The invention discloses a state-of-charge correction method, device and equipment and a storage medium, and the method comprises the steps: when a charging gun is detected to be inserted into a charging port, if a battery is detected to enter a charging preparation state and the duration when the current is smaller than a preset current threshold value is greater than a preset first duration threshold value; obtaining a battery voltage and searching a corresponding target charge state; calculating a difference value between the target charge state and the estimated charge state to obtain a charge state difference value; if the charge state difference value is larger than a first difference value threshold value, the pre-estimated charge state is corrected to be the sum of the target charge state and the first charge state adjusting quantity, so that the charging safety of the battery can be guaranteed, and if the charge state difference value is smaller than a second difference value threshold value, the pre-estimated charge state is corrected to be the sum of the target charge state and the second charge state adjusting quantity, so that the charging safety of the battery can be guaranteed. The battery charging speed can be improved; according to the first difference threshold value, the two state-of-charge adjusting variables are larger than 0, and the second difference threshold value is smaller than 0. The second state-of-charge adjusting quantity is smaller than the absolute value of the state-of-charge difference value.
