Executing method and device for calibrating a coulomb counter

Abstract

Embodiments of the present invention provide an execution method and device for calibrating a coulomb counter, which relate to mobile terminal development technology. When it is determined that a charger is connected to the mobile terminal and the coulomb counter needs to be calibrated, start the power supply of the charger to the mobile terminal, stop the power supply of the battery to the mobile terminal and the charging of the battery by the charger, so that the inflow and outflow of the battery The currents are all zero, and the conditions for calibrating the coulomb meter are reached, and the coulomb meter is calibrated. The execution method for calibrating the coulomb counter provided by the embodiment of the present invention can meet the conditions for calibrating the coulomb counter when the user charges the mobile terminal, and can realize timely calibration of the coulomb counter.

Description

technical field [0001] The present invention relates to mobile terminal development technology, in particular to an execution method and device for calibrating a coulomb counter Background technique [0002] The coulomb counter is an intelligent instrument for DC power measurement and control. It is installed inside the mobile terminal, either on the main board of the mobile terminal or in the battery of the mobile terminal. The coulomb counter is used to cumulatively monitor the working ampere hours and working volt hours of the DC power of the mobile terminal battery, so as to grasp the consumption of the main components of the solution in the battery and the thickness of the coating in the battery in a timely manner, and according to the set ampere-hour cycle Automatically control the work of the metering pump and the volt-hour cycle to realize the addition of solution components. [0003] Due to the drift characteristic of the coulomb counter, there will be an error whe...

Problems solved by technology

[0013] The disadvantages of this technical solution are: some application software of the mobile terminal will often wake up the mobile terminal automatically, and the mobile terminal itself may also perform network search operations, which cannot maintain the standby state, resulting in a sudden change in current, which cannot reach the mobile terminal’s calibration of the coulomb counter. conditions that prevent the calibration of the coulomb counter

[0014] In summary, none of these three technical solutions can realize the calibration of the coulomb counter in time
