Meet our flywheel energy storage device built to meet the needs of utility grid operators and C&I buildings. Nova Spin, our flywheel battery, stores energy kinetically. In doing so, it avoids many of the limitations of chemical batteries.
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).
Dai Xingjian et al. designed a variable cross-section alloy steel energy storage flywheel with rated speed of 2700 r/min and energy storage of 60 MJ to meet the technical requirements for energy and power of the energy storage unit in the hybrid power system of oil rig, and proposed a new scheme of keyless connection with the motor spindle.
To take advantage of this stored electricity, one simply lets the flywheel drive the motor which will produce an electric current that can be used again. In this way, the flywheel system can act as a battery. An example of a modern flywheel system can be seen in Fig. 1.
This means the maximum energy of the flywheel is independent of the chosen radius, and purely a function of the material properties and our choice of the value of M. If we assume a reasonable value for the tensile strength of stainless steel around 800 MPa and density of approximately 8000 kg/m 3, we have that [2-3]
The most fuel efficient battery array achieves 3% higher fuel economy than the most fuel efficient flywheel and roughly 4% higher fuel economy than the standard flywheel, though both of these flywheel combinations have the potential to be less expensive than the most fuel efficient battery array.
