The charging information may be transmitted to the charging server whenever the battery charging of the vehicle occurs, or may be transmitted at a predetermined periodic interval (eg, daily, weekly, monthly, etc.).

On the other hand, in the embodiment of the present invention has been described as mounting one transmitting end opposite to both side walls of the charging structure, but this is merely an exemplary presentation for the convenience and understanding of the description and the invention is necessarily limited thereto. As an example, as shown in FIG. 4, the transmitters 402a, 402b, 404a, 404b, 406a, and 406b are arranged in a transmitter array structure along both sidewalls of the charging structure at regular intervals. Of course you can.

Referring to FIG. 4, in the transmitter array structure, only two transmitters 402a and 402b are turned on when the vehicle enters the P1 point (starting point of the charging zone) without turning on / off all transmitters simultaneously. Turn off both transmitters 404a and 404b when entering, and turn on both transmitters 404a and 404b, and turn off both transmitters 404a and 404b when the vehicle enters P3 point. 406b), and the power control can be performed by turning off the two transmitters 406a, 406b when the vehicle leaves the P4 point (the end point of the charging zone), which can occur when the vehicle battery is wirelessly charged. Can effectively prevent power waste.

Here, vehicle entry and vehicle departure detection at each point may use detection sensors as in the foregoing description of FIG. 1. In addition, although only the transmitter array structure is illustrated in FIG. 4, similarly to FIGS. 1 and 3 described above, a display block, an alarm, a radio wave absorber, and a communication block may be provided to provide related services in the same manner. Of course.

2 is a block diagram of a vehicle device mounted on a vehicle for wireless charging according to the present invention, and may include an rectenna (rectenna + rectifier) 202, a charging block 204, a battery 206, and the like. .

Referring to FIG. 2, the rectenna 202 receives a microwave wireless power signal wirelessly transmitted through a horn antenna when the vehicle travels through a charging zone in a charging structure, and converts the microwave power signal into DC power through filtering and rectification. The converted DC power is transferred to the charging block 204.

Next, the charging block 204 means a conventional charging module which is well known in the art, and the battery 206 for an electric vehicle mounted in a vehicle using DC power transmitted from the rectenna 202. Charge it.

Next, a series of processes for charging a battery mounted in a vehicle while the vehicle is running by using the charging apparatus for an electric vehicle as described above will be described in detail with reference to FIGS. 5 to 7.

FIG. 5 is a flowchart illustrating a process of charging a battery mounted in a vehicle when the vehicle enters and drives a charging zone in the charging structure according to the present invention.

Referring to FIG. 5, while the charging device is executing the standby mode (step 502), the control block 108 checks whether a vehicle entrance detection signal is input from the entrance detection sensor 102 (step 504).

As a result of the check in step 504, when the vehicle entry detection signal is input, the control block 108 controls the voice guidance of the charging execution, i.e., via the alarm 114, for example, "charging starts." Voice guidance (hearing guidance) such as the control is generated (step 506). Therefore, the driver in the vehicle can recognize that the charging of the vehicle battery is started through the voice guidance.

In addition, when the vehicle entrance detection signal is input, that is, when the vehicle entry into the charging zone in the charging structure is detected, the control block 108 controls the execution of the charging mode, that is, generates a power transmission control signal to generate the power supply block 118. By outputting the microwave power in the power supply block 118, the microwave power for charging the vehicle battery is wirelessly transmitted at each transmitting end 122,126 (step 508).

Accordingly, the rectenna 202 in the vehicle device mounted on the vehicle receives the microwave-powered microwave wireless power signal and converts it into DC power, and the charging block 204 charges the battery 206 using the converted DC power. Let's go. In other words, the battery is naturally charged when the vehicle travels through the charging zone of the charging structure. Of course, for efficient charging of the battery it will be necessary to guide or guide the vehicle to run at a relatively slow speed in the charging zone within the charging structure.

Next, the control block 108 checks whether a departure detection signal from the departure detection sensor 104 is input, that is, a vehicle driving the charging zone 306 in the charging structure 304 is connected to the charging zone 306. It is checked whether to leave (step 510).

As a result of the check in step 510, if the vehicle departure detection signal is input, that is, when the vehicle leaves the charging zone in the charging structure, the control block 108 controls the transition to the standby mode, that is, the power transmission cutoff signal. Is generated and delivered to the power supply block 118, whereby the power supply block 118 turns off the output of the microwave power, so that the microwave power transmission at each of the transmitting stages 122, 126 is stopped (step 512).

