Research on designing the regenerative braking system apply to conventional vehicle ☆

This study will calculate, design, and fabricate the inertial energy recovery model of the vehicle during braking or deceleration. This energy recovery unit is applicable to conventional vehicles, including a double planetary gear set is added in parallel with the propeller shaft; a generator is coaxial with the flywheel to convert the mechanical energy into electricity to recharge for battery. The simulation and experimental models are built and controlled in the FTP75; NEDC; EUDC and ECR15 driving cycles. When the vehicle's deceleration occurs, the energy recovery process is started. The control method based on regenerative energy optimization is used for both simulation and experimental models. Experimental results show that the recovered energy can reach from 22% to 38% of the inertia energy of the car during the vehicle deceleration. This energy is converted into electricity to be used for additional loads on the vehicle
