Patent number: 11171393Abstract: According to one embodiment, a battery module includes a plurality of sub-modules. The plurality of sub-modules are integrated. Each of the plurality of sub-modules includes a cell group configured using a plurality of cells connected in series. The plurality of cells configuring the cell group are arranged linearly such that intra-cell current directions are parallel and the intra-cell current direction of each of the cells is opposite to the intra-cell current direction of the cell adjacent to each cell in the cell group. Each of the plurality of sub-modules includes an input terminal to input a current to the cell group and an output terminal to output the current from the cell group.Type: GrantFiled: February 20, 2020Date of Patent: November 9, 2021Assignee: Kabushiki Kaisha ToshibaInventors: Hiroyuki Kobayashi, Tomomi Kageyama, Takeshi Yasuda, Kaoru Koiwa, Seiji Ito, Tomonori Ezoe

Patent number: 9972811Abstract: A battery module according to one embodiment includes a stack of battery cells. The battery module also includes a fitting portion provided with at least one of a concave portion or a convex portion formed on a stack surface of each of the battery cells of the stack. The battery module further includes: a first frame which is fitted with one side surface of the stack and constrains the battery cells in a stacking direction; a second frame which is fitted with another side surface of the stack and constrains the battery cells in the stacking direction; and press members located at respective ends of the stack and connected to the first frame and the second frame. The press members are configured to generate an urging force for pressing electrode members of the battery cells from outside the battery cells.Type: GrantFiled: August 27, 2015Date of Patent: May 15, 2018Assignee: KABUSHIKI KAISHA TOSHIBAInventors: Takaya Ogawa, Tomonori Ezoe
