Further, the voltage regulator 15 is connected to the controller 12 by a wire, which is used to adjust the output voltage, and the upstream of the relay 16 is connected to the voltage regulator 15 by a wire, and the downstream is connected to the transmitting device by a wire, thereby, the circuit can be controlled to be opened or disconnected, so as to realize that the transmitting device sends electric energy to the outside or stops sending electric energy.

[0055] Preferably, the model of the processor 13 is MT6995, the model of the controller 12 is SPC-STW-26A1, the model of the voltage regulator 15 is R1561, and the model of the relay 16 is JRC-5M / RG4.527.168.

[0056] In an optional technical solution of this embodiment, the transmitting device includes a transmitting coil 11 , which is connected to a relay 16 ; the receiving device includes a receiving coil 9 , which is suitable for matching with the transmitting coil 11 .

[0057] Specifically, the transmitting device includes a transmitting coil 11, and the receiving device includes a receiving coil 9. When the transmitting coil 11 is powered, it can send electric energy to the receiving coil 9. After the electric energy is received by the receiving coil 9, it is transmitted to the battery of the new energy vehicle 1 for storage to realize the wireless charging process. It should be noted here that the working principle of the transmitting coil 11 and the receiving coil 9 and the wireless charging principle in this embodiment can adopt the existing technology, which will not be elaborated here.

[0058] In the optional technical solution of this embodiment, the detection device includes a distance sensor 3 and a power detector 10; the distance sensor 3 is arranged at a position close to the transmitting device, and the distance sensor 3 is connected to the processor 13; the power detector 10 is arranged on the new energy vehicle 1, and is used to send a power status signal of the new energy vehicle 1 to the processor 13.

[0063] In addition, the power detector 10 is arranged on the new energy vehicle 1, and the power status of the battery of the new energy vehicle 1 is monitored in real time through the power detector 10. Since the power detector 10 is connected to the second wireless communicator 14, the power status and charging status of the battery can be fed back to the second wireless communicator 14 in real time, and transmitted to the first wireless communicator 8 via the second wireless communicator 14, and finally transmitted to the processor 13 by the first wireless communicator 8 for analysis and judgment.

For example, when it is necessary to select a model of a new energy vehicle 1, the corresponding brand, model, etc. can be found on the control panel 6, or the charging consumption amount, charging time, charging amount, etc. can also be selected on the control panel 6. The above selection parameters can be input through the control panel 6, and then analyzed and judged by the processor 13, and finally the controller 12 controls the corresponding output working condition.

[0067] The charging system provided in this embodiment can realize wireless charging of different new energy vehicles 1, thereby improving the applicability of the system.

[0068] In an optional technical solution of this embodiment, the charging system includes a power adapter 17 , which is arranged near the transmitting device and connected to the controller 12 for adapting power to the controller 12 .

[0069] Preferably, the model of the power adapter 17 is LYD0502000.

[0070] In the optional technical solution of this embodiment, the transmitting device is arranged in the transmitting box 4, and the receiving device is arranged in the receiving box 2. In addition, the transmitting box 4 is also provided with a relay 16, a voltage regulator 15, a power adapter 17, a controller 12, a processor 13, a first wireless communicator 8, etc., and these electrical components are fixed in the transmitting box 4 by screws; and the receiving box 2 is also provided with a second wireless communicator 14, a power detector 10, etc., and these electrical components are fixed in the receiving box 2 by screws.

[0071] The working principle of the charging system provided in this embodiment is:

[0072] The charging system is connected to the power supply, and the model of the new energy vehicle 1 to be charged is selected and set through the control panel 6. After setting, the car is driven to the designated area, the charging system is started, and the distance sensor 3 can detect and feedback the distance between the new energy vehicle 1 and the designated area. When the car enters the designated area, the alarm element sounds an alarm. At the same time, a prompt alarm is also issued through the wireless communication car system (refer to the prior art); then, the relay 16 in the control device is energized and closed, and wireless charging begins. When it is fully charged, the relay 16 is disconnected, thereby completing the charging process.

[0073] This embodiment provides a charging method based on the above charging system, including the following steps:

[0074] The user sets the model of the new energy vehicle 1 to be charged on the control panel 6;

[0075] The user drives the new energy vehicle 1 to a designated charging area so that the receiving device on the new energy vehicle 1 is within the reach of the transmitting device;

[0076] Charging system starts;

[0077] The distance sensor 3 in the detection device detects the distance between the new energy vehicle 1 and the charging system, and transmits the distance signal to the control device for analysis and judgment;

[0078] The power detector 10 in the detection device detects the power of the new energy vehicle 1 and transmits a power status signal to the control device, which analyzes and determines the power;

[0079] When the control device determines that the distance between the new energy vehicle 1 and the charging system meets the preset requirement and the power of the new energy vehicle 1 is not full, the control device controls the transmitting coil 11 in the transmitting device to send electric energy to the receiving coil 9 in the receiving device to charge the new energy vehicle 1;

[0080] When the battery is fully charged, the control device controls the transmitting coil 11 in the transmitting device to stop transmitting electrical energy to the receiving coil 9 in the receiving device.

[0081] Specifically, when charging is needed, the user drives the new energy vehicle 1 to an area close to the charging system, and inputs his own vehicle model on the distance sensor 3. After setting, the new energy vehicle 1 is driven to a designated area, such as a designated parking space, and the vehicle is parked and the engine is turned off. When the charging system is started, the position sensor in the charging system detects the new energy vehicle 1, and transmits the position information of the new energy vehicle 1 to the processor 13 of the control device for analysis and judgment. When the processor 13 determines that the new energy vehicle 1 has reached the charging range (the area covered by the transmitting device), the signal is transmitted to the controller 12. At the same time, the power detector 10 also transmits the detected power status of the new energy vehicle 1 to the processor 13 for analysis and judgment. When the processor 13 determines that the power is not full, the signal is transmitted to the controller 12, and then the controller 12 finally controls the transmitting coil 11 in the transmitting device to send power outward through some electrical control elements, and the receiving coil 9 in the receiving device on the new energy vehicle 1 can receive power, thereby charging the new energy vehicle 1.

[0082] During the charging process, the power detector 10 detects the power level of the new energy vehicle 1 in real time, and sends the power level signal to the processor 13 in real time, which is analyzed and judged by the processor 13; when the processor 13 determines that the power is full, the signal is transmitted to the controller 12, and the controller 12 finally controls the transmitting coil 11 in the transmitting device to stop sending power to the outside through some electrical control elements, thereby completing the charging process.

[0083] After the user pays, he can drive away the new energy vehicle 1. It should be noted here that the payment principle can refer to the existing technology and will not be elaborated here.

[0084] In addition, the charging method is based on the above-mentioned charging system. Therefore, the technical advantages and effects achieved by the charging method include the technical advantages and effects achieved by the above-mentioned charging system, which will not be repeated here.

[0085] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
