PURPOSE:To enhance fuel efficiency by providing a superconducting power storage system which converts AC power, to be generated from a generator when a hydrogen automobile is coasting with accelerator thereof being opened, into rotary motion energy of flywheel and stores thus converted energy. CONSTITUTION:An engine 1 is driven with hydrogen fed from a hydrogen fuel tank 2 to rotate an AC generator 3 through a speed change gear l', a shaft 2', pulleys 3', 4' and a belt 5' so as to produce three-phase AC power which is then subjected to forward conversion 5. Even if an accelerator (not show) is opened to disconnect a clutch 6' during travel, the AC generator 3 generates AC power through inertia of the vehicle. A battery 6 is charge with DC power obtained through forward conversion 5 and feeds DC power to an electric load 8 while furthermore the DC power is subjected to reverse conversion 7 to produce VVVF power. Excessive three-phase AC power is used for rotating a flywheel (not shown) built in a superconducting power storage system 4 and stored in the form of rotary motion energy. |
