Charging system and charging method thereof

Abstract

Disclosed is a charging system and a charging method thereof. The charging system is applicable for charging an electronic device by at least a charging device and includes a detecting module configured to detect a voltage of a power storage unit of the electronic device; and a control module. When the electronic device is in a turned-off state, the control module is configured to conduct charging the power storage unit by a first current of one of said at least a charging device, upon judging that the voltage is substantially lower than a first value, and the control module is also configured to conduct charging the power storage unit by a second current of one of said at least a charging device, upon judging that the voltage is substantially higher than or equal to the first value.

Dependencies are inferred from the claim text.
