Hydrodynamic-driving flywheel battery

Abstract

The present invention discloses a hydrodynamic-driving flywheel battery, and the flywheel adopts an independent rotating operational mode. The flywheel independently operates with ultra high speed according to a principle that a supercharger rotor of an internal combustion engine adopts a floating bearing, and the rotating speed can reach to above 300000rpm. The product cost is reduced and the manufacturing process is simplified in a mode that a normal motor and a normal generator store energy and generate electricity energy with low speed, and the flywheel operates with high speed. The lubricating oil hydrodynamic driving achieves the acceleration and deceleration electrodeless control. The clutch switchover of a by-passing valve and the control of a pressure regulator valve enable the motor and the generator to achieve the effect of barrier-free clutch and gradual acceleration, and the useless work consumption of the flywheel is avoided. The product manufacturing cost is reduced by the utilization of the normal motor and the normal generator. The frictional force of the flywheel at high-speed rotating is reduced by the utilization of the floating bearing, and the lubricating oil hydrodynamic driving is performed so that the motor, the flywheel, and the generator smoothly transit in speed. The flywheel battery can achieve the requirement of multiple industries such as civil use and military use, thereby achieving high economic benefit and promoting technical development in the industry.

Description

Technical field: [0001] The product involved in the invention is widely used in the technical fields of environment-friendly batteries used in civil vehicles and military vehicles concealed. Background technique: [0002] In 1994, the Argonne (ANL) National Laboratory of the United States used carbon fiber to trial-produce an energy storage flywheel: the diameter was 38 cm, the mass was 11 kg, superconducting magnetic levitation was adopted, and the linear speed of the flywheel reached 1000 m / s. The energy it stores can light 10 100-watt bulbs for 2-5 hours. The lab is currently developing an energy storage wheel with an energy storage capacity of 50 kWh, with the ultimate goal of making it a flywheel with an energy storage capacity of 5,000 kWh. A power plant with a generating capacity of 1 million kilowatts needs about 200 such energy storage wheels. In 1992, American Flywheel Systems (AFS) developed an electromechanical battery (EMB) for automobiles. Each "battery" is 1...

Problems solved by technology

Because the existing flywheel battery has only one motor, it is used as both a motor and a generator, resulting in a very high speed on the same shaft; the motor rotor and the flywheel have the same speed, resulting in a rather complicated manufacturing process; As a result, the cost is too high to be applied to civilian industries; the application of new green energy is hindered
