Acquiring accumulated time for detecting the overcurrent of the target fuse by using the loop to be detected;

when the accumulated time reaches a preset time threshold, determining that the overcurrent detection for the target fuse is completed, and disconnecting the target fuse from the peripheral circuit and the load box;

And carrying out numerical value updating treatment on the loop number to be detected to obtain an updated loop number to be detected, wherein the numerical value of the updated loop number to be detected is larger than that of the loop number to be detected, and the difference value is one.

In the embodiment of the overcurrent testing method provided by the application, the corresponding target fuse is determined through the current loop number to be tested, the loop number to be tested is updated after the detection of the target fuse is completed, and the updated loop number to be tested is applied to the determination of the corresponding fuse to be tested, so that the purpose of automatically switching the testing loop is realized.
