The performance test of four different martial lead acid (Li-Acid), Nickel cadmium (Ni-Cd), lithium-ion (Li-Ion) and nickel metal hydride (NiMH) batteries for 4WD electric vehicle under several speeds variation constraints are presented in this paper. The battery materials model choice is a key item, and thanks to an increasing importance on vehicle range and performance, the Li-Acid, Ni-Cd,Li-Ion and NiMH batteries could become a viable candidate that’s our proposal battery model in the present work , in this way the present paper show a novel strategy of 4WD electrical vehicle power electronics studies when the current battery take into account the impact of the direct torque based space vector modulation technique (DTC-SVM) in the several speed variations using the primitive battery SOC of 75 % state. The speed of four wheels is calculated independently during the turning with the electronic differential system computations which distributes torque and power to each in-wheel motor according to the requirements, adapts the speed of each motor to the driving conditions This paper focuses lead acid ,Lithium-ion and NiMH Batteries controlled by Buck Boost DC-DC converter power supply for EV. The performances of the proposed strategy controller give a satisfactory simulation results. The proposed control law increases the utility EV autonomous under several roads topologies.
