[0004] According to a first aspect of the present invention, a method for wireless charging and identification of electric vehicles is provided, comprising:
[0005] A mobile phone with an NFC communication module is placed on the wireless charging bracket of an electric vehicle. The wireless charging bracket is equipped with an NFC coil to enable NFC communication between the mobile phone and the electric vehicle's processor.

[0007] If the phone's NFC ID can be found in the whitelist, the electric vehicle's power is turned on, and the wireless charging function of the electric vehicle is activated simultaneously. The phone is then charged through the coupling between the NFC coil in the wireless charging bracket and the NFC coil of the phone's NFC communication module.
[0008] Preferably, it further includes:
[0009] Turn on the electric vehicle's power, connect the mobile phone with the NFC communication module to the electric vehicle via Bluetooth, read the mobile phone's NFC ID number, and send the mobile phone's NFC ID number to the mobile phone via Bluetooth. The user adds the NFC ID number to the electric vehicle's whitelist on the mobile phone, and sends the electric vehicle's whitelist to the electric vehicle's processor via Bluetooth. The electric vehicle's processor stores the electric vehicle's whitelist.
[0010] Preferably,
[0011] The NFC coil in the NFC communication module of the mobile phone and the NFC coil in the wireless charging bracket use multi-frequency antennas, and the frequency bands for wireless charging and NFC communication are set respectively.
[0012] The wireless charging frequency band of the NFC coil in the NFC communication module of the mobile phone is the same as the wireless charging frequency band of the NFC coil in the wireless charging stand.

[0016] Preferably,
[0017] The electric vehicle whitelist includes multiple NFC ID numbers.
[0018] According to a second aspect of the present invention, a wireless charging and identification device for electric vehicles is provided, comprising:
[0019] NFC communication connection module: used to place a mobile phone with an NFC communication module on the wireless charging bracket of an electric vehicle. The wireless charging bracket is equipped with an NFC coil to enable NFC communication between the mobile phone and the electric vehicle processor.
[0020] NFC ID lookup module: Used to obtain the NFC ID number of the mobile phone and search for that NFC ID number in the whitelist;
[0021] Wireless charging activation module: If the NFC ID number of the mobile phone can be found in the whitelist, the power of the electric vehicle is turned on and the wireless charging function of the electric vehicle is started simultaneously. The NFC coil in the wireless charging bracket is coupled with the NFC coil of the mobile phone's NFC communication module to charge the mobile phone.

[0025] The technical solutions provided by the embodiments of the present invention may include the following beneficial effects:
[0026] This application utilizes NFC communication and wireless charging technologies. By identifying the NFC ID number of a user's mobile phone, it determines whether the user is a registered user. For registered users, the electric vehicle processor directly starts the electric vehicle's power supply, eliminating the need for the user to use a key. Users simply need to place their phone on the wireless charging holder, saving time, especially for delivery or logistics electric vehicle users where time is money. Furthermore, eliminating the need for a key to start or stop the electric vehicle effectively extends the lifespan of the key interface. Simultaneously, once the electric vehicle's power is on, the wireless charging function is activated. Through the coupling of two NFC coils operating at the same frequency, the phone is wirelessly charged. This addresses the issues of insufficient battery life due to continuous phone use by delivery and logistics electric vehicle owners, and the reduced lifespan of the phone's charging interface caused by constant plugging and unplugging of charging cables.
[0027] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit the invention. Attached Figure Description
[0028] The accompanying drawings, which are incorporated in and form part of this specification, illustrate embodiments consistent with the invention and, together with the description, serve to explain the principles of the invention.
[0029] Figure 1 This is a flowchart illustrating a wireless charging and identification method for electric vehicles according to an exemplary embodiment;
[0030] Figure 2 This is a schematic diagram of a wireless charging and identification device for an electric vehicle according to another exemplary embodiment;
[0031] In the attached diagram: 1-NFC communication connection module, 2-NFC ID query module, 3-wireless charging start-up module. Detailed Implementation
[0032] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.
[0033] Example 1
[0034] Figure 1This is a flowchart illustrating a wireless charging and identification method for electric vehicles according to an exemplary embodiment, such as... Figure 1 As shown, it includes:
[0035] S1, Place a mobile phone with an NFC communication module on the wireless charging bracket of the electric vehicle. The wireless charging bracket is equipped with an NFC coil to enable NFC communication between the mobile phone and the electric vehicle processor.
