Abstract

An electric storage apparatus (1) includes: a lithium-ion secondary cell (20); a battery voltage measuring unit (11) and a charging/discharging voltage measuring unit (12) for measuring a potential difference between two arbitrary points on a charging/discharging path; a current measuring unit (17) for measuring a current flowing on the charging/discharging path; a latch relay (30) disposed between the two points on the charging/discharging path; a switch controller (14) for driving the latch relay (30); and a drive determining unit (15) for determining the operational state of the latch relay (30) based on the control state of the switch controller (14) and at least one of the measurement result of the voltage measuring unit (11, 12) and the measurement result of the current measuring unit (17).
