This study presents a complex electromechanical model for the simulation of a hybrid electric vehicle which is the Toyota Prius THS‐II. The electromechanical model comprises the electrical subsystem, as it is developed and adopted in the past in several research activities, however, the interest in this study is focused on the application of a mathematical model for the power split device (planetary gearbox) of the mechanical subsystem in order to take into account full dynamic interaction between the subsystems by taking into account gear dynamics, in comparison with previous studies which implement simple algebraic models. The differential equations of the mechanical subsystem are solved with the aid of a dimensionless system in order to deal with the ‘stiffness’ problem. The relevant simulations which have been performed considered two cases. In the first case, the power split device is modelled with a simple algebraic model, while in the second case, the mathematical model for the power split device is the model discussed in this study. The developed source code is compiled by employing the MPI module in order to render the relevant simulations capable of running very fast. Finally, a comparison between the results of the two cases is demonstrated.
