According to an embodiment of the present invention, a secondary battery system comprises: a secondary battery; a first measurement unit for measuring a volume change of the secondary battery; a designation unit for designating a threshold value; and a control unit for controlling a current flowing the secondary battery based on the threshold value and the volume change of the secondary battery measured by the first measurement unit. The secondary battery reduces a charging time while reducing the deterioration of the secondary battery.
