摘要:
The present invention relates to a storage system for storing energy useful in starting and regulating electrical systems, comprising transmission means (8) to transmit mechanical energy between an electric machine (9) and an energy storage device comprising at least one coil spring (1) arranged in a rotating shaft (4); a braking and holding element (5) connected to the shaft (4) to alternately block the spring (1) or keep it in a released situation in which the electric machine (9) acts like a motor turning the rotating shaft (4) in a first direction tensing the spring (1) to store mechanical energy, whereas the rotation of the shaft (4) in the opposite direction releases the mechanical energy stored in the spring (1) such that the transmission means turn the electric machine (9) so that it operates like an electric generator.
