Publication number: 20180370384Abstract: To achieve effective use of space in a vehicle compartment by optimizing arrangement of a high-voltage control equipment unit including batteries. The high-voltage control equipment unit (20) includes two batteries (50-1, 50-2) juxtaposed in the width direction of the vehicle (1), a high-voltage electrical component (56) for controlling power delivery from the batteries (50-1, 50-2), and a case (30) integrally housing the batteries (50-1, 50-2) and the high-voltage electrical component (56). The two batteries (50-1, 50-2) are mounted under front seats (5-1, 5-2). The high-voltage electrical component (56) is mounted between the two front seats (5-1, 5-2) in the vehicle width direction. On a bottom surface (33) of the case (30), a recessed portion (32) in which a propeller shaft (4) extending in the longitudinal direction of the vehicle (1) is formed.Type: ApplicationFiled: August 24, 2016Publication date: December 27, 2018Applicant: HONDA MOTOR CO., LTD.Inventors: Tomoatsu Murakami, Hidetomo Fujiwara

Patent number: 8403090Abstract: A power supply apparatus includes a plurality of battery modules, a support plate, a plurality of first reinforcing projections, and a plurality of second reinforcing projections. The support plate supports the battery modules and includes a first plate and a second plate. The first plate thermally contacts bottom surfaces of the battery modules. The second plate is placed on a bottom surface of the first plate to define cooling spaces between the first and second plates. A coolant is to flow in the cooling spaces. The plurality of first reinforcing projections is provided on at least one of the first and second plates. The first reinforcing projections project into the cooling spaces and extend in a first direction. The plurality of second reinforcing projections is provided on a top surface of the first plate and extending in a second direction intersecting with the first direction.Type: GrantFiled: April 13, 2012Date of Patent: March 26, 2013Assignee: Honda Motor Co., Ltd.Inventors: Hidetomo Fujiwara, Atsushi Sakurai, Kazuhisa In
