Referring to FIG. 1 , a fuel cell electric vehicle charging support system according to an embodiment of the present invention includes a charging station 10 for charging a vehicle 1, a terminal device 300, and a charging management server 400, which are It can be connected through a communication network. Here, the vehicle 1 may include a hydrogen fuel cell vehicle and an electric vehicle, but in the embodiment of the present invention, the description will be limited to the hydrogen fuel cell vehicle 1.

The terminal device 300 is a device mounted on the FCEV 1 or a device operated by the driver (owner) of the FCEV 1, and a FCEV charging station management program or application may be installed. Here, the hydrogen electric vehicle 1 corresponds to both a vehicle entering the charging station 10 and charging a fuel cell, or a vehicle waiting to be charged, and the charging station server 100 installed in the charging station 10 and charging While wirelessly communicating with the management server 400, data related to charging of the FCEV 1 may be transmitted to the charging station server 100 and the charging management server 400.

The service information exchanged between the terminal device 300 and the charging management server 400 may include at least one of a charging station location, a charging station direction based on the FCEV 1, a charging station status, and a charging price. The charging station status may include a charging standby situation at the charging station 10, the number of charging devices 15 available at the charging station 10, and the like. The FCEV 1 may receive service information from the charging management server 400 and move to the charging station 10 for charging when seeking to receive a charging service.

In addition, the terminal device 300 may reserve charging of a specific charging station by transmitting charging reservation information including charging station identification information to the charging management server 400 .

In addition, when the FCEV 1 enters the charging station 10 to be charged and is waiting for charging, the terminal device 300 transmits the second vehicle status information to the charging station server 100 in real time, and the expected waiting time for charging , Real-time standby status information including an expected time required for charging may be received from the charging station server 100 . Here, the second vehicle state information may include vehicle identification information, vehicle type, charging demand, charging pressure requirement, current charging state, vehicle recovery time, and the like, and the vehicle recovery time may mean a time to find a vehicle. The first vehicle state information and the second vehicle state information may be different information or may be the same information.

In addition, when the FCEV 1 is waiting for charging, the terminal device 300 may request a vehicle inspection/maintenance service and request an autonomous parking mode after charging. Here, the self-parking mode after charging may be a mode in which the vehicle autonomously parks in a nearby parking lot after charging and notifies the driver of the parking location. For example, if the hydrogen fuel cell vehicle 1 is an autonomous vehicle, the autonomous vehicle can be on standby and automatically move to the charging device 15 to be charged when it is the turn to charge, and after charging is completed, it can be placed in a specific location. It parks and informs the driver of the parking location of the vehicle. At this time, the hydrogen fuel cell vehicle 1 may inform the driver of the parking location using a text message, SNS, or the like.

This charging device 15 displays billing information to be paid by the user in response to the charging speed, charging status, charging completion state, and charging amount of the hydrogen fuel cell vehicle 1 through a display unit (not shown), or the hydrogen fuel cell vehicle 1 or It can be transmitted to the terminal device 300. Since this configuration is a basic configuration of the charging device 15 and is obvious to those skilled in the art, a description thereof will be omitted.

The charging device 15 may transmit an operating state signal of the charging device 15 to the charging station server 100 upon request of the charging station server 100 .

The charging device 15 may control the fuel cell of the hydrogen-powered vehicle 1 to be charged by different charging methods depending on the type of vehicle. Here, the charging method may be a different charging algorithm according to the type of fuel cell (battery). For example, the charging device 15 stores fuel cell types for each vehicle type and an optimal charging algorithm method for each fuel cell type. Accordingly, the charging device 15 may determine the fuel cell (battery) type according to the recognized vehicle type and determine a charging algorithm according to the corresponding fuel cell type.

Depending on the type of vehicle, the type of fuel cell installed inside is very diverse. In addition, even for the same fuel cell, the charging algorithm that can use the optimal lifespan is different depending on the manufacturer.

Therefore, the charging device 15 recognizes the type of vehicle approaching or connected to the charging device 15, determines the type of fuel cell according to the type of vehicle, and then applies the optimized charging algorithm differently according to the type of fuel cell, thereby increasing the lifespan of the fuel cell. That is, the life of the hydrogen fuel cell vehicle 1 can be extended and used as much as possible.

In addition, the charging device 15 acquires an image including a vehicle (hereinafter referred to as a 'charging station image') from the image acquisition device 200, and recognizes the type of vehicle through the charging station image to determine a charging method. there is. In addition, the charging device 15 may receive a charging method of a vehicle approaching or connected to the corresponding charging device 15 from the charging station server 100 and then control the fuel cell of the vehicle to be charged using the received charging method. In this case, the charging station server 100 analyzes the image of the charging station approaching or connected to the charging device 15, and the charging method may be determined and transmitted to the charging device 15.

