Energy storage brake pump

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 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.

How effective is braking energy recovery system?

Auxiliary starting torque of 12.7 N m, maximum voltage of 3.5 V and total energy recovery efficiencies of 0.53 can be obtained, verifying that the proposed braking energy recovery system is effective and beneficial for vehicle energy savings. 1. Introduction

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.

How does braking energy recovery affect battery life?

The efficiency of braking energy recovery, the speed control performance of FESS and battery life are increased. Braking energy recovery (BER) notably extends the range of electric vehicles (EVs), yet the high power it generates can diminish battery life.

Does braking energy harvesting save energy?

According to previous research, braking accounts for 7%–10% of the vehicle energy consumption , which indicates that braking energy harvesting strategy has a tremendous potential in energy savings.
