Abstract: An energy storage apparatus for a moving body includes: an energy storage cell; an external terminal for connecting the energy storage apparatus to the moving body; a current interruption device provided to a connection line that connects the energy storage cell and the external terminal, the current interruption device being configured to interrupt a current of the energy storage cell; a first parallel circuit connected in parallel to the current interruption device and the energy storage cell; and a control unit, wherein the first parallel circuit includes a resistor and a switch that is connected to the resistor in series, and the control unit is configured to determine, in a state where the current interruption device is switched to an open state and the switch of the first parallel circuit is switched to a closed state, an electrical connection state of the energy storage apparatus to the moving body based on a current that flows from the moving body via the external terminal and the first parallel circuit.
