  • Patent number: 8332090
    Abstract: A hybrid vehicle and a method for operating a hybrid vehicle are provided, the vehicle including at least a first drive unit and a second drive unit coupled to the first drive unit, wherein the second driving unit recovers kinetic energy during braking the hybrid vehicle, a transmission unit which can be coupled to the first and/or second drive unit and a drive axle. It is proposed to change the transmission ratio of the transmission unit depending on a desired amount of energy recovered by the second drive unit during regenerative braking or a predetermined time period before the anticipated start of regenerative braking.
    Type: Grant
    Filed: February 8, 2008
    Date of Patent: December 11, 2012

  • Publication number: 20110053021
    Abstract: A method and an arrangement for reforming a hydrocarbon fuel such as dimethyl ether (DME), methanol, ethanol, propanol, or any variants or other oxidized fuels is disclosed for generating hydrogen especially for supplying a fuel cell. Furthermore, a fuel cell system is disclosed which includes such an arrangement, especially for providing power to a stationary or mobile power consuming unit like especially an auxiliary power unit (APU) for application in aircraft, ships and vehicles, or as a part of a hybrid drive or as a sole driving unit for, e.g., a ship or a vehicle.
