Vortex spring energy storage

What is Vortex Spring energy storage?

The vortex spring energy storage is a purely mechanical structure, which can realize the storage of elastic potential energy. Its processing and manufacturing are simple, maintenance is easy, and the cost is extremely low compared with other methods.

Can regenerative braking energy be stored through a Vortex Spring?

To sum up, this study aims to establish a storage and utilization system of regenerative braking energy through the vortex spring energy storage device using the retired components of the EMU train. So as to maximize the reduction of energy storage costs and maximize the use of regenerative braking energy.

What are the functions of elastic storage device using spiral spring?

The principal functions of elastic storage device using spiral spring are energy storage and transfer in space and time. Elastic energy storage using spiral spring can realize the balance between energy supply and demand in many applications.

What is spiral spring energy storage?

Spiral spring energy storage harvests and stores random mechanical energy. Harvesting and storing energy is a key problem in some applications. Elastic energy storage technology has the advantages of wide-sources, simple structural principle, renewability, high effectiveness and environmental-friendliness.

What is elastic energy storage – electric power generation system?

With the elastic energy storage–electric power generation system, grid electrical energy can drive electric motors to wind up a spiral spring group to store energy when power grid is adequate, and the stored energy can drive electric generators to generate electrical energy when power grid is insufficient. The working principle is shown in Fig. 2.

What causes energy loss in a vortex Reed box?

According to the description in [ 15 ], the energy loss of the energy storage mode of the vortex reed box mainly comes from the friction and resistance loss on the main shaft of the energy storage box and the friction and heat loss between the vortex springs. Both of these numerical ranges are within 5%.
