Patent for electric vehicle flywheel energy storage motor

Is flywheel energy storage system suitable for hybrid electric vehicle?

Simulation results indicate that flywheel energy storage system is quite suitable for hybrid electric vehicle and with fuzzy logic control strategy both the performance of ICE and ISG are optimized that reduces fuel consumption of vehicle to greater extent. Flywheel energy storage system (FESS) is different from chemical battery and fuel cell.

What is a high-speed flywheel system?

The high-speed flywheel system consists mainly of a flywheel, a motor and a generator. It is connected with exterior electrical systems through input or output electronic equipments and the power transported from exterior systems is converted from electric energy into mechanical energy by raising rotary speed of flywheel.

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.

What is flywheel energy storage system (fess)?

Flywheel energy storage system (FESS) is different from chemical battery and fuel cell. It is a new type of energy storage system that stores energy by mechanical form and was first applied in the field of space industry. With the development of flywheel technology, it is current be widely used in various industry fields.

How flywheel technology is used in automobile industry?

With the development of flywheel technology, it is current be widely used in various industry fields. The vehicle ‘AFS20’ which was produced by U.S. flywheel system Inc. with original shape of Daimler-Kreisler began the Popularization of FESS towards automobile industry.

How does a flywheel system work?

The Flywheel system is controlled by FCM, which receives commands of charging or discharging from HCU and then gives commands to the motor or generator of FESS. Except for harmonizing functions of all the controllers and determining energy management of vehicle, HCU also needs to deal with various fault signals.
