Wireless mobile power pack circuit and charging method

Abstract

The invention relates to a wireless mobile power pack circuit and a charging method, and belongs to the mobile device charging. A wireless charging receiving slice is connected with a mobile phone through a mobile phone USB interface. The wireless charging receiving slice is adhered on the shell of a mobile power pack. When an alternating current passes through coils of an inductor CL1, an inductor CL2 and an inductor CL3, magnetic induction lines changing along with time appear around the coils. Induction electromotive force is generated at two ends of the coils by the changing magnetic induction lines. The induction electromotive force is equivalent to a new power supply. When the coil of a receiving device is located in the ranges of magnetic induction lines changing along with the time, the induction electromotive force is produced at two ends of the coils through electromagnetic induction, thus generating a current. The power supply is supplied to the mobile phone through the receiving slice of the mobile phone or by using the wireless charging receiving slice. When the circuit is used, it is unnecessary to plug in and pull out a charging plug repeatedly; and a charger is avoided from being damaged due to frequent plug-in and pull-out. The circuit and the method are safe and convenient in use and have a function of flexible usage of wireless charging and wire changing.

Description

technical field [0001] The invention relates to a mobile wireless charging treasure circuit and a charging method, which are used for charging mobile devices. Background technique [0002] The current mobile charging equipment (power bank) can directly charge mobile equipment, and has its own power storage unit. At present, the main categories of multi-functional charging treasures in the market are basically equipped with standard USB output, which can basically meet the needs of mobile devices that are common in the current market, such as mobile phones, MP3, MP4, PDA, PSP, Bluetooth headsets, digital cameras and other digital products. Charge. In daily life, work, and leisure, the power consumption of smart phones is relatively large, and power needs to be replenished at any time. Because the traditional wired charging mode requires repeated plugging and unplugging of the charging plug during use, it is easy to cause damage to the interface, resulting in failure. Charge...

Problems solved by technology

In daily life, work, and leisure, the power consumption of smart phones is relatively large, and power needs to be replenished at any time. Because the traditional wired charging mode requires repeated plugging and unplugging of the charging plug during use, it is easy to cause damage to the interface, resulting in failure. Charge

In modern society, the number of people with two mobile phones is gradually increasing, and the mode of only charging one mobile phone cannot meet the actual needs of today's users.
