Fundamentals of Multi-Kinetic Flywheel Battery Technology

The multi-kinetic flywheel battery stores energy from multiple flywheels that rotate synchronously and together around a single central axis, which accumulates and redistributes the energy. The system is innovative because currently, only mono-flywheel batteries exist, which follow the same physical principle but have a lower energy storage capacity for the same mass and volume of the product.

The project is entirely sustainable. The product does not require any metals or rare earth elements for manufacturing and can be replicated virtually anywhere in the world.

The system has been patented with international extension.

Moreover, flywheel battery technology is adopted by NASA in the aerospace sector.

To summarize the technology in use, we take the following description from Wikipedia as a reference: “A flywheel battery or FES (Flywheel Energy Storage) is an electromechanical device used for storing energy in the form of rotational kinetic energy.

The basic idea is to accumulate energy by placing a flywheel in rapid rotation, thus creating an inertial battery.”

This concept is very interesting because large amounts of energy can be stored in a “small” object (good specific energy capacity) compared to other types of energy storage, such as electrochemical cells.

When the flywheel battery is not connected to any device, it allows energy levels to be maintained over time, measurable on the scale of decades, before the flywheel slows down to a non-operational movement and thus discharges. In cases where high outputs, ultra-fast recharge cycles, and minimal maintenance are added, it becomes clear that the flywheel battery can have much higher performance than the equivalent electrochemical technology and is more independent from the distribution network.

Until recently, the technology had been used primarily at the prototype and experimental level, but in recent years, it has been increasingly employed in many highly specialized applications (aerospace industry, automotive, etc.) and demonstrative projects (automotive prototypes, concept cars, etc.).
