A load access detection method, a switch circuit, and a battery management system, relating to the field of circuit technology. The load access detection method includes: detecting a voltage at a first detection point; detecting a voltage at a second detection point; if a voltage difference between the voltage at the first detection point and the voltage at the second detection point is less than or equal to a preset voltage threshold, controlling a switch circuit to enter a pre-charging mode, and pre-charging a load capacitor in the load circuit through the battery pack, where a charging current of the switch circuit in the pre-charging mode is less than a charging current of the switch circuit in a charging mode.
