Abstract

The invention is suitable for the technical field of electric quantity calibration, and provides a battery electric quantity determination method and device, terminal equipment and a storage medium, and the method comprises the steps: obtaining a first calibration voltage of a battery at an (i-1) th sampling moment when it is determined that a battery voltage value before an ith sampling moment suddenly changes, the first calibration voltage is determined based on the j-n-th voltage variation of the battery in the j-n-th sampling period and the j-th voltage variation of the battery in the j-n-th sampling period, and the j-th sampling period is a sampling period in which the voltage variation is smaller than a preset threshold value for the first time after the j-n-th sampling period; obtaining a second calibration voltage based on the first calibration voltage and the jth voltage variation; determining the battery electric quantity at the ith sampling moment based on the second calibration voltage; voltage jitter is eliminated, the battery electric quantity is determined more accurately, and the battery electric quantity changes stably.

Description

technical field [0001] The present application belongs to the technical field of power calibration, and in particular, relates to a method, device, terminal device and storage medium for determining the power of a battery. Background technique [0002] The power of the battery is a parameter for the user to know the battery usage. At present, the battery power measured by the coulomb fuel gauge is relatively accurate, but due to the high cost of the coulomb fuel gauge, in order to save costs, many electronic devices are not equipped with a coulomb fuel gauge. In electronic devices without a coulomb fuel gauge, the voltage of the battery is often used to estimate the battery power. When the voltage is high, the battery power is high, and when the voltage is low, the battery power is low. However, the voltage of the battery is prone to fluctuations. For example, when the electronic device is connected to the adapter, the voltage of the battery will suddenly rise, or when the ...
