Description

Rail Mobile Electric Vehicle Charging System

The present invention relates to an electric vehicle charging system, and specifically to a rail-mobile electric vehicle charging system that can charge multiple electric vehicles through an electric vehicle charger that can move along rails.

The content described below simply provides background information related to this embodiment and does not constitute prior art.

Recently, the electric vehicle market using batteries is growing rapidly with the purpose of drastically reducing fossil energy due to climate change caused by pollution caused by fossil fuels.

Accordingly, the electric vehicle charger market is also growing rapidly, and the installation of electric vehicle chargers in building parking lots is also spreading. However, currently, in order to install an electric vehicle charger in an existing communal parking lot, it is difficult to obtain the consent of residents who mostly use regular vehicles. Although it is mandatory for new apartments, there are also limitations due to the limited space and number of chargers. You must charge your electric vehicle in a dedicated space for electric vehicle charging and remove the vehicle quickly when charging is complete. Otherwise, it can be said that the stress on users is very great because they have to pay a fine.

Recently, in order to overcome the limitations of installing conventional electric vehicle chargers, a mobile electric vehicle charging system has been developed that allows charging parked electric vehicles by installing a movable charger on the ceiling of a parking lot. The mobile electric vehicle charger is equipped with multiple chargers and is configured to move forward or backward along the rail, so it has the advantage of being able to move to the place where the electric car is parked and charge it more efficiently, so there is no need for a dedicated charging space (parking surface).

However, in the case of such a mobile electric vehicle charging system, a plurality of mobile electric vehicle chargers are implemented so that they can move along one guide rail, so when one charger is charging a specific electric vehicle, other chargers may pass beyond the charging charger. As the number of portable chargers increases, there are bound to be many restrictions on their use. Additionally, since other people cannot unplug the rechargeable gun once charging is complete, the inconvenience of having to immediately come and unplug the recharged gun remains. In addition, all mobile chargers require moving parts, which increases the cost of the charger.

In general, in the case of a conventional mobile electric vehicle charging system, a plurality of mobile electric vehicle chargers are implemented so that they can move along one guide rail, so when one electric vehicle charger is charging, another electric vehicle charger cannot move over, which limits its use. Additionally, all mobile chargers have the disadvantage of being expensive because they require a driving part. Additionally, there is the inconvenience of having to remove the electric vehicle when charging is complete.

The present invention was devised to solve the above problems, and is provided with a plurality of electric vehicle chargers that can move along a rail, but is implemented so that other chargers can pass over even when a specific charger is charging, and the electric vehicle charger is provided through a separate means of transportation. By adopting a method of moving the charger, the moving part is removed from the mobile electric vehicle charger, and an environment is created so that others can unplug the charging gun even after charging is completed. This is a rail mobile electric vehicle charging system that does not require the user to immediately remove the car even after charging is complete. The purpose is to provide.

In order to achieve the above object, the present invention, in a rail mobile electric vehicle charging system,

AC/DC converter that receives three-phase AC power and creates DC power;

An electric vehicle charger including an electric vehicle charging module that receives the DC power and supplies the current necessary for charging an electric vehicle, an input terminal provided at the input terminal of the electric vehicle charging module, and a reel-type charging cable connected to the output terminal of the electric vehicle charging module and a charging gun. ;

A plurality of predetermined charging spots where a plurality of the electric vehicle chargers are mounted;

A power terminal provided at each charging spot and connected to the input terminal in a contact manner to supply the DC power;

Connecting means for connecting the AC/DC converter and the power terminal or connecting the power terminal and another power terminal adjacent to the power terminal;

A moving means that moves along a predetermined rail, moves the electric vehicle charger to one of the charging spots, and mounts it so that the input terminal of the electric vehicle charger and the power terminal are connected to each other;

a system controller that controls the entire system;

It is characterized by comprising a remote server device that receives a charging request through a user terminal, issues a charging command to the system controller, and monitors the charging status through the system controller.

