Patent number: 8684118Abstract: A cooling structure having a sufficient cooling efficiency in cooling an electricity storage device while securing a living space in a vehicle cabin when installed in a compact vehicle having a short distance from a rear seat to the rear end of the vehicle. A battery is contained in an IPU installed in the vehicle. The cooling structure for the battery has an air inlet opened into the vehicle cabin, an air intake duct extending from the air inlet to the IPU and a cover disposed to cover the air inlet and having a hole communicating the air intake duct with the inner side of the vehicle cabin. The air inlet has an opening inclined toward the inner side of the vehicle cabin in one side section of a rear portion of the vehicle cabin near a C-pillar located obliquely posterior to a rear seat.Type: GrantFiled: October 29, 2010Date of Patent: April 1, 2014Assignee: Honda Motor Co., Ltd.Inventors: Keishi Kosaka, Byoungju Lee, Yoshiaki Takahashi, Tohru Kuribayashi, Hidehisa Mokudai

Patent number: 7436651Abstract: The present invention provides an electric double layer capacitor which has electrodes made of an alkali-activated carbon, prepared from a graphitic material, useful in manufacturing high-capacitance capacitors and which has an electrolytic solution containing chain carbonate and/or cyclic carbonate. Even if the electric double layer capacitor is used under high-temperature and high-voltage conditions, chain carbonate and/or cyclic carbonate is prevented from being degraded and the amount of generated gas is slight. The electric double layer capacitor has high initial performance and energy density and the performance of the electric double layer capacitor is maintained high.Type: GrantFiled: June 26, 2006Date of Patent: October 14, 2008Assignees: Mitsubishi Chemical Corporation, Honda Motor Co., Ltd.Inventors: Masayuki Takeda, Hideo Nagaoka, Hiroo Miyauchi, Takeshi Fujino, Byoungju Lee

Patent number: 7391603Abstract: In an electric double layer capacitor and electrolytic solution, decomposition of at least one of an open-chain carbonate and a cyclic carbonate can be controlled under high temperature conditions, initial performance and maintained ratio of capacitance are superior, and energy density is high, when graphitized alkali-activated carbon is used as an electrode material and at least one of an open-chain carbonate and a cyclic carbonate is used in an organic electrolytic solution. The electric double layer capacitor includes electrodes containing alkali-activated carbon including graphitized carbon material, and an organic electrolytic solution in which a supporting salt is dissolved in solvent including aromatic carboxylate and at least one of an open-chain carbonate and a cyclic carbonate, in which the content of the aromatic carboxylate is not more than 50 weight % relative to the total weight of the solvent.Type: GrantFiled: May 17, 2006Date of Patent: June 24, 2008Assignees: Honda Motor Co., Ltd., Mitsubishi Chemical CorporationInventors: Takeshi Fujino, Byoungju Lee, Masayuki Takeda, Hideo Nagaoka, Hiroo Miyauchi, Daisuke Noda
