Abstract

The embodiment of the invention discloses a protection method for a charging interface, and is applied to a terminal. The charging interface of the terminal comprises a first power line and a first loop line, a voltage sampling module and a current source are arranged between the first power line and the first loop line, a first conduction module is arranged on the first power line, and the methodcomprises the following steps of acquiring a charging detection instruction; responding to the charging detection instruction, sending a detection control signal to a power adapter, controlling the first conduction module to be disconnected, and controlling the first power line, the current source and the first loop line to be conducted to form a charging detection loop; detecting impedance corresponding to the first power line on the charging detection loop through the voltage sampling module to obtain voltage drop information; when the voltage drop information is not larger than a preset voltage drop value, starting charging; and when the voltage drop information is larger than the preset voltage drop finger, the charging is not started. The embodiment of the invention also discloses aprotection system for the charging interface and a storage medium.

Description

technical field [0001] The invention relates to charging technology in the field of electronic technology, in particular to a method and system for protecting a charging interface, and a storage medium. Background technique [0002] Existing terminals mostly use chargers for charging, so as to recycle the terminals in an environment-friendly situation. The charger is a charging device composed of a power adapter and a charging cable, and the terminal is connected to the power adapter through the charging cable. When the power adapter is connected to an external power supply, the voltage adapter converts the input AC voltage of the external power supply into a DC voltage, and transmits the DC voltage to the terminal through the charging cable to complete charging of the terminal. However, the charging interface of most terminals is generally exposed to the outside, and the pins of the exposed charging interface will be dirty, corroded and oxidized after a long time, especial...
