Embodiment Construction
[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0026] The charging process of the battery is constant current charging first. When it reaches the limit voltage of the battery, it will switch to constant voltage charging. During constant voltage charging, the charging current will gradually decrease. When the charging current is less than the cut-off current, the charging will stop. During the charging process, the change of battery capacity is mainly in the constant current stage. Since the ...

The invention discloses a charging electric quantity calculation method and device. The method comprises the following steps: setting a plurality of comparison points; detecting whether battery percentage displayed at one comparison point deviates from a standard battery percentage curve; when the battery percentage displayed at the comparison point deviates from the standard battery percentage curve, setting a first reference point with the battery percentage being known, wherein charging time of the first reference point is larger than the charging time of the comparison point, and the first reference point is one point on the standard battery percentage curve; and adjusting the electric quantity displayed at any one point between the comparison point and the first reference point according to a straight line connecting the comparison point and the first reference point. Through the mode above, the method can optimize accurate display of battery percentage in the battery charging process, and thus user experience is improved.
Description
technical field [0001] The invention relates to the technical field of battery charging, in particular to a method and device for calculating charging power. Background technique [0002] In the current mobile phone power display, various errors will continue to accumulate due to various error reasons during the charging and discharging process of the mobile phone, resulting in a large difference between the displayed capacity and the actual capacity. If it is not corrected in time, it may cause The charging current is still much higher than the cut-off current, but the screen displays 100%, or directly displays 100% from more than 90%, and there is a sudden change in power, no matter which situation occurs, it will seriously affect the user experience. [0003] figure 1 It is an example in an actual test. The curve in the figure indicates the time it takes to increase the power by 1%. The following table represents the time spent in the last 4%: [0004] 96％-97％...
