Elastic energy storage braking

How does electric energy storage work in a braking system?

Since the energy storage capacity of battery is much greater than the coil spring, the electric energy storage method always participates in energy recovery throughout the entire braking process. The total recycled energy (E sum 1) is the sum of the deformation energy of the coil spring and the feedback energy to the power battery.

What is elastic energy storage – electric power generation system?

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.

Is regenerative braking a promising energy recovery mechanism?

Regenerative braking system is a promising energy recovery mechanism to achieve energy saving in EVs (electric vehicles). This paper focuses on a novel mechanical and electrical dual-pathway braking energy recovery system (BERS) based on coil springs for energy saving applications in EVs.

Can regenerative braking energy be used for energy storage?

If in the way of recovering and utilizing regenerative braking energy, the retired components of EMU trains can be reasonably used to form an energy storage system together with a certain low-cost energy storage medium.

What is electro-mechanical braking energy recovery system?

An electro-mechanical braking energy recovery system is presented. Coil springs are used for harvesting the braking energy of a vehicle. The system can provide extra start-up torque for the vehicle. Efficiencies of 0.56 and 0.53 are obtained in the simulation and experiments.

How does regenerative braking work?

The regenerative braking system converts the kinetic energy of driving vehicles into elastic potential energy. This process can be modelled and simulated to identify the characteristics of the proposed regenerative braking system. Ignore the influence of wind resistance and heat dissipation on the energy collection efficiency of the system.
