Abstract
Provided are a load detection system and a load detection method thereof. The load detection system includes an adjustable power supply (110) and a detection module (12). The adjustable power supply (110) and a to-be-detected load 120 together form a set load detection circuit (11), and the adjustable power supply (110) is configured to output a changing power supply signal to the to-be-detected load (120) through the set load detection circuit (11). The detection module (12) is configured to detect at least two changing electrical parameters in the set load detection circuit (11), acquire an equivalent resistance value of the to-be-detected load (120) according to the at least two changing electrical parameters, and detect whether the to-be-detected load (120) includes a charging device according to a non-linear change curve or a linear change curve formed by the equivalent resistance value and the power supply signal.