In addition, in the present invention, the rails are arranged at a predetermined distance from the charging spot to prevent physical interference between the electric vehicle charger already mounted on the charging spot and the moving means for moving other electric vehicle chargers. .

In addition, in the present invention, the electric vehicle charger includes a camera to monitor the electric vehicle through video during charging or after charging is completed, thereby making it possible to determine who is responsible for damage to the vehicle, etc., thereby creating an environment where others can unplug the charging gun. By providing this, it has the advantage that the electric vehicle charger user does not have to remove the vehicle immediately after charging is completed.

In addition, in the present invention, the electric vehicle charger and the transportation means include a thermal imaging camera to monitor fire in the electric vehicle while parked or charging, and when a fire occurs, a fire alarm is sent, and the transportation means extinguishes a fire extinguisher at the location of the electric vehicle where the fire occurred. You can add a function to extinguish a fire by moving it to and spraying fire extinguishing liquid.

In the case of the rail mobile electric vehicle charging system according to the present invention, the electric vehicle charger moving along the rail can be moved to an arbitrary location for charging, so there is no need to designate a parking lot exclusively for electric vehicle charging, and electric vehicles and regular vehicles can be parked without distinction. In this case, there is no problem at all with charging an electric vehicle, and there is no need to move the electric vehicle to another space even after charging is completed, which has the effect of maximizing the convenience of charging.

In addition, a thermal imaging camera is used to monitor electric vehicle fires that may occur while parking or charging, and when a fire occurs or signs of a fire are visible, a fire alarm is sent and a fire extinguisher is moved directly to a means of transportation to extinguish a fire in an electric vehicle. It can also be suppressed.

A preferred embodiment of the present invention will be described in detail with the accompanying drawings as follows. The detailed description below is merely illustrative and merely illustrates preferred embodiments of the present invention.

Figure 1 is a configuration diagram of a conventional mobile electric vehicle charging system.

Referring to Figure 1, in the conventional mobile electric vehicle charging system, a rail 100 is installed along the ceiling of the parking space, and the charger 110 moves along the rail 100 to charge the electric vehicle 120 parked in a specific parking space. ) is configured to be able to charge.

The rail 100 is mainly installed on the ceiling of the parking space, and the charger 110 moves along the rail using a traveling drive device for driving.

The charger 110 moves along the rail 100, stops at a parking surface where charging is desired, and performs the function of supplying electricity to the parked electric vehicle 120. A plurality of chargers 110 may be installed depending on the size of the parking space, and each of the plurality of chargers 110 is implemented to be movable along one rail 100.

The charger 110 may be configured to include a charging member consisting of a reel-type charging cable 111 to which a charging gun 112 is attached, and the user of the electric vehicle pulls the reel-type charging cable 111 to attach the charging gun to the electric vehicle. Charging of the electric vehicle 120 can be performed by moving it close to the inlet position and combining it with the inlet of the electric vehicle.

Such a conventional mobile electric vehicle charging system has an advantage in that it can solve the problem of space limitations compared to the case where the electric vehicle charger is implemented as a fixed type. In fact, referring to FIG. 1, the mobile electric vehicle charging system visits the parking surface where the electric vehicle is parked and charges it, so there is no need for a dedicated space for charging the electric vehicle, and therefore, electric vehicles and regular vehicles can be parked without distinction.

However, the conventional mobile electric vehicle charging system has no problem when operating one electric vehicle charger on one rail, but when operating multiple electric vehicle chargers on one rail, when one electric vehicle charger is charging, the other mobile electric vehicle charges. Since the charger cannot go beyond the electric vehicle charger that is already charging, it has the disadvantage of not being able to efficiently operate multiple mobile chargers.

In addition, since an electric vehicle that is fully charged must be removed from its charging gun to be able to charge another electric vehicle, the charger user has the disadvantage of existing stationary chargers that they must receive a call and remove the charging gun from their electric vehicle upon completion of charging.

