PROBLEM TO BE SOLVED: To precisely obtain a continuous voltage value as a power storage amount of a power storage device irrespective of a sampling cycle while monitoring the state of a power storage element of the power storage device constituted of a plurality of unit cells of the power storage elements. SOLUTION: This power storage system includes a means that detects a voltage of each unit cell of a power storage device and obtains a total voltage of the power storage device on the basis of the detected values so as to output it as a digital measured value Vdig, a means that outputs, as an analogue measured value "iana", a current flowing between the power storage device and a load connected thereto, a means that outputs a continuous voltage value Vhat as a total voltage of the power storage device by using a mathematic model on the basis of the analogue measured value "iana" of the current, and a means that calibrates the continuous voltage value Vhat by using the digital measured value Vdig of the voltage.
