A vehicle includes a battery, an inverter, a permanent magnet electric machine, and a controller. The controller commands discharge of a storage element of the inverter through the permanent magnet electric machine via a current having a zero quadrature axis component and a positive direct axis component.

A propulsion system for a hybrid electric vehicle comprises a traction motor having first and second stator windings; a power source having a DC power output coupled to the first windings; a battery having a DC power output coupled to the second windings; and a controller to independently control: (i) a first power level output at the first DC power output, and (ii) a second power level of motive power output by the traction motor; wherein responsive to a signal to set the second power level less than full capacity of the traction motor, the controller provides a power difference between the first and second power levels from the second windings to the battery.

A method for operating a hybrid vehicle includes, determining a shift element to be utilized for decoupling of slip and a decoupling differential speed depending on whether a starting process is carried out, depending on whether the transmission is transferred from a torque-transmitting state into a non-torque-transmitting state or from a non-torque-transmitting state into a torque-transmitting state, depending on whether a gear ratio change is carried out, and depending on whether the hybrid vehicle includes a hydrodynamic starting component.

An energy storage system for a military vehicle includes a lower support, a battery supported on the lower support, a bracket coupled to the battery, and an upper isolator mount coupled between the bracket and a wall. The upper isolator mount is configured to provide front-to-back vibration isolation of the battery relative to the wall.

An electrical portal wheel hub system is coupled with a wheel and has an electric motor/generator, such as an axial flux motor configured therein and configured to provide power or torque to drive the wheel. The electric motor may be offset vertically from the rotational axis of the wheel to provide additional ground clearance. The electric motor may drive an input gear that is coupled with an output gear that in turns drives the wheel mount and wheel. The gearing ratio can be selected based on the application. A drive axle may from the vehicle may couple with the electric motor and the electric motor may be used to provide supplemental power to drive the wheels. The hub casing may provide mounts for the upper and lower A-arms as well as for a steering arm. The electric motor may act as a generator to charge a battery.
