LOAD DETECTION SYSTEM AND LOAD DETECTION METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2020/181739
Kind Code:
A1
Abstract:
Provided are a load detection system and a load detection method thereof, wherein the load detection system comprises an adjustable power supply (110) and a detection module (12), the adjustable power supply (110) and a load to be detected (120) form a set load detection circuit (11), the adjustable power supply (110) is set to output a changed power signal to the load to be detected (120) through the set load detection circuit (11), the detection module (12) is set to detect at least two changed electrical parameters in the set load detection circuit (11), and to detect whether the load to be detected (120) contains a charging device according to a non-linear change curve or a linear change curve formed by an equivalent resistance value and the power supply signal.
