Abstract

A charging method of a portable electronic device, adapted to charge a battery module of a portable electronic device, the charging method comprising detecting a battery voltage and a charging current of the battery module; determining whether the portable electronic device operates at a constant current mode according to the battery voltage; entering an over voltage protection charging loop while the portable electronic device operates at the constant current mode and allows the battery module to be charged up at a maximum charging voltage, and leaving the over voltage protection charging loop while the charging current is smaller than a predetermined current, wherein the maximum charging voltage is gradually decreased according to a comparison result between the battery voltage and an overcharging protection voltage; and setting the maximum charging voltage as a full charge voltage while leaving the over voltage protection charging loop.
