Method and system for preventing charging voltage of intelligent terminal from being increased

Abstract

The invention discloses a method and a system for preventing a charging voltage of an intelligent terminal from being increased. The method comprises the steps of sending a voltage reduction instruction to a power supply management module through a central processing unit when a charging voltage detection module detects that the electric quantity percentage of a lithium battery at the intelligent terminal is greater than or equal to 98%, and finally controlling the voltage of the lithium battery to be reduced to a stable range through the power supply management module to be output. By adoption of the method provided by the invention, the voltage of the lithium battery at the intelligent terminal can be effectively prevented from being increased in a charging process; and it is ensured that the voltage of the lithium battery is reduced to the stable and normal range to be output, so that the internal device of the intelligent terminal is effectively protected, and the service life of the lithium battery is prolonged.

Description

technical field [0001] The invention relates to the field of mobile terminal charging, in particular to a method and system for preventing the charging voltage of an intelligent terminal from being pulled up. Background technique [0002] Generally, when the existing smart terminal is in the charging process or after the charging is completed, when the charger is unplugged, the voltage of the lithium battery of the smart terminal will be pulled up, and the charging circuit of the lithium battery needs to be turned on instantly. The high voltage output of the battery not only easily damages the internal devices of the smart terminal, but also reduces the service life of the lithium battery. [0003] Therefore, the prior art still needs to be improved and developed. Contents of the invention [0004] In view of the deficiencies in the prior art above, the purpose of the present invention is to provide a method and system for preventing the charging voltage of the smart term...
