摘要
A charging device including a charging circuit, a voltage detection circuit, and a keyboard controller is provided. The charging circuit receives a charging power source, and produces a battery-charging power source at a first node by the charging power source to charge a battery. The voltage detection circuit detects a voltage at the first node, and produces a voltage detection result. The keyboard controller determines whether the voltage at the first node is less than a predetermined voltage according to the voltage detection result, and determines whether a predetermined condition has been satisfied, wherein the predetermined condition includes the voltage at the first node being less than the predetermined voltage, and the keyboard controller is arranged to force the charging circuit to stop producing the battery-charging power source at the first node when the predetermined condition has been satisfied.
