Abstract

The invention discloses an NFC-based wireless charging apparatus applied to a wireless charger. The wireless charger is provided with a first NFC module, a charging circuit and an antenna connected with the charging circuit; the wireless charging apparatus comprises a transmitting module and a first control module, wherein the transmitting module is used for transmitting preset voltage information to to-be-charged equipment through the first NFC module when the to-be-charged equipment is detected; and the first control module is used for controlling the charging circuit, based on a charging voltage, to transmit a first electromagnetic signal through the antenna when the charging voltage received through the first NFC module is less than or equal to a first preset voltage. The invention also discloses an NFC-based wireless charging method. By adoption of the NFC-based wireless charging method and apparatus, low-voltage direct charging of the to-be-charged equipment is realized, so that heating of the to-be-charged equipment in a heating process can be reduced by relatively low charging voltage, energy loss in the charging process is lowered, and the charging efficiency of the to-be-charged equipment is improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a wireless charging method and device based on NFC communication. Background technique [0002] Currently, there are three wireless charging standards: Power Matters Alliance (PMA) standard, Qi standard, and Alliance for Wireless Power (A4WP) standard. Among them, the Qi standard and the A4WP standard are relatively widely used. The Qi standard is the first standardization organization in the world to promote wireless charging technology - the "Wireless Charging" standard launched by the Wireless Power Consortium (WPC). It has two characteristics of convenience and versatility. As long as there is a Qi logo, Both can be charged with Qi standard wireless chargers; however, Qi standard wireless chargers can only charge Qi-labeled devices, and only one device can be charged at a time. The A4WP standard wireless charger focuses on the introduction of "electromagnetic...
