Abstract: Embodiments of the invention provide an electric machine module including an electric machine. The electric machine includes a rotor and a stator assembly, and an output shaft having a longitudinal axis that is circumscribed by a portion of the rotor. The output shaft may comprise an output shaft channel and the rotor may include a rotor channel, and the rotor and the output shaft channels may be in fluid communication. The machine further includes a coolant jacket at least partially within a sleeve member that circumscribes at least a portion of the stator assembly, and at least one pump mounted generally concentrically with respect to the output shaft, that is in fluid communication with the coolant jacket. Some embodiments of the electric machine module include coupling to a fluid system that is configured and arranged to transport fluid, such as the coolant, throughout the fluid system.

Abstract: An electric machine includes a housing having an interior portion, a stationary member including a stationary field is fixedly mounted to the housing and a movable member including a rotating field is rotatably mounted relative to the stationary member. A positive pressure introduction system is fluidically coupled to the housing. The positive pressure introduction system is configured and disposed to raise an internal pressure of the interior portion of the housing.

Abstract: A hybrid vehicle powertrain system includes a first prime mover, a first prime mover driven power transmission mechanism having a power take-off adapted to drive a vehicle accessory, and a second prime mover. The second prime mover is operable to drive the power transmission mechanism alone or in combination with the first prime mover to provide power to the power take-off through the power transmission mechanism. The invention further includes methods for operating a hybrid vehicle powertrain system.

Abstract: A battery control system for hybrid vehicle includes a hybrid powertrain battery, a vehicle accessory battery, and a prime mover driven generator adapted to charge the vehicle accessory battery. A detecting arrangement is configured to monitor the vehicle accessory battery's state of charge. A controller is configured to activate the prime mover to drive the generator and recharge the vehicle accessory battery in response to the vehicle accessory battery's state of charge falling below a first predetermined level, or transfer electrical power from the hybrid powertrain battery to the vehicle accessory battery in response to the vehicle accessory battery's state of charge falling below a second predetermined level. The invention further includes a method for controlling a hybrid vehicle powertrain system.

Abstract: A battery control system for controlling a state of charge of a hybrid vehicle battery includes a detecting arrangement for determining a vehicle operating state or an intended vehicle operating state and a controller for setting a target state of charge level of the battery based on the vehicle operating state or the intended vehicle operating state. The controller is operable to set a target state of charge level at a first level during a mobile vehicle operating state and at a second level during a stationary vehicle operating state or in anticipation of the vehicle operating in the stationary vehicle operating state. The invention further includes a method for controlling a state of charge of a hybrid vehicle battery.
