Method and device for preventing adapter or mobile power supply from being powered off in charging process

Abstract

The embodiment of the invention discloses a method for preventing an adapter or a mobile power supply from being powered off in a charging process. The method comprises the following steps: obtaining a charging voltage, and carrying out constant-current charging when the charging voltage is smaller than or equal to a first voltage threshold; periodically detecting the charging voltage in the constant-current charging process; and lifting the constant-current charging current to a first preset value when detecting that the charging voltage is greater than or equal to a second voltage threshold. The embodiment of the invention further correspondingly discloses a device for preventing the adapter or the mobile power supply from being powered off in the charging process. According to the method and the device for preventing the adapter or the mobile power supply from being powered off in the charging process, an overload phenomenon of a terminal along with rise of a battery voltage of a mobile phone in the charging process can be prevented; a charging power-off phenomenon caused by an overload is reduced; and the user experience is improved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for preventing an adapter or a mobile power supply from being disconnected during charging. Background technique [0002] Today's portable electronic devices, such as mobile phones, portable media players, notebook computers, tablet computers, etc., are usually powered by rechargeable batteries or directly from an outlet. Generally speaking, these portable electronic devices have matching power adapters, which are used to convert high-voltage alternating current into mortgaged direct current and provide them for use by electronic devices, so that electronic devices can work or charge at ideal preset voltage values , to prevent overloading caused by direct use of ordinary household electricity. [0003] In traditional technology, the quality of adapters / power banks on the market is uneven. In order to adapt to them, after the adapter is connected to the mobi...
