Problems solved by technology

Due to the low power of wireless charging, if the power is increased, the wireless charging will cause serious heating, which will pose a threat to the safety of the charging circuit and the battery. Once the wireless charging causes serious heating of the circuit and damages the charging circuit, it will cause damage to the entire charging circuit.

Abstract

An embodiment of the present application provides a charging circuit and an electronic device. The electronic device includes a battery, the battery includes a first charging terminal and a second charging terminal, and the charging circuit includes a wired charging circuit and a wireless charging circuit. The input end of the wired charging circuit is used for connecting the output end of the wired charger, the output end of the wired charging circuit is connected with the first charging terminal, and the output end of the wireless charging circuit is connected with the second charging terminal. The embodiment of that present application may improve charging efficiency.

Description

technical field [0001] The present application relates to the field of electronic technology, in particular to a charging circuit and electronic equipment. Background technique [0002] With the development of electronic technology, wireless charging technology has gradually been applied to terminals, such as terminals containing batteries such as mobile phones, tablet computers, or remote control devices. Since the terminal does not need to be connected to a power source through a cable during the wireless charging process, the wireless charger can be used to charge the terminal at different locations. Wireless charging and wired charging generally charge the battery separately, and charge the same terminal of the battery during the actual charging process. Due to the low power of wireless charging, if the power is increased, the wireless charging will cause serious heating, which will pose a threat to the safety of the charging circuit and the battery. Once the wireless c...
