More Information
Summary:A method and device for displaying SOC of a battery, and electronic equipment are provided. The method includes: an initial voltage and initial SOC of the battery are acquired (101); a current voltage and current SOC of the battery in a current state are acquired after charging or discharging the battery for a preset time (102); and if the ratio of the current voltage to the initial voltage meets a first preset condition and the ratio of the current SOC to the initial SOC meets a second preset condition, the current voltage and the current SOC are displayed (103). The SOC of the battery is obtained according to a corresponding relationship of voltage and SOC changes of the battery in charging and discharging processes of the battery, so that accurate calculation of the SOC of the battery is implemented without an additional hardware circuit such as a voltameter chip, the valuable Printed Circuit Board (PCB) arrangement space in terminal equipment is saved, cost is further reduced, and a degree of freedom of hardware design and competitiveness of a product are increased.