That is, according to the present invention, when the vehicle travels the charging zone in the charging structure, the microwave power is wirelessly transmitted so that the battery mounted on the vehicle is charged, and when the vehicle leaves the charging zone, the transmission of the microwave power for charging the battery is stopped. In this way, the vehicle battery can be charged while driving the vehicle.

Of course, the microwave power wirelessly transmitted for charging the vehicle battery when the vehicle travels through the charging zone can be recovered through the wave absorber (multiple wave absorber structures) and reused as the microwave power for charging the battery.

Next, a series of processes for executing the forced shutoff mode according to the human body detection when the charging device of the present invention is executing the standby mode or the charging mode will be described in detail with reference to FIG. 6.

FIG. 6 is a flowchart illustrating a process of executing a forced shutoff mode when a human body is detected in a danger area preset on the charging device side of the present invention.

Referring to FIG. 6, while the charging device is executing the standby mode or the charging mode (step 602), the control block 108 checks whether a human body entry detection signal is input from the human body sensor 106 (step). 604). That is, the human body sensor 106, which may be installed at four corners of both sidewalls of the charging structure 304 on which the transmitters 122 and 126 are mounted, detects a human body entering a preset danger area.

If the human body entry detection signal is input as a result of the check in step 604, the control block 108 determines whether the current mode is a charging mode or a standby mode, and if the determination result is the standby mode, the process is performed in step 610. In the case of the charging mode, the control block 108 forcibly stops the charging mode through the output control of the power supply block 118 (step 608), and then the process proceeds to step 610. .

That is, the control block 108 executes the forced shut-off mode during a situation where a person entering the preset dangerous zone does not leave the dangerous zone, that is, the forced shut-off mode that does not execute the charging mode even when the vehicle is driven in the charging zone in the charging structure. Is executed (step 610).

Subsequently, the control block 108 controls the display block 112 and the alarm 114 to display the audiovisual warning, that is, the display of the warning text and the flashing of the forced shut-off state by the person entering the dangerous area. Generate an alarm sound (step 612).

Next, the control block 108 checks whether or not a human body entry release signal is input from the human body sensor 106 (step 614). As a result of the check here, a person who enters the dangerous area exits the dangerous area. If it is determined that, the control block (1) switches the forced block mode to the previous mode (step 616). That is, when the previous mode is the standby mode, the mode is switched to the standby mode, and when the previous mode is the charging mode and the vehicle is still driving the charging zone, the mode is changed to the charging mode. In case of departure, it goes to standby mode.

Therefore, the charging device of the present invention can automatically switch the standby mode or the charging mode to the forced shut-off mode when a person enters the danger zone, thereby effectively preventing personnel accidents that may occur when the vehicle battery is wirelessly charged. have.

Next, a series of processes for performing the charging process according to the charging of the battery mounted on the vehicle using the charging device of the present invention will be described in detail with reference to FIG.

7 is a flowchart illustrating a process of executing a charging process according to charging a vehicle battery using the charging device of the present invention.

Referring to FIG. 7, while the charging device is executing the standby mode (step 702), the control block 108 checks whether a vehicle entrance detection signal is input from the entrance detection sensor 102 (step 704).

As a result of the check in the step 704, when the vehicle entry detection signal is input, the control block 108 generates a control signal for operating the camera and transmits it to the image acquisition block 110, and as a result The camera is activated to photograph the vehicle license plate of the vehicle entering the charging zone in the charging structure (step 706).

Thereafter, the image acquisition block 110 recognizes the vehicle number from the photographed vehicle license plate image and transfers the recognized vehicle number to the control block 108 (step 708).

Again, the control block 108 checks whether the departure detection signal from the departure detection sensor 104 is input, that is, whether the vehicle traveling the charging zone in the charging structure is leaving the charging zone (step 710). ).

As a result of the check in the step 710, when the vehicle departure detection signal is input, that is, when the vehicle leaves the charging zone in the charging structure, the control block 108 uses the recognized vehicle number and charging date and time information as the charging information. 116. (Step 712).

Thereafter, the control block 108 retrieves the charging information stored in the memory block 116 and transmits the charging information to the remote charging server through the communication block 130 and the communication network (step 714). Each charging may be performed or may be performed at a predetermined periodic interval (eg, daily, weekly, monthly, etc.). Here, charging for charging the battery may be performed in units of charging times or in units of charging time (that is, driving time of the charging zone).

In the above description has been described by presenting a preferred embodiment of the present invention, but the present invention is not necessarily limited to this, and those skilled in the art to which the present invention pertains within a range without departing from the technical spirit of the present invention It will be readily appreciated that branch substitutions, modifications and variations are possible.
