Abstract

The invention discloses a charging method and device, computer equipment and a readable storage medium. The charging method comprises the following steps: if charging voltage of terminal equipment isdetermined not to be smaller than a set first voltage threshold value, reducing charging current of the terminal equipment according to set current stepping until the charging current of the terminalequipment is not greater than set constant charging current; charging the terminal equipment by using the constant charging current until the charging voltage of the terminal equipment is not smallerthan a set second voltage threshold value; and taking the second voltage threshold value as a new first voltage threshold value. Compared with the prior art, the charging method has the advantages that in an embodiment, when the charging voltage of the terminal equipment is not smaller than the set first voltage threshold value, charging current is not directly reduced to a small fixed current value, but the charging current is reduced step by step according to the set current stepping, therefore, large overall charging current can be ensured, the charging time is shortened, and the charging efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of charging, in particular to a charging method, device, computer equipment and a readable storage medium. Background technique [0002] At present, in order to shorten the charging time of terminal equipment and improve charging efficiency, the industry often uses double CV (Constant Voltage, constant voltage) points or multiple CV points to charge terminal equipment. For example, taking dual CV points as an example, in the first CC (Constant Current, constant current) stage, a constant charging current of 3A is used to charge the battery until the charging voltage of the battery exceeds the voltage threshold of the first CV point, such as 4.2 V, at this time, directly reduce the charging current of 3A to the constant charging current of the second CC stage, such as 2.1A, and use the constant current of 2.1A to charge the battery until the charging voltage of the battery exceeds the second CV point Voltage...
