Description

technical field [0001] The invention belongs to the technical field of automobile electrical appliances, and in particular relates to a vehicle-mounted wireless charger with near-field communication and a method thereof. Background technique [0002] At present, wireless charging technology has been partially applied in the smart phone and wearable market, but the overall application penetration rate is not high. In the field of automotive electronics, wireless chargers mostly exist in the form of a closed system, which is only used to support wireless charging of mobile phones, and has no interaction with other on-board controllers of the vehicle. Charging technology is often regarded as weak in the field of vehicle applications, and OEMs are not willing to develop and install it, which further restricts the popularization of wireless charging technology and market development prospects. [0003] Near Field Communication (NFC) is a short-range high-frequency wireless commu...
