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.
Boeing has developed a 5 kW h/3 kW small superconducting maglev flywheel energy storage test device. SMB is used to suspend the 600 kg rotor of the 5 kWh/250 kW FESS, but its stability is insufficient in the experiment, and damping needs to be increased .
The completed system is the world's largest-class flywheel power storage system using a superconducting magnetic bearing. It has 300-kW output capability and 100-kWh storage capacity, and contains a CFRP (carbon-fiber-reinforced-plastic) flywheel.
And Beacon Power, before its bankruptcy, focused largely on using flywheels as frequency regulators for power grids. But Ben Jawdat, the founder and CEO of Revterra, a flywheel startup based in Texas, thinks that his company has overcome the shortcomings, making flywheels capable of long-term energy storage for renewable energy.
FESS has been integrated with various renewable energy power generation designs. Gabriel Cimuca et al. proposed the use of flywheel energy storage systems to improve the power quality of wind power generation. The control effects of direct torque control (DTC) and flux-oriented control (FOC) were compared.
At full speed, the flywheel has 5 kW h of kinetic energy, and it can provide 3 kW of three-phase 208v power to a power load. Small versions of this flywheel will be able to operate at very high speeds, and may require the inherent low losses in HTS bearings to achieve these speeds .
