[0020] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. The described embodiments are merely some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0021] In the technical solution of this utility model, Figure 1 and Figure 2 This is a structural diagram illustrating the specific structure of an electric vehicle charging station with both wireless and wired charging functions according to this utility model. It should be noted that the solid lines in the diagram represent power supply lines, and the dashed lines represent communication lines. Figure 1 and Figure 2 As shown, this utility model includes:

[0022] The system comprises a charging pile housing 1, a DC charging gun 2, a crash barrier beam 3, a wireless charging transmitter module 4, and a transmitter coil 5. The wireless charging transmitter module 4 is installed inside the charging pile housing 1. A rectifier and voltage regulation module 6 is installed inside the charging pile housing 1. The power input terminals of both the wireless charging transmitter module 4 and the DC charging gun 2 are connected to the power output terminal of the rectifier and voltage regulation module 6. The transmitter coil 5 is connected to the output terminal of the wireless charging transmitter module 4. The crash barrier beam 3 is installed in the parking space, and the transmitter coil 5 is installed on the side of the crash barrier beam 3 furthest from the vehicle.

[0023] The transmitting coil 5 is positioned on the back of the bumper beam, away from the vehicle, to prevent it from being accidentally run over by the vehicle. It also offers some positional adjustment, facilitating better alignment with different car models during installation. The DC charging method eliminates the need for an AC charger in the car, saving on vehicle costs and space.

[0024] The charging pile housing 1 can be upright or wall-mounted.

[0025] The charging control module 11 of the charging pile is installed in the charging pile 1 and is a power supply control component. Its main components include fuses and relays. The input terminal of the fuse is connected to the power supply, and the output terminal is connected to the input terminal of the relay. The output terminal of the relay is connected to the input terminal of the rectifier and voltage regulating module 6, and the control terminal of the relay is connected to the control unit. The control unit mainly controls the switching of the relays, thereby controlling the power input. The fuse mainly protects the entire charging pile in case of overcurrent.

[0026] It should be noted that this utility model has two applications in the actual market. The first is the sale of the entire charging pile, which includes all the structures of the charging pile described in this utility model. The second is an improvement on existing commercial DC charging piles. In this case, only the wireless charging transmitter module 4 and the transmitter coil 5 need to be installed on the existing commercial charging pile, utilizing the rectification and voltage regulation devices built into the commercial DC charging pile, without the need to add an additional rectification and voltage regulation module. Whether it is a complete charging pile or an improvement on an existing commercial charging pile, the structure of the charging pile includes the charging pile shell 1, DC charging gun 2, anti-collision ground beam 3, wireless charging transmitter module 4 and transmitter coil 5, rectification and voltage regulation module 6, etc. Therefore, regardless of the form of market application, as long as the final charging pile includes the above structures, it falls within the protection scope of this utility model.

[0027] In one embodiment of this utility model, the rectifier voltage regulating module 6 can be a PFC power supply. The PFC power supply has a voltage regulation function, which can output corresponding charging voltage and current according to the different needs of the charging vehicle. The input terminal of the charging pile can be connected to AC single-phase 220V or three-phase 380V mains power. The diagram is for reference only. The transmitting coil 5 is wirelessly charged from bottom to top towards the receiving coil at the bottom of the vehicle's trunk, without any physical connection in between.

[0028] In one embodiment of this utility model, positioning components 8 are provided on both sides of the anti-collision ground beam 3. The positioning components 8 can be indicator lights, which can act as positioning anchor points when the new energy vehicle automatically parks, thereby achieving more accurate positioning and parking. In abnormal situations, the positioning components 8 can also serve as light-emitting warnings.

[0029] In one embodiment of this utility model, the charging pile 1 is further provided with a control unit 12, the communication port of the DC charging gun 2 is connected to the control unit 12, and the control unit 12 is connected to the charging control module 11.

[0030] In one embodiment of this utility model, the wireless charging transmitter module 4 includes: a main control module 43, an inverter circuit 41, and a resonant circuit 42. The input terminal of the inverter circuit 41 is connected to the power output terminal of the charging control module 11, the output terminal of the inverter circuit 41 is connected to the input terminal of the resonant circuit 42, and the output terminal of the resonant circuit 42 is connected to the transmitting coil 5. The main control module 43 is connected to the on-board wireless charging control module 9 of the electric vehicle, the control unit 12 in the charging pile 1, and the control terminal of the inverter circuit 41. The control unit 12 in the charging pile 1 is connected to the charging control module 11.

[0031] In this invention, when an electric vehicle is wirelessly charged, and the electric vehicle enters a designated area, the main control module 43 in the wireless communication transmitting module communicates wirelessly with the on-board wireless charging control module 9 of the electric vehicle to perform pre-charging authentication. After successful authentication, the main control module 43 communicates wiredly with the control unit 12 in the charging pile 1 to notify the control unit 12 to start charging. The control unit 12 then controls the charging control module 11 to start, thereby providing power to the wireless charging transmitting module 4.

[0032] During wired charging, the electric vehicle verifies its connection to the control unit 12 via the communication port of the DC charging gun 2. Upon successful verification, the control unit 12 controls the charging control module 11 to switch on and off, thus enabling wired charging. The main control module 43 is also connected to the control terminal of the inverter circuit 41, allowing it to directly control the inverter circuit 41 to stop operating and disconnect wireless charging when necessary. When the DC charging gun 2 is inserted for wired charging, the inverter circuit needs to be disconnected, preventing the transmitting coil from emitting electrical energy.

[0033] It should be noted that the main control module 43 and the control unit 12 mentioned above can be MCUs, microcontrollers, etc., equipped with wireless communication modules.

[0034] The on-board wireless charging control module 9 of the electric vehicle can also be an MCU, microcontroller or other device with a wireless communication module, which is used to control the on-board wireless charging receiving component. The on-board wireless charging receiving component generally includes: receiving coil, resonant module, rectifier module, switch module, etc. The specific connection structure is a conventional technical means in this field, so it will not be described in detail here.

[0035] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
