Abstract: A monitoring apparatus for an energy storage device provided at a movable body and electrically connected to a load of the movable body via a switch, includes a monitoring unit supplied with power from the energy storage device. The monitoring unit executes monitoring operation of bringing the switch from a closed state into an opened state under a condition that the energy storage device has voltage not more than a discharge voltage threshold, and bringing the switch from the opened state into the closed state under a condition that the switch is in the opened state and the energy storage device satisfies a predetermined discharge recovery condition, and decreases power consumption by extending an interval of the monitoring operation when the load is under suspension while the switch is in the opened state, in comparison to a case where the load is in operation.
