Description

Technology Field

[0001] The present invention relates to a vehicle charging system and a control method thereof, and more specifically, to a vehicle charging system and a control method thereof capable of selectively charging vehicles parked in multiple parking spaces using a single charging device. Background Technology

[0002] Electrified vehicles, such as electric vehicles (EVs) or plug-in hybrid electric vehicles (PHEVs), can charge their built-in batteries using power supplied from an external charging device.

[0003] These electrified vehicles utilize motors as a power source, which offer faster responsiveness compared to internal combustion engines, resulting in superior driving performance and improved energy efficiency through regenerative braking. However, they require longer charging times than refueling and present challenges regarding the widespread availability of chargers.

[0004] In particular, even in facilities equipped with large parking lots, such as apartment complexes, the number of parking spaces equipped with charging devices is limited. Consequently, the inconvenience of charging can be felt more acutely due to reasons such as fully charged vehicles remaining stationary or internal combustion engine vehicles parking in the same spots. In reality, the primary cause of this inconvenience is the cost, in addition to the spatial constraints, of installing charging devices in every single parking space.

[0005] The matters described above as background technology are intended only to enhance understanding of the background of the present invention and should not be construed as an acknowledgment that they constitute prior art already known to those skilled in the art. The problem to be solved

[0006] Accordingly, the present invention has the technical objective of providing a vehicle charging system and a control method thereof that can selectively charge vehicles parked in multiple parking spaces using a single charging device.

[0007] The technical problems to be solved by the present invention are not limited to those mentioned above, and other technical problems not mentioned will be clearly understood by those skilled in the art to which the present invention belongs from the description below. means of solving the problem

[0008] As a means for solving the above technical problem, a vehicle charging system according to one embodiment of the present invention comprises: a plurality of parking space facilities installed to correspond to parking spaces; a charger that supplies charging power; and a server connected to each of the plurality of parking space facilities so as to be able to communicate with each of the plurality of parking space facilities, wherein each of the plurality of parking space facilities may include: an identification unit that identifies a vehicle located in the corresponding parking space; a power transmission unit having a power transmission means that supplies the charging power to the vehicle; and a controller having a switch that communicates with the server and selectively connects a charging cable between the power transmission unit and the charger.

[0009] For example, the identification unit can identify the vehicle by recognizing the license plate from an image captured through a camera.

[0010] For example, the controller may transmit vehicle detection information, including the result of identifying the vehicle, to the server.

[0011] For example, the server may perform a charging decision for the vehicle based on the vehicle detection information and transmit switch control information corresponding to the result of the charging decision to each of the plurality of parking space facilities.

[0012] For example, when multiple different vehicle detection information is received from different parking space facilities, the server can determine the charging order between vehicles based on entry time information or scheduled exit time.

[0013] For example, the server can transmit the switch control information to each of the plurality of parking space facilities based on the charging order between the vehicles.

[0014] For example, the switch control information may be set so that the switch corresponding to the current vehicle to be charged according to the vehicle-to-vehicle charging order is closed, and the switches of the remaining parking space facilities are opened.

[0015] For example, the server may determine the switch status of each of the plurality of parking space facilities according to the switch control information, and if the switch status is satisfied, transmit charging control information to the charger.

[0016] For example, the charger can start supplying the charging power based on the charging control information.

[0017] Additionally, a vehicle charging system according to another embodiment of the present invention comprises: a plurality of parking space facilities installed to correspond to parking spaces; a main controller installed between a charger that supplies charging power and the plurality of parking space facilities; and a server connected to communicate with the main controller, wherein each of the plurality of parking space facilities includes: an identification unit that identifies a vehicle located in the corresponding parking space; a power transmission unit having a power transmission means that supplies charging power to the vehicle; and a sub-controller that communicates with the main controller, and the main controller may have a switch that selectively connects a charging cable between the power transmission unit of any one of the plurality of parking space facilities and the charger according to the instructions of the server. Effects of the invention

[0018] According to embodiments of the present invention, a charging device and a plurality of parking space facilities can be connected selectively or sequentially through vehicle recognition.

[0019] Therefore, the financial burden of having to install charging devices in every parking space can be reduced.

[0020] The effects obtainable from the present invention are not limited to those mentioned above, and other unmentioned effects will be clearly understood by those skilled in the art from the description below. Brief explanation of the drawing

[0027] Hereinafter, a vehicle charging system and a control method according to various embodiments of the present invention will be described in detail with reference to the attached drawings.

