Abstract

The invention discloses a terminal capable of accurately obtaining battery voltage during charging and a method for obtaining battery voltage. The device includes: a charging interface, a battery, a resistor, and a power management module; the first end of the power management module is connected to the charging interface. The second end and the third end of the power management module are connected to one end of the resistor and the system module of the mobile terminal, and the fourth end of the power management module is connected to the other end of the resistor and the positive pole of the battery; the power management module is used to set the initial charging cut-off voltage; and when the battery is charging, obtain the voltage difference between the two ends of the resistor, and determine the voltage value of the battery according to the voltage difference. The invention can accurately obtain the actual voltage of the battery when the battery is charging, and then obtain the real power of the battery, and display it to the user, so that the user can know the power of the battery, and can also enable the terminal to accurately charge whether the battery is fully charged or not. , so that the charging of the battery is more stable and accurate.

Description

technical field [0001] The invention relates to electronic equipment, in particular to a terminal capable of accurately obtaining battery voltage during charging and a battery voltage obtaining method. Background technique [0002] In recent years, smart terminals such as mobile phones have developed rapidly, and have basically reached the state of one in everyone's hands. Since the development of smart terminals is moving towards smarter and larger screens, the CPU (central processing unit, central processing unit) of smart terminals needs to be faster in processing speed, so that it consumes more power. Existing smart terminals generally use large-capacity battery, so as to improve the battery life of the smart terminal. [0003] When the smart terminal is charging, it is often necessary to display the real-time power information of the battery, so that the smart terminal can judge whether it needs to continue charging, and feedback the real power of the battery to the us...
