transmitter apparatus of a wireless power transmission system for charging a vehicle is provided. The apparatus includes a parking stopper configured to be fixedly mounted on a ground of a parking space. A transmitter is configured to be connected to the parking stopper and to include a transmitter coil which generates a magnetic field at the time of parking the vehicle.
The transmitter apparatus of a wireless power transmission system for charging a vehicle may further include a vehicle detection sensor configured to detect the vehicle entering the parking space.
The transmitter apparatus of a wireless power transmission system for charging a vehicle may further include a power supplier configured to supply a current to the transmitter coil. A controller is configured to receive a signal of the vehicle detection sensor to control an operation of the power supplier.
The transmitter may protrude backward of the parking stopper.
The transmitter may protrude forward of the parking stopper.
The transmitter may be disposed at the same height as the parking stopper and the transmitter coil may be mounted on the transmitter so that a distance between the transmitter coil and a receiver coil mounted in the vehicle is minimized.
The vehicle detection sensor may be integrally mounted on a front surface of the parking stopper which contacts a tire of the vehicle at the time of parking the vehicle.
The vehicle detection sensor may be fixedly mounted on the ground in front of the parking stopper.
The vehicle detection sensor may be a pressure sensor or a photo sensor.

The above and other objects, features and advantages of the present disclosure will be more clearly understood from the following detailed description taken in conjunction with the accompanying drawings.
Hereinafter, a transmitter apparatus of a wireless power transmission system for charging a vehicle according to exemplary embodiments of the present disclosure will be described with reference to the accompanying drawings.
As illustrated in
In this configuration, as illustrated, two parking stoppers 10 may be mounted to be spaced from each other in a horizontal direction, and if necessary, one or a plurality of parking stoppers may be mounted.
The transmitter 20 may protrude backward of the parking stopper 10 as illustrated in
The vehicle detection sensor 30 may be configured of a pressure sensor, a photo sensor, or the like. As illustrated in
As illustrated in
As described above, when the transmitter coil 21 is mounted in the parking stopper 10, the transmitter coil 21 is mounted on the parking stopper 10, so that the distance L2 between the transmitter coil 21 and the receiver coil 60 mounted in the vehicle may be minimized.
Hereinafter, an operation of the transmitter apparatus of a wireless power transmission system for charging a vehicle according to the exemplary embodiment of the present disclosure will be described.
When a vehicle 1 enters the parking space, the vehicle detection sensor 30 mounted on a floor of the parking space or the vehicle detection sensor 30 mounted in the parking stopper 10 detects the vehicle. In this case, a signal of the vehicle detection sensor 30 is transferred to the controller 50, and the controller 50 receives the signal of the vehicle detection sensor 30 to control the operation of the power supplier 40. Here, the transmitter coil 21 generates a magnetic field by the operation of the power supplier 40, the receiver coil 60 mounted at a lower portion of a vehicle body generates electricity depending on the generated magnetic field, and a battery 70 mounted in the vehicle is charged with the generated electricity.
Further, when the vehicle is charged and deviates from the parking space, the operation of the power supplier 40 ends by the control of the controller 50, such that the transmitter coil 21 does not generate the magnetic field any more.
According to the exemplary embodiment of the present disclosure as described above, the transmitter apparatus of a wireless power transmission system including the transmitter coil 21 uses the parking stopper 10 at the time of parking the vehicle to be able to maximally reduce the distance L2 between the transmitter coil 21 and the receiver coil 60 mounted in the vehicle body and improves the power transmission efficiency, thereby considerably improving charging efficiency.
Further, according to the exemplary embodiment of the present disclosure, the transmitter apparatus of a wireless power transmission system improves the charging efficiency of the vehicle battery 70 without elevating the transmitter coil 21 or the receiver coil 60, and thus, a separate lift apparatus is not necessary, thereby reducing cost and simplifying a configuration.
According to the exemplary embodiments of the present disclosure, the transmitter apparatus for a wireless power transmission system including the transmitter coil uses the parking stopper at the time of parking the vehicle to maximally reduce the distance between the transmitter coil and the receiver coil mounted in the vehicle body and to improve the power transmission efficiency, thereby considerably improving charging efficiency.
Although the present disclosure has been shown and described with respect to specific exemplary embodiments, it will be obvious to those skilled in the art that the present disclosure may be variously modified and altered without departing from the spirit and scope of the present disclosure as defined by the following claims.