[0028] FIG. 1 is a block diagram showing an example of a vehicle charging system configuration according to one embodiment of the present invention, and FIG. 2 is a conceptual diagram of a parking lot to which a vehicle charging system according to one embodiment is applied.

[0029] Referring to FIG. 1 and FIG. 2 together, a vehicle charging system according to one embodiment may include a server (100), a charger (200), and a plurality of parking space facilities (300-1, 300-2, ... 300-N).

[0030] The server (100) is connected to communicate with the charger (200) and multiple parking space facilities (300-1, 300-2, ... 300-N), thereby enabling the transmission and reception of status information and control information. The server (100) may be provided on a parking lot unit basis, multiple servers (100) may be provided for each section within a single parking lot, or multiple parking lots may be managed by a single server (100). For example, in the case of an apartment complex, one server (100) may be provided for each building, one server (100) may manage the parking lot of the entire complex, or one server (100) may manage multiple apartment complexes.

[0031] The server (100) can manage user information related to charging for each vehicle. For example, the server (100) manages vehicles by registration number (license plate), and the information related to charging may include payment method information, entry time information, expected exit time information, and charging method information (slow / fast, etc.). The payment method information may include credit card information, charging payment agency service account information, etc., but is not necessarily limited to these. For example, the payment method information may additionally include address information so that charging fees can be added to management fees and billed, assuming an apartment or office.

[0032] The charger (200) can receive grid power, convert it into power suitable for charging the battery of a vehicle to be charged, and supply it to the vehicle. For example, the charger (200) may be an EVSE (Electric Vehicle Supply Equipment). Additionally, the charger (200) can start or stop the supply of charging power according to instructions from the server (100).

[0033] Each of the multiple parking space facilities (300-1, 300-2, ... 300-N) may be provided in a parking lot corresponding to an individual parking space and may include a controller (310), an identification unit (320), and a power transmission unit (330).

[0034] The controller (310) may have communication capabilities with the charger (200) and the server (100).

[0035] The identification unit (320) may have a configuration suitable for identifying a vehicle parked in a parking space equipped with the corresponding parking space facility. For example, the identification unit (320) may include a camera to photograph the license plate of a vehicle parked in the parking space and obtain license plate information through image recognition from the captured image. The license plate information may be transmitted to a controller (310), and the controller (310) may then transmit it to a server (100). According to an embodiment, the identification unit (320) may further include information input / output means. The information input / output means may include at least one of a key button, a card recognition device (reader), a tag recognition device, and a display device (or touchscreen). Through the information input / output means, the user may input user information related to charging or register payment methods, etc. Such information input / output means may be particularly useful for easily registering user information for the first time when user information is not previously registered in the server (100).

[0036] The power delivery unit (330) can perform the function of delivering charging power supplied from the charger (200) to a vehicle parked in the corresponding parking space. For example, the power delivery unit (330) may include a charging connector.

[0037] Meanwhile, the controller (310) may include a switch (311) to allow the charger (200) and the power delivery unit (330) to be selectively connected according to the instructions of the server (100). At this time, the switch (311) may selectively connect or disconnect each line corresponding to the charging method supported by the charger (200). For example, if the charger (200) supports a combo method, the connector includes a total of 7 pins: 5 pins for slow charging (① AC 220V / neutral ② AC 220V ③ Ground ④ CP signal line ⑤ PD signal line) and 2 pins for fast charging (⑥ DC(+) ⑦ DC(-)). Accordingly, the charger (200) and the power delivery unit (330) are connected by a charging cable having a total of 7 lines, and the switch (311) may be configured to simultaneously connect or disconnect each of the 7 lines of the cable. Accordingly, by closing the switch of only one of the multiple parking space facilities (300-1, 300-2, ... 300-N) and opening the switch of the remaining parking space facilities, the charger (200) can be connected one-to-one with the power delivery unit corresponding to the parking space facility with the closed switch. That is, from the perspective of the charger (200), it is equivalent to having a single charging connector. Therefore, there is no need for the structure of the charger (200) to become complex or for the control of the charging process performed by the charger (200) to change, and since a single charger (200) can selectively charge vehicles parked in multiple parking spaces through the control of the switch (311), there is no need to provide a charger (200) for each parking space.

[0038] Below, the process of vehicle charging is described based on the configuration of the vehicle charging system described with reference to FIGS. 1 and FIGS. 2.

[0039] FIG. 3 shows an example of a charging process through a vehicle charging system according to one embodiment.

