Figure 1 is a block diagram of an apartment complex parking convenience system according to an embodiment of the present invention.

The apartment parking convenience system includes a parking lot terminal group 200 and a parking guidance camera group 260. The parking lot terminal group 200 may be connected wirelessly or wired to the electric vehicle charging device 100 and the operation server 300. The parking lot terminal group 200 may be connected wirelessly or wired to the parking guidance camera group 260 and the emergency bell group 270.

The electric vehicle charging device 100 includes a charging controller 110. The charging controller 110 controls overall operations for charging an electric vehicle and controls communication with the parking lot terminal group 200 to transmit and receive data related to an authentication pass for charging and billing information. Transmission and reception of data related to the authentication pass and billing information of the charging controller 110 may be performed wirelessly or wired. The electric vehicle charging device 100 may be one of a fast charging device, a slow charging device, and an outlet device (a portable charging cable-only outlet or a billing-type outlet) that can be installed in each area of the parking lot.

A method by which the electric vehicle charging device 100 supplies power for battery charging to an electric vehicle may include a wired supply method and a wireless supply method. In the case of a wired supply method, an emergency charging cable or a mobile charging cable can generally be used in addition to a dedicated charging cable. The electric vehicle charging device 100 may include a card reader that reads the user ID (ID) from the user card to identify the user of the dedicated charging cable or emergency charging cable, or a communication unit that receives the user ID through the user's smart phone. . Here, the dedicated charging cable refers to a charging cable exclusively installed in a fast charging device or a slow charging device, and the emergency charging cable refers to a charging cable provided by the user or provided in a separate location to electrically connect to an outlet device. do.

The electric vehicle charging device 100 may include an RFID tag or QR code that stores information related to electric vehicle charging, and the information stored in the RFID tag may be read by a tag reader installed on the mobile charging cable.

The electric vehicle charging device 100 may include a switch driver that drives a charging switch in response to a driving control signal provided from the charging controller 110. When the charging switch is driven by the switch driver, charging power for charging an electric vehicle can be provided to an outlet.

In one embodiment, the electric vehicle charging device 100 may include a metering unit. The metering unit may generate metering data by measuring the amount of charging power for household billing when the emergency charging cable receives charging power through the outlet and charges the electric vehicle. The metering unit may be a mechanical or digital power meter. The metering unit may measure the amount of charging power using a current transformer installed in the charging power line.

Additionally, the electric vehicle charging device 100 may include a communication unit connectable to the charging controller 110. The communication unit may receive metering data from the metering unit through the charging controller 110. The communication unit may transmit the metering data to the outside and receive authentication confirmation information related to the portable charging cable from the outside. For example, the metering data may be provided to the operation server 300 through the parking lot terminal group 200. The operating server 300 may be just a server or a home network server. The operation server 300 can communicate with a wall pad installed as a household terminal in each household within the apartment complex.

The operation server 300 may be connected to the operator server through a communication channel that may be wired or wireless. The operator server may be a charging operator server connected to the mobile charging cable through a mobile communication network. When charging is performed through the mobile charging cable, the charging operator server may communicate with the operator's billing department to charge the charging fee through the mobile charging cable.

Meanwhile, the charge controller 110 of the electric vehicle charging device 100 can charge the electric vehicle through the emergency charging cable. In this case, charging for charging usage may be charged as a household charge. Household billing means that billing is done to individual households in the apartment complex where the user of the emergency charging cable belongs. Household charges are electricity usage charges that are separately charged for electric vehicles from the power supplied from the power receiving facilities of apartment complexes. Here, the household billing rate system is different from the household electricity use rate system that applies a progressive system, and is operated as a relatively cheap rate system based on electric vehicle charging.

Additionally, the charge controller 110 of the electric vehicle charging device 100 can charge the electric vehicle through the mobile charging cable. In this case, the billing may be a business billing that is separate from the household billing. Business billing is performed by the business billing department and is charged individually to users of the mobile charging cable. When electric vehicle charging is performed through the electric vehicle charging device 100 and business charges are made, the total household charge charged for the charging recognition device 100 that can be installed in the parking lot is calculated by subtracting the business charges. Because business billing is separate from household billing, the amount of power used through the mobile charging cable must be excluded from the overall household billing.

The charging controller 110 of the electric vehicle charging device 100 generates the drive control signal when the user ID of the emergency charging cable received through the card reader is authenticated to charge the electric vehicle and generate the metering data. Let it come true.

The charge controller 110 of the electric vehicle charging device 100 generates the drive control signal for a certain period of time when the user of the mobile charging cable attempts to charge the electric vehicle, so that the tag reader of the mobile charging cable is connected to the tag. A tag reading operation is performed for the mobile charging cable to establish a communication connection with the operator server.

The charging controller 110 of the electric vehicle charging device 100 continues to maintain the drive control signal when authentication confirmation information of the mobile charging cable is received through the communication unit after communication connection between the mobile charging cable and the business operator server. Thus, electric vehicle charging is performed using the portable charging cable.

