Abstract
A charging circuit and a charging method of a battery are disclosed. The charging circuit provides a charging current to charge the battery. The charging circuit includes a charging control module, a current detecting module and a compensation module. The charging control module provides a charging voltage. The current detecting module detects the charging current, and generates a detecting voltage according to the charging current. The compensation module detects the charging voltage, and provides a feedback voltage to the charging control module according to the detecting voltage and the charging voltage.