[0040] Referring to FIG. 3, user information related to charging, such as a user vehicle, can first be registered with the server (100) through the user terminal (10) (S301). As described above, user information related to charging may include vehicle identification information (license plate), payment method information, entry time information, expected exit time information, charging method information (slow / fast, etc.). Additionally, any type of terminal such as a smartphone, tablet, laptop, or PC can be used as long as it can execute a webpage or application that provides a user interface for registering user information with the server (100). Furthermore, the user terminal (10) may be a public kiosk in the case of a public parking lot, etc., or a PC in the management office in the case of a multi-unit dwelling such as an apartment.

[0041] Subsequently, when a vehicle wishing to charge enters the parking lot and parks on a parking space equipped with a parking space facility (assumed to be 300-1 here), the identification unit (320) of the parking space facility identifies the license plate of the parked vehicle, and the controller (310) can transmit this as vehicle detection information to the server (100) (S302). Here, it is assumed that the driver of the vehicle takes measures to supply charging power to the vehicle through the power delivery unit (330) after parking (e.g., connecting a charging connector).

[0042] The server (100) can query user information related to charging based on license plate information included in vehicle detection information and make a judgment regarding charging based on the query result (S303). The judgment regarding charging may include judgments on whether charging is possible, the amount of charging, the time of charging start, etc. For example, the server (100) can determine that charging is possible if there is a user information item related to charging corresponding to the license plate information and a valid payment method is registered. In addition, if the server (100) has a scheduled exit time in the user information item related to charging, it can adjust the charging order among vehicles that are recognized as already parked so that charging can be performed before the scheduled exit time. If there is no information on the scheduled exit time, the server (100) can determine the charging order among vehicles in the order of parking (entry).

[0043] Although not shown, if the server (100) determines that charging-related user information regarding the license plate included in the vehicle detection information has not been registered, it may transmit registration request information to the controller (310). In this case, the controller (310) may receive charging-related user information through an information input / output means (not shown) and transmit it back to the server (100). Once user information is registered to the server (100) through the process described above, it may be possible to determine charging using the user information at any parking lot nationwide that can access the server (100).

[0044] The server (100) can transmit switch control information to the controller (310) of each parking space facility according to the result of the charging judgment (S304). For example, when charging is initiated for a vehicle parked in parking space 1, the server (100) can instruct the controller (310) of the parking space facility (300-1) corresponding to parking space 1 to close the switch (311), and can instruct the controller (310) of the remaining parking space facilities to open the switch (311). In other words, the switch control information can be set so that the switch (311) of the parking space facility (300-1) where the vehicle currently to be charged is parked according to the charging order between vehicles is closed, and the switch of the remaining parking space facilities is opened. Through this, the server (100) can enable the power transmission unit (330) of the parking space facility (300-1) where the vehicle to be charged is parked to be charged currently is connected to the charger (200).

[0045] When the switch (311) is controlled according to the switch control information (S305), the controller (310) can report the switch control result to the server (100) (S306).

[0046] When the switch status for each parking space facility is checked, the server (100) can transmit charging control information to the charger (200) (S307). For example, the charging control information may include information instructing the initiation of a charging procedure, the charging method of the vehicle to be charged, the target charging amount, etc., but this is exemplary and is not necessarily limited thereto.

[0047] Afterward, the charger (200) can perform charging according to a predefined procedure for each charging method (e.g., detecting CP voltage change when using CP) (S308).

[0048] The result of the charging operation (e.g., charging completed or charging failed) can be transmitted from the charger (200) to the server (100) (S309). If the charger (200) also has a payment function, payment method information can be obtained from the charger (200) during the process of receiving charging control information (S307); otherwise, the server (100) can perform payment based on the charging result. Additionally, the server (100) may transmit the charging result to a pre-registered user terminal (10) (S310).

[0049] The aforementioned steps S302 to S309 are performed sequentially according to the parking spaces, thereby enabling vehicles parked in multiple parking spaces to be charged using a single charger (200). Accordingly, the burden of installation costs for the charger (200) can be significantly reduced.

[0050] Although FIG. 3 is described based on a single parking space facility (300-1), it is obvious that the server (100) can perform switch control again so that a vehicle parked in another parking space can be charged once the charging of the vehicle parked in the corresponding parking space is completed.

[0051] In the above-described embodiment, a controller (310) including a switch (311) is provided for each parking space facility, but according to another embodiment, a main controller including a switch may be provided between the charger and the plurality of parking space facilities. This will be explained with reference to FIGS. 4 to 6.

[0052] FIG. 4 is a block diagram showing an example of a vehicle charging system configuration according to another embodiment of the present invention, and FIG. 5 is a conceptual diagram of a parking lot to which a vehicle charging system according to another embodiment is applied.

