The flywheel Residential Energy Storage System is an energy storage device for electromechanical energy conversion. It breaks through the limitations of chemical batteries and use physical methods to achieve energy storage. Through the two -way motor of the electric/power generation, the mechanical kinetic energy of the electric energy and the high -speed running wheels can be converted and stored, and the load interfaces of frequency regulation, rectification, constant voltage and different types of load are passed.

The flywheel body is the core component in the flywheel Residential Energy Storage System. The role is to strive to increase the extreme angle speed of the rotor, reduce the weight of the rotor, and maximize the energy storage energy of the flywheel Residential Energy Storage System.

The performance of the bearing system directly affects the reliability, efficiency and life of the flywheel Residential Energy Storage System. The application of the flywheel Residential Energy Storage System uses the magnetic suspension system to reduce the friction of the motor rotation, reduce mechanical loss, and improve energy storage efficiency.

The flywheel Residential Energy Storage System mainly includes three parts: the rotor system, the bearing system, and the conversion energy system. There are also some support systems, such as vacuum, deep cold, shell and control system.

1. System

During the flywheel rotation, the kinetic energy is proportional to the rotation of the flywheel. The rotation inertia of the flywheel is proportional to the quality of the 2 secondary square of the flywheel diameter and the flywheel (J = (0.5 ~ 1)*m*R^2, when the quality distribution of the flywheel is uniform, take 0.5, the quality is completely concentrated when the edge is taken 1) Essence

When the too huge and heavy flywheel rotates at high speed, it will be greatly centrifuged. It often exceeds the limit intensity of the flywheel material and is not safe. Therefore, it is limited to increase the kinetic energy of the flywheel by increasing flywheel rotation inertia.

2. Bearing system

The bearings that support rotors, support rotor motion, reduce friction resistance, and make the entire device run at minimal loss.

3. Conversion energy system

There is a built -in motor in the flywheel energy storage device, which is both an electric motor and a generator. When charging, it accelerates the flywheel as an electric motor; when discharge, it is powered by the generator to power the peripherals. At this time, the speed of the flywheel continues to decline; when the flywheel is idle, the entire device runs at minimal loss.
