Abstract:
An electric powertrain includes an electric machine, an inverter connected to the electric machine, and an energy storage system for providing an electric current. The energy storage system includes a first energy storage device operable at a first device voltage, and a second energy storage device operable at a second device voltage. A plurality of low-loss switching devices interconnect the first energy storage device and the second energy storage device. The switching devices are selectively controllable between a first operating mode for providing the electric current at a first system voltage, and a second operating mode for providing the electric current at a second system voltage. The first system voltage is different from the second system voltage.

Claim (Index 16):
A method of controlling an electric powertrain including an electric machine, an inverter connected to the electric machine, and an energy storage system connected to the inverter, the method comprising:\n providing the energy storage system to include:\n a first energy storage device operable at a first device voltage; \n a second energy storage device operable at a second device voltage; \n a first switching device selectively controllable between an on-state enabling electrical communication therethrough, and an off-state preventing electrical communication therethrough; \n a second switching device selectively controllable between an on-state enabling electrical communication therethrough, and an off-state preventing electrical communication therethrough; and \n a third switching device selectively controllable between an on-state enabling electrical communication therethrough, and an off-state preventing electrical communication therethrough; \n controlling the first switching device, the second switching device, and the third switching device to operate in a first operating mode to provide an electric current at a first system voltage when the electric machine is operating at a rotational speed that is less than a first defined threshold; and controlling the first switching device, the second switching device, and the third switching device to operate in a second operating mode to provide the electric current at a second system voltage when the electric machine is operating at a rotational speed that is greater than the first defined threshold.
