(3) during vehicle launch, if the rotating speed of inertial flywheel is higher than minimum setting rotating speed, the combination of closed-center system controller control magnetic clutch, inertial flywheel provides whole driving powers, keeps the inverter of storage battery to close simultaneously;
(4) during car brakeing, the braking kinetic energy of vehicle is reclaimed in the combination of closed-center system controller control magnetic clutch, and control inverter is closed simultaneously;
(5) during normal vehicle operation, if the accumulator electric-quantity abundance adopts pure motorized motions mode, tail-off, magnetic clutch disconnects, and inertial flywheel is not worked, and the driving power of car load is provided by storage battery fully; If when the electric weight of storage battery was not enough, engine starting also worked in best fuel-economy district, inverter is opened, and the unnecessary power of driving engine is battery charge.
(6) during the vehicle brish acceleration, the magnetic clutch combination, inverter is opened, and inertial flywheel and storage battery provide auxiliary power simultaneously, and the auxiliary engine powered vehicle guarantees that simultaneously engine operation is in best fuel-economy district.
Solved the requirement of motor vehicle driven by mixed power, improved the cycle efficiency of closed-center system, reached the purpose of this utility model energy storing device high power density and high-energy-density.
Advantage is: when car load normally moved, storage battery provided car load required average power, guarantee battery-efficient, work reposefully, when inertial flywheel is used to satisfy the starting, braking of vehicle and acceleration to the demand of high power density.Solved needs of problems to closed-center system high power density, high-energy-density, having solved storage battery big electric current moment discharges and recharges difficulty, shortcoming that specific power is low, and the storage battery flywheel energy storage system adopts existing product, have simple in structure, cost is low, technology maturation, system life are long.
