PROBLEM TO BE SOLVED: To reduce a charge time by performing a charge in a power storage block having a plurality of power storage elements connected in parallel while confirming the operating state of a current limiter included in each power storage element.SOLUTION: A power storage system comprises: a power storage device (10) having a plurality of power storage blocks (11) connected in series; a voltage sensor (20) for detecting the voltage value of each power storage block; and a controller (40) for estimating the SOC of each power storage block on the basis of the detection result of the voltage sensor. The controller makes determination of a cut-off state while changing a total number of current limiters (12b) in a cut-off state from a large number side to a smaller number side according to a rise in the SOC of the power storage block after a charge of the power storage device has started. Each time the controller determines that the current limiters are not in a cut-off state, it raises a current value with which the power storage device is charged. |
