Fault detection method for grounding system, equipment and storage medium

The invention discloses a fault detection method for a grounding system, equipment, a storage medium and a device. The method comprises the steps of: obtaining all load input current values in the grounding system and first total current values of all grounding points; judging the faults in the grounding points according to the load input current values and the first total current values; and disconnecting one grounding point from a vehicle body, obtaining a second total current value set of the other grounding points, and judging the fault between the grounding points according to the first total current values and the second total current value set, thereby realizing the comprehensive detection of the faults of the grounding system. In the prior art, comprehensive fault detection of thegrounding system cannot be realized, however, according to the embodiment of the invention, the faults in the grounding points are detected firstly, and then the faults between the grounding points are detected, so that compr
