Abstract

The invention provides a constant current charging device which is used for charging a to-be-charged device and comprises a reference current source for providing a reference current; a current mirror which is electrically coupled to the reference current source and outputs a mirror current; a current adjusting unit which is electrically coupled to the current mirror and the to-be-charged device and outputs a charging current according to the mirror current so as to charge the to-be-charged device; and a current compensation unit which is electrically coupled to the current mirror and the current adjusting unit and adjusts the charging current according to the reference voltage.

Description

technical field [0001] The disclosure relates to the technical field of charging, in particular to a constant current charging device. Background technique [0002] Existing charging devices include a constant current charging mode and a constant voltage charging mode. When the battery is initially charged, the charging device charges the battery in a constant current charging mode. After the battery is charged to a certain voltage, the charging device charges the battery in a constant voltage charging mode. [0003] However, the current and voltage provided by the existing charging device are sometimes unstable, and the unstable current or voltage will not only affect the charging efficiency of the battery, but also reduce the service life of the battery. [0004] Therefore, it is necessary to propose a solution to the above-mentioned problems in the prior art. Contents of the invention [0005] The disclosure provides a constant current charging device, which can solv...
