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.
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.
Some advanced technologies like “serial 2 control strategy” , centralized storage system , and regenerative downshift have been have proven to recover brake braking energy efficiently. Because of dense traffic lights in cities, vehicles brake and start up frequently, which results in considerable energy consumption.
Generally, the method of braking energy recovery can be classified into two categories: electrical control strategy and mechanical energy harvesting approach. Electrical control strategy for braking energy recovery has been considered in EVs and hybrid electric vehicles (HEVs).
Therefore, the design and sizing of these systems (and of regenerative braking systems themselves) are influenced by the adopted storage technology, especially for on-board applications where the installation of energy storage systems is limited by interoperability issues and by weight and encumbrance constraints. 1.3.
First, the sensor detects the position at which the brake pedal is pressed to judge the braking demand. After calculating and controlling the energy management system, the total torque provided by the energy management system and the braking system will be equal to the torque that the braking system would have provided before.
