Abstract

An embodiment of the invention discloses a rechargeable battery and a charging circuit thereof. The charging circuit comprises: a power supply input unit and a charging management unit, wherein a first direct current is generated by the power supply input unit according to a working power output by a power supply, and the charging management unit pre-charges or charges a battery cell according toa difference between a first voltage value of the first direct current and a second voltage value of the battery cell, so that the process of charging the rechargeable battery is simpler.

Description

Technical field [0001] The invention belongs to the field of electronic technology, and particularly relates to a rechargeable battery and a charging circuit thereof. Background technique [0002] Many existing electronic products are equipped with rechargeable batteries that can be repeatedly charged and used, such as terminals and smart wearable devices. [0003] Although the existing rechargeable battery combined with its peripheral control circuit can achieve overcharge or overdischarge protection, when charging the rechargeable battery in the prior art, the charging circuit first detects whether the cell is in the overdischarge protection state, if so, Then the charging circuit outputs the corresponding pre-charging current to pre-charge the battery cell, until the charging circuit detects that the battery cell is not in an over-discharged state, it outputs the charging current to charge the battery cell. Therefore, when charging the rechargeable battery in the prior art, it ...
