Problems solved by technology

However, due to its small capacity, it cannot be used for a long time
And the electronic equipment has the minimum power that can be started, if the battery power is lower than the minimum power, it cannot drive the electronic equipment to run
Therefore, there needs to be a way to detect the power of the battery, and replace the battery before the battery is exhausted, otherwise it is easy to have an embarrassing moment when the electronic device cannot be driven due to insufficient power.
Existing, usually use V-C curve adopting constant resistance, constant current discharge to measure the capacity of dry batteries produced in the same batch, and the voltage-battery remaining capacity curve (hereinafter referred to as V-C curve) in the discharge process to detect the battery remaining capacity, but There may be large errors in the process of obtaining the V-C curve, and it is difficult to ensure the consistency of the V-C curve, which leads to errors in the detection of the remaining capacity of the battery.

Abstract

The invention discloses a battery power capacity detection method applied to an electrical device with a battery. The method comprises: detecting a current working state of an electrical device; calculating a power capacity state value of the current working state of the electrical device according to the current working state; determining whether the calculated power capacity state value changes;if so, calculating an effective power capacity of the battery. The effective power capacity of the battery is the battery power capacity keeping the minimum operating voltage of the electrical device. In addition, the invention also discloses an electronic device and a storage medium. When the working state of the electrical device changes, all power capacity states values that are in positive correlation with the effective power capacity of the battery in working states are calculated and iterative operation is performed to obtain the effective power capacity of the battery. Therefore, whether the power capacity of the battery can maintain the normal operation of the electrical device is monitored in real time.

Description

technical field [0001] The invention relates to the field of electronic energy storage, in particular to a method for detecting battery power, electronic equipment and a storage medium. Background technique [0002] At present, batteries have become the choice of energy supply for more and more electronic devices because of their convenience and compactness. But because of its small capacity, it cannot be used for a long time. Moreover, the electronic equipment has a minimum power that can be activated. If the power of the battery is lower than the minimum power, the electronic equipment cannot be driven to run. Therefore, it is necessary to have a method to detect the power of the battery, and replace the battery before the battery is exhausted, otherwise it is easy to cause an embarrassing moment when the electronic device cannot be driven due to insufficient power. Existing, usually use V-C curve adopting constant resistance, constant current discharge to measure the ca...
