Abstract

The invention relates to the technical field of energy storage equipment and particularly relates to a flywheel energy storage device which comprises a motor, a first connecting assembly, a second connecting assembly, a flywheel and a vacuum box body. A rotating shaft of the motor is in transmission connection with the first connecting assembly, and the rotating shaft and the first connecting assembly are positioned outside the vacuum box body. The second connecting assembly and the flywheel are in transmission connection and are both located in the vacuum box body. The first connecting assembly and the second connecting assembly are oppositely arranged and can transmit torque to each other, and the vacuum box body and the motor are oppositely and fixedly arranged. The flywheel energy storage device provided by the invention has high energy storage efficiency, the problem that the motor is difficult to dissipate heat in a vacuum environment is relieved, the requirements for the performance of the motor can be reduced, the improvement of the energy storage capacity of the flywheel is facilitated, and also the meeting of customization demands is facilitated.

Description

technical field [0001] The invention relates to the technical field of energy storage equipment, in particular to a flywheel energy storage device. Background technique [0002] The flywheel energy storage system is a high-efficiency energy-saving inertial energy storage device, which uses an ultra-high-speed rotating flywheel to store energy, and realizes the mutual conversion of mechanical energy and electrical energy through an electromechanical energy conversion device. Based on its high specific energy, high specific power, high conversion efficiency between electrical energy and mechanical energy, fast charging, maintenance-free, and good performance-price ratio, it is widely used in electric vehicles, aerospace, power grid peak regulation, and wind power. Uninterrupted power supply of power generation systems and military fields have broad application prospects. [0003] However, in order to realize torque transmission, the flywheel rotor in the existing flywheel ene...
