Patent number: 8222866Abstract: A control device turns on a system relay and relays. A first boost converter rectifies an AC voltage supplied through a connector and a first power supply line. Further, the boost converter responds to a signal from the control device to boost the rectified voltage, and outputs the boosted voltage to a second power supply line. A second boost converter receives a voltage from the second power supply line to convert the voltage in accordance with a signal from the control device for output to a third power supply line. Since the system relay and one relay are both turned on, first and second batteries are connected in parallel to the third power supply line and a ground line. The first and second batteries are thereby charged.Type: GrantFiled: October 21, 2008Date of Patent: July 17, 2012Assignee: Toyota Jidosha Kabushiki KaishaInventors: Tetsuya Sugimoto, Yoshihito Kondo, Koichi Sugiura, Yasuhiko Ishimaru

Patent number: 7781933Abstract: The present invention is intended to provide a winding arrangement of single star connection for a rotating electrical machine, capable of enhancing insulation performance in coils of the same phase. In such winding arrangement, a first coil U1 to a sixth coil U6 are formed respectively in coil arranging parts 1U to 6U. Next, a coil arranging part 7U is skipped and the seventh coil U7 is formed in a coil arranging part 8U. Then, a coil formed at the end of winding (eighth coil U8) is formed in the skipped coil arranging part 7U.Type: GrantFiled: February 22, 2007Date of Patent: August 24, 2010Assignee: Toyota Jidosha Kabushiki KaishaInventors: Satoshi Koide, Yasuhiko Ishimaru, Hiroshi Hattori

Patent number: 6553650Abstract: A circular wire with a circular cross section is wound on a coil reel. When a winding-form motor rotates a winding form, the circular wire is pulled and drawn from the coil reel. Rectangular forming rollers press the circular wire, so that a rectangular wire with a rectangular cross section is formed. The rectangular wire is directly wound on the winding form to be formed into a rectangular-wire coil. Because forming rectangular wire and winding on the winding form are carried out in a sequence of contiguous processes, a separate process for removing torsion set of the rectangular wire is unnecessary. The rectangular-wire coil can be formed from inexpensive circular material wire by a simple and low-cost apparatus. It is also possible and preferable to make dimensions and a shape of the rectangular wire variable by controlling clearance widths between the forming rollers and tension acting on the rectangular wire that has passed through the rollers.Type: GrantFiled: February 22, 2001Date of Patent: April 29, 2003Assignee: Toyota Jidosha Kabushiki KaishaInventors: Masayuki Nakamura, Yasutomo Kawabata, Masahiro Nishioka, Yasuhiko Ishimaru, Tetsuya Miura, Katsuhisa Endo

Patent number: 6375113Abstract: A coil is formed by winding a conductive wire around a winding frame that is being rotated about a rotational axis of the winding frame. Guide members contact the conductive wire being wound around the winding frame to define the winding position of the conductive wire. The guide members are supported by a link mechanism that is provided coaxially with the rotational axis so as to rotate synchronously with the winding frame. As a third actuator moves a driving link in the direction of the rotational axis, the guide members are moved in directions of a diameter of the winding frame. As a first actuator moves a holding link in the direction of the rotational axis, the guide members are moved in the direction of the rotational axis together with the holding link. As a second actuator extends or contracts an arm, one of the guide members is moved independently of another one of the guide members. The first, second and third actuators do not need to rotate together with the winding frame.Type: GrantFiled: May 2, 2000Date of Patent: April 23, 2002Assignee: Toyota Jidosha Kabushiki KaishaInventors: Yasuhiko Ishimaru, Yasuyuki Nishimoto
