Abstract

The invention provides a battery charging control method, device, storage medium and electronic equipment. The method includes: acquiring real-time charging parameters of the battery, the charging parameters at least including one of the following: voltage, capacity and current; detecting whether the real-time charging parameters are in the Predetermined parameter range; in the case of the predetermined parameter range, the charging voltage of the battery is adjusted to a first voltage, so as to charge the battery according to the first voltage, wherein the first voltage is a charging limit voltage increased by a predetermined ratio. The real input voltage of the battery in the embodiment of the present invention is also the voltage after the predetermined ratio is increased according to the charging limit voltage, and the increased part of the voltage can offset some voltage drop caused by the impedance of the charging line, and by prolonging the charging time of the battery in CC mode, at the same time Improve charging efficiency, reduce battery charging time, and improve user experience.

Description

technical field [0001] The invention relates to the field of control, in particular to a battery charging control method, device, storage medium and electronic equipment. Background technique [0002] Under the current system design, the EC (embedded controller) of the system directly reads the charging voltage and charging current required for battery charging during charging, and writes the corresponding register of the charger to realize charging. [0003] According to the actual charging curve of the battery, when the real voltage of the battery does not reach the charge voltage (charging limit voltage), it will switch from CC mode to CV mode, which affects the battery charging efficiency and prolongs the battery charging time. [0004] The root cause of the above phenomenon is that the impedance of the charging line has a certain voltage drop, the output voltage of the charger is divided by the charging line, the real voltage of the battery is lower than the charging li...

[0003] According to the actual charging curve of the battery, when the real voltage of the battery does not reach the charge voltage (charging limit voltage), it will switch from CC mode to CV mode, which affects the battery charging efficiency and prolongs the battery charging time.

[0004] The root cause of the above phenomenon is that the impedance of the charging line has a certain voltage drop, the output voltage of the charger is divided by the charging line, the real voltage of the battery is lower than the charging limit voltage, and the battery switches from CC mode (constant current charging mode) to CV prematurely. mode (constant voltage charging mode), which reduces the charging efficiency