In an embodiment of the present invention, the electric vehicle charging device 100 may enable electric vehicle charging through the emergency charging cable or mobile charging cable when there are inputs for electric vehicle charging authentication as described above.

In addition, the electric vehicle charging device 100 is operated through the emergency charging cable or the mobile charging cable when there is automatic authentication through the parking lot terminal group 200 even when there are no inputs for electric vehicle charging authentication as described above. Electric vehicle charging can be done. More specifically, the parking lot terminal group 200 receives image information of the vehicle provided from the parking guidance camera group 260, obtains parking guidance information and parking location confirmation information, and charges from the electric vehicle charging device 100. When a trial signal is received, it is automatically verified whether the electric vehicle attempting to charge is the resident's vehicle based on the parking guidance information and parking location confirmation information. Accordingly, when automatic authentication is successful, the electric vehicle charging device 100 can pass the authentication and perform charging for the electric vehicle using a charging method exclusively for residents (eg, household billing).

The parking guidance camera group 260 is installed in response to a plurality of license plate recognition cameras and a plurality of parking surfaces to recognize the license number of a vehicle entering the parking lot, and to search for an empty parking surface in the parking lot. may include parking guidance cameras. The parking guidance camera group 260 may be installed in a position where it can capture images of parking surfaces (for example, 6 parking surfaces or 12 parking surfaces) within the parking lot. The parking guidance camera group 260 may include a plurality of cameras including an image sensor, a system-on-chip, and a full tolerance display unit. The image sensor can capture images of parking surfaces defined in a parking lot by receiving them through an omnidirectional camera lens. The image sensor may be implemented as, for example, “Sony IMX291”. The omnidirectional camera lens may be implemented as a fisheye lens. The fisheye lens may be a lens that takes images of at least four or six parking surfaces. In another embodiment, the fisheye lens may be a lens that captures images of 12 parking surfaces. The system-on-chip captures and processes images of the parking surfaces captured through the image sensor, and may generate a full clearance display control signal indicating the parking status on the parking surfaces. The full tolerance display control signal may be generated using a binarized image obtained by converting the parked original image to gray scale and then binarizing the gray scale image. That is, the image within the target area within the binarized image can be used to determine whether or not there is an empty parking space. Whether or not to park on the parking surface can be determined by detecting edges within the target area in each of the current frame and the previous frame and comparing them. Accordingly, a full clearance display indicating whether the parking surface is empty or full can be implemented.

The vehicle number recognition unit, which may be included in the parking guidance camera group 260, may be installed at the entrance to the parking lot to recognize the registered vehicle number of the vehicle. The car number recognition unit can be implemented as a typical LPR device. The vehicle number recognition unit may provide the recognized vehicle number to the parking lot terminal group 200.

The emergency bell group 270 may be installed in the parking lot and include a plurality of emergency bells that generate an emergency call signal when activated. The emergency bell group 270 may be connected to the operation server 300 through the parking lot terminal group 200 or directly connected to the operation server 300 without going through the parking lot terminal group 200. Communication between the emergency bell group 270 and the parking lot terminal group 200 may be implemented as wired communication or short-distance communication.

The parking lot terminal group 200 may receive vehicle image information provided from the parking guidance camera group 260 and obtain parking guidance information and parking location confirmation information as parking-related information. The parking lot terminal group 200 may process and transmit the emergency call signal provided from the emergency bell of the emergency bell group 270. When a charging attempt signal is received from the electric vehicle charging device 100 installed in the parking lot, the parking lot terminal group 200 determines whether the electric vehicle making the charging attempt is the resident's vehicle by using the parking guidance information and parking location confirmation information, that is, the parking lot. Automatic authentication is performed based on related information, and when authentication is successful, authentication pass and resident-only charging through the electric vehicle charging device 100 can be performed for the electric vehicle. The parking lot terminal group 200 includes a plurality of parking lot terminals to perform the operations described above.

Each of the plurality of parking lot terminals may be installed in each parking zone of the parking lot. The parking lot terminal can obtain vehicle-related information and driver information by reading the vehicle card when a vehicle enters the parking lot and heads to an empty parking space or parking guidance destination. In addition, the parking lot terminal can acquire the vehicle-related information and the driver information by performing Bluetooth communication with the smart phone of the driver of the vehicle. The parking lot terminal may include a Bluetooth communication module to perform short-range wireless communication, such as Bluetooth communication. The driver's smart phone can perform a parking location confirmation operation within the parking lot when an application related to parking location confirmation is downloaded. Additionally, if necessary, the parking area where the electric vehicle charging device 100 is installed may be displayed on the screen of the driver's smart phone.

The parking location confirmation operation can be implemented by the smart phone determining the parking location of the vehicle and generating a parking location confirmation signal when the user who has parked the vehicle gets out of the vehicle and walks a few steps. In another case, parking lot terminals may generate a parking location confirmation signal by receiving and processing information from the smart phone.

