Abstract

Provided in the present invention is a charging management method for a charging circuit. The charging circuit comprises a supply terminal and a charging terminal. A charging process of the charging circuit comprises a plurality of cycles, each cycle comprising one charging suspension stage and one charging operation stage. The charging management method comprises: S1. acquiring a voltage of the charging terminal at the charging suspension stage; S2. determining a charging scheme according to the voltage of the charging terminal, wherein the charging scheme comprises a trickle charging scheme, a constant-current charging scheme, a constant-voltage charging scheme, and a charging suspension scheme; and S3. performing the charging scheme at the charging operation stage. Also provided in the present invention is a charging circuit capable of implementing the charging management method described above. By providing a charging suspension stage to acquire a voltage of a charging terminal during the charging process, the present invention can accurately reflect the charging state of the charging terminal, so as to avoid selecting an inappropriate charging scheme due to an inaccurate voltage value which would affect the service life of a battery.

Description

technical field [0001] The invention relates to the technical field of charging, in particular to a charging management method for a charging circuit and a charging circuit. Background technique [0002] At present, the charging process of the battery is generally divided into four stages: a trickle charging stage, a constant current charging stage, a constant voltage charging stage and a charging termination stage. The trickle charge stage usually refers to the stage of restorative charging for a fully discharged battery, that is, the battery is charged with a small current; the constant current charge stage is achieved by increasing the charging current after the trickle charge stage is completed. The stage of rapid charging; when the voltage of the battery rises to near saturation, the constant voltage charging stage starts, that is, the charging current is reduced to a smaller value to realize the stage of charging the battery; when the voltage of the battery reaches sat...
