A terminal remaining power display method and device

Abstract

The embodiment of the invention discloses a remaining electricity quantity display method and a remaining electricity quantity display device for a terminal, relates to the field of communication, and is used for avoiding the problem that electricity quantity display is abnormal due to the fact that an electricity quantity measurement chip is damaged. In the embodiment of the invention, the remaining electricity quantity display method comprises the following steps of acquiring circuit parameters for characterizing the terminal battery electricity quantity change from the starting moment of a terminal to the current t moment, calculating a battery electricity quantity change value Q(t), and calculating the proportion SOCSW(t) of the battery remaining electricity quantity at the current t moment to full electricity quantity according to SOCSW0, Q(t) and QMAX; if the battery electricity quantity measurement chip in the terminal is initialized successfully, acquiring the proportion SOCIC(t) of the battery remaining electricity quantity output by the battery electricity quantity measurement chip at the current t moment to the full electricity quantity; according to SOCSW(t), judging whether SOCIC(t) is accurate or not, and if yes, displaying the remaining electricity quantity according to SOCIC(t) output by the battery capacity measurement chip; if not, displaying the remaining capacity according to the calculated SOCSW(t), and therefore the problems are solved.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a method and device for displaying remaining power of a terminal. Background technique [0002] Current 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 metering chip is easily dam...
