The invention relates to an electric charge equalizing system and method for batteries for making the equalization speed of the capacitor to be quickly charged in advance possible which the advantage of the switch-capacitor converter is brought out. The equalization speed of the conventional technology which was indicated as one of the disadvantages has been eased by increasing the speed, and the extension and charge of the battery life, as well as the efficiency of the battery all have been increased, so that the battery stability of the discharge can be guaranteed by equalizing the electric charge of the multiple battery unit cells that are serially connected to each other. The battery cell electric charge equality system according to the present invention includes a charge battery part, a sensing part, a capacitor portion, and a controlling element that determine the overcharging or over discharge as the voltage value of the charge battery part which the sensing part measures and the switch which multiple capacitors respectively switches the unit cell of the corresponding two among multiple unit cells including multiple capacitors are serially connected. And each unit cell is connected to the second unit cell that is adjacent to the first unit cell for the second time by the secondary connection state of the switch, and it is connected and charged in the multiple capacitors of the first unit cell among the multiple unit cells for the first duration by the first concatenated state of the switch controlling element when the controlling element is determined to be either fully charged or over discharged.
