A novel continuously variable transmission flywheel hybrid electric powertrain

This paper presents a novel CVT flywheel hybrid-electric powertrain whose Advantages include two kinds of energy exchange system, one is the ISG set that can transfer the energy between the mechanic and electric; another is the CVT flywheel system that can store the superfluous power as mechanic energy directly, and releases the mechanic energy when the driveline accelerates, which is reverse with the normal flywheel. The proposed hybrid-power system is explained firstly and dynamic analyses are performed for the overall hybrid driveline. In addition, a simulation model of the CVT hybrid driveline vehicle is developed. Lastly, a design example is simulated in the Matlab/Simulink. The results show that the CVT flywheel hybrid-electric driveline is practicable.
