Title:

CHARGING APPARATUS AND TERMINAL

Document Type and Number:

WIPO Patent Application WO/2019/076012

Kind Code:

A1

Abstract:

Embodiments of the present application provide a charging apparatus and a terminal. The charging apparatus comprises a sampling module, a control module, a clamping module, and a switched capacitor module; wherein the sampling module is connected to the control module, and is used for connecting a battery, collecting current state information of the battery, and providing the collected state information to the control module; the control module is separately connected to the clamping module and the switched capacitor module, and is used for adjusting output energy of the clamping module according to the state information and providing a driving signal to the switched capacitor module; the clamping module is connected to the switched capacitor module, and is used for connecting a power supply, receiving power energy provided by the power supply, and processing the power energy into the output energy to be provided to the switched capacitor module; the switched capacitor module is used for connecting the battery, and providing charging energy to the battery according to the driving signal provided by the control module and the output energy provided by the clamping module. The charging apparatus is beneficial to improve the issue that the charging energy provided by a charging chip fluctuates with the power energy.
