6 FAQs about [Elastic energy storage for electrical equipment]

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 is the most common elastic energy storage device?

Spiral spring is the most common elastic energy storage device in practical applications. Humanity has developed various types of elastic energy storage devices, such as helical springs, disc springs, leaf springs, and spiral springs, of which the spiral spring is the most frequently-used device. Spiral springs are wound from steel strips [19, 20].

What are the advantages of elastic energy storage devices?

Elastic energy storage devices store mechanic work input and release the stored energy to drive external loads. Elastic energy storage has the advantages of simple structural principle, high reliability, renewability, high-efficiency, and non-pollution , , .

What is electrical energy storage (EES)?

Electrical Energy Storage, EES, is one of the key technologies in the areas covered by the IEC. EES techniques have shown unique capabilities in coping with some critical characteristics of electricity, for example hourly variations in demand and price.

What is elastic energy storage?

Compared with the traditional chemical battery, elastic energy storage does not automatically release energy due to self-discharge, therefore the energy can be stored for a much longer time and can be repeatedly stored and released.

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.
