Electric vehicles are typical representatives of new energy vehicle technology applications, which are developing rapidly and the market is huge. Flywheel energy storage systems can be mainly used in the field of electric vehicle charging stations and on-board flywheels.
On-board flywheels: There are two charging methods for the on-board flywheel battery, one is to use electrical energy as input energy, and the second is to directly drive the flywheel to rotate through the transmission device with mechanical energy (mainly used for braking energy recovery of electric vehicles).
Throughout the process of reviewing the existing FESS applications and integration in the power system, the current research status shows that flywheel energy storage systems have the potential to provide fast and reliable frequency regulation services, which are crucial for maintaining grid stability and ensuring power quality.
Due to the advantage of flywheel, minimizing the operation times of BESS and giving priority of flywheel to respond the fluctuations is proved to be an available option to improve the life span of BESS, reduce the probability of explosion of BESS and secure operation of the hybrid energy storage system.
Moreover, flywheel energy storage system array (FESA) is a potential and promising alternative to other forms of ESS in power system applications for improving power system efficiency, stability and security . However, control systems of PV-FESS, WT-FESS and FESA are crucial to guarantee the FESS performance.
There are several advantages to using electric vehicle flywheels as an energy storage solution: High Power Density: Electric vehicle flywheels have a high power density, meaning that they can store a large amount of energy in a relatively small space. This makes them ideal for use in electric vehicles, where space is often at a premium.
