The third category deals with the design and introduction of new systems such as permanent-magnet synchronous machines (PMSMs), batteries or ultra-capacitors storage systems etc.Ī lot of useful work has been done in the past with respect to the three major categories. The second category deals with the Energy Management Strategy of an HEV in order to satisfy the driver's power demand and maximise at the same time fuel's economy. battery models, vehicle dynamic models, converter models, etc.). The first category deals with the improvement of the mathematical models used to study and improve the performance of critical subsystems of an HEV (i.e. The interest is divided into three major categories. Therefore, there is a global effort during the past 20 years to improve many parts of an HEV or to introduce new ones. Nevertheless, the HEV should be characterised by high performance in order to fulfil the driver's demands at the same time. The reason is the reduction of fuel consumption and reduction of gases emissions. There is an international interest with respect to hybrid electric vehicle (HEV) technology. Finally, a comparison between the results of the two cases is demonstrated.

The developed source code is compiled by employing the MPI module in order to render the relevant simulations capable of running very fast.
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 relevant simulations which have been performed considered two cases. 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 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. This study presents a complex electromechanical model for the simulation of a hybrid electric vehicle which is the Toyota Prius THS-II.
