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

摘要

A circuit protection method. The method comprises: receiving a voltage or a current sent by a sending end and sampling a received voltage value or a received current value; when it is detected that the sampled voltage value or current value is in a first preset threshold range, controlling a preset input control switch to be on, and receiving the input of a voltage or a current of the sending end; performing conversion processing on the received voltage or current, and sampling a voltage value of the processed voltage or a current value of the processed current; and when it is detected that the processed voltage value or current value is in a preset second threshold range, controlling a preset output control switch to be on, and allowing the processed voltage or current to be output. Also disclosed are a circuit protection apparatus, a charging device, and a computer storage medium.
