PROBLEM TO BE SOLVED: To solve the problem that, if a leakage current flows through an electrical element connected in parallel with a power storage block, a detected voltage value of the power storage block is different from an actual voltage value.SOLUTION: A power storage system includes: a plurality of power storage blocks including respective power storage elements (11) and connected in series; a voltage detection circuit (40) for detecting a voltage value of each power storage block via voltage detection lines (L1 and L2); electrical elements (D) connected in parallel with the respective power storage blocks via the voltage detection lines and capable of interrupting a current flow; and a controller (30) for specifying an open voltage value of each power storage block. If the open voltage value of a first power storage block is lower than a reference voltage value and the open voltage value of a second power storage block connected to an electrode terminal of the first power storage block is higher than the reference voltage value, the controller determines that the detected value of the first power storage block anomalously includes a voltage drop following a leakage current to the electrical element. |
