Approaches in modeling electrical energy conversion systems in hybrid vehicles

Purpose. Selection of adequate software and development of a modeling methodology for economical multi-domain simulation of the power distribution and conversion system, taking into account the control system for modern vehicles, in particular, for a hybrid electric vehicle with a fuel cell (HEV). Methodology. The main research method is mathematical modeling; for the structural synthesis of the model of the power conversion system and comparative analysis of programs, heuristic decision-making methods based on the comparison of variant metrics were used. Findings. A method of decomposition of HEV from the point of view of the scope of application of existing programs for modeling its subsystems is proposed. Subsystems from blocks of such a structural scheme are suitable for research using single-domain modeling programs. The prospects of the computer-aided design in electronics (ECAD) programs for multi-domain HEV modeling are shown, since the central and main conversion unit is the electronic domain. Based on the selected software metrics, the choice of programs for modeling the power conversion system is justified, with the possibility of organizing model interfaces to ensure mu
