The embodiment of the invention discloses a charging current control method and device, electronic equipment and a storage medium. The method comprises the following steps: acquiring a first cell voltage value of a battery pack; determining whether the first battery cell voltage value is located in a voltage platform area in a preset closed circuit voltage (CCV)-residual electric quantity (SOC) curve of the battery pack or not; wherein the voltage change amplitude of the closed-circuit voltage in the voltage platform area is smaller than a preset amplitude threshold value; in response to the situation that the first battery cell voltage value is located in the voltage platform area, determining a target voltage of the voltage platform area based on the change trend of the battery cell voltage value of the battery pack and the first battery cell voltage value; and determining the charging current of the battery pack in the voltage platform area based on the target voltage. Through the scheme, the accuracy of the voltage value of the first battery cell of the battery pack can be improved, and then the precision of the charging current control method of the electronic equipment is improved.
