Abstract

The invention discloses a flywheel energy storage device, which comprises a vacuum container (2), a motor (3), a flywheel body (4), a power electronic converter (6) and a protective shell (7), whereinthe protective shell (7) is internally provided with the flywheel body (4); the vacuum container (2) is internally provided with the motor; the flywheel body (4) is connected with the motor (3) through a connection rod (8); the flywheel body (4) is matched with the motor (3); one side of the protective shell (7) is provided with the power electronic converter (6); and the power electronic converter (6) is matched with the vacuum container (2). The flywheel energy storage device has the advantages that the structure is simple and reasonable, the efficiency is high, the service life is long, much energy can be stored, and the use is extremely convenient.

Description

technical field [0001] The invention relates to the technical field of energy storage devices, in particular to a flywheel energy storage device. Background technique [0002] The "flywheel" energy storage element has been used by people for thousands of years, from the ancient spinning wheel to the steam engine during the industrial revolution. In the past, its inertia was mainly used to balance the speed and break through the "dead point". The working cycle of the flywheel is very short, and the time for each rotation is less than one second. In such a short time, the energy consumption of the flywheel is negligible. Electric vehicles using chemical batteries have been tested for decades, but have not yet entered the practical stage. Solar energy, wind energy, tidal energy, and wave energy all have storage problems. At present, they mainly rely on chemical batteries. However, due to the limitation of the life and efficiency of chemical batteries, they cannot be widely use...
