Abstract: A generator system for connection to a vehicle axle. The generator system includes: an electrically-actuated clutch having an engaged position and a disengaged position; a generator and a processor. The generator includes: a rotor configured to be selectively connected, via the clutch, to the vehicle axle; and a stator. In the engaged position, the rotor is connected to the vehicle axle via the clutch such that torque from the vehicle axle is transmitted to the rotor. In the disengaged position, torque from the vehicle axle is not transmitted to the rotor. The processor is configured to control the clutch to actuate between the engaged and disengaged positions, and the processor is configured to monitor an electrical output of the generator, wherein the processor is configured to command the clutch to move to the disengaged position if the electrical output moves outside a predetermined range.

Abstract: An electrical portal wheel hub system is coupled with a wheel of a vehicle and utilizes an electric motor/generator configured to drive the wheel or generate power through application of braking torque to the wheel, and may be coupled with two or more wheels of the vehicle, wherein generated power is provided to a portal hub battery. The portal hub battery may provide power to the electric motors, or to other electrical devices or batteries of the vehicle. The vehicle may include a trailer or non-driven wheels having a connecting axle and an electrical portal hub may be coupled to these otherwise, non-driven wheels. The vehicle may be an electric vehicle and the electrical portal wheel hub system may provide power to a vehicle battery that provides power to drive the wheels of the vehicle. A controller may control power from the portal hub battery to the electric motor/generators and or other battery and devices to provide energy efficiency.
