In the process of monitoring the cell internal resistance and/or cell voltage of the battery of the mobile terminal, the mobile terminal can determine the battery usage safety level based on the monitored change value, wherein the battery usage safety level can be used to identify Whether the monitored battery can be used safely, for example, can be used to identify whether abnormal discharge, spontaneous combustion, explosion and other dangerous situations will occur when the battery is continued to be used.

The abnormality of the mobile terminal battery is usually caused by the internal short circuit of the battery cell, and when the internal short circuit of the battery cell occurs, it will quickly cause changes in the internal resistance of the cell and the voltage of the cell. Therefore, according to the battery cell The change value of the internal resistance of the cell and/or the cell voltage can quickly determine the safety level of the battery.

It can be seen from the above that the embodiments of the present invention can first monitor the cell internal resistance and/or cell voltage change value of the battery of the mobile terminal, and then, based on the monitored cell internal resistance and/or cell voltage, can The change value of the battery to determine the safety level of the mobile terminal battery.
