Research On Strategy And Simulation Control Of Pure Electric Vehicle’s Regenerative Braking

Car was born one hundred years. Now il has become ihe most popular means ol’ transporlation in people’s daily life and occupies an important position. But with the continually increasing of world’s automobile product ion and holdings, the automotive industry’s dependence on oil and other fossil energy and the environmental damage that has been caused, have also attraded attention. In addition, it was reported thai of oil resources will be depleted in30-40years ealculated by the world’s proven oil reserves and the annual consumption. Currently, China’s aulomobi lc industry is facing the dual pressures of environmental protect ion and energy saving. Kloctric cars can use sonsumption of the eleelrical energy to drive and energy can be obtainod through other forms of energy. Recovering and reevering the and omotive brakiug energy, can improve, the utilization of car’.s energy. Nowadays il is also becoming the hot issues in exploring the electric car technology,This article describes the basie prineiple of the car regenerative braking system, and analyzes the braking force and the process of energy conversion for the car regenerative braking system. We set up a domestic model of pure electric car as research object, and presenter the car regenerative braking system control strategy, and then use Matlab/Siinulink software and Advisor software to build the simulation model for the pure electrie car regenerative braking system. To do the simulation analysis for the pure electric cat-regenerative braking control process under ECE and1015working conditions and then to judge the simulation results based on a variety of evaluation of the car’s regenerative braking control strategy, finally, to present the new improvement program according to the evaluation esults, that increasing efficiency of the energy recovery for the car regenerative braking system effectively.