In addition, the charging device 15 may transmit the charging status to the terminal device 300 when charging the fuel cell of the FCEV 1. Here, the charging status may include at least one of a charging progress status and an expected time until fully charged. Also, the charging status may include a charging completion status.

In addition, the charging device 15 applies a penalty when a certain period of time (eg, 30 minutes, 1 hour, etc.) has elapsed since the charging status (eg, charging completion status) is transmitted to the terminal device 300. You can also do billing. In this case, as the elapsed time becomes longer, the penalty may be applied differently to perform billing.

Since the fuel cell charging time is relatively long in the case of the hydrogen electric vehicle 1, the vehicle driver generally does not wait at the charging station 10 during the time the fuel cell is being charged. At this time, when the vehicle driver occupies the charging device 15 as it is even after the fuel cell is fully charged, a situation occurs in which other vehicle drivers cannot charge and wait. Therefore, if the vehicle is not moved for a certain period of time after the charging status, such as the charging completion state, is transmitted to the terminal device 300, a penalty is applied to perform additional charging, thereby preventing the charging device 15 from being occupied. You may.

Here, the second vehicle state information may include vehicle identification information, vehicle model, required charging amount, required charging pressure, current charging state, vehicle recovery time, and the like. That is, the charging station server 100 receives the second vehicle state information from the FCEV 1 entering the charging station 10, analyzes the charging station image obtained through the image capture device 200, and analyzes the vehicle type of the vehicle waiting to be charged. and the number of vehicles waiting to be charged, and the expected charging waiting time of the vehicles waiting to be charged may be calculated based on the vehicle state information and the number of vehicles waiting to be charged.

For example, when a first FCEV with a vehicle recovery time of 15:00 and a second FCEV with a vehicle collection time of 18:00 enter the charging station 10 at the same time, the charging station server 100 sets the charging order of the first FCEV to the second FCEV. can be done faster than the charging sequence of

In addition, the charging station server 100 may interwork with the image capture device 200 to monitor an abnormal situation in real time and notify the terminal device 300 of an abnormal situation when an abnormal situation is detected. Here, the abnormal situation may include, for example, all abnormal situations such as vehicle damage, charging station fire, and vehicle fire. Of course, monitoring for an abnormal situation may be performed by the charging station management server 400 as well.

In addition, the charging station server 100 can automate protocol selection when charging the FCEV 1. That is, the charging station server 100 may automatically select a different charging protocol according to the case of charging one vehicle with one charging device 15 or the case of simultaneously charging a plurality of vehicles.

In addition, the charging station server 100 may optimize the operation of charging station facilities. That is, the charging station server 100 may optimize the operation of the charging device 15 according to the required amount of charging pressure of the FCEV 1.

In addition, the charging station server 100 interworks with the image acquisition device 200 to obtain a charging station image from the image acquisition device 200 in real time, analyzes it, determines a charging method according to the vehicle type, and determines the charging device 15 can be sent to

The charging management server 400 remotely controls the charging device 15 and the charging station server 100 installed in each charging station 10 .

2 is a block diagram schematically showing the configuration of a charging station server according to an embodiment of the present invention, and FIG. 3 is an exemplary diagram for explaining a charging protocol according to an embodiment of the present invention.

Referring to FIG. 2 , the charging station server 100 according to an embodiment of the present invention includes a communication unit 110, a vehicle waiting to be charged information analyzer 120, a charging support unit 130, a charging monitoring unit 140, an additional It includes a service unit 150, a storage unit 160, and a light control unit 170. Depending on the method of implementing the present invention, each component may be combined with each other and provided as one, and also some components may be omitted depending on the method of implementing the present invention.

The communication unit 110 is a means for transmitting and receiving data with other devices through a communication network. That is, the communication unit 110 may receive an image of a charging station in real time by interworking with the image capture device 200 . Also, the communication unit 110 may receive information about the current charging device from the charging device 15 . In addition, the communication unit 110 may transmit current state information of the charging station 10 to the charging management server 400 .

The vehicle waiting to be charged information analyzer 120 receives the second vehicle state information from the FCEV 1 that has entered the charging station 10, and analyzes the image of the charging station obtained through the image acquisition device 200 to determine the vehicle waiting to be charged. The type and number of vehicles are recognized, and the expected charging waiting time of the vehicles waiting to be charged may be calculated based on the second vehicle state information and the number of vehicles waiting to be charged. Here, the second vehicle state information may include vehicle identification information, a vehicle type, a required charging amount, a required charging pressure, a current charging state, a vehicle collection time, and a scheduled charging time. Also, the second vehicle condition information may further include a vehicle inspection/maintenance service request. In addition, when the hydrogen fuel cell vehicle 1 is an autonomous vehicle, the second vehicle state information may include an autonomous parking mode. The autonomous parking mode may refer to a mode in which the vehicle is automatically moved to a charging device to be charged when it is the turn of charging, and automatically parks in a specific location after charging is completed.

