Embodiment Construction

[0029] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0030] In the traditional technology, the open circuit voltage method or charge accumulation method is generally used to detect the remaining battery power. However, based on the open circuit voltage method to detect the remaining power of the battery, only the open circuit voltage of the battery is considered during the detection process, while the method based on the charge accumulation method to detect the remaining power of the battery only considers the output current of the battery during the detection process. The dimension of factors considered in the detection pro...

Abstract

The invention relates to a battery remaining capacity detection method and device, electronic equipment and a storage medium. The method comprises the following steps: acquiring an accumulated consumed electric energy value of a battery of the electronic equipment from a discharge starting moment to a target moment; and acquiring a full-charge electric energy value of the battery, and taking a difference value between the full-charge electric energy value and the accumulated consumed electric energy value as a residual electric energy value of the battery at the target moment, wherein the residual electric energy value is positively correlated with the residual electric quantity of the battery at the target moment. The method can improve the detection accuracy of the residual electric quantity of the battery.

Description

technical field [0001] The present application relates to the technical field of batteries, in particular to a method, device, electronic equipment and storage medium for detecting the remaining battery power. Background technique [0002] With the popularization of electronic devices, various electronic devices appear in people's daily life. As a power supply component of electronic equipment, batteries are an indispensable part of electronic equipment. The remaining power of the battery is an important parameter describing the state of use of the battery, and can provide power data reference for users or electronic devices. [0003] At present, the open circuit voltage method or charge accumulation method is generally used to detect the remaining battery power. The open-circuit voltage method is to detect the open-circuit voltage of the battery, and look up the table to obtain the remaining battery power corresponding to the open-circuit voltage; the charge accumulation ...
