Mission Profile-Oriented Design of Battery Systems for Electric Vehicles in MATLAB/Simulink

Due to the nonlinear characteristics of the battery cells and the non-static power demand of the electric vehicles (EV) during their mission profiles, the dynamic behavior of the system cannot be statically calculated and analyzed in course of the electrical design of the battery system (BS). In this paper, a simulation environment is presented as a tool for mission profileoriented electrical design and performance analysis of BS in drives of e-cars and e-aircrafts. This allows effective design and rapid verification of the system level requirements. The model design is submitted through the introduction of the operation with equations and simulation results in MATLAB/Simulink. The paper describes a case study, the model performance is investigated, where the New European Driving Cycle (NEDC) is taken as basis. The BS contains a battery pack (BP) of lithiumion cells with relatively high energyand power density.
