Study And Analysis On Regenerative Braking Energy Of The Electric Vehicle

Automobile industries have development of high speed in 20 century. Resource insobriety is consumed, excessive contamination are let out, which are direct and mostly causation of mention question. Electric vehicle are regard as one of the approach of solving two important questions. However, Dynamical performances of electric vehicle are decided by drive systems and extension of driving range (energy supply) restricts development, prevalence and is limit to electricity capacity of storage battery. In order to improve dynamical performances and extension of driving range, we must analyze and research traits of drive motor and control tactic of energy recycle in electric vehicle. ADVISOR software is one of widely applied software of vehicle simulation. So utilizing it may be rapid and true to modeling and simulation of the electric vehicle.This paper mostly research simulation technology of testing of dynamical performances in electric vehicle and evaluate technology regenerative braking in large capacitance capacitor. Via ADVISOR software testing obtain some targets of dynamical performances. In view of the analysis of braking mode, the permanent magnet brushless dc motor system is used to fulfill electrical braking with the control strategy during acting as power of EV. Regenerative braking results will be simulated in the computer. Afterward calculating numerical value of feedback energy. Setting out evaluate regenerative braking energy in large capacitance capacitor and electric vehicle's extension of driving range.Finally the paper will give some advices and expect.
