Abstract

A vehicle-mounted wireless charging system comprises a DC-DC power supply module and a wireless charging module, wherein the input end of the DC-DC power supply module is connected with a vehicle-mounted power supply, the output end of the DC-DC power supply module is connected with the wireless charging module, the vehicle-mounted wireless charging system also comprises a detection module and an input voltage regulation module, the detection module is used for detecting working frequency of the wireless charging module, the input voltage regulation module is used for regulating a power supply voltage provided by the DC-DC power supply module according to the detected working frequency, the detection module is connected with a feedback end of the wireless charging module, the input end of the input voltage regulation module is connected with the output end of the detection module, and the output end of the input voltage regulation module is connected with the DC-DC power supply module. In the vehicle-mounted wireless charging system, the detection module is used for detecting the working frequency of wireless charging module, the final output voltage of the DC-DC power supply module is controlled according to a regulation signal output from the voltage regulation module, the emission power of the vehicle-mounted wireless charging system is correspondingly changed with voltage change, thus, the frequency of a vehicle-mounted keyless system is avoided, and the interference is prevented.

Description

technical field [0001] The invention relates to the technical field of power supplies, belongs to a wireless charging system, and specifically refers to a vehicle-mounted wireless charging system. Background technique [0002] Established in 2008, the Wireless Power Consortium (WPC) is composed of many electronic component manufacturers and original equipment manufacturers from Asia, Europe and the Americas. WPC is committed to the global standardization of wireless charging technology, and the wireless charging standard "Qi" released by it makes wireless charging devices that comply with the standard compatible with each other. Any mobile terminal device that meets the "Qi" standard can be charged with a wireless charger that also meets the "Qi" standard, and can even support multiple mobile phones to charge at the same time. [0003] The main features of the "Qi" standard are: (1) Based on the principle of near-field electromagnetic induction of the coupling coil, the ene...