[0053] Referring to FIG. 4 and FIG. 5 together, a vehicle charging system according to another embodiment may include a server (100), a charger (200), a main controller (400), and a plurality of parking space facilities (500-1, 500-2, ... 500-N).

[0054] The server (100) is connected to the main controller (400) for communication, thereby enabling the transmission and reception of status information and control information. The server (100) may be provided on a parking lot basis, multiple servers (100) may be provided for each section within a single parking lot, or a single server (100) may manage multiple parking lots. For example, in the case of an apartment complex, a single server (100) may be provided for each building, a single server (100) may manage the parking lot of the entire complex, or a single server (100) may manage multiple apartment complexes.

[0055] The server (100) can manage user information related to charging for each vehicle. For example, the server (100) manages vehicles by registration number (license plate), and the information related to charging may include payment method information, entry time information, expected exit time information, and charging method information (slow / fast, etc.). The payment method information may include credit card information, charging payment agency service account information, etc., but is not necessarily limited to these. For example, the payment method information may additionally include address information so that charging fees can be added to management fees and billed, assuming an apartment or office.

[0056] The charger (200) can receive grid power, convert it into power suitable for charging the battery of a vehicle to be charged, and supply it to the vehicle. For example, the charger (200) may be an EVSE (Electric Vehicle Supply Equipment). Additionally, the charger (200) can start or stop supplying charging power according to instructions from the main controller (400).

[0057] The main controller (400) is connected to communicate with the server (100), the charger (200), and each of the multiple parking space facilities' sub-controllers (510), and may include a switch (410). The function of the switch (410) will be described later.

[0058] Each of the multiple parking space facilities (500-1, 500-2, ... 500-N) may be provided in a parking lot corresponding to an individual parking space and may include a sub-controller (510), an identification unit (520), and a power transmission unit (530).

[0059] The sub-controller (510) can have a communication function with the main controller (400).

[0060] The identification unit (520) may have a configuration suitable for identifying a vehicle parked in a parking space equipped with the corresponding parking space facility. For example, the identification unit (520) may include a camera to photograph the license plate of a vehicle parked in the parking space and obtain license plate information through image recognition from the captured image. The license plate information may be transmitted to a sub-controller (510), and the sub-controller (510) may then transmit it to the main controller (400). According to an embodiment, the identification unit (520) may further include information input / output means. The information input / output means may include at least one of a key button, a card recognition device (reader), a tag recognition device, and a display device (or touchscreen). Through the information input / output means, the user may input user information related to charging or register payment methods, etc. Such information input / output means may be particularly useful for easily registering user information for the first time when user information is not previously registered in the server (100).

[0061] The power delivery unit (530) can perform the function of delivering charging power supplied from the charger (200) to a vehicle parked in the corresponding parking space. For example, the power delivery unit (530) may include a charging connector.

[0062] Meanwhile, the main controller (400) includes a switch (410) to allow the charger (200) and the power delivery unit (530) of a specific parking space facility to be selectively connected according to the instructions of the server (100). At this time, the switch (410) can connect each line corresponding to the charging method supported by the charger (200) to the power delivery unit (530) of any one of the multiple parking space facilities. For example, if the charger (200) supports a combo method, the connector includes a total of 7 pins: 5 pins for slow charging (① AC 220V / neutral ② AC 220V ③ ground ④ CP signal line ⑤ PD signal line) and 2 pins for fast charging (⑥ DC(+) ⑦ DC(-)). Accordingly, the charger (200) and the power delivery unit (530) are connected by a total of 7 lines, and the switch (410) can be configured to simultaneously connect or disconnect each of the 7 lines to the line leading to the power delivery unit (530) of a specific parking space facility. Therefore, in the aforementioned embodiment, the switch (311) had to be individually controlled for each parking space facility, but in another embodiment, a one-to-one connection between the charger (200) and the power delivery unit (530) of a specific parking space facility is possible by controlling only the switch (410) of the main controller (400). In other words, in the structure of FIG. 1, the charging cable is branched between the charger (200) and each parking space facility, but in the structure of FIG. 4, the charger (200) and the main controller (400) are connected by a single charging cable, and the charging cable can be seen as being branched within the switch (410) of the main controller (400). Accordingly, the switch (311) of FIG. 1 has only a one-to-one connection per line and is controlled to an open or closed state, whereas the switch (410) of FIG. 4 has a one-to-many connection for each parking space facility per line and can have a close state and an open state corresponding to each parking space facility.

