Analysis And Strategy Research On Braking Energy Recovery Of Hybrid Electric Vehicle

Environmental protection and energy conservation are the major issues facing mankind in today's and future economic and social development.New energy vehicles such as electric vehicles,hybrid electric vehicles as a replacement for traditional internal combustion engine vehicle,in the aspect of energy utilization efficiency and reduce emissions have the incomparable advantage,and can effectively meet the automotive emissions regulations.Braking energy recovery is one of the most important technologies for improving fuel economy and driving range of modern electric vehicles and hybrid vehicles.Using the braking energy recovery technology,through recycling the energy which is lost in the process of braking,then stored for battery recycling,to increase the range of new energy vehicle performance has important significance.This topic selected hybrid cars as the research object,through the theoretical analysis of hybrid vehicle braking energy recovery system strategy choice,the structure and principle of the braking energy recovery system are introduced.On the basis of establishing the dynamic model of braking system,the force of the braking process is analyzed and the driving equation of the brake is obtained.Then,the simulation software ADVISOR is used to build the vehicle model.According to the simulation test parameters of the vehicle,it is assumed that the braking energy recovery effect is evaluated under normal driving conditions of the city.In the end,the technical difficulties and deficiencies in the research are summarized and prospected.