When the smart phone downloads the parking guidance-related application, a navigation screen in the parking lot may be displayed. The route to the parking destination may be displayed on the navigation screen. The smart phone can provide vehicle-related information and driver information during Bluetooth communication. Additionally, the smart phone can provide information related to parking in a preferred parking area of a parking lot during Bluetooth communication. In the case where the smart phone is not carried by the driver or in the case of basic parking guidance control, parking guidance information is provided through the parking guidance electronic signboard or the parking guidance camera group 260 without providing parking guidance information through the smart phone. You can.

The Bluetooth module of the parking lot terminal can obtain the vehicle's license plate number or the driver's residence location information by performing Bluetooth communication with the smart phone. Additionally, the Bluetooth module of the parking lot terminal can receive an emergency call signal or diagnostic information provided from the emergency bell group 270.

In Figure 1, the parking lot terminal group 200 shows only one parking terminal for convenience of illustration. More specifically, one parking lot terminal belonging to the parking lot terminal group 200 may include an interface 210, a control unit 220, a communication unit 230, a storage unit 240, and a parking location determination unit 250. there is.

Referring to FIG. 3, in operation S301, the operation server 300 connected to the parking lot terminal group 200 may receive a vehicle number (vehicle license) from the vehicle number recognition unit of the parking guidance camera group 260. In operation S302, the operation server 300 may receive smart phone information of a passenger (eg, vehicle driver or passenger) from a communication device installed at the entrance of the complex, such as a complex entrance beacon device. In this case, the smart phone may already have the parking guidance application running or may be in the stage just before the parking guidance application is executed. The smart phone can provide at least one of the passenger information, such as vehicle information, phone number, and residence number information, through Bluetooth communication.

In operation S303, the operation server 300 may check whether the vehicle number received from the vehicle number recognition unit and the passenger information received from the smart phone match the same household. For example, assuming that the vehicle number of a resident of room 501, building 101 is 56ma2301 and the phone number is 010-257-1254, the vehicle number received from the license plate recognition unit is 56ma2301 and the phone number received from the smart phone is 56ma2301. If the number is 010-257-1254, the operation server 300 may determine that the received vehicle number and information on the smart phone belong to (match) the resident of room 501 in building 101.

In operation S304, the operation server 300 may transmit a parking guidance service switching command to the smart phone to provide parking guidance control in the parking lot. A parking guidance service switching command may be transmitted to a smart phone through the parking lot terminal group 200. The smart phone may display a parking lot navigation screen in response to the parking guidance service switching command. For example, a parking lot navigation screen may display a map of the parking lot and a route to the parking destination.

In operation S305, the operation server 300 checks whether the parking guidance control service is related to the target area. The target area is the parking destination where the vehicle driver wants to park. In another embodiment, the target area may include parking surfaces provided separately for charging electric vehicles. Among the plurality of parking surfaces in the parking lot, the vehicle driver can pre-register the parking surfaces corresponding to the target area through the app. When receiving a phone number from a smart phone, the operation server 300 can check whether the driver corresponding to the received phone number has set a target area. As another example, even when setting the target area is performed through a smart phone, the operation server 300 also receives setting information of the target area when receiving a phone number from the smart phone to determine whether it is a parking guidance control service related to the target area. You can check whether .

In the case of target area parking guidance, the process proceeds to operation S307 and the parking surface in the empty target area is set as the parking guidance destination. If the target area is not parking guidance, the process proceeds to operation S306 and the parking surface in the empty normal area is set as the parking guidance destination. It can be set as a destination. The operation server 300 can receive, retain, and manage empty parking space information in real time through the parking guidance camera group 260. Therefore, the parking guidance destination can be optimally set at that point in time based on the information on the empty parking space.

In operation S308, the operation server 300 may receive at least one of the smart phone information and the vehicle card information to determine the vehicle entry location within the parking lot. In order for the vehicle to go to the parking destination, it is necessary to determine whether the vehicle should go straight or turn left or right at an intersection in the parking lot, so it is necessary to determine the vehicle entry location in the parking lot. In the case where both a smart phone and a vehicle card exist, the accuracy of the vehicle entry location within the parking lot can be increased by using both the information on the smart phone and the vehicle card. Meanwhile, even when only one of the smart phone and the vehicle card is present, the vehicle entry location can be determined as a minimum. The operation server 300 may receive the vehicle entry location from the parking guidance camera group 260. Parking lot terminals in the parking lot terminal group 200 are installed in each section of the parking lot. The parking lot terminal in the parking lot terminal group 200 can perform Bluetooth communication with a smart phone. The parking lot terminal may receive a short-range wireless communication signal, such as a Bluetooth signal, transmitted from a smart phone to determine the vehicle entry location.

In operation S309, the operation server 300 may transmit parking guidance information to at least one of the smart phone and the parking guidance board (display board). The smart phone can receive the parking guidance information through the parking lot terminal group 200. For example, a parking lot navigation may be displayed on the screen of a smart phone, and the route to the parking destination may be displayed similarly to a normal navigation route display. The parking guidance board may be one of the guidance information units. On the parking guidance board, vehicle number information and direction information related to parking guidance can be visually displayed.

In operation S310, the operation server 300 checks whether the vehicle is proceeding in the direction of the parking guidance destination. Operation S310 can be performed through determination of the vehicle entry location described above.

