Document Type and Number:
WIPO Patent Application WO/2023/197817
Kind Code:
A1
Abstract:
Provided in the embodiments of the present application are a charging circuit and a charging apparatus. The charging circuit comprises a charging power supply, a first switch, and a control unit, wherein the charging power supply comprises at least one programmable constant voltage source; the first switch is connected between the charging power supply and a battery; the control unit is separately connected to the charging power supply and the first switch; and the control unit obtains, according to a target charging current, a first control voltage for controlling the first switch or a second control voltage for controlling the programmable constant voltage source, so as to control the magnitude of a charging current. Therefore, constant-current charging of the programmable constant voltage source may be realized.
