Publication number: 20220352593Abstract: 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.Type: ApplicationFiled: May 29, 2020Publication date: November 3, 2022Inventors: Tomoshige INOUE, Yasutaka MIYAWAKI

Patent number: 10830823Abstract: 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.Type: GrantFiled: March 24, 2017Date of Patent: November 10, 2020Assignee: GS YUASA INTERNATIONAL LTD.Inventors: Tomoshige Inoue, Kenichi Sejima

Patent number: 10141752Abstract: 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.Type: GrantFiled: February 12, 2016Date of Patent: November 27, 2018Assignees: YAZAKI CORPORATION, GS YUASA INTERNATIONAL LTD.Inventors: Masashi Sekizaki, Michito Enomoto, Tomoshige Inoue

Patent number: 9746522Abstract: A switch failure diagnosis device for using in a current path between an electric device and an electric storage device includes plural switches, a switch terminal voltage detector, and a controller. The switches are connected parallel to each other in the current path. The switch terminal voltage detector outputs a switch terminal voltage detection signal. The controller is configured to select the switches at different time in sequence and input an open instruction signal to each switch at the time when the switch is selected, and to determine, based on the switch terminal voltage detection signal output while the open instruction signal is given, that at least one of the switches has a failure if the detected voltage is in a failure determination range.Type: GrantFiled: December 4, 2015Date of Patent: August 29, 2017Assignee: GS YUASA INTERNATIONAL LTD.Inventors: Takeyuki Shiraishi, Tomohiro Kawauchi, Takeshi Itagaki, Tomoshige Inoue, Daisuke Konishi
