Problems solved by technology
[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

The invention provides a battery charging control method and device, a storage medium and electronic equipment, and the method comprises the steps: obtaining real-time charging parameters of a battery, wherein the charging parameters at least comprise one of selected from the voltage, capacity and current; detecting whether the real-time charging parameter is within a preset parameter range or not; and under the condition of being within the preset parameter range, adjusting the charging voltage of the battery to be a first voltage so as to charge the battery according to the first voltage, wherein the first voltage is the charging limiting voltage obtained after the preset proportion is increased. According to the embodiment of the invention, the real input voltage of the battery is the voltage obtained after the preset proportion is increased according to the charging limiting voltage, the increased part of voltage can counteract some voltage drops caused by the impedance of the charging circuit, and the charging efficiency is improved, the charging time of the battery is shortened, and the user experience is improved.
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...
