| Abstract: | This paper outlines the classical powertrain schemes of pure electric vehicles and points out the advantages and disadvantages of the powertrains. A novel powertrain scheme of pure electric vehicle based on dual-motor, dual-planetary transmission is proposed. The dynamics and kinematics equations of this new transmission are derived, and the equivalent lever diagram of the powertrain is established. The power performance requirements of the pure electric vehicle are worked out, and parameters of the powertrain components are matched. A forward vehicle model has been built based on Matlab/Simulink. The feasibility of the scheme is verified by the simulation on specific driving cycle. |
