Abstract: A deterioration amount estimation device includes a calculation unit (CPU33) that calculates a deterioration amount of an energy storage device and an estimation unit (CPU33) that estimates a transient deterioration amount based on a deterioration amount calculated by the calculation unit and a continuous deterioration amount that does not decrease with time and continues. The transient deterioration amount is estimated, and the input/output of the energy storage device is limited to suppress an increase in the continuous deterioration amount.

Abstract: An electric storage device includes an electric storage element including an external terminal, and a bus bar connected to the external terminal. The bus bar includes a thin-walled portion and a thick-walled portion, the thin-walled portion being located around outer edges of the bus bar. The thin-walled portion and the external terminal are directly welded together. A thickness of the thin-walled portion is less than a thickness of a remaining portion of the bus bar including the thick-walled portion.

Abstract: An electric storage device includes an electrode assembly, a case that includes a defining wall and houses the electrode assembly, a sealing member that is arranged on the defining wall, and a conductive member that is electrically connected to the electrode assembly, the conductive member being supported by the sealing member. At least a portion of the defining wall where the sealing member is arranged includes an aluminum-based metallic material. The sealing member includes a material that is softer than the material for the at least a portion of the defining wall where the sealing member is arranged. The sealing member includes polyphenylene sulfide (PPS) resin and an elastomer. The elastomer is contained in an amount of 2% to 20% by weight. The conductive member is crimped in such a manner that the sealing member is pressed against the defining wall.

Abstract: The present invention is to improve the estimation accuracy of an SOC of a storage element. A storage element management device disclosed in the present description is a battery management device 50 that determines an SOC range indicating a state-of-charge of a secondary battery 30, and has a constitution including a central processing unit 61 that sets an overlapping range between an SOC range (i) R1, determined by a current integration method, and an SOC range (v) R2, determined by a voltage reference method in a stage where the SOC range (i) R1 is determined by the current integration method, as a new SOC range R3.

Abstract: A battery includes an output terminal, an electric storage device, a relay connected to the output terminal and the electric storage device, and a monitoring apparatus including a detector and a controller, the detector being configured to detect a variation value corresponding to an amount of charge of the electric storage device, the controller receiving an engine activation signal and switching a state of the relay to a closed state. If an engine is not started, the controller switches the state of the relay to an open state.
