    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.

    摘要： An electrical storage system includes an electrical storage device (10); a relay (SMR-B, SMR-G, SMR-P) switching between on/off states; a current interruption circuit (60) interrupting energization of the electrical storage device by causing the relay to switch from the on state to the off state; and a controller (30) executing drive control over the relay. The current interruption circuit includes an alarm circuit (63) outputting an alarm signal indicating overcharging/overdischarging of any one electrical storage block 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 the on state to the off state upon reception of an output signal of the latch circuit. The controller determines an energization state of the electrical storage device by executing control for turning on the relay while control for causing the alarm circuit to output the alarm signal is being executed.

    摘要： An alternating current impedance-estimating section (106) estimates an alternating current impedance (Rh) of the secondary battery based on electric current (I) and voltage (V) of the secondary battery detected when a ripple generating section causes a ripple current to flow in the secondary battery. A temperature estimating section (108) estimates the temperature (T) of the secondary battery based on the alternating current impedance (Rh) estimated by the alternating current impedance-estimating section (106) with the use of the relation, obtained in advance, between the temperature (T) of the secondary battery and the alternating current impedance (Rh) of the secondary battery at a ripple frequency.
