Abstract: [Problem] To provide a configuration for cutting off energization of an electricity storage block without interposing a controller.[Solution] The electricity storage system has: an electricity storage block including an electricity storage element (11) for performing charging and discharging; a relay (SMR-B, SMR-G) switched between an ON state in which the electric storage block is connected to a load (22, 23) and an OFF state in which a connection between the electricity storage block and the load is cut off; a controller (34) for controlling the ON state and the OFF state of the relay; and a current cutoff circuit (60) for switching the relay from the ON state to the OFF state, so as to cut off energization of the electricity storage block. The current cutoff circuit has: an alarm circuit (CMP, 62, 63) for outputting an alarm signal indicating that the electricity storage block is in an overcharged state by comparing a voltage value of the electricity storage block and a threshold; a latch circuit (64) for retaining the alarm signal; and a transistor (68) for receiving an output signal of the latch circuit and switching the relay from the ON state to the OFF state.
