Charging system and electronic equipment

Abstract

The embodiment of the invention discloses a charging system and electronic equipment. The charging system comprises first electronic equipment and second electronic equipment; the first electronic equipment comprises a transmitting coil; the second electronic equipment comprises a receiving coil; when the receiving coil of the second electronic equipment is close to the transmitting coil of the first electronic equipment, the first electronic equipment transmits electric energy to the second electronic equipment; when the charging power while the first electronic equipment transmits the electric energy to the second electronic equipment is less than a pre-set power threshold value, the second electronic equipment sends a charging power increasing signal to the first electronic equipment; after the first electronic equipment receives the charging power increasing signal, the number of turns of the transmitting coil is changed; or, the charging voltage is boosted; and thus, the chargingpower when the first electronic equipment transmits the electric energy to the second electronic equipment is increased. By adoption of the embodiment of the invention, the charging efficiency of wireless reverse charging can be increased; therefore, the user experience of a reverse charging technology is good; and the applicability is high.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a charging system and electronic equipment. Background technique [0002] With the continuous development of mobile Internet technologies, user equipment (user equipment, UE) such as mobile phones, tablet computers or notebook computers has become one of the indispensable items in people's work and life. Thanks to the continuous improvement of people's user experience on user equipment, wireless charging technology, which is different from traditional wired charging, has emerged as the times require. Because the wireless charging technology can make the charging process of the user equipment no longer need to consider the limitation of the data line, which is convenient for the user. Therefore, wireless charging technology has also become one of the current research hotspots. [0003] The current wireless charging technology mainly includes a forward charging mode and a rev...

AI Technical Summary

Problems solved by technology

In the prior art, the charging power provided by the user equipment in the reverse charging mode is relatively low, generally kept at about 2.5W, which obviously cannot meet the charging requirements of the user equipment in the forward charging mode

This leads to low charging efficiency of the current wireless reverse charging technology and poor user experience
