Flywheel energy storage patent

What is a flywheel energy storage assembly?

The flywheel energy storage assembly includes a flywheel rotatably disposed in a flywheel housing, a fluid source, a braking actuator in fluid communication with the fluid source and an interior of the flywheel housing, a sensor, and a controller in communication with the sensor and the braking actuator.

Why are flywheels used as energy storage devices?

Prior Art The use of flywheels as energy storage devices is ancient art. The flywheel (FW) is an attractive means for storing energy for a number of reasons. In concept, it is a relatively simple device with which energy can be readily stored and extracted, either by mechanical means or by using electric motors and generators.

How to reduce unnecessary turbine starts in a flywheel energy storage system?

In yet a further embodiment of the disclosure a method is provided for reducing unnecessary turbine starts by making turbine start a function of the rotational velocity of a flywheel. Abstract: A crash management system for implementation in a flywheel energy storage system (FESS) is provided.

What is a flywheel gimbal system?

Abstract: A flywheel system has damped gimbal system suspending a motor generator which is in turn linked by means of any number of flexible couplings and rigid shafts to a flywheel rotor system so as to provide safe passive stability to the highly energized spinning rotor system and high torque transmitting capacity.

What is a flywheel assembly?

A flywheel assembly comprising: a cylindrical sleeve carried on said shaft, said sleeve closed at each of two opposing axial ends to define an enclosed volume; wherein said sleeve is deformed by expansion of said fluid within said enclosed volume to tightly engage said rotor.

What is a flywheel rotor?

The flywheel rotor has a unique axial profile to both maximize the energy density of the flywheel, to maximize the volumetric efficiency of the entire system and to provide a circumferential ridge to add balance weights without the damaging procedure of grinding away fibers.
