    Abstract: A state estimation device includes: a voltage detecting unit that detects voltages of energy storage devices; and an estimating unit that estimates a charge amount difference between at least two of the energy storage devices. At a reference time point T0 during constant current charging, the estimating unit performs: specific voltage setting for setting, as a specific voltage V0, a voltage of a low-voltage energy storage device at the reference time point T0; time obtaining for obtaining a time point at which a voltage of a high-voltage energy storage device reaches the specific voltage V0; and charge amount difference estimating for estimating the charge amount difference between the at least two energy storage devices based on the reference time point T0, the time point obtained in the time obtaining process, and a current flowing through the plurality of energy storage devices during the constant current charging.

    Abstract: Provided is a power source module which includes: a plurality of energy storage devices stacked in a stacking direction; end plates sandwiching the plurality of energy storage devices therebetween; and a plurality of fastening bars connecting the end plates to each other; wherein the energy storage device includes: a terminal surface on which an electrode terminal is mounted; a bottom surface; and first and second side surfaces. Each of the fastening bars includes an extending portion extending parallel to the stacking direction and fastening portions extending parallel to the end plates. As viewed in the stacking direction, a total area of the fastening portions positioned in a region close to the terminal surface with respect to a center line between the terminal surface and the bottom surface is set larger than a total area of the fastening portions positioned in a region close to the bottom surface with respect to the center line.

    Abstract: An energy storage apparatus includes: an outer case formed of a body, and a lid body which covers an opening of the body; an energy storage device which is accommodated in the outer case; and a handle which is mounted on the lid body. The lid body has a first surface, and a second surface which is disposed adjacently to the first surface. The handle is formed of a handle body extending from one end side toward the other end side, and slide portions which are respectively formed on both end sides of the handle body. The handle body is disposed on the first surface. Slide receiving portions which hold the slide portions in a slidable manner are formed on the second surface.
