Charging state monitoring device, terminal and method

Abstract

The invention provides a charging state monitoring device, comprises a switch monitoring module and a state judging module, wherein the switch monitoring module is used for monitoring the state of a circuit charging switch connected with a battery inside a terminal; and the state judging module is used for determining the battery to be in a negative charging state when the circuit charging switch is in an on state and determining the battery to be in a charging state when the circuit charging switch is an off state. Correspondingly, the invention further provides the terminal and a charging state monitoring method. By means of the technical scheme provided by the invention, a user can be informed of the true charging state of the terminal, and a proper suggestion can be provided to make the user adopt a correct measure so as to optimize the charging state of the terminal and shorten the charging time.

Description

technical field [0001] The present invention relates to state monitoring technology, in particular to a charging state monitoring device, a terminal and a charging state monitoring method. Background technique [0002] At present, with the increasing popularity of smart phone terminals with rich functions and numerous application software, the charging problem of mobile phone terminals has become more and more troublesome for users. Although the correct charging method is to turn off the power to charge, most users will not do this, because if the power is turned off, in addition to missing important calls, it may not be possible to pass the boring time. The vast majority of users use charging while making calls or listening to MP3, watching movies, browsing the web, and transferring files via Bluetooth. [0003] However, the above method may cause the problem of slow charging, zero charging, or even negative charging of the mobile terminal, but the user does not know this....

Problems solved by technology

[0003] However, the above method may cause the problem of slow charging, zero charging, or even negative charging of the mobile terminal, but the user does not know this. That is to say, although the mobile terminal will start to display the charging icon after plugging in the charger, whether the battery The real charging status, charging speed, and the time required to complete charging are not displayed, and ordinary users cannot know it at all.

[0004] Under the existing technical solutions, the above problems can be alleviated by increasing the input current of the charger, but now more and more mobile phones start to use USB charging, and the standard USB requires that the current cannot exceed 500mA, that is, when the power consumption of the mobile phone terminal exceeds At this threshold, the battery of the mobile terminal is not actually charged, and even provides power for the mobile terminal instead.
