Experimental Research of a Flywheel Hybrid Vehicle

Abstract:

A flow-coupled flywheel hybrid vehicle was proposed which has simpler configuration, fewer components and easier control method. And it was confirmed that this system had enough capability to recover vehicle kinetic energy that might otherwise be lost as heat during braking. Then, more attentions were paid to initial speed of recovery flywheel and displacement ratio of variable displacement pump/motor that influenced recovery efficiency of the proposed hybrid vehicle. It is also significant to point out that in order to improve recovery efficiency, the displacement size of variable displacement pump/motor is required so as to make it operates as maximum displacement, and the initial speed of the recovery flywheel is limited at a suitable scope (about 1000rpm~3000rpm) with regard to the windage and axial loss and the amount of energy storage. Hence, it is indicated that this type of hybrid vehicle can be as an optional configuration to widely use in hybrid vehicle.
