Electric leakage detection method and device, and terminal equipment

The embodiment of the invention discloses an electric leakage detection method and device, and terminal equipment, and is applied in the technical field of mobile communication. According to the embodiment of the invention, the method comprises the steps: detecting whether the terminal equipment is connected with a charger or not; monitoring the voltage of a corresponding pin of a charging interface of the terminal equipment if the terminal equipment is connected with the charger; judging whether the voltage of the corresponding pin of the charging interface exceeds a preset voltage threshold value or not; controlling the terminal equipment to be disconnected with the charger if the voltage of the corresponding pin of the charging interface exceeds the preset voltage threshold value, and controlling the terminal equipment to output and alarm prompt signal. According to the embodiment of the invention, the method can remind a user of high-voltage electric leakage, and reduces the safety hidden troubles. 本发明实施例
