The invention discloses a wireless charging device and system for electric vehicles, belonging to the technical field of wireless charging for electric vehicles, comprising: a transmitting coil for providing electric energy for the vehicle to be charged; two position measuring coils for receiving the energy generated by the vehicle to be charged Induce the magnetic field and excite the induced voltage, and transmit the induced voltage signal to the control module; the wireless communication module is used to receive the vehicle information of the car to be charged; the control module is used to receive the induced voltage signal, and calculate the transmission coil and The positional relationship between the receiving coils in the car to be charged sends the moving command to the mobile device; the mobile device is used to drive the charging device to turn after receiving the moving command so that the receiving coil of the car to be charged is aligned with the transmitting coil of the charging device, and Used to drive the charging device to move to the car to be charged. The invention reduces the size of the device and simplifies the system by installing two position measuring auxiliary coils on the wireless charging device.
Description
technical field [0001] The invention belongs to the technical field of wireless charging for electric vehicles, and more particularly relates to a wireless charging device and system for electric vehicles. Background technique [0002] In recent years, various technologies of commercial electric vehicles have gradually matured, and battery capacity and battery life have been further improved, which puts forward higher requirements for the power and safety of electric vehicle charging technology. In the traditional conductive charging method, the conductive point of the car is exposed to the outside, and there are potential safety hazards for users during operation. Moreover, charging requires frequent plugging and unplugging of the charging interface, which will cause wear and tear on the interface, affect the reliability of the contact, and may cause arcing, which is not safe for equipment and users. Due to its non-contact design, wireless charging can be completely insula...
