  • Method of operating a vehicle and electric powertrain
    Patent number: 8502410
    Abstract: An electric powertrain comprises a high voltage bus an electric machine, and a traction inverter is coupled between a high voltage bus and the electric machine. An electric voltage for the high voltage bus is generated with the electric machine and the traction inverter when the electric machine is driven mechanically. The generated electric voltage is limited and converted to a predetermined voltage lower than the limited voltage. A unit of the vehicle, such as a cooling pump, is powered with the predetermined voltage.
    Type: Grant

  • Power device for a vehicle
    Patent number: 7982332
    Abstract: A power device for use in a vehicle includes a housing, a voltage converter, and a charge-storing device. The housing carries the voltage converter and the charge-storing device. The voltage converter includes a circuit that converts a power signal having a first voltage level to a second voltage level. The charge-storing device electrically couples with the voltage converter and stores the power signal having the second voltage level.
