Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. The sizes and shapes of the components shown in the drawings may be exaggerated for clarity and convenience. In addition, terms defined in consideration of the configuration and operation of the present invention may be changed according to the intention or custom of the user, the operator. Definitions of these terms should be based on the content of this specification.

1 is a schematic view showing a vehicle charging apparatus of the present invention.

The vehicle charging apparatus shown in FIG. 1 may include a power module 110, a kiosk 130, and a controller 150.

The power module 110 may provide charging power directly input to the vehicle 90.

The kiosk 130 may be provided with a power line 190 connected to the vehicle. The kiosk 130 may be electrically connected to the power module 110 and may be provided in plurality.

The control unit 150 may be provided in the power module 110 and may sequentially distribute the charging power to each kiosk 130.

According to the present invention, the power module 110 and the kiosk 130 may be formed separately from each other. At this time, a plurality of kiosks 130 may be connected to one power module 110. The control unit 150 provided in the power module 110 can sequentially distribute the charging power provided to each kiosk 130. [

According to the sequential control method of the control unit 150, even if the kiosk 130 connected to the power module 110 is added, there is an advantage that control can be performed without difficulty. Accordingly, each kiosk 130 can be easily added to a position desired by the user.

For example, the plurality of kiosks 130 can be spaced apart from each other in accordance with the parking position of each vehicle in a space where a plurality of vehicles can park. At this time, if the charging power of the power module 110 is provided to any one of the kiosks 130 by the control unit 150, the remaining kiosks 130 may not be provided with the charging power. At this time, if a larger number of kiosks 130 are required, it is sufficient to add the kiosk 130 to the empty space and electrically connect the kiosk 130 to the power module 110.

The control unit 150 for sequentially distributing the charging power may supply the charging power to only one first kiosk 130 selected in a state where the vehicles are connected to the plurality of kiosks 130. [ The controller 150 may provide charging power only to the selected one of the remaining kiosks 130 when charging of the first vehicle connected to the first kiosk 130 is completed. According to this, charging power can be provided only to one kiosk 130 at a point in time.

Thus, even if the second vehicle is connected to the second kiosk 130 while the charging of the first vehicle is in progress, the connection between the second vehicle and the second kiosk 130 has no effect on the charging of the first vehicle . Thus, the charging of the first vehicle can be completed at a predetermined time, so that the satisfaction of the first vehicle user can be improved.

The second vehicle can be parked at another place where the second kiosk 130 is provided without having to wait until the seat of the first kiosk 130 charging the first vehicle is vacant. Thereafter, when the power line 190 of the second kiosk 130 is connected to the second vehicle, the control unit 150 may proceed to charge the second vehicle after completion of charge of the first vehicle. Thus, the satisfaction of the second vehicle user can also be improved, since the second vehicle user can go to another vehicle without having to wait for the second vehicle to be charged.

The greater the number of kiosks 130 to satisfy all of a plurality of users, the more advantageous. The most ideal example may be that the kiosk 130 is installed at every parking place in the parking lot.

For example, in a parking lot where 100 vehicles can park, it is recommended that 100 kiosks (130) be provided for each parking spot.

According to the present invention, the charging power directly input to the vehicle can be provided from the power module 110. [ For example, the power module 110 may be provided with a conversion unit 111 for converting AC power supplied from a commercial power source into DC power required by a vehicle. The DC power output from the converter 111 may correspond directly to the charging power input to the vehicle.

Since the conversion unit 111 is provided in the power module 110, it suffices that the kiosk 130 includes only the power line 190 connected to the vehicle and the means for relaying the charging power. Accordingly, the kiosk 130 of the present invention can be manufactured in a compact size using a low production cost. The low-cost small kiosk 130 can be readily installed for each parking space.

As a comparative example, it is assumed that a converter 50 for converting AC power to DC power is provided in the charging stand 30 corresponding to the kiosk 130 of the present invention.

2 is a schematic view showing a vehicle charger of a comparative example.

The charging stand 30 is provided with a converter 50 for converting AC power into DC power required by the vehicle, so that the charging stand 30 can be directly connected to an external power source.

The installation of the converter 50 increases the volume, weight, and production cost of the charging stand 30. Since the external power can not be used infinitely due to the load allowed by the external power source, the number of the charging stand 30 is limited to a few I can not help it.