In order to overcome the limitations of the conventional mobile electric vehicle charging system as described above, in the present invention, there is no need to designate a parking lot exclusively for charging electric vehicles, and there is no problem in charging electric vehicles even when parking electric vehicles and regular vehicles without distinction. We propose a rail mobile electric vehicle charging system with a new structure that maximizes the convenience of charging by eliminating the need to move the electric vehicle to another space even after completion.

Figure 2 is a configuration diagram of a rail mobile electric vehicle charging system according to the present invention. The rail mobile electric vehicle charging system according to the present invention includes a plurality of electric vehicle chargers 200, a plurality of charging spots 210, a power terminal 220 provided at each charging spot, an AC/DC converter 230, and an AC/DC converter. (230) It is configured to include a connecting means 232 that connects the output terminal and a power terminal or another power terminal adjacent to the power terminal, a moving means 250, a system controller 260, and a remote server device 270.

The electric vehicle charger 200 is an electric vehicle charger module that receives DC power from the AC/DC converter 230 and supplies the current required for charging an electric vehicle, an input terminal provided at the input terminal of the electric vehicle charging module, and an input terminal connected to the output terminal of the electric vehicle charging module. It is comprised of a reel-type charging cable (111) and a charging gun (112).

The electric vehicle charging module forms a charger housing that accommodates and moves the reel-type charging cable 111, and receives DC input power through an input terminal to provide power for charging.

The reel-type charging cable 111 is composed of a charging cable wound on a winding reel. At this time, the winding reel is configured to be rotatable on a reel bracket and is driven to rotate in both directions by a driving means, through which the charging cable is wound. It is constructed so that it can be opened or released.

The reel-type charging cable 111 may be implemented in a manual manner, in which the reel-type charging cable is manually unwound and lowered by the user, or in an automatic manner, in which the reel-type charging cable is automatically unwound and lowered by a separately provided driving unit.

In the case of the manual method, when the electric car charger is mounted on the power terminal and the input terminal of the electric car charger is connected to each other, the user of the electric car pulls the reel-type charging cable (111) wound on the electric car charger and connects the charging gun to the electric car. Charging of the electric vehicle 120 can be performed by moving it close to the inlet position and combining it with the inlet of the electric vehicle.

In the case of the automatic method, the reel-type charging cable 111 may be implemented in a way that it is automatically released and lowered by a separately provided driving unit. In this case, the reel-type charging cable automatically lowers to the vehicle height of the electric vehicle and can be operated manually by the user thereafter. When charging start information is input from the user terminal, the reel-type charging cable automatically lowers and charging begins. After completion, it can be implemented to automatically go up when the charging gun is pulled out.

In the present invention, unlike the conventional mobile charger 110 that moves directly along a rail, the electric vehicle charger 200 is moved by a moving means 250 and moved to the parking position of the electric vehicle 120 to be charged. More specifically, the electric vehicle charger 200 is moved to a predetermined charging spot by the moving means 250, and then is placed on the charging spot and the input terminal is connected to the power terminal provided in the charging spot to receive power. It performs a charging function.

The electric vehicle charger 200 may include an initial charging circuit (not shown) at the input terminal to block spark generation when mounted on the contact terminal. At this time, the initial charging circuit may be composed of a series switch at the input terminal of the electric vehicle charger and an auxiliary switch connected in series with the initial charging resistor.

A plurality of electric vehicle chargers 200 may be provided, and depending on the embodiment, the plurality of electric vehicle chargers may have different charging capacities for each individual or group. For example, a plurality of electric vehicle chargers may be provided with different capacities in 2 to 5 levels so that the charging user can select one. Meanwhile, in the present invention, the capacity applied to a plurality of electric vehicle chargers is not limited to a specific capacity.

