Patent number: 7654351Abstract: A battery box housing a battery is mounted between left and right side frames extending in a longitudinal direction of a vehicle body so that the battery box is offset to a left side of the vehicle body, and an intake duct and an exhaust duct for cooling air for cooling the battery are connected to an end of the battery box on a right side of the vehicle body. Therefore, it is possible not only to protect the battery between the left and right frames from a shock caused upon a side collision, but also to ensure a space for disposition of the intake duct and the exhaust duct while ensuring a volume of the battery box to the maximum. Moreover, the battery box is connected at its left and right ends to the left and right side frames.Type: GrantFiled: May 25, 2006Date of Patent: February 2, 2010Assignee: Honda Motor Co., Ltd.Inventors: Eiji Koike, Harumi Takedomi, Satoyoshi Oya, Kanae Ohkuma, Seiichi Sato

Patent number: 7500512Abstract: The present invention aims to cool high tension electrical equipment efficiently with a small, lightweight device. The high tension electrical equipment cooling structure is provided for cooling batteries which supply electricity to the operating motor via an inverter, and the inverter using cooling air, and comprises an equipment box for guiding cooling air introduced from a cooling air inlet port into a cooling air outlet port, and a fan for introducing cooling air from the cooling air inlet port. A shutter that consists of an elastic material is disposed inside the intake duct. The shutter closes off the cooling air flow path, and when negative pressure is generated downstream of the shutter due to the operation of the fan, the shutter undergoes elastic deformation, and as a result, the cooling air flow path is opened.Type: GrantFiled: December 15, 2005Date of Patent: March 10, 2009Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Osamu Hasegawa, Kazuhiko Aitaka, Harumi Takedomi

Patent number: 7399551Abstract: In a battery cooling structure, a battery case housing a large number of battery modules is formed into the shape of a rectangular tube having a cooling air inlet and a cooling air outlet, and V-shaped cooling air guide channels having a decreasing flow-path cross sectional area are provided on inner faces of air guide plates that define upper and lower faces of the rectangular tube. The flow of cooling air is deflected by these V-shaped cooling air guide channels toward a central part on the downstream side, thus effectively cooling the battery modules disposed in the central part, for which the cooling effect is poor to make uniform the temperature of the battery modules, resulting in a suppressed variation in capacity and lifetime. Moreover, since it is not necessary to provide a bypass passage in the battery case, it is possible to simplify the structure of the battery case, reduce the dimensions, and improve the degree of freedom in the layout.Type: GrantFiled: December 17, 2004Date of Patent: July 15, 2008Assignee: Honda Motor Co., Ltd.Inventors: Kazuhiko Yagi, Eiji Koike, Harumi Takedomi, Takeo Nishibori

Patent number: 7396075Abstract: A rear seat is foldable by moving downward a seat cushion and folding forward a seat back. A power source unit is disposed below a rear floor to the rear of the rear seat. When the rear seat is in an unfolded state, cooling air can be introduced from inside a vehicle compartment, through a space between a lower surface of the seat cushion and an upper surface of an underseat floor, into a cooling-air introduction port in the power source unit. When the rear seat is in a folded state, the cooling air is introduced from inside the vehicle compartment, through cooling-air introduction passages, into the cooling-air introduction port. Thus, the power source unit can be cooled irrespective of whether the rear seat is in the folded state, without reducing the foldability of the rear seat.Type: GrantFiled: June 29, 2006Date of Patent: July 8, 2008Assignee: Honda Motor Co., Ltd.Inventors: Kanae Ohkuma, Harumi Takedomi, Eiji Koike, Masao Kawata

Publication number: 20070238015Abstract: A vehicle power source includes a number of battery modules in a first layer on one end side in a battery module laminating direction which is smaller than the number of battery modules in a fourth layer on an other end side. A cooling-air supply port is opened over the entire region in the laminating direction of the battery modules, an air-introduction guide is provided on the downstream side in the cooling-air flow direction, and a coolant discharge port is opened at a position closer to the fourth layer side. A flow from the first layer side to the fourth layer side is formed on the downstream side in the cooling-air flow direction so as to efficiently cool the battery modules difficult to be cooled.Type: ApplicationFiled: April 3, 2007Publication date: October 11, 2007Applicant: HONDA MOTOR CO., LTD.Inventors: Shinya Kubota, Hideaki Sakai, Harumi Takedomi, Satoyoshi Oya