In operation S311, the operation server 300 checks whether the vehicle has arrived at the parking guidance destination. Likewise, operation S311 can be performed through determination of the vehicle entry location described above.

In operation S312, the operation server 300 may notify the completion of parking guidance to at least one of the smart phone and the parking guidance board. The parking guidance application on the smart phone can be completed when the completion of parking guidance is notified by the smart phone. When the completion of parking guidance is announced to the parking guidance board, the parking guidance information displayed on the parking guidance board disappears.

The parking guidance control according to FIG. 3 has the advantage of being able to perform parking guidance through at least one of a smart phone and a parking guidance information unit, regardless of the presence or absence of a vehicle card.

Meanwhile, unlike operation S308, the operation server 300 may receive the vehicle number from the vehicle number recognition camera device in the parking lot and determine the vehicle entry location within the parking lot. The operation server 300 may receive the license plate number of a vehicle recognized at a parking lot intersection from the parking guidance camera group 260. Ultimately, the vehicle number recognized at this time is used to determine the vehicle's location information for parking guidance control. Vehicle number recognition cameras can be installed at each intersection where people go straight or turn left or right in the parking lot.

Of course, even in this case, if a smart phone and a vehicle card exist, the accuracy of the vehicle entry location in the parking lot can be increased by additionally using the information on the smart phone and the vehicle card. Meanwhile, even when information is not received from a smart phone or vehicle card, the vehicle entry location can at least be determined through vehicle number recognition at an intersection. In this case, parking guidance control has the advantage of being able to perform parking guidance even without a vehicle card.

Additionally, the operation server 300 may receive at least one of the vehicle number or vehicle card information received through vehicle identification and determine the vehicle entry location within the parking lot. By using both license plate recognition and vehicle card information, the accuracy of vehicle entry location within a parking lot can be increased. Meanwhile, even when only one of the license plate recognition camera and the vehicle card exists, the vehicle entry location can at least be determined. Parking guidance control according to this has the advantage of being able to perform parking guidance using only a vehicle card even without a smart phone.

Here, whether the vehicle passes can be achieved by confirming the entry location of the vehicle based on the BLE signal. The BLE signal may further include directional information to support a direction detection function as well as an RSSI signal. For example, the nRF52811 SoC, built on Nordic's nRF52 series platform, enables a wider range of applications to take advantage of the direction finding capabilities of Bluetooth 5.1 as well as wireless Internet of Things (IoT) features such as Thread and ZigBee. The directional information can be useful for recognizing the approaching or moving away of a vehicle to determine the vehicle's location without triangulation using only RSSI signal strength.

FIG. 4 is a flowchart illustrating the processing process of the emergency call signal according to FIG. 1 by way of example.

Referring to FIG. 4, in order to process an emergency call signal, the operation server 300 connected to the emergency bell group 270 checks whether there is information received from the emergency bell in operation S801.

When received information exists, in operation S802, the operation server 300 stores the received information in an internal data buffer.

In operation S803, the operation server 300 checks whether an emergency call signal is detected in the received information stored in the data buffer.

When an emergency call signal is detected, the operation server 300 switches the operation mode to the intensive monitoring mode in operation S804. Accordingly, intensive CCTV monitoring is performed, and the CCTV storage device stores images of the surrounding area where the emergency bell was pressed.

In operation S805, the operation server 300 transmits an ACK signal indicating receipt of an emergency call signal to the emergency bell group 270.

In operation S806, the operation server 300 checks whether an emergency release input exists.

When there is an emergency release input through a keyboard or other input means, the operation server 300 switches the operation mode from the intensive monitoring mode to the general monitoring mode in operation S807.

If there is no emergency release input, the operation server 300 counts the automatic recovery time in operation S808.

In operation S809, the operation server 300 checks whether the counted automatic recovery time exceeds the maximum time value. If the automatic recovery time does not exceed the time maximum value, the operation returns to operation S806. If the automatic recovery time exceeds the time maximum value, the operation proceeds to operation S807.

If an emergency signal is not detected in operation S803, this may mean performing a self-diagnosis operation mode. The self-diagnosis mode starts with operation S810.

In operation S810, the operation server 300 extracts the emergency bell ID and charging voltage value from the stored received information and stores them in the DB.

In operation S811, the operation server 300 checks whether the charging voltage value is below the reference value.

If the charging voltage value is below the reference value, in operation S812, the operation server 300 notifies the inspection or replacement of the emergency bell battery through data communication or an alarm.

In operation S813, the operation server 300 stores the time at which the emergency bell ID and charging voltage value were input in the DB.

As described above, FIG. 4 illustrates an operation of the operation server 300 in response to an emergency call signal and an operation of performing self-diagnosis.

FIG. 5 is a block diagram showing a wired connection between the electric vehicle charging device according to FIG. 1 and the electric vehicle.

Referring to FIG. 5 , the electric vehicle 20 may receive charging power from the power socket 40 through the charging cable 30 . The charging cable 30 may be configured to include at least one of a charging connector 31, an outlet socket connection part 33, and an in-cable control box (ICCB) 32.

