Abstract

The invention relates to a battery remaining capacity estimation method and device, electronic equipment and a computer readable storage medium, and the method comprises the steps: obtaining the real-time open-circuit voltage of a battery, and obtaining the real-time discharge depth corresponding to the real-time open-circuit voltage from the corresponding relation between the open-circuit voltageof the battery and the discharge depth according to the real-time open-circuit voltage; obtaining the real-time residual electric quantity of the battery according to the real-time discharge depth, wherein the open-circuit voltage is obtained in real time, so that the accuracy of the obtained open-circuit voltage is greatly improved. The corresponding relation between the open-circuit voltage andthe discharge depth of the battery is calculated in advance, then the real-time discharge depth corresponding to the real-time open-circuit voltage can be directly searched for from the correspondingrelation after the real-time open-circuit voltage of the battery is acquired, and then the real-time residual electric quantity of the battery can be obtained according to the real-time discharge depth. Therefore, smooth change of the residual electric quantity of the battery is realized, and abnormal conditions such as tripping are reduced.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a method and device for estimating remaining battery power, electronic equipment, and a computer-readable storage medium. Background technique [0002] With the popularization and wide application of electronic equipment, people's daily life is increasingly inseparable from electronic equipment, and the frequency of use of electronic equipment is also increasing. As an important component for powering electronic equipment, batteries are extremely important. The remaining battery capacity (State of Charge, SOC) is an important parameter describing the current state of the battery and plays an important role in the field of battery management. The traditional method of estimating the remaining battery power cannot accurately estimate the remaining battery power, so that it often happens that the power display quickly jumps when the battery is low or the remaining batte...