Meanwhile, in the case of the present invention, in order to enable charging of electric vehicles through a plurality of electric vehicle chargers 200 more efficiently, the sum of the capacities of the plurality of electric vehicle chargers is implemented to have a larger value than the capacity of the AC/DC converter 230. It can be. For example, it is desirable that the total capacity of a plurality of electric vehicle chargers is implemented to have a capacity of about 1.3 to 2 times that of the AC/DC converter 230, but is not necessarily limited to this.

In the present invention, the rail mobile electric vehicle charging system charges with spare power within a range that does not exceed the customer's contracted power, and charges according to the user's charging priority. For example, for the rail mobile electric vehicle charging system, if the contracted power for the apartment where the rail mobile electric vehicle charging system is currently installed is 1,000 kW, and the current power usage for the apartment is 850 kW, the limit for all electric vehicle chargers is used for the spare power of 150 kW. It can be set as power and divided and used according to preset priorities. This can be flexibly changed in response to changes in spare power.

The rail mobile electric vehicle charging system according to the present invention may be configured by additionally including an energy storage device (ESS, 300) at the output terminal of the AC/DC converter (230).

The energy storage device 300 charges the power late at night or when there is a lot of spare power, and then discharges the energy when there is a lot of charging demand to cover the charging demand.

The charging spot 210 is configured to accommodate a plurality of electric vehicle chargers and includes a power terminal 220 that is contact-connected to the input terminal of the electric vehicle charger.

A plurality of charging spots 210 may be placed in a predetermined location, where the determined location may be a location corresponding to a parking space where an electric vehicle is parked for charging. More preferably, the charging spot 210 may be provided in the upper space of the vehicle between the parking surface and the parking surface. This has the effect of enabling charging without problems such as cable twisting, regardless of whether the inlet of the electric vehicle to be charged is located on the left or right side relative to the reel-type charging cable of the electric vehicle charger.

The charging spot 210 may preferably be placed on the ceiling. For example, the charging spot 210 according to the present invention may be implemented as a structure arranged on the ceiling through a fixing fixture 240 fixed to the ceiling by an electric bolt. This fixed fixture 240 is preferably an H-beam, L-angle, or monorail-type fixture, but is not necessarily limited thereto.

Meanwhile, in another embodiment, the charging spot 210 may be placed on the rear wall or floor of the parking surface, which will be described later in the process of explaining various embodiments of the rail mobile electric vehicle charging system.

In the case of the present invention, the connection means 232 along the fixing fixture 240 is connected to the power terminal 220 provided in the charging spot 210, and the terminal block can be coupled to facilitate connection. For example, the two connecting means 232 are combined along the fixing fixture 240 and connected to the power terminal on the terminal block, and then come out of the terminal block and connected to the power terminal on the next terminal block along the fixing fixture. At this time, the power terminal 220 is preferably arranged vertically to facilitate connection with the input terminal of the electric vehicle charger, but this is not necessarily limited, and may be arranged horizontally depending on the site situation.

In the present invention, the fixing structure of the charging spot 210 is not limited to a specific structure.

The AC/DC converter 230 receives three-phase AC power and produces DC output, which is provided to a plurality of power terminals 220. To this end, in the case of the present invention, a connection means 232 may be included to electrically connect the output of the AC/DC converter 230 and the power terminal or to electrically connect the power terminal to another power terminal adjacent to the power terminal.

In the present invention, the connection means 232 is preferably composed of a power cable, but is not necessarily limited thereto.

The AC/DC converter 230 can be implemented to enable two-way power conversion. Additionally, the AC/DC converter 230 can be connected to the central point of multiple charging spots to minimize conduction loss when multiple charging spots are connected to each other.

Meanwhile, the rail mobile electric vehicle charging system according to the present invention can increase charging spots and electric vehicle chargers as the number of electric vehicles increases. For example, it is desirable to have at least 50 charging spots 210 in order to reduce the cost burden of installing the rail and moving means 250, but it is not necessarily limited to this.

