摘要： Each of the electric storage elements has a current interrupt device interrupting a current path within the electric storage element. The controller uses the voltage detected by the voltage sensor to calculate the estimated value of a current passing through the electric storage block having a plurality of electric storage elements connected in parallel. The controller uses the correspondence between a first ratio and a second ratio to determine whether or not the current interrupt device is in an interrupt state. The first ratio is the ratio between the estimated current value and the reference value of a current passing through the electric storage block. The second ratio is the ratio between the total number of the electric storage elements constituting the electric storage block and the total number of the current interrupt devices not in the interrupt state.

摘要： An electrical storage system includes: an electrical storage device (10) including serially connected electrical storage blocks; a relay (SMR-B, SMR-G) switching a connection state between the electrical storage device and a load; a controller (30, 34) controlling the relay; and a current interruption circuit (60) interrupting energization of the electrical storage device. The current interruption circuit (60) includes an alarm circuit (63) outputting an alarm signal indicating that any one electrical storage block is overcharged or overdischarged by comparing a voltage value of each electrical storage block with a threshold; a latch circuit (64) retaining the alarm signal; and a transistor (68) causing the relay to switch from an on state to an off state upon reception of a latch circuit output signal. The controller determines an energization state of the electrical storage device after executing control for causing the alarm circuit to output the alarm signal by changing the voltage value or the threshold.
