Patent number: 6459167Abstract: In a system for controlling electromotive force of a motor of an electric vehicle, an intelligent-power switch unit (IPS1) is connected to a power supply line (10) between a battery (4) and a motor controller (7) in parallel with a main relay (6) instead of a precharge circuits having mechanical relays and charge resistors. The intelligent-power switch unit (IPS1) mainly has an electric-power-supply control unit including a MOSFET (QA) serving as a semiconductor switching device, and is integrated in one chip structure. Accordingly, the cost and size can be reduced, and damage of the motor controller (7) caused from a rush current occurring when electric power has been supplied can effectively be prevented.Type: GrantFiled: February 28, 2000Date of Patent: October 1, 2002Assignee: Yazaki CorporationInventor: Hidenori Yamanashi

Patent number: 6444911Abstract: A bus wiring plate body (20), for an electric coupling box, is arranged in a manner that bus bar members (23, 24) are wired between pre-hardening epoxy resin plates (21, 22) and these pre-hardening epoxy resin plates are subjected to a heat pressing process to thereby integrate the pre-hardening epoxy resin plates (21, 22) and the bus bar members (23, 24) in a laminated state. When hardened epoxy resin plates (25, 26) are disposed outside of the pre- hardening epoxy resin plates (21, 22), respectively, the strength of the bus bar wiring plate body (20) can be improved. Thus, since the bus bar members (23, 24) are sealed in an insulated state, leak current is reduced. Further, the thickness of the bus bar wiring plate body (20) is reduced to a large extent, so that the electric coupling box can be miniaturized and lightweighted.Type: GrantFiled: April 2, 2001Date of Patent: September 3, 2002Assignee: Yazaki CorporationInventors: Mitsuko Maruyama, Hidenori Yamanashi

Publication number: 20020061447Abstract: An electrode for secondary battery made of carbon material is provided, which is light in weight while excellent in charge-discharge properties and in durability in repetitive use. A material for electrode is obtained by intermixing a synthetic resin with vapor-phase growth carbon fibers to make the vapor-phase growth carbon fibers uniformly dispersed in the synthetic resin to obtain a mixture, molding the mixture into a predetermined shape to obtain a molded product, and heating the molded product at high temperature to convert it into a carbon-carbon composite material. The electrode for battery is made of thus obtained carbon-carbon composite material.Type: ApplicationFiled: January 24, 2002Publication date: May 23, 2002Applicant: YAZAKI CORPORATIONInventors: Toshiaki Kanno, Makoto Katsumata, Hidenori Yamanashi, Hitoshi Ushijima

Publication number: 20010025718Abstract: The bus bar wiring plate body (20) for an electric coupling box according to the present invention is arranged in a manner that bus bar members (23, 24) are wired between pre-hardening epoxy resin plates (21, 22) and these pre-hardening epoxy resin plates are subjected to the heat pressing process to thereby integrate the pre-hardening epoxy resin plates (21, 22) and the bus bar members (23, 24) in a laminated state. When hardened epoxy resin plates (25, 26) are disposed at the outsides of the pre-hardening epoxy resin plates (21, 22) as shown by phantom lines, respectively, the strength of the bus bar wiring plate body (20) can be improved. Thus, since the bus bar members (23, 24) are sealed in an insulated state, leak current can be reduced surely. Further, the thickness of the bus bar wiring plate body (20) can be reduced to a large extent, so that the electric coupling box can be miniaturized and lightweighted.Type: ApplicationFiled: April 2, 2001Publication date: October 4, 2001Inventors: Mitsuko Maruyama, Hidenori Yamanashi

Patent number: 6232746Abstract: A battery charging apparatus 1 includes a full-charging detecting system 11. While a battery is charged, the full-charging detecting system operates as follows. A charging current supplied from an DC power source is detected. The internal impedance is computed on the basis of the charging current thus detected and charging voltage of the DC power source. The full-charging of the battery is detected on the basis of the comparison between the internal impedance thus computed and a prescribed value. In this configuration, even when the full-charging capacity varies owing to the degradation of the battery, the full-charged state of the battery can be detected precisely.Type: GrantFiled: July 5, 2000Date of Patent: May 15, 2001Assignee: Yazaki CorporationInventor: Hidenori Yamanashi