According to some embodiments of the present invention, wired charging of an electric vehicle may be performed by connecting the charging cable 30 between the plug connection port 21 of the electric vehicle 20 and the power socket 40 of the electric vehicle charging device 100. You can. The charging cable 30 may correspond to the above-described dedicated charging cable, but is not limited thereto, and of course, the charging cable 30 may be replaced with the above-described emergency charging cable or mobile charging cable.

Here, the electric vehicle 20 can generally be defined as a vehicle (automobile) that supplies power provided from a rechargeable energy storage device, such as a battery, as an energy source for an electric motor, which is a power device. In addition, the electric vehicle 20 may include a hybrid vehicle having both an electric motor and a general internal combustion engine, and may include not only an automobile, but also a motorcycle, a cart, and a scooter. ) and electric bicycles.

Additionally, the electric vehicle 20 applied to the present invention may include a plug connection port 21 so that the battery can be charged by wire. In this case, the electric vehicle 20 whose battery can be charged by wire may be referred to as a plug-in electric vehicle (PEV). Additionally, the plug connector 21 provided in the electric vehicle 20 according to the present invention can support slow charging or fast charging. In this case, the electric vehicle 20 may support both slow charging and fast charging through one plug connection port, or may include separate plug connections supporting slow charging and fast charging. Additionally, the electric vehicle 20 to which the present invention is applied may include an on-board charger to support slow charging or charging using AC power supplied from a general power system. The onboard charger can boost AC power supplied externally by wire during slow charging, convert it into DC power, and supply it to the battery built into the electric vehicle 20. Therefore, when AC power for slow charging is supplied to the plug connection port 21 of the electric vehicle 20, charging can be performed through an on-board charger, and when direct current power for fast charging is supplied to the plug connection port 21. Charging can be performed without going through the onboard charger.

The charging connector 31 may be a connection part that can be electrically connected to the electric vehicle 20, and the in-cable control box (ICCB) 32 communicates with the electric vehicle 20 to connect the electric vehicle 20 to the electric vehicle 20. Status information can be received or power charging to the electric vehicle 20 can be controlled. Here, the in-cable control box 32 is shown as being included in the charging cable 30, but is not limited thereto and may be mounted in a location other than the charging cable 30, coupled to the SECC, or replaced with the SECC. Here, the outlet socket connection portion 33 may be connected to the power socket 40 that receives power. For example, the power socket 40 may refer to an outlet previously installed in various places, such as an apartment parking lot for a user of the electric vehicle 20 or a parking area of a building. In addition, the charging procedure is performed by communicating with the in-cable control box 32 or one of the components (e.g. EVCC) of the electric vehicle 20 in a building or place (e.g. a stand) where the power socket 40 is installed. A device that controls may be installed, and this device may be referred to as SECC (Supply Equipment Communication Controller). Here, the SECC can communicate with a power grid or an infrastructure management system that manages the power grid, a management server (only server) of a building where the power socket 40 is installed, or an infrastructure server through wired or wireless communication. .

Here, the power socket 40 can directly supply AC power from the power system. For example, it can supply AC power corresponding to at least one of 1P2W (single-phase, 2-wire) and 3P4W (3-phase, 4-wire). The electric vehicle charging cable 30 supports slow charging and can supply power for slow charging to the electric vehicle 20. In this case, power between 3 kWh and 14 kWh can be supplied to the electric vehicle 20 as a slow charging power amount. In addition, the electric vehicle charging cable 30 supports fast charging and can supply power for fast charging to the electric vehicle 20. In this case, the fast charging power amount between 50 kWh and 100 kWh can be supplied to the electric vehicle 20.

Meanwhile, in the electric vehicle charging system according to FIG. 5, in the case of electric vehicle users who are not residents, a method of attaching an RFID tag containing location information to the power socket 40 and charging through this may be provided. More specifically, the ICCB (32) recognizes the RFID tag and transmits the location and power amount to an external server through the 4G or 5G communication module located inside the ICCB (32), so that the user can be charged an electric vehicle fee. there is. Additionally, a method of charging may be provided by using the GPS function in the user's smartphone to recognize the location of the charging station. More specifically, a method in which the smart phone recognizes the location of the charging station and transmits the amount of power to the corresponding server by wirelessly communicating with the ICCB (32) can also be used.

FIG. 6 is a flowchart illustrating a process for quickly supporting electric vehicle charging based on parking guidance and parking location confirmation information obtained according to FIG. 1.

Operations S1201 to S1213 of FIG. 6 are described as being performed by the control unit 220 in the parking lot terminal group 200 of FIG. 1, but are not necessarily limited thereto.

Referring to FIG. 6, the parking lot terminal group 200 may perform parking guidance in operation S1201. The performance of parking guidance may be the same or similar to that described above with reference to FIG. 3 . When performing parking guidance, parking areas accessible to the electric vehicle charging device 100 of FIG. 1 may be displayed on the user's smartphone screen. The user's smart phone is activated when entering the parking lot through the app, and parking areas accessible to the electric vehicle charging device 100 that is not in charging state may be displayed. In operation S1202, the parking lot terminal group 200 is parked. Location confirmation can be performed. Parking location confirmation is performed by recognizing which vehicle is parked in which parking area of the parking lot, and this may also be the same or similar as described above.

