Zusammenfassung:The invention discloses a circuit and method for detecting existence of a battery on a charger. The circuit for detecting the existence of the battery on the charger comprises a signal generator and a signal detector and is characterized in that the signal generator is connected with an output end of the charger, and a signal for detection is applied to the output end. The signal detector is connected with the output end and detects the output end, and then judges whether the battery exists or not according to a detected signal. The circuit for detecting the existence of the battery on the charger has the advantages of being simple in detection method and clear in detection result.
