Research on Efficiency Characteristics of Two Vehicle Braking Energy Recovery Methods

Currently,there are many braking energy recovery methods.Studying the efficiencies of these methods for different purposes is of great significance in terms of energy saving and environmental protection.In order to carry out the comparative study of efficiencies of the two braking energy recovery methods(i.e.Battery Energy Storage Method and Scroll Spring Energy Storage Method)in the field of vehicle ventilation,a device that can be used to intuitively compare the efficiencies of these two methods was developed.Mathematical models of this device for the two energy recovery methods were established respectively.In addition,Simulink was adopted to simulate the mathematical models,in order to learn about the effects of different parameters of the scroll spring and initial velocity of flywheel on energy recovery efficiency.This can provide some reference for choosing similar braking devices in the future and carrying out comparative study of simulation results,so as to choose the proper scroll spring type and obtain the theoretical efficiency of mechanical energy recovery.Then,the experimental device was tested to obtain the actual efficiency of mechanical energy recovery,which was compared to the theoretical value.The results showed that in the field of vehicle ventilation,compared to Battery Energy Storage Method,Scroll Spring Energy Storage Method can recover braking energy more efficiently and deserves more promotion.
