[0002] The present invention relates to an electric vehicle charging system and a server for supporting electric vehicle charging, and more specifically, to an electric vehicle charging system and a server for supporting electric vehicle charging that can supply emergency power to an electric vehicle using a drone equipped with a battery.

[0003] Consumer interest and demand for electric vehicles are increasing as they emerge as the most effective alternative for reducing greenhouse gas emissions and improving energy efficiency. Unlike conventional internal combustion engine vehicles, electric vehicles (EVs) require components such as batteries, electric motors, inverters, converters, and Battery Management Systems (BMS).

[0004] Rechargeable secondary batteries are used for electric vehicles. Secondary batteries, which can be recharged and reused after use, are manufactured as battery modules or battery packs by electrically connecting multiple battery cells according to the output capacity required by the device, and are used as power sources for various devices. Secondary batteries are used in a wide range of fields, from small high-tech electronic devices such as smartphones to electric bicycles, electric vehicles, and Energy Storage Systems (ESS).

[0005] A prerequisite for the widespread adoption of electric vehicles is the establishment of charging infrastructure, including electric vehicle charging stations. Electric vehicle charging stations generally receive power from the power grid or solar power generation facilities to charge electric vehicles. Recently, considering power variability due to weather and time of day, electric vehicle charging stations have emerged that store grid power or solar power in an ESS and utilize the ESS as an additional power source to charge electric vehicles.

[0006] When the battery's State of Charge (SOC) drops, electric vehicles must move to an electric vehicle charging station to charge. However, if it is impossible to reach an electric vehicle charging station with the remaining SOC, charging support is required to extend the driving range sufficient to reach the charging station.

[0007] A related prior art is KR 2023-0114771 A.

[0046]

[0047] FIG. 1 is a diagram showing the configuration of an electric vehicle charging system according to an embodiment of the present invention.

[0048] Referring to FIG. 1, the electric vehicle charging system may include a server (100) and a drone (200). Here, the server (100) may be connected to the drone (200) and a user terminal (300) via a network, and the user terminal (300) may be connected to the electric vehicle (400) via a network.

[0049] The server (100) is a computing device that performs a series of operations to support charging of an electric vehicle (400) in conjunction with a drone (200) and a user terminal (300). Here, the server (100) may be managed by a company that provides electric vehicle charging services.

[0050] The drone (200) is an unmanned aerial vehicle that operates using power stored in an internal battery as the driving power. Here, the drone (200) may be equipped with a battery, an autonomous flight module, a GPS module, a control module, and a communication module inside the main body.

[0051] The drone (200) can operate according to a control signal received from the server (100) or move to a location corresponding to the location coordinates received from the server (100) using an autonomous flight module.

[0052] A drone (200) according to an embodiment of the present invention may be equipped with a wireless charging pad.

[0053] The wireless charging pad may be formed of a flexible material and may include a power transmission coil inside. The power transmission coil may be electrically connected to a battery provided inside the drone (200). When the drone (200) receives a power supply start signal from the server (100), it may output the stored power of the battery to apply current to the power transmission coil.

[0054] The wireless charging pad may be formed as a rollable structure. Here, the wireless charging pad may be unfolded by a user. Alternatively, the wireless charging pad may be fixedly supported on the drone (200) by a fixed unit, and configured to unfold downward when the fixed unit is released.

[0055] The user terminal (300) is a computing device used by the electric vehicle driver. For example, the user terminal (300) may be the electric vehicle driver's mobile phone, tablet PC, or the electric vehicle's navigation device.

[0056] A user terminal (300) is connected to an electric vehicle (400) via a network and can collect status information of the electric vehicle (400).

[0062]

[0063] FIG. 2 is a diagram showing the configuration of a drone according to an embodiment of the present invention, and FIG. 3 is a diagram showing the structure of a wireless charging pad according to an embodiment of the present invention.

[0064] Referring to FIG. 2, the drone (200) may include a main body (210) and one or more wings (220) attached to the main body (210).

[0065] Inside the main body (210), a battery, an autonomous flight module, a GPS module, a control module, and a communication module may be provided.

[0066] A wireless charging pad (230) may be mounted on the drone (200). Additionally, the drone (200) may include a fixing unit (240) that fixes and supports the wireless charging pad (230).

[0067] The fixed unit (240) can be attached to and detachably coupled with the main body (210) while covering at least a portion of the outer surface of the wireless charging pad (230). Here, the fixed unit (240) can be controlled by a control module, and when controlled to be detached, the other end is detached from the main body (210) while one end is fixed to the main body (210), so that the wireless charging pad (230) can be separated from the drone (200).

[0068] The wireless charging pad (230) is formed of a flexible material and may include a power transmission coil inside. The power transmission coil may be electrically connected to a battery provided inside the drone (200).

[0069] Referring to FIG. 3, the wireless charging pad (230) may be formed as a rollable structure.

When the charging of the electric vehicle (400) is completed, the drone (200) can wind and retrieve the wireless charging pad (230) through the winding unit and control the fixing unit (240) to fix the retrieved wireless charging pad (230) to the main body (210).

