[0031] Example 1
[0032] This application provides a wireless charging device, such as... Figure 1-2As shown, the device includes a mobile charging robot 11 and a wireless charging conversion module 12, with the mobile charging robot 11 connected to the wireless charging conversion module 12. The mobile charging robot 11 includes a wireless charging management module 111, a power transmission control module 112, and a magnetic field transmitting module 113. Both the magnetic field transmitting module 113 and the wireless charging management module 111 are connected to the power transmission control module 112. The wireless charging conversion module 12 includes a charging controller 121 and a magnetic field receiving module 122. The charging controller 121 is connected to the wireless charging management module 111, and the magnetic field receiving module 122 is connected to the magnetic field transmitting module 113.
[0033] The wireless charging management module 111 receives charging requests from the charging controller 121, initiates wireless charging, and sends a charging start command to the power transmission control module 112. The power transmission control module 112 executes the charging command and transmits power. The magnetic field transmitting module 113 acquires the transmitted power and generates an alternating electromagnetic field. The magnetic field receiving module 122 receives the alternating electromagnetic field generated by the magnetic field transmitting module 113 and converts the alternating electromagnetic field back into electrical energy for charging new energy vehicles. The charging controller 121 also acquires the charging status and demand of the vehicle battery during the charging process, dynamically adjusts the transmission power to avoid overcharging or undercharging, and when a metallic foreign object is detected near the charging area, it can change the frequency or power output by modulating the signal to prevent potential safety risks and improve charging safety.
[0034] In this embodiment, the magnetic field transmitting module 113 is the primary coil, and the corresponding magnetic field receiving module 122 is the secondary coil. Voltage conversion and transmission are achieved through electromagnetic induction. The connection between the primary and secondary coils is more precise, and the coil offset is basically 0, thereby improving the efficiency of wireless energy transmission.
[0035] In this embodiment, the wireless charging management module 111 includes a first communication module 1111, and the charging controller 121 includes a second communication module 1211. The first communication module 1111 and the second communication module 1211 are signal-connected to ensure effective information transmission between the wireless charging management module 111 and the charging controller 121. Preferably, both the first communication module 1111 and the second communication module 1211 are Bluetooth modules, which have the advantages of low power consumption, small size and light weight, high-speed transmission, and good stability.
[0036] In summary, the wireless charging device provided in this embodiment, with its magnetic field emitting module 113 installed inside the mobile robot, does not need to be laid on the ground. Each use only requires the device to be kept intact, thus preventing foreign objects from accumulating on the surface and eliminating the need for regular maintenance. The device is compact and easy to maintain, improving the success rate of wireless charging. Furthermore, when used with the mobile charging robot 11 in conjunction with new energy vehicles, the robot automatically arrives at any parking space and precisely connects with the vehicle via the wireless charging conversion module 12 for charging. This invention features a simple structure, low implementation cost, and easy maintenance.
[0037] Example 2
[0038] This application provides a charging system for new energy vehicles, such as... Figure 3 As shown, the system includes: the wireless charging device 1 as described above and a new energy vehicle 2, with the new energy vehicle 2 connected to the wireless charging device. Further, the new energy vehicle 2 includes: an on-board power controller 21 and an on-board battery management module 22; both the on-board power controller 21 and the on-board battery management module 22 are connected to the charging controller 121; the magnetic field receiving module 122 and the on-board battery management module 22 are both connected to the on-board power controller 21. The charging controller 121 receives charging battery information from the vehicle battery management module 22. The charging controller 121 sends a charging request to the wireless charging management module 111 via wireless communication. The wireless charging management module 111 checks whether the magnetic field transmitting module 113 and the magnetic field receiving module 122 have completed matching. If the matching is completed, the wireless charging management module 111 sends a charging start command. The wireless charging management module 111 and the charging controller 121 forward data information from the power transmission control module 112, the charging controller 121, and the vehicle battery management module 22, maintaining real-time communication and exchanging information such as battery status and power requirements to ensure that both parties work synchronously, thereby improving charging efficiency and charging safety.
