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.
Flywheels have a solid foundation for reliability in meeting the demands of utility scale energy storage. For instance, the M25 system has a rated energy storage capacity of 25 kilowatt hours (kWh) at the beginning of the project, with a 4-hour discharge duration (6.2kW power rating).
The potential failure modes for a flywheel energy storage system include: loss of vacuum, overspeed, top and bottom bearing failure, and rotor burst. Testing for these failure modes included collecting temperatures, accelerations, electrical parameters, video footage, and photographs as appropriate. Sizing flywheel energy storage capacity to meet a utility scale requires integrating many units into an array.
A flywheel is a mechanical device that stores kinetic or moving energy. The basic concept of a spinning mass is well-established and is found in many mechanical systems, including flywheels. This passage explains the concept of a flywheel, not specifically how it works in the context of energy storage.
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 .
Amber Kinetics has validated the readiness of the M32 flywheel design for utility scale energy storage. The original plans of the project have been surpassed for this purpose.
