Problems solved by technology

When the user uses wired charging for the electronic device, it is necessary to connect the charging adapter and the electronic device to be charged through the charging cable. Once the charging cable is missing, the electronic device cannot be charged.
However, although wireless charging has the advantage of not requiring a charging cable, based on the existing wireless charging scheme, due to the limitation of the wireless charging receiving coil and the requirements of the integrated circuit process, not only the improvement of charging power is limited, but also the charging efficiency is relatively low. Low

Embodiment Construction

[0035] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. It should be understood that the specific embodiments described here are only used to explain the related application, not to limit the application. It should also be noted that, for the convenience of description, only the parts related to the relevant application are shown in the drawings.

[0036] Wireless charging technology originates from wireless power transmission technology. According to different wireless charging principles, wireless charging methods are mainly divided into three types: electromagnetic induction (or magnetic coupling), radio wave and electromagnetic resonance. At present, mainstream wireless charging standards include Qi standard, Power Matters Alliance (PMA) standard and Alliance for Wireless Power (A4WP), etc. Among them, both Qi standard and PMA ...

Abstract

The embodiment of the invention discloses to-be-charged equipment, a to-be-charged system, a wireless charging method and a storage medium. The to-be-charged equipment comprises a receiving coil, a first charging unit and a second charging unit, wherein the receiving coil comprises a first end, a second end and a center tap; the first charging unit is respectively connected with the first end and the center tap and is used for converting the electromagnetic signals received by the first end of the receiving coil and the center tap into first voltage and first current for battery charging; and the second charging unit is respectively connected with the second end and the center tap and is used for converting the electromagnetic signals received by the second end of the receiving coil and the center tap into second voltage and second current for charging the battery.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and in particular to a device to be charged, a system, a wireless charging method, and a storage medium. Background technique [0002] At present, the commonly used charging methods for electronic devices such as smartphones, PDAs, notebooks and charging treasures include wired charging and wireless charging. When the user adopts wired charging for the electronic device, it is necessary to connect the charging adapter and the electronic device to be charged through the charging cable. Once the charging cable is missing, the electronic device cannot be charged. However, although wireless charging has the advantage of not requiring a charging cable, based on the existing wireless charging scheme, due to the limitation of the wireless charging receiving coil and the requirements of the integrated circuit process, not only the improvement of charging power is limited, but als...