In order to use a single charging station 30 installed in a limited number, a plurality of vehicles have to line up in order. At this time, the user of the waiting vehicle must always wait in the vehicle because he does not know when the preceding vehicle will leave. According to this, the user complains about the difficulty of charging the vehicle, and the supply of the electric car naturally becomes limited. However, according to the present invention, since the kiosk 130 can be installed as easily as the parking lot number of the parking lot, there is no difficulty in charging.

Returning back to FIG. 1, according to the present invention, an environment can be provided in which a plurality of vehicles are parked in a parking space without lining up, thereby performing charging. At this time, it is necessary to decide from which vehicle to carry out the charging.

In one example, charging may be accomplished in the order that they are connected to the kiosk 130.

The kiosk 130 may transmit the time information connected to the power line 190 to the control unit 150. [

The control unit 150 can collect the time information obtained from the plurality of kiosks 130. The controller 150 may provide the charging power to the senior kiosk 130 providing the earliest time information. The controller 150 may provide the charging power to the next-generation kiosk 130 providing the quickest time information after the senior kiosk 130 when the power line 190 of the senior kiosk 130 is separated from the vehicle. According to the present embodiment, charging is started from a vehicle connected to the power line 190 of the first kiosk 130 among the plurality of vehicles. When charging of the vehicle is completed, Can be charged.

The kiosk 130 and the power module 110 may be spaced apart from one another. A supply line 180 may be provided in the vehicle charging apparatus of the present invention for connecting the kiosk 130 and the power module 110 to each other.

The supply line 180 may electrically couple the kiosk 130 and the power module 110.

A plurality of kiosks 130 may be arranged by the supply line 180 at intervals such that the vehicles may park at locations spaced apart from the power module 110. The electrical connection between the kiosk 130 and the power module 110 may be determined by the power module 110 of the kiosk 130, the supply line 180, and the power module 110. According to the present embodiment, electric power is supplied only to the kiosk 130 and the supply line 180 electrically connected to the vehicle in which charging is in progress, and no power is supplied to the remaining kiosk 130 and the remaining supply line 180 State can be maintained. Therefore, standby power consumed in the remaining kiosk 130 and the supply line 180 can be shut down at the source.

3 is a block diagram showing a vehicle charging apparatus of the present invention.

The supply line 180 for electrically connecting the kiosk 130 and the power module 110 may be connected to the power module 110 in parallel in accordance with the number of the kiosks 130.

The power module 110 may include a conversion unit 111 and a relay unit 113.

The converting unit 111 can convert the AC power supplied from the commercial power source into the DC power required by the vehicle. A large current is required in order to achieve rapid charging in which the vehicle is charged in a short time, and a plurality of conversion units 111 may be connected in parallel to provide a large current. The operation state of the conversion unit 111 can be monitored by the control unit 150. [

A residual current device (RCD) 116 may be provided between the converter 111 and the commercial power supply. The RCD may be used in an AC load to shield the first source line 170 when a residual current between the first source line 170 connecting the commercial power source and the power module 110 and the NEUTRAL is detected .

The relay unit 113 is interposed between the supply line 180 and the conversion unit 111 and can be controlled by the control unit 150. The relay part 113 may be provided with a relay interposed between the supply lines 180 and the conversion part 111 according to the number of the supply lines 180.

A relay is a device that acts to open or close an electrical circuit in response to various input signals such as voltage, current, power, frequency, etc., as well as temperature and light. Contact relays such as electromagnetic relays and solid-state relays such as semiconductor relays (transistor relays and SCR relays) are categorized into physical relays used when switching input signals into and out of a circuit. In addition, , A balance relay, a reed switch, and a wire spring relay.

Only the first relay selected by the control unit 150 among the plurality of relays may be turned on to be electrically connected to the conversion unit 111. [ At this time, the remaining relays may be turned off to be electrically disconnected to the converter 111. The DC power output from the conversion unit 111 may be provided to the first vehicle electrically connected to the first relay through the kiosk 130. [ The vehicle electrically connected to the remaining relays may be disconnected from the electrical connection with the converter 111 by turning off the remaining relays until the charging of the first vehicle is completed.

The control unit 150 and each relay may be connected by a control line 70. The control unit 150 may transmit the respective relay roll control signals through the control line 70.

