Charging protection method and apparatus

A charging protection apparatus, comprising a voltage detector, a current detector, a temperature detector, and a charging manager, wherein

• the voltage detector is connected to a charging interface of a device, and the voltage detector is configured to detect whether a charging voltage of the charging interface belongs to a preset voltage range when a charger and the device are connected;
• the current detector is connected to the charging interface of the device, and the current detector is configured to detect whether a charging current is less than a preset current threshold when the charger and the device are connected;
• the temperature detector is connected to a temperature sensor located near the charging interface, and the temperature detector is configured to obtain a temperature measured by the temperature sensor, and detect whether the temperature rise is greater than a preset temperature rise threshold;
• and
• the charging manager is connected to the voltage detector, the current detector, and the temperature detector, and is configured to disconnect a charging circuit of the charger when at least one of the following conditions is met:
• the charging voltage is not in the preset voltage range;
• the charging current is less than the preset current threshold;
• or
• the temperature rise is greater than the preset temperature rise threshold.

An electronic device, comprising a charging protection apparatus and a charging interface, wherein the charging protection apparatus is configured to:

• measure a charging voltage, and a temperature rise of the charging interface of the electrical device when a charger and the electronic device are connected;
• detect whether the charging voltage is in a preset voltage range;
• detect whether the temperature rise is greater than a preset temperature rise threshold;
• and
• disconnect a charging circuit of the charger when at least one of the following conditions is met:
• the charging voltage is not belong to a preset voltage range;
• or
• the temperature rise is greater than a preset temperature rise threshold.