[0063] As a result, in this embodiment, from the perspective of the charger (200), it is equivalent to having a single charging connector. Therefore, there is no need for the structure of the charger (200) to become complex or for the control of the charging process performed by the charger (200) to change, and since a single charger (200) can selectively charge vehicles parked in multiple parking spaces through the control of the switch (410), there is no need to provide a charger (200) for each parking space.

[0064] Below, the process of vehicle charging is described based on the configuration of the vehicle charging system described with reference to FIGS. 4 and FIGS. 5.

[0065] FIG. 6 shows an example of a charging process through a vehicle charging system according to another embodiment.

[0066] Referring to FIG. 6, user information related to charging, such as a user vehicle, can first be registered with the server (100) through the user terminal (10) (S601). Since this step is similar to step S301 of FIG. 3, a redundant description will be omitted.

[0067] Subsequently, when a vehicle wishing to charge enters the parking lot and parks on a parking space equipped with a parking space facility (assumed to be 500-1 here), the identification unit (520) of the parking space facility identifies the license plate of the parked vehicle, and the sub-controller (510) can transmit this as vehicle detection information to the main controller (400) (S602). Here, it is assumed that the driver of the vehicle takes measures to supply charging power to the vehicle through the power delivery unit (530) after parking (e.g., connecting a charging connector).

[0068] The main controller (400) transmits the vehicle detection information back to the server (100) (S603), and the server (100) can query user information related to charging based on the license plate information included in the vehicle detection information and perform a judgment on charging based on the query result (S604). The charging judgment process (S604) is similar to step S303 of FIG. 3, so redundant descriptions will be omitted. The case where the server (100) determines that user information related to charging for the license plate included in the vehicle detection information is not registered is similar.

[0069] The server (100) can transmit charging control information to the main controller (400) based on the result of the charging judgment (S605). For example, the charging control information may include information regarding switch control information, information regarding the parking space (or parking space facility) where the vehicle to be charged is parked, the charging method of the vehicle to be charged, the target charging amount, etc., but this is exemplary and is not necessarily limited thereto.

[0070] The main controller (400) can control the switch (410) based on charging control information received from the server (100) (S606). For example, the main controller (400) can control the switch (410) so that the charger (200) is connected to the power delivery unit (530) of the parking space facility (500-1) corresponding to the parking space where the vehicle to be charged is parked.

[0071] When the control of the switch (410) is completed, the main controller (400) can transmit charging control information to the charger (200) (S607). Here, the charging control information may include information instructing the initiation of a charging procedure, the charging method of the vehicle to be charged, the target charging amount, etc., but this is exemplary and is not necessarily limited thereto.

[0072] Afterward, the charger (200) can perform charging according to a predefined procedure for each charging method (e.g., detecting CP voltage change when using CP) (S608).

[0073] The result of the charging operation (e.g., charging completed or charging failed) can be transmitted from the charger (200) to the main controller (400) (S609). The main controller (400) can then transmit the charging result to the server (100) (S610).

[0074] If the charger (200) also has a payment function, payment method information may be obtained from the charger (200) during the process of receiving charging control information (S607); otherwise, the server (100) may perform payment based on the charging result. Additionally, the server (100) may transmit the charging result to a pre-registered user terminal (10) (S611).

[0075] Each of the aforementioned steps is performed sequentially according to the parking space, thereby enabling vehicles parked in multiple parking spaces to be charged using a single charger (200). Accordingly, the burden of installation costs for the charger (200) can be significantly reduced.

[0076] Although Fig. 6 is also described based on one parking space facility (500-1), it is obvious that the server (100) can transmit charging control information to the main controller (400) so that when charging for a vehicle parked in the corresponding parking space is completed, a vehicle parked in another parking space can be charged.

[0077] FIG. 7 shows an example of a possible parking lot to which the embodiments are applied.

[0078] The power delivery unit (330) shown in FIG. 2 and the power delivery unit (530) shown in FIG. 5 are shown as charging connectors, but with reference to FIG. 7, the power delivery unit (330') of each parking space facility (300-1') may be implemented in the form of a wireless charging pad.

[0079] Meanwhile, the present invention described above can be implemented as computer-readable code on a medium on which a program is recorded. A computer-readable medium includes all types of recording devices in which data that can be read by a computer system is stored. Examples of computer-readable media include HDD (Hard Disk Drive), SSD (Solid State Disk), SSD (Silicon Disk Drive), ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage device, etc. Accordingly, the above detailed description should not be interpreted restrictively in all respects and should be considered exemplary.