[0036] S2, obtain the phone's NFC ID number and search for that NFC ID number in the whitelist;
[0037] S3. If the NFC ID number of the phone can be found in the whitelist, start the electric vehicle power supply and simultaneously start the wireless charging function of the electric vehicle. Charge the phone by coupling the NFC coil in the wireless charging bracket with the NFC coil of the phone's NFC communication module.
[0038] Understandably, this application uses NFC communication technology and wireless charging technology. By identifying the NFC ID number of the user's mobile phone, it determines whether the user is a registered user. For registered users, the electric vehicle processor directly starts the electric vehicle power supply, eliminating the need for the user to start the power supply with a key. The user only needs to place the mobile phone on the wireless charging bracket of the electric vehicle, saving the user's time. This is especially important for users of electric vehicles used for logistics or food delivery, where time is money. Furthermore, not needing to start or stop the electric vehicle with a key can effectively extend the lifespan of the electric vehicle key interface. At the same time, when the electric vehicle power supply is started, the wireless charging function is activated. Through the coupling of two NFC coils of the same frequency band, the purpose of wirelessly charging the mobile phone is achieved. This also solves the problems of insufficient mobile phone battery caused by continuous use of mobile phones by food delivery and logistics electric vehicle owners, as well as the reduced lifespan of the mobile phone charging interface caused by the need to constantly plug and unplug the charging cable.
[0039] The electric vehicle of this application uses a 24V DC power supply. The DC power output from the 24V DC power supply is processed by the wireless charging module and then converted into high-frequency AC power by a 2M active crystal oscillator inverter. This AC power is supplied to the NFC coil in the wireless charging bracket. Through the coupling energy of the two NFC induction coils, the receiving and conversion circuit of the mobile phone converts the current output from the NFC coil in the NFC communication module into DC power to charge the mobile phone battery.
[0040] To better understand this solution, wireless charging technology is described as follows:
[0041] Wireless charging technology includes three methods: electromagnetic induction, radio waves, and resonance. This application uses electromagnetic induction. Simply put, the current output from the output terminal is converted into high-frequency alternating current by a 2M active crystal oscillator inverter to supply the primary winding. The energy is coupled through two inductor coils (i.e., the NFC coil in the wireless charging bracket described in this application and the NFC coil in the NFC communication module of the mobile phone). The current output from the secondary coil (i.e., the NFC coil in the NFC communication module of the mobile phone) is converted into direct current by the receiving circuit to charge the mobile phone battery.
[0042] To better understand this solution, NFC communication technology is described as follows:
[0043] NFC (Near Field Communication) is a contactless identification and interconnection technology jointly developed by Philips and Sony. Operating at a frequency of 13.56MHz, it integrates RFID and interconnection technologies, offering low cost, ease of use, and intuitive connectivity. It enables short-range wireless communication between mobile devices, consumer electronics, PCs, and smart control tools. NFC provides a simple, touch-based solution for easier and more intuitive information exchange, access, and service interaction. NFC is a short-range, high-frequency radio technology operating at 13.56MHz within a 10cm range, with transmission speeds of 106Kbit / s, 212Kbit / s, or 424Kbit / s. NFC has been adopted as an international standard by ISO / IEC IS 18092, ECMA-340, and ETSI TS 102190. NFC includes both active and passive reading modes.
[0044] Preferably, it further includes:
[0045] Turn on the electric vehicle power, connect the mobile phone with the NFC communication module to the electric vehicle via Bluetooth, read the NFC ID number of the mobile phone, send the NFC ID number of the mobile phone to the mobile phone via Bluetooth, the user adds the NFC ID number to the electric vehicle whitelist on the mobile phone, and sends the electric vehicle whitelist to the electric vehicle processor via Bluetooth, and the electric vehicle processor stores the electric vehicle whitelist.
