Problems solved by technology

Similarly, during the charging process of the battery, if it encounters the influence of too low temperature, it will cause the normal performance of the electrolyte inside the battery to fail and affect the charging state. High and low temperature detection can avoid the above battery problems
In addition, it will damage the battery or directly cause the battery to explode during over-current charging.

Abstract

The invention provides a method and device for detecting the battery charging state of a terminal device. The method comprises: detecting whether to start the charging of the terminal device, and if so, acquiring the charging state information of the battery of the terminal device; acquiring the temperature data of the battery in real time by using a voltameter and sending the temperature data to a master control module for analysis and judgment; determining that the battery is in a normal charging state when the master control module detects that the temperature data is within a preset safety section; stopping charging the battery when a first preset condition is satisfied; switching off the terminal device when a second preset condition is satisfied; and recharging the battery when a third preset condition is satisfied. The method stops charging the battery, restarts charging the battery, and switching off the terminal device according to the different conditions satisfied by the temperature data, and adjusts the control state according to the change of the temperature data, thereby ensuring the safety of the charging.

Description

technical field [0001] The invention relates to the technical field of mobile terminal and battery detection, in particular to a method and a detection device for detecting the charging state of a battery of a terminal device. Background technique [0002] A few days ago, battery safety issues such as mobile phone charging explosions swept the major news headlines, and people's attention to the safety of mobile phone rechargeable batteries has risen to a new level. Similarly, this problem not only exists in mobile phone equipment, but also exists in terminal electronic equipment using batteries. Traditional equipment does not detect the battery status when the battery is charging, or the detection method is not comprehensive and intelligent enough, or even has problems such as false status reporting, which leads to overcharging and overheating of the battery, causing the battery to heat up, leak or even explode. [0003] The batteries used in most electronic devices today a...
