Title:
SHORT-CIRCUIT FAULT HANDLING APPARATUS AND METHOD
Document Type and Number:
WIPO Patent Application WO/2018/152993
Kind Code:
A1
Abstract:
A short-circuit fault handling apparatus and method. The short-circuit fault handling apparatus comprises a short-circuit fault handling circuit which may comprise: an input power supply, a driving power supply, a control module, a detection module, and a fault handling module; when detecting the access of a terminal device to be charged, the detection module sends a signal to the control module; when receiving the signal sent by the detection module, the control module connects a power input end of the terminal device to the driving power supply, and triggers the detection module to detect a path signal; the control module connects the power input end of the terminal device to the input power supply when the detection module detects that the path signal is normal, or sends a trigger signal to the fault handling module when the detection module detects that the path signal is abnormal, in order to trigger the fault handling module to handle a short-circuit fault. By using the short-circuit fault handling apparatus and method, an abnormal short-circuit fault at a charging interface of the terminal device can be handled in time, and the service life of the charging interface can be prolonged.