[0072]

[0073] FIG. 4 is a flowchart of the operation of an electric vehicle charging support method according to an embodiment of the present invention, and FIGS. 5 to 7 are reference diagrams for explaining an electric vehicle charging support method according to an embodiment of the present invention.

[0074] An electric vehicle charging support method according to an embodiment of the present invention can be performed by a drone including a battery and a wireless charging pad; and a server linked with a user terminal of an electric vehicle driver.

[0075] When the server receives a request to call the drone from the user terminal (S410), the server can control the drone so that the drone moves to the location of the electric vehicle (S420).

[0076] Specifically, the user terminal can transmit call request information for a drone to a server for charging support of an electric vehicle. Here, the call request information includes location information of the electric vehicle and may further include one or more of the electric vehicle battery's SOC, driving range, and requested charge amount. Meanwhile, the user terminal may receive the information included in the call request information from the electric vehicle driver or collect it from the electric vehicle.

[0077] When the server receives call request information from a user terminal, it can control the drone so that the drone moves to the location included in the call request information. For example, if the server transmits the location information of an electric vehicle to the drone, the drone can move to the location of the electric vehicle using an autonomous flight module. As another example, the server can control the drone in real time based on the location information of the electric vehicle and the drone so that the drone moves to the location of the electric vehicle.

[0078] When the drone moves to the location of the electric vehicle, the server can control the drone to hover above the electric vehicle. In other words, the drone can hover and wait above the electric vehicle to supply power.

[0079] When the drone moves to the location of the electric vehicle, the server can control the drone so that it supplies power stored in the battery to the electric vehicle using a wireless charging pad.

[0080] Specifically, the server can control the wireless charging pad mounted on the drone to be detached (S430), and then control the drone so that the electric vehicle is charged through the wireless charging pad (S440).

[0081] For example, the server may transmit a signal to the drone to release the fixed support of the wireless charging pad so that the wireless charging pad formed as a rollable structure can be unfolded. While in a hovering flight state, the drone releases the fixed unit that supports the wireless charging pad, and accordingly, the wireless charging pad can be separated from the drone body and unfolded downward. Subsequently, as shown in FIGS. 5 and 6, the wireless charging pad (220) can be placed by the electric vehicle driver at a position corresponding to the wireless charging unit (410) located at the bottom of the electric vehicle (400). The drone can output the stored power of the battery to the wireless charging pad (220) according to the power output control signal of the server, so that the electric vehicle battery can be charged.

[0082] In S440, when the server receives a charging request signal from the user terminal, it can transmit a power output control signal to the drone so that power stored in the battery is supplied to the electric vehicle. Here, the charging request signal is a signal indicating that the electric vehicle is ready to charge, and can be input by the user to the user terminal.

[0083] For example, as illustrated in FIGS. 5 and 6, when the wireless charging pad (220) is properly positioned at a location corresponding to the wireless charging unit (410) and the charging preparation is complete, the electric vehicle driver can input the start of charging to the user terminal. Subsequently, the user terminal can request the start of electric vehicle charging using the drone by transmitting a charging request signal to the server, and the server can send a power output control signal to the drone so that the drone outputs the stored power of the battery to the wireless charging pad.

[0084] In S420, when the drone moves to the location of the electric vehicle, the server can control the drone to land on the upper surface of the electric vehicle. That is, the drone can land on the upper surface of the electric vehicle and perform charging of the electric vehicle. Here, the server can identify the electric vehicle based on vehicle identification information received from the user terminal and control the drone to land on the upper surface of the identified electric vehicle.

[0085] For example, the server can receive a vehicle number from a user terminal and receive a video captured by a camera module mounted on a drone to identify an electric vehicle requesting charging. Here, the server can use an image analysis algorithm to identify an electric vehicle having the same vehicle number as the received vehicle number. Subsequently, the server can use an image analysis algorithm to identify the top surface of the electric vehicle and control the drone to land on the top surface of the electric vehicle. As illustrated in FIG. 7, once the landing of the drone is complete, the server can control the wireless charging pad mounted on the drone to be detached and then control the drone to charge the electric vehicle through the wireless charging pad.

[0086] In S440, the server can determine the amount of charge for an electric vehicle based on one or more of the drone battery's SOC, the electric vehicle battery's SOC, the driving range, the requested charge amount, and the distance between the electric vehicle and the electric vehicle charging station. For example, the server can calculate the amount of charge that enables the electric vehicle to drive to the nearest electric vehicle charging station based on the electric vehicle battery's SOC, the driving range, and the distance between the electric vehicle and the nearest electric vehicle charging station.

[0087] When charging of the electric vehicle is completed, a signal for winding the wireless charging pad can be transmitted to the drone so that the wireless charging pad is retrieved. Subsequently, the drone can operate the winding unit to wind and retrieve the unfolded wireless charging pad, and control the fixing unit to secure the retrieved wireless charging pad to the drone body.

[0088]
