Patent number: 7550228Abstract: The car power source battery apparatus houses a plurality of battery modules in a holder case. Battery modules have batteries connected in a straight-line fashion, and boundary regions between batteries are covered with elastomer cylinders, which can flexibly deform. The outline of elastomer cylinder regions of a battery module is wider than the outline of battery regions not covered by elastomer cylinders. The holder case is divided into a first holder and a second holder to form holding compartments to retain battery modules. The inside shape of a holding compartment is a cylinder shape which is narrower than the outline of elastomer cylinder regions and wider than the outline of battery regions. Elastomer cylinder regions are resiliently compressed by holding compartment inside surfaces to hold battery modules, and cooling gaps are established between battery regions and holding compartment inside surfaces.Type: GrantFiled: July 22, 2005Date of Patent: June 23, 2009Assignee: Sanyo Electric Co., Ltd.Inventor: Ryosaku Izawa

Publication number: 20070017720Abstract: A power device for a vehicle includes a base portion to be mounted on the vehicle, a resin component having a through hole which is to be fixed to the base portion, a metal sleeve inserted through an internal surface of the through hole of the resin component and having a flange on an opposed surface to the base portion, and a metal screw inserted through the metal sleeve inserted in the through hole of the resin component, thereby fixing the resin component to the base portion through the metal sleeve. The base portion has a female screw member into which a tip portion of the metal screw is to be screwed and has a support member provided on an opposed surface to the metal sleeve. In the power device, the metal screw is inserted through the metal sleeve to screw a screw portion on a tip into the female screw member and fixes the metal sleeve to the base portion, thereby securing the resin component to the base portion.Type: ApplicationFiled: July 25, 2005Publication date: January 25, 2007Inventors: Kazuhiro Fujii, Ryosaku Izawa, Koichi Aoishi

Publication number: 20060028183Abstract: A power device for a vehicle includes a plurality of batteries, a case accommodating the batteries, a blower for forcibly supplying air to the batteries accommodated in the case, thereby cooling them, and a temperature sensor for coming in contact with a surface of the battery to detect a temperature of the battery. A thermal portion for detecting the temperature of the battery of the temperature sensor includes a thermal element to be thermally coupled to the surface of the battery, and a heat insulating material having a cushioning property to be elastically compressed which serves to thermally insulate the thermal element provided on the surface of the battery from the cooling air, and the thermal element is isolated from the cooling air supplied forcibly by means of the heat insulating material having the cushioning property, thereby detecting the temperature of the battery.Type: ApplicationFiled: July 25, 2005Publication date: February 9, 2006Inventors: Ryosaku Izawa, Naoki Tsuzurano