In addition, the vehicle waiting to be charged information analyzer 120 checks the type and number of vehicles waiting to be charged based on the second vehicle state information and the image of the charging station, calculates the waiting time for charging for each charging device (dispenser), and the charging station 10 Current status including at least one of identification information of ), the number of charging devices (dispensers), charging status, charging device (dispenser) usage status, the number of currently reserved/waiting vehicles, and expected charging waiting time per charging device (dispenser) Information may be transmitted to the charging management server 400 .

The waiting vehicle information analysis unit 120 receives the charging station image from the image acquisition device 200 installed in the charging station 10, and compares the vehicle number information extracted from the charging station image with the pre-stored registered vehicle number to find a matching number. In this case, communication with the vehicle is performed by determining the vehicle as a vehicle waiting for charging, and communication with the corresponding vehicle can be prevented if there is no matching number.

The charging support unit 130 may determine a charging method according to the vehicle type of the vehicle waiting to be charged, and control the vehicle to be charged using the determined charging method. That is, the charging support unit 130 may analyze an image of a charging station to recognize a vehicle type, determine a charging method according to the recognized vehicle type, and transmit the corresponding vehicle to the charging device 15 to be charged.

In addition, the charging support unit 130 can automate protocol selection when charging the FCEV 1. That is, the charging support unit 130 may automatically select a different charging protocol according to the case of charging one vehicle with one charging device 15 or the case of simultaneously charging multiple vehicles.

For example, when vehicles sequentially enter, the charging support unit 130 may charge using a flow rate pattern protocol corresponding to graph M shown in FIG. 3 . Graph M may be a graph in which charging is performed in a flow rate pattern in which, when charging starts, the flow rate gradually increases and then decreases to complete charging.

When the FCEVs 1 are entered in parallel at the same time, the charging support unit 130 can simultaneously charge the charging time at the same time by reducing the charging flow rate at the beginning of charging and increasing the charging amount at the second half. In the case of simultaneously charging two vehicles, the total flow rate capable of simultaneously charging two vehicles can be secured only when the flow rate at which the two M graph patterns overlap is reached. However, it is not necessary to follow the flow rate pattern in which two M graph patterns overlap in order to meet the prescribed charging time when charging two vehicles at the same time. Therefore, when two vehicles are to be charged simultaneously, the charging support unit 130 can simultaneously charge the same charging time by reducing the flow rate charging amount in the early stage of charging and increasing the charging amount in the second half.

In addition, the charging support unit 130 may optimize the operation of charging station facilities. That is, the charging support unit 130 may optimize the operation of the charging device 15 according to the required charging pressure of the FCEV 1.

For example, it will be described assuming that the first vehicle in the charging standby state wants full load charging of 50 to 700 bar and the second vehicle has requested charging of 50 to 300 bar. In this case, the charging support unit 130 may control the pressure so that full load charging is performed when charging the first vehicle, and may control the pressure to be maintained at 300 bar when charging the second vehicle.

In the case of high-pressure, medium-pressure, and low-pressure charging or direct charging by directly operating a compressor, if the pressure type and charging pressure of the vehicle waiting for charging are known before charging the vehicle, the charging state can be checked to charge each vehicle at the optimal value. can fit The vehicle transmits the second vehicle state information including the charging pressure to the charging station server 100 (charging device 15), so the charging station server 100 can know the charging pressure before charging the vehicle. Accordingly, the charging support unit 130 may optimize the operation of the charging device 15 according to the required charging pressure of the vehicle.

The charging monitoring unit 140 may transmit billing information to be paid by the user to the hydrogen fuel cell vehicle 1 or the terminal device 300 in response to the charging speed, charging status, charging completion state, and charging amount of the hydrogen fuel cell vehicle 1. .

In addition, when charging the fuel cell of the FCEV 1 through the charging device 15, the charging monitoring unit 140 may transmit the charging status to the terminal device 300. Here, the charging status may include at least one of a charging progress status and an expected time until fully charged. Also, the charging status may include a charging completion status.

In addition, the charging monitoring unit 140 applies a penalty when a predetermined time (eg, 30 minutes, 1 hour, etc.) has elapsed after the charging status (eg, charging completion status) is transmitted to the terminal device 300.
