Problems solved by technology

[0002] With the complexity of mobile terminal systems, there are more and more cases of system abnormalities (such as crashes), and many terminal devices cannot be restarted after long pressing the power button, because the system is already in an abnormal operating state, and the only way to restart The method is to disconnect the battery and reconnect the battery to power on. For some mobile terminals with detachable batteries, users can manually disassemble and reinstall them, which is cumbersome to operate. For mobile terminals with non-detachable batteries (such as mobile phones and tablets), once the If the system is abnormal (such as crash), the mobile terminal will not be able to boot all the time

Abstract

Disclosed are a battery protection circuit (100), a battery (200) and a mobile terminal (300), wherein the battery protection circuit (100) comprises: a voltage collection circuit, wherein a first end of the voltage collection circuit is connected with a positive pole of a battery body (202), a second end of the voltage collection circuit is connected with a negative pole of the battery body (202), and the voltage collection circuit is used for collecting voltage information about the battery body (202); a current collection circuit, wherein a first end of the current collection circuit is connected with a negative pole of the battery body (202), a second end of the current collection circuit is connected with a first regulation device, and the current collection circuit is used for collecting discharging current information of the battery body (202); and a first control module (102) respectively connected with the voltage collection circuit, the current collection circuit and the first control device, wherein the first control module (102) is used for controlling the first regulation device so same is in a conducting or cut-off state according to the voltage information about the battery body (202) and the discharging current information about the battery body (202).

Description

technical field [0001] The present invention relates to the technical field of circuits, in particular, to a battery protection circuit, a battery and a mobile terminal. Background technique [0002] With the complexity of mobile terminal systems, there are more and more system abnormalities (such as crashes), and many terminal devices cannot be restarted after long pressing the power button, because the system is already in an abnormal operating state, and the only way to restart The method is to disconnect the battery and reconnect the battery to power on. For some mobile terminals with detachable batteries, users can manually disassemble and reinstall them, which is cumbersome to operate. For mobile terminals with non-detachable batteries (such as mobile phones and tablets), once the If the system is abnormal (such as crash), then the mobile terminal will always be unable to start. [0003] Therefore, how to realize the restart of the mobile terminal without disassemblin...
