An energy storage apparatus includes: an energy storage device; a voltage dropper configured to drop a charge voltage for the energy storage device; a current switcher connected in parallel with the voltage dropper; a voltage detection unit configured to detect a voltage of the energy storage device; and a controller. When the voltage of the energy storage device exceeds a predetermined value, the controller causes the current switcher to switch a path of a charge current to the energy storage device to a path through the voltage dropper.
