Analysis and simulation of regenerate braking of driving system for electrical vehicle

According to the energy requirements and extension of driving range. Electrical vehicle (EV) should have a capacity of regenerative braking. EV may not only provide braking force but also recycle the kinetic energy. This kinetic energy can be transformed in electrical energy and be take in battery of EV. 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. And simulation are explored and discussed. The result shows that the design of the mathematic system is feasible. It can meet the need of the kinetic energy.
