Design and simulation of the power-train system for an electric vehicle

During electric vehicle development process, a new methodology of power train parameters matching is established, which is based on theoretical calculation and engineering analysis. By setting up a co-simulation platform of AVL-cruise and Simulink, a regenerative braking control strategy is adopted to simulate and verify the designed EV power system. The simulation results with chosen driving cycles demonstrate that parameters matching of the whole vehicle power-train are reasonable and can meet the design specification of vehicle dynamic performance and driving range capability.
