Thus, elastic energy storage via spiral springs can improve the stability and controllability of power grid for supply and demand, improving the quality of power grid. It realizes energy transfer in time to meet the balance of energy supply and demand. Fig. 2.
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.
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.
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.
Elastic energy storage technology could also be combined with other energy conversion approaches based on the electromagnetic, piezoelectric principle which can present unique advantages and realize the multidisciplinary integration , , .
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].
