Patent number: 7990105Abstract: A high voltage power supply device has a plurality of battery modules connected to each other in series by coupling a safety plug unit to a safety plug unit connecting base to output a series voltage from a power supply output coupler. The safety plug unit connects/disconnects electrode terminals of all the battery modules to each other. Female electrode bodies electrically connected to power supply terminals of the respective battery modules are collectively positioned in a limited area and are arranged at equal intervals on the safety plug unit connecting base. An output voltage of each battery module is set to be lower than 50V to reduce the risk of injury during use, inspection or maintenance of the high voltage power supply device and to downsize the device.Type: GrantFiled: March 16, 2007Date of Patent: August 2, 2011Assignee: Yamaha Hatsudoki Kabushiki KaishaInventors: Takaie Matsumoto, Yukiharu Hosoi, Shigeto Suzuki, Takeshi Ikeda, Toshinori Fukudome

Patent number: 7667342Abstract: A power supply system that supplies high-voltage power to a vehicle drive motor is provided to achieve reduction in size, weight and cost of power supply. The power supply system includes a plurality of battery modules connected in series. With the intermediate connection point of the battery modules as an electrical neutral point, power is supplied to a three-level inverter via a three-level-potential high-voltage power supply line having potentials of +150V and ?150V relative to this neutral point. In the three-level inverter, direct-current electric power is converted into three-phase alternating-current electric power to drive an electric motor. Accordingly, the withstand-voltage performance required of control units or control elements connected to the high-voltage power supply line can be halved as compared with the related art, thereby allowing a reduction in the size, weight, and cost of the power supply system.Type: GrantFiled: March 16, 2007Date of Patent: February 23, 2010Assignee: Yamaha Hatsudoki Kabushiki KaishaInventors: Takaie Matsumoto, Yukiharu Hosoi, Shigeto Suzuki, Takeshi Ikeda, Toshinori Fukudome

Patent number: 7431112Abstract: A hybrid motorcycle capable of mounting thereon a hybrid-type drive unit, which does not project in a vehicle width direction and can be mounted even on a motorcycle having a limited vehicle width, includes a power distributing device positioned between a generator and a motor, and a reduction device arranged rearwardly of the power distributing device. A front end of a drive-wheel transmission device is journaled on a rear end of a central storage casing so that a rear end side of the drive-wheel transmission device is vertically swingable, and a rear wheel is journaled on the rear end of the drive-wheel transmission device. The power distributing device includes a sun gear, planetary gears, a planetary carrier, and a ring gear. Further, a carrier shaft projects from a rotor shaft and rotation of a crank shaft is transmitted through a intermediate gear portion to the projecting end of the carrier shaft.Type: GrantFiled: February 15, 2007Date of Patent: October 7, 2008Assignee: Yamaha Hatsudoki Kabushiki KaishaInventors: Tatsuyuki Masuda, Toshinori Fukudome, Shinji Sasamoto
