Patent number: 10074844Abstract: To connect a bus bar plate to a battery module, a plurality of recess portions provided on a plurality of holders so as to be spaced in the stacking direction are engaged with a plurality of projection portions provided on the bus bar plate to be spaced in the stacking direction. Since the lengths “a” of the plurality of projection portions are the same, and the plurality of recess portions are formed from a first recess portion having a length “a” and a second recess portion having a length “b” larger than the length “a,” the precision of positioning of the bus bar plate can be ensured by engagement between the projecting portion and the first recess portion, and even if the gap between the projecting portions or the recess portions is nonuniform, it is possible to assemble the bus bar plate onto the holder with high precision.Type: GrantFiled: December 5, 2012Date of Patent: September 11, 2018Assignee: HONDA MOTOR CO., LTD.Inventors: Shinji Wada, Arihisa Kimura, Koichi Yamamoto

Patent number: 9692090Abstract: A battery cooling structure includes a cooling plate and an electrically insulative sheet. The cooling plate is to support a cooling surface of a battery module to cool the battery module including a plurality of battery cells arranged side by side. The electrically insulative sheet has an electrical non-conductivity and is disposed between the cooling surface of the battery module and the cooling plate to transfer heat from the cooling surface to the cooling plate.Type: GrantFiled: November 7, 2012Date of Patent: June 27, 2017Assignee: HONDA MOTOR CO., LTD.Inventors: Arihisa Kimura, Goichi Katayama, Koichi Yamamoto, Masato Fujioka

Patent number: 9647304Abstract: A battery cooling structure in which a heat transfer sheet that can be deformed by pressure is held between a cooling plate and a cooling surface of a battery module in which a plurality of battery cells are stacked, and heat of the battery module is transferred from the cooling surface to the cooling plate via the heat transfer sheet to thus carry out cooling, wherein the cooling plate is a hollow member in which a cooling medium passage is formed for a cooling medium to flow, and the heat transfer sheet is formed so as to have a larger thickness in a middle part than in an outer peripheral part.Type: GrantFiled: December 5, 2012Date of Patent: May 9, 2017Assignee: HONDA MOTOR CO., LTD.Inventors: Arihisa Kimura, Goichi Katayama

Patent number: 9509023Abstract: When a battery is supported on a cooling plate, since a heat transfer sheet, which is deformable by pressure, is held between the cooling plate and a cooling surface of the battery, it is possible to efficiently transfer the heat of the battery from the cooling surface to the cooling plate via the heat transfer sheet, thereby enhancing the effect in cooling the battery. Since the heat transfer sheet includes a plurality of through holes, compared with a case in which a heat transfer sheet does not include the through hole, the reaction force generated by restoration of the compressively deformed heat transfer sheet to its original shape is decreased, thus reducing the load acting on a mounting flange securing the battery to the cooling plate and thereby preventing the mounting flange from being broken.Type: GrantFiled: December 5, 2012Date of Patent: November 29, 2016Assignee: HONDA MOTOR CO., LTD.Inventors: Goichi Katayama, Takeshi Ueda, Tooru Ohgaki, Arihisa Kimura, Shuji Sasaki, Kenji Shimizu

Publication number: 20120121962Abstract: A battery cooling structure includes a first battery group, a second battery group, a third battery group, a first duct, a second duct, a third duct, a fourth duct, a fifth duct, a first connecting duct, a second connecting duct, a third connecting duct, and a bypass duct. The first duct is configured to allow a cooling medium after heat exchange to flow through the first duct. The second duct is configured to allow a cooling medium after heat exchange to flow through the second duct. The fifth duct is configured to allow a cooling medium after heat exchange to flow through the fifth duct. The bypass duct connects the fifth duct to the second duct or to the first duct.Type: ApplicationFiled: October 25, 2011Publication date: May 17, 2012Applicant: HONDA MOTOR CO., LTD.Inventors: Goichi KATAYAMA, Koichi Yamamoto, Arihisa Kimura
