The alternative components in an electric/flywheel propulsion system are reviewed, including different continuously variable transmissions (CVT's), and a new arrangement is proposed for electric vehicles, called the "Sussex propulsion system". Computer simulations are developed which show the effects of using flywheel energy storage, as opposed to electrical regenerative braking, for a large urban delivery van, which originally incorporated an electronically-controlled motor. Vehicle performance and energy consumption are compared over different driving cycles, and the result of varying the flywheel energy capacity is shown. The design and operation of an experimental rig is described and the experimental results are compared with those obtained from a computer simulation,, in order to test the validity of the mathematical models. The results show that for urban use, an electric delivery van fitted with the Sussex propulsion system has a substantially reduced energy consumption and better performance than a comparable conventional electric vehicle. Therefore, an electric vehicle in the future would require a smaller, cheaper installed battery pack or would have a greater range between recharging.
