CIRCUIT PROTECTION METHOD AND APPARATUS, CHARGING DEVICE, AND COMPUTER STORAGE MEDIUM

摘要

The present disclosure discloses a circuit protection method. The method includes that: a voltage or a current sent by a sending end is received, and a received voltage value or current value is sampled; when it is detected that the sampled voltage value or current value is in a first pre-set threshold range, a pre-set input control switch is controlled to be turned on, and the input of a voltage or a current of the sending end is received; the received voltage or current is converted, and a voltage value of the processed voltage or a current value of the processed current is sampled; and when it is detected that the processed voltage value or current value is in a second pre-set threshold range, a pre-set output control switch is controlled to be turned on, and the processed voltage or current is allowed to be outputted. The present disclosure also discloses a circuit protection apparatus, a charging device and a computer storage medium.