In operation S1203, the parking lot terminal group 200 may check whether the emergency bell signal is received when relaying the emergency bell signal. When an emergency bell signal is received, the parking lot terminal group 200 may perform CCTV monitoring and an emergency bell alarm operation in operation S1204.

In operation S1205, the parking lot terminal group 200 may check whether there is a request for charging an electric vehicle. An electric vehicle charging request may be provided from the charge controller 110 of the electric vehicle charging device 100 of FIG. 1 . For example, in the charge controller 110 of FIG. 1, the charging cable 30 described in FIG. 5 is connected between the plug connection port 21 of the electric vehicle 20 and the power socket 40 of the electric vehicle charging device 100. In this case, the electric vehicle charging request can be transmitted to the parking lot terminal group 200. Additionally, the electric vehicle charging request may occur even when the above-described dedicated charging cable, emergency charging cable, or mobile charging cable is connected to the electric vehicle charging device 100.

In one embodiment, when there are inputs (card reading information input or authentication confirmation information reception of a mobile charging cable) for electric vehicle charging authentication as described above through the electric vehicle charging device 100, the operations after operation S1205 are performed. It may be omitted. That is, in this case, the electric vehicle can be charged through the dedicated charging cable, the emergency charging cable, or the mobile charging cable through a general authentication method.

Meanwhile, in the case where there are no inputs (card reading information input or authentication confirmation information reception of the mobile charging cable) for electric vehicle charging authentication as described above through the electric vehicle charging device 100, automatic authentication is performed through the parking lot terminal group 200. Since this needs to be performed, operations after operation S1205 can be performed. In the end, the operations following operation S1205 are operations premised on automatic authentication based on parking-related information through the parking lot terminal group 200.

In operation S1206, the parking lot terminal group 200 may compare the parking location confirmation information and the device ID of the electric vehicle charging device 100. For example, if the parking location confirmation information where the resident's electric vehicle is parked matches the device ID of the electric vehicle charging device 100 installed in the parking lot, it may be determined that the user of the resident vehicle is attempting charging. Parking area information may be matched in advance with the device ID of the electric vehicle charging device 100 and stored. That is, the device ID of one electric vehicle charging device 100 may be matched in advance to information on one or more parking zones near where the electric vehicle charging device 100 is installed. Therefore, if the parking location confirmation information does not match the device ID of the electric vehicle charging device 100 installed in the parking lot, automatic authentication for charging will be determined to fail. Meanwhile, even if the parking location confirmation information where the vehicle is parked matches the device ID of the electric vehicle charging device 100, if the parking location confirmation information was generated by a non-resident's vehicle, the non-resident's electric vehicle (or the resident's unauthorized electric vehicle) It may be determined that the user is attempting to charge.

In operation S1207, the parking lot terminal group 200 may check whether a charging request from the occupied vehicle has been generated. Ultimately, by performing operation S1206, the charging authentication check in operation S1207 is automatically performed without requiring a separate input operation by the user.

When it is determined that a charging request from the resident vehicle has been generated, in operation S1209, the parking lot terminal group 200 provides charging approval information and controls the start of charging using a charging method exclusively for the resident. Accordingly, the charging controller 110 of the electric vehicle charging device 100 of FIG. 1 may recognize that charging is approved in response to receiving charging approval information and provide charging power to the electric vehicle 20. Therefore, when a request for charging an electric vehicle is made by a resident, charging approval is automatically made based on parking guidance and parking location confirmation information. Therefore, when a resident requests charging, charging approval by manipulation input or charging approval through a data storage medium is not required, so electric vehicle charging is quickly supported.

Meanwhile, when it is determined that a charging request from a non-occupied vehicle has been generated, in operation S1208, the parking lot terminal group 200 controls the start of charging using a visitor-only charging method without separately performing charging approval. In this case, charging approval may be achieved by manual input from the visitor. In other words, the visitor can receive authentication for charging approval by directly entering the visitor's unique information on the touch screen of the electric vehicle charging device 100 or by inserting or using a credit card, check card, visitor card, or mobile device. there is. Accordingly, the charging controller 110 of the electric vehicle charging device 100 of FIG. 1 may recognize that charging according to the visitor's charging request has been approved and provide charging power to the electric vehicle 20.

In operation S1210, the parking lot terminal group 200 may check whether a charging end event has occurred. The charging end event may occur when the charging cable 30 described in FIG. 5 is disconnected between the plug connection port 21 of the electric vehicle 20 and the power socket 40 of the electric vehicle charging device 100. Additionally, a charging termination event may occur when the voltage of the battery being charged in the electric vehicle reaches the charging limit reference voltage. Additionally, a charging termination event may occur when overcurrent, overheating, or other abnormalities are detected during the charging process.

When a charging termination event occurs, in operation S1211, the parking lot terminal group 200 receives the charging power amount of the electric vehicle and the device ID of the electric vehicle charging device 100 from the electric vehicle charging device 100 and transmits it to the operation server 300. You can.

