Patent number: 9543624Abstract: An electricity storage module includes a stack, holder members, and heat-transfer plate members. The stack is formed by stacking power storage elements having lead terminals protruding outward from end portions. The holder members are made of insulating resin and are attached to the end portions of the power storage elements, the holder members holding the power storage elements. The heat-transfer plate member are disposed between power storage elements adjacent in a stacking direction, the heat-transfer plate members made of heat conductive material. An engaging portion is provided on one of the holder members and the heat-transfer plate members, and an engaged portion arranged to be engaged by the engaging portion is provided on the other of the holder members and the heat-transfer plate members. The holder members and the heat-transfer plate members are integrated by mutual engagement of the engaging portions and the engaged portions.Type: GrantFiled: September 2, 2013Date of Patent: January 10, 2017Assignees: AUTONETWORKS TECHNOLOGIES, LTD., SUMITOMO WIRING SYSTEMS, LTD., SUMITOMO ELECTRIC INDUSTRIES, LTD.Inventors: Masakuni Kasugai, Hiroki Shimoda, Kazuyuki Nakagaki, Masato Tsutsuki, Makoto Higashikozono, Hisashi Sawada

Patent number: 9490094Abstract: An overcurrent protection apparatus that is connectable to a battery control unit to protect the battery control unit from an overcurrent. The overcurrent protection apparatus includes a fuse member that is provided with a fuse and a fusible wire that is connected in series to the fuse. The fusible wire is made of a conductor that has a melting point lower than that of copper, and has a fusing current value that is higher than that of the fuse. The fuse member is connected in series to the battery control unit.Type: GrantFiled: December 26, 2012Date of Patent: November 8, 2016Assignees: AUTONETWORKS TECHNOLOGIES, LTD., SUMITOMO WIRING SYSTEMS, LTD., SUMITOMO ELECTRIC INDUSTRIES, LTD.Inventors: Ryoya Okamoto, Kazuyuki Nakagaki, Tomotaka Kurozu, Takehiro Hosokawa, Yasuyuki Otsuka, Akiko Inoue, Ryoma Uegaki

Publication number: 20100051314Abstract: A shield conductor W comprises: a plurality of wires 10, a heat transfer member 30 made of synthetic resin and formed so as to tightly attach to the outer circumference of the wires and moreover collectively enwrap the wires 10, and a metal pipe 20 assembled in a manner so as to tightly attach to the outer circumference of the heat transfer member 30. The heat generated in the wires 10 is transmitted from the outer circumference of the insulating coating 12 to the heat transfer member 30, then transmitted within the heat transfer member 30, and then transmitted from the outer circumferential surface of the heat transfer member 30 to the inner circumference of the pipe 20, and is finally released to the air from the outer circumference of the pipe 20.Type: ApplicationFiled: December 4, 2007Publication date: March 4, 2010Applicants: AUTONETWORKS TECHNOLOGIES, LTD., SUMITOMO WIRING SYSTEMS, LTD., SUMITOMO ELECTRIC INDUSTRIES, LTD.Inventors: Kunihiko Watanabe, Kazuyuki Nakagaki, Fujio Sonoda