The MCCB 117 and the SMPS 118 may be provided in the power module 110 for the operation of the controller 150. [

MCCB (Mold Case Current Breaker) is a circuit breaker for wiring, which is also called NFB (No Fuse Breaker) and can cut over current and short circuit current.

The MCCB is an assembly that integrates an opening / closing mechanism, a trip device, etc. in an insulating container and can open or close the energized state by manual or electrical operation. It also automatically cuts off the current when an overload or disconnect occurs. . A circuit breaker for wiring is a mold case circuit breaker used for protection of low-voltage indoors under AC 600V or DC 250V or less. It is also commonly referred to as NFB. Since it is compact, safe to operate, and does not have the burden of fitting a fuse, it is widely used instead of a combination of a conventional knife switch and a fuse. The trip device is a thermo type (bimetal is heated by the current flowing through the circuit breaker and trips because it is curved), the coil is operated by sucking the iron piece by the current through the current, thermal coin and electronic . The tripping characteristic does not trip even when 100% of the rated current is continuously energized, and the operating time for 125% and 200% of the rated current is separately determined.

A switched mode power supply (SMPS) is a power supply, which uses a switching control method to convert AC power to DC power using switching transistors.

This is a DC stabilized power supply device that stabilizes the output by controlling the on-off time ratio of a semiconductor switch element. It is highly efficient, compact and lightweight, and is widely used in most electronic equipment and equipment.

Depending on the quality of the power supply, stability and precision of electronic circuit operation are often influenced. In general, there are a series regulator method and a switched mode method in which a stable power source is converted from a battery and a commercial AC power source. The linear control method used in a TV set or a CRT monitor has a drawback in that the surrounding circuit is simple and the price is low, but the heat generation is large, the power efficiency is low, and the bulky is large. On the other hand, the switching mode method has a disadvantage in that it is expensive, the circuit is complicated, the output noise caused by the high frequency switching and the generation of electromagnetic waves are large, but it has a merit of having little heat generation, high power efficiency and small volume.

DC power is required for the operation of the control unit 150. The SMPS can convert AC power of 220V or the like supplied from an external power source into DC power and provide it to the controller 150. The external power input to the conversion unit 111 may be 380 V AC power and the SMPS may be connected to the second source line 80 to the external power different from the external power supplied to the conversion unit 111 Lt; / RTI > An MCCB may be interposed between the SMPS and the second source line 80.

The kiosk 130 is provided with at least one of a CT (Current Transformer) 133 and a PT (Potential Transformer) 131 for monitoring abnormality of the charging power supplied from the power module 110 . The charging power provided to the kiosk 130 may be delivered directly to the vehicle via the power line 190 without being separately processed in the kiosk 130. [ Accordingly, the supply line 180 and the kiosk 130 connected to the off-relays can charge the charging power without a waste of standby power.

Measuring the charging power of high voltage directly with a voltmeter is both dangerous and very uneconomic from the standpoint of voltmeter insulation. Therefore, a transformer with a secondary side of 100V is usually used. The transformer used for this purpose is called PT.

CT is intended to economically measure the current of charge power corresponding to high currents similar to PT.

When the CT and the PT are excluded, the power line 190 and the supply line 180 can be directly connected.

The kiosk 130 may be provided with a display (not shown) for indicating a charging state that the user can visually confirm. In addition, the kiosk 130 may be provided with a controller 135 for controlling the display and for monitoring the charging power.

The MCCB 137 and the SMPS 138 may be provided in the kiosk 130 to provide the driving power of the controller 135. [ The MCCB 137 and the SMPS 138 of the kiosk 130 perform functions similar to the MCCB 117 and the SMPS 118 of the power module 110 and provide DC power to the controller 135 and provide abnormal power Can be blocked. A second source line 80 may be coupled to the MCCB 137 of the kiosk 130.

A master 140 may be provided to manage a plurality of kiosks 130. The master 140 is a terminal provided in a management room or the like and can monitor each kiosk 130 by communicating with a controller 135 provided in each kiosk 130. The master 140 may be provided with a monitoring unit for communicating with each controller 135 and monitoring the kiosk 130, an MCCB 147 for providing power to the monitoring unit, and an SMPS 148.
