Exhaustive Modeling of Electric Vehicle Dynamics, Powertrain and Energy Storage/Conversion for Electrical Component Sizing and Diagnostic
Abstract
Electric Vehicles (EVs) will play a major role in meetings Europe’s need for clean and efficient mobility. The development of new simulation tools, functionalities and methods integrated with the controlled development of a vehicle-centralized controller will also be part of the future solutions for the next generation of EVs. To improve the safety analysis and reduction costs, the solutions will be based on flexible user-friendly interfaces and specialized software tools. This work presents an exhaustive modeling of EV dynamics, powertrain and energy storage/conversion. The simulation model is useful for both electrical component sizing at designed time and on-board diagnostic to check component aging. The aim is to model the transient response of the system while preserving the simplicity and feasibility of simulation. The design of an EV requires, among others, the development and optimization of a complete electric powertrain system, including the longitudinal car, battery system components, power electronics, electric machine and control system. The paper presents the modelling and implementation of an entire powertrain system of EVs to describe the EV dynamics with respect to mechanical and electrical system components. Mathematical models based on equations and equivalent circuits are developed and implemented in MATLAB-Simulink and further study for predicting the final vehicle driving performance is performed.
