The invention provides a charging current control method and system, electronic equipment and a storage medium, and the method comprises the steps: obtaining a charging demand current value of a vehicle end based on the sum of a maximum allowable charging current value of a vehicle-mounted battery and a current consumed by a high-voltage accessory; calculating a charging current value based on the charging demand current value, the maximum allowable charging current value of the pile end and the national standard fast charging current limiting value; obtaining a corresponding charging current coefficient based on the charging port temperature value obtained in real time; and obtaining an actual charging current value according to the charging current value and the charging current coefficient, and charging the vehicle-mounted battery based on the actual charging current value. The charging demand current value of the vehicle end is calculated, then the charging current value of the pile end is calculated, the charging coefficient is calculated according to the temperature value of the charging port, and the vehicle-mounted battery is charged according to the charging current value and the charging current coefficient, so that the current fault of mismatched response of the vehicle end and the pile end caused by charging current adjustment is reduced; the charging efficiency is improved, and the charging time is shortened.
