Abstract

The invention discloses a flywheel energy storage device without a gyroscopic effect. The device comprises a support capable of providing three rotational degrees of freedom, two flywheel batteries which are coaxially and oppositely arranged in the same direction and a flywheel power control system, the state of the support capable of providing three rotational degrees of freedom is monitored through a sensor, and when it is found that the degrees of freedom are about to coincide, the power difference of the two flywheels is adjusted, so that the three-degree-of-freedom function of the supportis available at any time. The system is suitable for occasions such as electric vehicles and engineering vehicles.

Description

technical field [0001] The invention generally relates to a flywheel energy storage device, in particular to a large-scale energy storage device without gyro effect. Background technique [0002] The application of large-mass flywheel batteries in automobiles will increase the bearing load and generate torque on the body due to the gyroscopic effect. During the charging and discharging of the vehicle and the bumpy turning of the vehicle, the battery will generate excess torque to the outside, which will affect the driving stability of the vehicle, and will generate a large load on the flywheel battery shaft. The magnetic suspension bearing has limited stiffness, and the load will increase the power consumption; [0003] In the field of energy storage applications, the flywheel rotor is driven by an electric / generator reversible motor to rotate at high speed, and the electric energy is stored in the form of inertial mechanical rotational kinetic energy—that is, "charging"; co...
