Abstract
Embodiments of the present invention provide a charging protection method, including: measuring a charging voltage, a charging current, and a temperature rise of a charging interface of a charged device; detecting whether the charging voltage falls beyond a preset voltage range, detecting whether the charging current is less than a preset current threshold, and detecting whether the temperature rise is greater than a preset temperature rise threshold; and if a detection result of any one or more of the three items is yes, disconnecting a charging circuit of a charger. Correspondingly, the embodiments of the present invention further provide a charging protection apparatus, which can disconnect a charging circuit in a timely manner when a charging exception occurs, thereby avoiding damage to a charging interface.
