Abstract

The invention discloses a method and terminal for determining the residual electric energy of a terminal in order to provide a solution for accurately calculating the residual electric energy of the terminal without a coulometer. The method comprises steps that the terminal calculates the internal resistance value of a battery when being powered on every time; the terminal detects the acquired present current value of the battery and determines a voltage compensation value according to the internal resistance value and the present current value of the battery, detects the acquired present voltage value of the battery and compensates the present voltage value of the battery with a voltage compensation value; and the terminal determines the residual electric energy of the battery according to the voltage value after compensation.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method for determining the remaining power of a terminal and a terminal. Background technique [0002] At present, terminals usually use hardware to calculate battery power, that is, use a power metering chip capable of calculating power to perform power calculation. [0003] In the prior art, the electricity metering chip is connected with the battery and the microprocessor through corresponding interfaces. When calculating the power, the power metering chip obtains the parameters such as the voltage value, current value and temperature of the battery through the corresponding interface, uses the preset discharge curve to calculate the real-time power, and outputs the current power to the microprocessor through the corresponding interface. The device will display the current power level to the user. [0004] However, the precision device such as the power mete...
