Energy storage device for braking energy recovery

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.

What is regenerative braking energy recovery system?

The actual vehicle test device is built and the actual road vehicle tests are carried out. The regenerative braking energy recovery system of pure electric vehicle is to recover and reuse the consumed driving energy under the premise of ensuring the braking safety.

What is electric energy recovery module?

The electric energy recovery module uses a certain control strategy to recover the braking energy into the vehicle battery. The control module is used to control the entire system, recycle the braking energy, and select the suitable energy recovery pathway under different braking modes, such as inching braking and emergency braking. 2.1.

What is braking energy recovery management strategy?

In real-world applications, a suitable braking energy recovery management strategy needs to be selected and optimized according to the vehicle power source, driving conditions and braking performance, in order to obtain good vehicle braking performance and energy economy. 2. Modeling of regenerative braking energy recovery systems

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
