Abstract
The invention provides a detection system and detection circuit for detecting health status of backup power supply module. The detection circuit comprises a boost converter, a controller, and at least one backup power supply module. The boost converter receives an input voltage to generate a first high voltage. When the detection circuit is operated in a detection state, the boost converter is inhibited to output the first high voltage, the backup power supply module can execute a discharging process to provide a discharged energy to a load device, the controller detects a time at which a discharged potential of the backup power supply module is dropped from a first voltage to a second voltage to obtain a discharged time detection value. The controller can know a health status of the backup power supply module by a comparison between the discharged time detection value and a discharged time threshold value.
