Abstract
A power adapter comprises a power conversion unit, a charging interface, an anomaly detection unit, and an anomaly handing unit. The power conversion unit forms a charging loop with a terminal via the charging interface, so as to charge a battery of the terminal. The anomaly detection unit detects whether an anomaly occurs on the charging loop. When the anomaly occurs on the charging loop, the anomaly handing unit controls the charging loop to enter into a protection state. The power adapter can improve the security of a charging process. Also provided are a terminal, and a method for handing an anomaly in a charging loop.
