Abstract: Provided is an estimation device for estimating an actual capacity of an energy storage device or a total reduction amount of the actual capacity. The estimation device includes a processor which is configured to calculate the actual capacity of the energy storage device or the total reduction amount of the actual capacity based on approximation data where a capacity change curve indicative of a transition of the actual capacity or a transition of the total reduction amount of the actual capacity with respect to an elapsed time is approximated by a plurality of straight lines.

Abstract: An energy storage apparatus includes: an energy storage device; and a first spacer and a second spacer that sandwich the energy storage device. The first spacer includes: a first body portion facing the energy storage device; a first wall portion protruding from the first body portion toward the second spacer along the energy storage device; and a first protruding portion protruding from the first wall portion. The second spacer includes: a second body portion acing the energy storage device; a second wall portion protruding from the second body portion toward the first wall portion along the energy storage device; and a second protruding portion protruding from the second wall portion. The first protruding portion includes a spaced-apart portion where a distance between the first protruding portion and the second protruding portion is larger than a distance between the first wall portion and the second wall portion.

Abstract: A battery monitoring unit includes a control IC, a CPU, and a load circuit. In the inside of the battery monitoring unit, the control IC and the CPU each of which is a control circuit are connected to a unit internal ground that is common thereto. The load circuit is connected to a power ground different from the unit internal ground. In the inside of the battery monitoring unit, the power ground and the unit internal ground are connected with each other via a diode. The unit internal ground and the power ground are connected to an external ground that is common thereto via an electric wire extending from a first ground terminal and an electric wire extending from a second ground terminal, respectively.