In operation S1212, the parking lot terminal group 200 may receive billing information from the operation server 300 operated in the apartment complex.

In operation S1213, the parking lot terminal group 200 can display the charging power amount and billing information as needed and transmit it to the electric vehicle, the user's registered smart phone, or the wall pad of the corresponding household. The charging power amount and billing information can be transmitted to the operation server 300 and the multiple connected wall pads of the corresponding household. Additionally, the charging power amount and billing information can also be transmitted to the smartphone corresponding to the charging user. Of course, in this case, the smart phone can receive the charging power amount and billing information by executing the application and performing Bluetooth low energy (BLE) communication with the parking lot terminal group 200.

Therefore, electric vehicle charging can be quickly supported to residents based on information on parking guidance and parking location confirmation by using existing parking convenience resources that perform parking guidance and parking location confirmation without adding facilities for charging electric vehicles.

Figure 7 is an example diagram of an electric vehicle charging operation table used in the electric vehicle charging support process of Figure 6.

Referring to FIG. 7, in the case of parking guidance, the vehicle number and occupant ID may be stored as shown in the AR10 area. For example, when the vehicle of a resident living in room 501 of building 101 of the apartment complex enters the parking lot, the vehicle number may be stored as 127, 8485 and the phone number may be stored as 010-5675-1010. Additionally, for example, when the vehicle of a resident living in room 603 of Building 105 enters the parking lot, the vehicle number may be stored as 128, 9269 and the phone number may be stored as 010-2222-1254. Meanwhile, when a non-resident, for example, a visitor's vehicle enters the parking lot, only the vehicle number can be stored in the AR10 area.

In the case of parking location, parking zone information may be stored as shown in area AR20. For example, if the vehicle of a resident living in room 501 of building 101 is parked in area 301 A on the 2nd basement floor, the parking area information with the confirmed parking location may be stored as F2A-301. Additionally, when the vehicle of a resident living in room 603 of building 105 is parked in area B 202 on the 3rd basement floor, the parking area information with the confirmed parking location can be stored as F3B-202.

Meanwhile, in the case of an emergency bell, information on the location of the emergency signal generation can be stored as shown in the AR30 area. For example, when an emergency signal is generated from an emergency bell installed in area 101 A on the second basement floor, information on the location of the emergency signal generation can be stored as F2A-101. Additionally, when an emergency signal is generated from an emergency bell installed in area C 402 on the 3rd basement floor, information on the location of the emergency signal generation can be stored as F3C-402.

In the case of electric vehicle charging, the device ID and charging location information of the electric vehicle charging device may be stored as shown in the AR40 area. For example, when a charging request signal is generated from an electric vehicle charging device installed in area 301 A on the second basement floor, the device ID of the electric vehicle charging device is EC2 and the charging location information can be stored as F2A-301. Therefore, in this case, if the parking area information confirmed as F2A-301 in the AR20 area and the charging location information stored as F2A-301 in the AR40 area match each other and room 501 of building 101 in the AR10 area matches, this is 501 It may be determined by the parking lot terminal group 200 that the resident of the house requests an attempt to charge the electric vehicle. Therefore, residents with electric vehicles can automatically receive charging approval without requiring cumbersome operation input for charging approval.

Meanwhile, when a charging request signal is generated from the electric vehicle charging device installed in area B 205 on the 3rd basement floor, the device ID of the electric vehicle charging device is EC9 and the charging location information can be stored as F3B-205. Therefore, in this case, the parking area information confirmed as parking location as F3B-202 in the AR20 area and the charging location information stored as F3B-205 in the AR40 area are not exactly the same, but they fit each other, and 603 in Building 105 in the AR10 area. If the calls are matched, the parking lot terminal group 200 may determine that the resident of room 603 is requesting an attempt to charge the electric vehicle. More specifically, information on the charging location where the electric vehicle charging device is installed may correspond to information on a plurality of parking zones. In other words, one electric vehicle charging device can cover the charging of an electric vehicle parked in any one of about 6 to 12 parking zones.

FIG. 8 is a flowchart illustrating another process for quickly supporting electric vehicle charging based on parking guidance and parking location confirmation information obtained according to FIG. 1.

In FIG. 8, operations S1301 and S1302 provided in addition to operations S1201 to S1213 of FIG. 6 are described as being performed by the control unit 220 in the parking lot terminal group 200 of FIG. 1, but are not necessarily limited thereto.

The control processes in FIG. 8 exemplarily show processes that require authentication from residents and support charging when a special event occurs. Unlike the case of FIG. 6, an event may occur in which two electric vehicles are parked in each parking area at substantially the same time and then attempt to charge. In this case, automatic authentication is not performed specifically for charging approval, and ID authentication of the occupant attempting charging is required.

Therefore, in addition to the operations of FIG. 6, operations S1301 and S1302 are additionally provided.

In operation S1301, the parking lot terminal group 200 checks whether a plurality of electric vehicles are parked in parking areas within a specific range.

