Research Of Pure Electric Vehicle Energy Feedback Control Strategy And Simulation

Energy and environmental issues have become the hot topic in today’s human, including car although is of vital importance in the development of economy, bring convenience to human life work, but fuel vehicles caused by environmental problems to be reckoned with. In order to be able to well solve the problem of energy shortage and environmental pollution, more and more countries research and development of new energy vehicles, including the advantages of pure electric vehicles with zero pollution is seriously. Pure electric vehicle power sources, wind power, hydro power, solar power can pass and nuclear power etc.The pure electric vehicles in addition to the environmental protection good advantage travel distance is short, high battery costs, the key technical problems of poor dynamic performance. Aiming at the problem of short trip range of pure electric vehicles with energy feedback of pure electric vehicle energy feedback control strategy is studied.Pure electric vehicle regenerative braking energy feedback is not only to concern motor with the traditional friction brake force distribution, but also ensure braking efficiency of both the driver’s braking sense.Energy feedback control strategy for the establishment of the goal is to recycle as much as possible amount of energy, improve the travel distance of the vehicle. To consider when making energy feedback control strategy of conditions such as the battery and motor power rating.This article simply introduced the composition structure of the energy feedback, the motor of renewable power generation principle and the influence factors of energy feedback.The ideal braking force are analyzed in this paper, the best braking energy recovery and braking energy recovery and the advantages and disadvantages of three kinds of control strategy in parallel, meet the conditions of effective energy feedback control strategy.Built in the MATLAB/simulink model of pure electric vehicles, including battery model, motor model, driver model and vehicle model, the model of setting the parameters of the model can reflect the real vehicle energy feedback situation, according to the article of energy feedback control strategy for the vehicle simulation, verify the analysis in this paper, the effect of the energy feedback control strategy.