At this time, if the capacity of the AC/DC converter 230 is insufficient as the number of electric vehicle chargers increases, a separate AC/DC converter 230 is added and its output is connected to one of the power terminals, but the existing AC converter is connected through communication. By exchanging information with the /DC converter 230, the load can be balanced, and the rail mobile electric vehicle charging system can be expanded and installed. The AC/DC converter 230 can communicate with other devices through wired or wireless communication.

The moving means 250 moves along a designated rail 242 and performs the function of moving the electric vehicle charger. The moving means 250 is formed to move back and forth by rotation of a roller fastened to the rail 242. The rail 242 may be configured as a monorail or dual rail.

The moving means 250 can move and place one electric vehicle charger to a specific charging spot according to a command given to the system controller 260 from the remote server device 270.

The means of transportation 250 includes an energy storage device (not shown) and may be driven using energy stored in the energy storage device. The mobile means 250 can be charged by moving to a designated location during rest periods when the mobile means 250 is not driven or when the energy storage device is discharged below a certain level. At this time, a charging means for charging the energy storage device through a contact or non-contact method may be provided at a designated location.

In the present invention, preferably, the rail 242 can be arranged so that no physical interference occurs between the electric vehicle charger already mounted on the charging spot 210 and the moving means for moving other electric vehicle chargers.

For this reason, in the case of the present invention, the moving means 250 can move one electric vehicle charger to another charging spot even if another electric vehicle charger is already connected and fixed on one charging spot, so that all There is an advantage in that the mobile electric vehicle charger can be moved to a desired location and charged freely. This means that there is no need to designate a parking lot exclusively for charging electric vehicles, and there are no problems with charging electric vehicles even if electric vehicles and regular engine vehicles are parked without distinction.

The charging spot 210 may be assigned a unique spot number, and the remote server device 270 recognizes the required charging spot 210 through the user terminal and issues a command to the system controller 260 to charge the electric vehicle. You can move and place the device to the corresponding charging spot and proceed with charging based on the charging information obtained through the user terminal. At this time, in order to accurately recognize the charging spot with the user terminal, a display means (not shown) may be included on the parking surface, vehicle, wall, or charging spot itself. The display means may be a barcode, QR-code, or the like.

Hereinafter, with reference to FIGS. 3 and 4 , the process in which the mobile means 250 according to the present invention mounts the electric vehicle charger at a predetermined charging spot and connects the power terminal and the input terminal will be described.

First, referring to (a) of FIG. 3, the process of pulling out and separating the electric vehicle charger that is being mounted by the moving means 250 is explained.

The moving means 250 may be equipped with a robot arm (ARM, 400) that mounts and detaches the electric vehicle charger. Preferably, the robot arm 400 may be implemented to be able to move back and forth in the direction of placement of the charging spot in order to mount and separate the electric vehicle charger on the charging spot. In an embodiment, the robot arm may be implemented to be able to move up and down.

Additionally, the moving means 250 may be provided with a housing (not shown) to support the electric vehicle charger 200 to prevent the electric vehicle charger 200 from falling during movement.

Referring to (b) of FIG. 3, the moving means 250 shows the process of mounting an electric vehicle charger at a predetermined charging spot. Mount the electric vehicle charger on the charging spot so that the power terminal and the input terminal of the electric vehicle charger are electrically connected to each other. For example, the moving means 250 pushes the electric vehicle charger to the placement position of the power terminal through a robot arm so that the electric vehicle charger can be connected to the power terminal.

Meanwhile, in the case of the present invention, the charging spot 210 allows the electric vehicle charger to be physically mounted on the charging spot, and a guide means 410 may be provided to guide the mounting path for this. The guide means 410 may preferably be provided on a terminal block provided corresponding to the charging spot or on a fixing fixture to which the terminal block is coupled. In response to this, a mounting means 420 may also be provided on the electric vehicle charger.

