Selection of design scheme for electric vehicle flywheel energy storage

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 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.

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.

What is energy storage with flywheel?

The key point of energy storage with flywheel is to reduce the loss of mechanical energy, namely the loss of kinetic energy that consists of air friction resistance and rotary resistance. According to different means for the reduction of energy loss, FESS can be divided into low-speed flywheel system and high-speed flywheel system.

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.

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.
