1. During system energy storage, the motor operates as an electric motor, receiving electrical energy from the grid via a power electronic converter to accelerate the motor. The motor then drives the flywheel to accelerate and store energy, with the energy being stored as kinetic energy in the high-speed rotating flywheel. 2. When the flywheel reaches the preset maximum speed, the system enters an energy retention state. Upon receiving a control signal to release energy, the system discharges energy. The high-speed rotating flywheel utilizes its inertia to drive the motor to decelerate and generate electricity. The power converter then outputs electrical energy suitable for the load requirements, completing the conversion from kinetic energy to electrical energy.

What is the solution for Accord brake noise?

Accord brake noise solution is: remove the brake pads, grind the 90-degree straight edges into beveled edges, and the noise will be significantly reduced, or replace them with better quality brake pads. Brake pads, also known as brake linings, are critical safety components in a car's braking system. The effectiveness of all braking is decisively influenced by the brake pads. Brake pads (brake lining) are generally composed of a steel plate, an adhesive heat insulation layer, and a friction block. The steel plate is coated to prevent rust, and the coating process is monitored using an SMT4 furnace temperature tracker to ensure the temperature distribution during coating meets quality standards. The heat insulation layer is made of non-heat-conducting materials to provide thermal insulation. In terms of body dimensions, the Accord measures 4893mm in length, 1862mm in width, and 1449mm in height.