For example, the guide means 410 may be implemented at a position corresponding to the arrangement position of the charging spot within the fixed fixture, and may be implemented in a form that protrudes on both sides in the entry direction of the electric vehicle charger. Correspondingly, the mounting means 420 may be implemented in a form that protrudes perpendicular to the guide means 410 on both sides of the electric vehicle charger 200. According to the structure of the guide means 410 and the mounting means 420, in the case of the present invention, when the electric vehicle charger 200 is pushed toward the charging spot 210 by the robot arm of the moving means 250, the electric vehicle charger is mounted. After the means 420 is placed on the guide means 410, the electric vehicle charger can be mounted on the charging spot by being pushed toward the charging spot along the guide means 410. Meanwhile, a wheel 460 may be provided on the electric vehicle charger to assist the electric vehicle charger to be smoothly pushed in along the guide means 410.

Additionally, fixing means 430 may be provided on the charging spot to secure the electric vehicle charger mounted on the charging spot. Like the guide means 410, the fixing means 430 is implemented in a form that protrudes on both sides in the entry direction of the electric vehicle charger, and is implemented in a structure that surrounds the mounted electric vehicle charger when the electric vehicle charger is mounted on the charging spot. there is. More preferably, the fixing means 430 may be made of an elastic member at a portion where the electric vehicle charger comes into contact with it. For example, when the electric vehicle charger comes into contact with the fixing means 430, the fixing means 430 opens by elasticity and shrinks again to secure the electric car charger by surrounding the electric car charger. This has the additional effect of ensuring that the connection between the power terminal on the charging spot and the input terminal of the electric vehicle charger is firmly maintained. Likewise, the fixing means 430 may also be implemented on a terminal block provided corresponding to the charging spot or on a fixing fixture to which the terminal block is coupled.

Meanwhile, according to this mounting structure of the power terminal and the electric vehicle charger, the moving means 250 is a disassembly means for dismantling the fixing means 430 fastened to the electric vehicle charger first when disconnecting the electric vehicle charger mounted on the charging spot. It may include (440). For example, like the robot arm, the disassembly means 440 can be implemented to be able to move back and forth in the direction of placement of the charging spot, and the end is formed to be inclined to correspond to the end of the fixation means 430, so that it takes precedence when disconnecting the electric vehicle charger. The fixing means 430 is opened in contact with the fixing means 430 so that the fixing means 430 can be dismantled.

In addition, the moving means 250 may include a latch means 450 in the robot arm 400 that assists the robot arm to more efficiently pull and separate the electric vehicle charger when separating the electric vehicle charger mounted on the charging spot. there is. For example, the latch means 450 may preferably be in the shape of a pin, and may be implemented to protrude and fasten to the electric vehicle charger from the side of the robot arm 400. In response to this, a latch hole may also be formed on the electric vehicle charger.

In the present invention, the input terminal of the electric vehicle charger and the power terminal on the charging spot can be electrically connected to each other through a connector contact method. For example, the input terminal and power terminal of an electric vehicle charger may be electrically connected to each other through an elastic contact means or a gravitational force due to the weight of the electric vehicle charger.

Figure 4 is a diagram illustrating a connection method between the input terminal and power terminal of an electric vehicle charger according to the connector contact method.

Figure 4 (a) shows the female connector 500 provided on the input terminal of the electric vehicle charger, Figure 4 (b) shows the male connector 510 provided on the power terminal, and Figure 4 (c) shows the female connector 500 provided on the input terminal of the electric vehicle charger. An example is shown in which the female connector 500 and the male connector 510 of Figure 4 (b) are coupled to each other by the operation of the robot arm of the moving means in Figure 4 (a).

In the present invention, the connection method between the input terminal and the power terminal of the electric vehicle charger is not limited to a specific method.

The system controller 260 performs the function of controlling the entire system. The system controller 260 can exchange information with the AC/DC converter 230, multiple electric vehicle chargers, and the remote server device 270 through wired or wireless communication.

The remote server device 270 receives a charging request through the user terminal, issues a charging command to the system controller 260, and performs the function of monitoring the charging status.