[0046] Understandably, when using the above solution, it is necessary to register the NFC ID number in advance. This means that when purchasing an electric vehicle, the owner needs to install the smart APP function. The owner connects to the vehicle's Bluetooth communication function through the mobile APP, places the phone on the wireless charging holder, and the vehicle's NFC function unit can immediately read the owner's mobile phone's NFC ID number. The vehicle processor transmits the NFC ID device number of the owner's mobile phone to the mobile APP via Bluetooth communication. The owner registers their mobile phone's NFC ID device number as a valid whitelist in the vehicle through the APP. The vehicle processor stores the successfully registered NFC ID number in the memory and queries the NFC ID number through the whitelist.
[0047] Preferably,
[0048] The NFC coil in the NFC communication module of the mobile phone and the NFC coil in the wireless charging bracket use multi-frequency antennas, and the frequency bands for wireless charging and NFC communication are set respectively.
[0049] The wireless charging frequency band of the NFC coil in the NFC communication module of the mobile phone is the same as the wireless charging frequency band of the NFC coil in the wireless charging stand.
[0050] The NFC communication frequency band of the NFC coil in the NFC communication module of the mobile phone is the same as the NFC communication frequency band of the NFC coil in the wireless charging bracket.
[0051] It is understandable that both wireless charging and NFC communication functions rely on two antennas (coils), but they operate on different frequency bands. This allows the wireless charging unit and the NFC communication unit to use a single antenna (coil) for multi-frequency time-division application. This design can save both cost and space.
[0052] Preferably, it further includes:
[0053] Once the wireless charging function of an electric vehicle is activated, the charging status will be displayed on the electric vehicle's dashboard via the vehicle's 485 communication module.
[0054] Understandably, once the user successfully starts the electric vehicle's power supply via their mobile phone and begins charging the phone, the electric vehicle's processor displays the charging status on the electric vehicle's dashboard through its own 485 communication module. In other words, the user can check on the dashboard whether charging has been successful.
[0055] Preferably,
[0056] The electric vehicle whitelist includes multiple NFC ID numbers;
[0057] It is understandable that the NFC communication module of the electric vehicle acts as the master device, and the NFC on the mobile phone acts as the slave device. One NFC master device can be configured with multiple slave devices, so that multiple users can start the electric vehicle through their mobile phones, thus improving the practicality of this application.
[0058] Example 2
[0059] This embodiment also discloses a system schematic diagram of a wireless charging and identification device for electric vehicles, as shown in the attached diagram. Figure 2 As shown, it includes:
[0060] NFC communication connection module 1: used to place a mobile phone with an NFC communication module on the wireless charging bracket of an electric vehicle. The wireless charging bracket is equipped with an NFC coil to realize NFC communication between the mobile phone and the processor of the electric vehicle.
[0061] NFC ID Query Module 2: Used to obtain the NFC ID number of the mobile phone and query the NFC ID number in the whitelist;
[0062] Wireless charging start-up module 3: If the NFC ID number of the mobile phone can be found in the whitelist, start the electric vehicle power supply and simultaneously start the wireless charging function of the electric vehicle. Charge the mobile phone by coupling the NFC coil in the wireless charging bracket with the NFC coil of the mobile phone's NFC communication module.
[0063] Understandably, this embodiment uses the NFC communication connection module 1 to place a mobile phone with an NFC communication module on the wireless charging bracket of the electric vehicle. The wireless charging bracket contains an NFC coil to enable NFC communication between the mobile phone and the electric vehicle's processor. The NFC ID query module 2 is used to obtain the mobile phone's NFC ID number and search for the NFC ID number in the whitelist. The wireless charging start module 3 is used to start the electric vehicle's power supply and simultaneously start the electric vehicle's wireless charging function if the mobile phone's NFC ID number can be found in the whitelist. The mobile phone is charged through the coupling between the NFC coil in the wireless charging bracket and the NFC coil of the mobile phone's NFC communication module. This embodiment does not require a key to open or close the electric vehicle, which can effectively improve the service life of the electric vehicle's key interface. At the same time, when the electric vehicle's power supply is turned on, the wireless charging function is activated. The purpose of wireless charging for the mobile phone is achieved through the coupling of two NFC coils of the same frequency band. This also solves the problems of insufficient mobile phone battery caused by continuous use of mobile phones by delivery and logistics electric vehicle owners, and the reduced service life of mobile phone charging interfaces caused by the need to constantly plug and unplug charging cables.