When a plurality of electric vehicles are parked and a charging request is made, in operation S1302, the parking lot terminal group 200 receives the ID of the charging requester and performs authentication without performing automatic authentication. Here, the person requesting charging may be a resident or a non-resident. Receiving ID from a charging requestor can be accomplished through various methods. For example, the person requesting charging can directly input the visitor's unique information on the touch screen of the electric vehicle charging device 100 according to the input instructions. Direct input can be achieved by the charging requestor directly touching the touch screen or by the charging requestor pressing the ten keys, function keys, and character keys.

Additionally, the charging requestor may provide the charging requestor's ID by inserting a resident card, credit card, or check card into the reader. Additionally, the charging requestor can receive authentication for charging by providing the charging requestor's ID through communication using the Bluetooth function of the smart phone.

Meanwhile, since operations S1201 to S1213 shown in FIG. 8 are the same as operations S1201 to S1213 shown in FIG. 6, further description is omitted to avoid duplication.

FIG. 9 is an example diagram of an electric vehicle charging operation table used in the electric vehicle charging support process of FIG. 8.

Referring to FIG. 9, in the case of parking guidance, the vehicle number and occupant ID may be stored as shown in the AR11 area. For example, when the vehicle of a resident living in room 501 of building 101 of the apartment complex enters the parking lot, the vehicle number may be stored as 127, 8485 and the phone number may be stored as 010-5675-1010. Additionally, for example, when the vehicle of a resident living in room 101 of Building 105 enters the parking lot, the vehicle number may be stored as 128, 9269 and the phone number may be stored as 010-2222-1254. Additionally, for example, when the vehicle of a resident living in room 502 of Building 105 enters the parking lot, the vehicle number may be stored as 127, 8484 and the phone number may be stored as 010-3484-2849.

In the case of parking location, parking zone information may be stored as shown in area AR21. For example, if the vehicle of a resident living in room 501 of building 101 is parked in area 301 A on the 2nd basement floor, the parking area information with the confirmed parking location may be stored as F2A-301. Additionally, if the vehicle of a resident living in room 101 of building 101 is parked in area A 301 on the second basement floor, the parking area information of the confirmed parking location can also be stored as F2A-301. Here, even if the parking zone information is the same, the actual parking locations may correspond to parking surfaces that are adjacent to or nearby each other. Meanwhile, if the vehicle of a resident living in room 502 of building 101 is parked in area 302 A on the second basement floor, the parking area information with the confirmed parking location can be stored as F2A-302.

Meanwhile, in the case of an emergency bell, information on the location of the emergency signal generation can be stored as shown in the AR31 area. For example, when an emergency signal is generated from an emergency bell installed in area 101 A on the second basement floor, information on the location of the emergency signal generation can be stored as F2A-101. Additionally, when an emergency signal is generated from an emergency bell installed in area C 402 on the 3rd basement floor, information on the location of the emergency signal generation can be stored as F3C-402.

For parking locations, two or more electric vehicles may be parked substantially simultaneously within the same parking zone group, as shown in area AR21. In this case, automatic authentication as in Figure 6 is not performed. In other words, in the case of electric vehicle charging, as shown in the AR41 area, if the device ID and charging location information of the electric vehicle charging device can be stored redundantly, it is not possible to determine whether the resident of building 101, room 501 is attempting charging or the resident of building 101, room 101. An action is required to determine whether charging is attempted. Therefore, in a special case where a plurality of electric vehicles are parked and a charging request is made, the parking lot terminal group 200 receives the ID of the charging requester and performs authentication through operation S1302 without performing automatic authentication.

Therefore, even when different electric vehicles approach an electric vehicle charging device and attempt to charge, electric vehicle charging can be performed without charging recognition errors.

FIG. 10 is a flowchart showing an example of the charging process according to FIG. 5.

The charging process shown in FIG. 10 may be performed by the electric vehicle charging device 100 through the charging cable 30 including the in-cable control box 32, but is not limited thereto. First, when providing wired charging to the electric vehicle 20, the electric vehicle charging device 100 can detect that the charging connector 31 is connected to the electric vehicle 20 (S1101). In one embodiment, information about the electric vehicle charging device 100 may be transmitted to the electric vehicle 20 when necessary to make charging the electric vehicle easier (S1102). Thereafter, when the electric vehicle charging device 100 detects that the charging connector 31 is connected, it generates a charging attempt signal and transmits it to the parking lot terminal group 200. When the charging attempt signal is received, the parking lot terminal group 200 automatically authenticates whether the electric vehicle attempting to charge is the resident's vehicle based on the parking guidance information and parking location confirmation information. When authentication is successful with the resident's vehicle, the parking lot terminal group 200 transmits a charging approval message to the electric vehicle charging device 100. Accordingly, the electric vehicle charging device 100 receives the charging approval message and starts charging (S1103). The electric vehicle charging device 100 accumulates and measures the amount of power charged after the start of charging, and when it recognizes a charging termination operation detected from the user or the electric vehicle 20 (S1104), it derives charging information based on the accumulated measured amount of power (S1104) S1105). The derived charging information can be transmitted to the electric vehicle using short-distance wireless communication (S1106).