The remote server device 270 recognizes a charging spot requiring charging through the user terminal and issues a command to the system controller 260 to move and place the electric vehicle charger to the charging spot and charge based on the charging information obtained through the user terminal. proceed.

For example, when receiving a request to select a charging spot corresponding to a specific location from a user terminal, the remote server device 270 determines at least one of the presence or absence of a spare electric vehicle charger and the current operating status of an electric vehicle charger connected to the charging spot. Check and select an electric vehicle charger for charging. At this time, the request for selection of a specific charging spot may be a unique spot number previously assigned in relation to the charging spot.

If a request to move to another charging spot is not received for a certain period of time in relation to a fully charged electric vehicle charger, the remote server device 270 may move the electric vehicle charger to a preset storage spot and store it as a spare electric vehicle charger. .

Referring to FIG. 5, the remote server device 270 displays the current charging status of the electric vehicle for which charging has been completed through a separate status display 600. For example, in the case of the present invention, a status display 600 is provided on the electric vehicle charger to display the charging state of the electric vehicle charger, and the provided status display 600 allows the user to check the electric vehicle currently in progress through the electric vehicle charger. You can see that it has been implemented to check the charging status. In the present invention, the display device of the electric vehicle charger changes from red to green when charging of the electric vehicle is completed, but it is not necessarily limited to this.

Meanwhile, in the case of the present invention, as described above, even if the electric vehicle charger is already connected and fixed on one floor charging spot, the means of transportation is implemented so that it can move to another charging spot beyond this, so a plurality of mobile chargers are used. There are no restrictions.

In this regard, referring to FIG. 5, in the present invention, when the remote server device 270 receives a charging request from a specific charging spot, there is no spare electric vehicle charger remaining and charging is completed, but the charging gun is not used in the electric vehicle. When there is an electric vehicle charger plugged in, when the person requesting charging disconnects the charging gun from the electric vehicle, the separated electric vehicle charger is moved to a specific charging spot through a means of transportation to proceed with charging. This means that there is no need to move a fully charged electric vehicle to another space. Therefore, if you park an electric vehicle without needing a separate dedicated charging space and distinguish it from a regular engine vehicle, the electric vehicle charger can search for the electric vehicle and charge it.

To this end, the remote server device 270 may provide information on the existence of a spare electric vehicle charger and the location of a currently fully charged electric vehicle charger to the charging requestor's user terminal. Accordingly, the charging requestor can go to the location of the fully charged electric vehicle charger and separate the charging gun from the electric vehicle parked at that location, thereby allowing the fully charged electric vehicle charger to be moved to a specific charging spot.

In the present invention, when the remote server device 270 receives a charging request through the user terminal, the user agrees to allow others to separate the charging gun from his/her electric vehicle after charging is completed before starting charging. Charging can begin after receiving it through the terminal.

Meanwhile, in the case of the present invention, in order to more smoothly obtain the consent of the charging requester for disconnecting the charging gun through another person, an incentive of a charging fee discount or charging points can be provided to the user who agrees to disconnecting the charging gun. Conversely, users who do not agree to disconnect the charging gun may be subject to a penalty such as forcing them to immediately remove their electric vehicle from the parking space after charging is complete or imposing an additional fee.

In addition, referring to FIGS. 6 and 7, the electric vehicle charger 200 monitors the situation during charging or when the charging gun is disconnected in order to determine who is responsible for an accident that may occur when the charging requester disconnects the charging gun from another person's electric vehicle. It includes a camera 610 capable of monitoring, and the monitoring information can be stored or provided to the user terminal of the electric vehicle through the remote server device 270.

Meanwhile, in addition to a monitoring device for monitoring, a thermal imaging camera 620 for fire detection may be additionally installed on the electric vehicle charger 200. Accordingly, in the case of the present invention, if the temperature of the electric vehicle rises above a certain value during charging, it is considered to be at risk of fire and a charging interruption or fire alarm can be sent to a remote server device through the system controller.
