Abstract
System and method for the combination of a flywheel and motor/generator inside a wheel hub for hybrid vehicle propulsion. The flywheel and motor/generator are connected by a planetary gear system, in which a first port is connected to the flywheel, a second port is connected to the wheel hub, and a third port is connected to a motor/generator. An additional motor/generator may be used at one of the first port and second port. The system may be used in an electric-kinetic hybrid mode, or in a fuel-kinetic hybrid mode, when used in a vehicle having an internal combustion engine as the prime mover. Efficiency of energy storage and release is significantly improved in comparison to prior art.

14. A method of operating a kinetic hybrid vehicle that includes a flywheel connected to a first port of a continuously variable transmission, a first motor connected to a third port of the continuously variable transmission, and a second motor and a wheel of the vehicle connected to the second port of the continuously variable transmission, the method comprising:
-
determining the vehicle speed in real-time, and selecting one of three operation states, wherein the first operation state comprises operating the first motor on the third port of the continuously variable transmission to release energy from the flywheel on the first port to the wheel on the second port of the continuously variable transmission, or to store energy from the wheel on the second port to the flywheel on the first port, while the second motor is inactive, the second operation state comprises operating the second motor on the second port of the continuously variable transmission to drive the wheel on the same port while the first motor is inactive and both the first port and the third port rotate freely, and the third operation state comprises operating both the first motor and the second motor to drive the wheel on the second port of the continuously variable transmission.
