Abstract
An energy storage apparatus includes: an external terminal connected to an energy storage device; a current cut-off device disposed on a current path connecting the energy storage device and the external terminal to each other; a voltage applying circuit that applies a voltage to the external terminal using the energy storage device or another circuit as a power source; and a control device. The control device is configured to perform: current cut-off processing for cutting off flowing of a current into the energy storage device by bringing the current cut-off device into an OPEN state; detecting processing for detecting a voltage of the external terminal to which a voltage is applied by the voltage applying circuit during a period in which the flowing of the current is cut off by the current cut-off processing; and determining processing for determining a presence or a non-presence of a short-circuiting object.
