Abstract

The invention discloses an electric quantity calculation method and device, a storage medium and electronic equipment. The electric quantity calculation method is applied to the electronic equipment, the electronic equipment comprises a battery, and the electric quantity calculation method comprises the following steps: when the battery starts to be charged, obtaining a first residual capacity of the battery; when the battery is fully charged, obtaining the first charging capacity of the battery, wherein the first charging capacity is the capacity charged into the battery in the process of starting to charge the battery until the battery is fully charged; calculating a first full charge capacity of the battery according to the first residual capacity and the first charge capacity; and calculating the residual electric quantity of the battery according to the first full charge capacity. In the scheme of the invention, the actual fully-charged capacity of the battery is used as the reference to calculate the residual electric quantity, and the method is not influenced by the increase of the internal resistance, and can accurately calculate the residual electric quantity.

Description

technical field [0001] The present application belongs to the technical field of battery charging and discharging, and in particular relates to a power calculation method, device, storage medium and electronic equipment. Background technique [0002] When a new battery is first put into use, the electronic device's calculation of the remaining power is accurate. However, after repeated charging and discharging for many times, the battery will age, so the power will decrease rapidly after the battery is fully charged, or the actual power will be lower than the remaining power displayed by the electronic device, resulting in sudden shutdown and so on. This is because the increase in internal resistance of the battery after aging affects the calculation of the remaining power. If the battery is still in use at this time, that is, without considering the increase in the internal resistance of the battery to calculate the remaining power, the actual power will be less than The c...
