Both the models manage a lot of input variables and take into account all the thermophysical aspects regulating the heat exchange phenomena between the battery and engine devices and the cooling medium used to maintain their thermal control. The main objective of the research is to design the two models and integrate them in the simulation tool used by Chrysler to predict the performance of hybrid vehicles in the early design stages. After that, using the battery cooling system model, a sensitivity study is performed to understand which are the most important factor affecting the thermal behaviour of the battery cells. Finally, a validation phase is conducted for both the software to guarantee the validity of their results. iv DEDICATION To my grandma, who always believed in me. v ACKNOWLEDGEMENTS This work is the result of the cooperation of two universities, the Politecnico di Torino and the University of Windsor, and two companies, FIAT and Chrysler, and it is thanks to the precious guidance of many people from all these institutions that this thesis has been developed. Firstly, I would like to express my deepest gratitude to my FIAT tutor Dr. Vittorio Ravello, who always gave me professional and moral support during the whole project. I am also profoundly grateful to Prof. Andrea Tonoli and Prof. Alberto Tenconi, from the Politecnico di Torino, for all their help and suggestions. Then, I would like to thank my advisors Dr. Peter Frise and Dr. Narayan Kar from the University of Windsor, for their important assistance both during the academic year and during the writing of the thesis. Moreover, I am particularly grateful to Jan Stewart and Mike Houston, for their patience and their continuous support. Furthermore, I would like to express my deepest gratitude to all the people who assisted me in Chrysler, starting from my tutors Oliver Gross and Mengyang Zhang, who always helped me during the internship period and allowed me to live a fantastic professional experience in Auburn Hills. Special thanks go also to my Chrysler supervisor Mohammed Malik and to all the colleagues I worked with, for their guidance and suggestions: Craig, Sachin, Joydip, Carrie, Tony, Witt, Joel, Rene, Julie and Lucille. Last but not least, I am profoundly grateful to Prof. Giovanni Belingardi from Politecnico di Torino and Dr. Edoardo Rabino from FIAT, for their precious advices. The most important thanks are reserved to my fantastic parents and brother, to my adorable girlfriend Martina and to my friends Andrea, Maurizio, Gianmarco, Carlo and Yupeng, who made this experience wonderful and unforgettable. vi LIST OF CONTENTS DECLARATION OF ORIGINALITY .............................................................................. iii ABSTRACT ....................................................................................................................... iv DEDICATION ..................................................................................................................... v ACKNOWLEDGEMENTS ............................................................................................... vi LIST OF TABLES ............................................................................................................. xv LIST OF FIGURES ........................................................................................................ xvii NOMENCLATURE ...................................................................................................... xxiii ABBREVIATIONS ....................................................................................................... xxix 1 INTRODUCTION ........................................................................................................... 1 1.1 Objectives ................................................................................................................... 2 1.2 Thesis organization .................................................................................................... 3 2 LITERATURE REVIEW .............................................................................................. 5 2.1 Latest developments in the worldwide automotive scenario...................................... 5 2.1.1 Environmental effects of fossil fuels ................................................................... 5 2.1.2 Sustainable transportation solutions .................................................................... 7 2.2 Innovative features introduced by vehicle hybridization ........................................... 9 2.2.1 Fuel consumption and emission levels reductions ............................................ 10 2.2.2 Environmental impact of hybrid car batteries ................................................... 10 2.3 Hybrid drivetrains .................................................................................................... 11 2.3.1 General concepts about hybrid vehicle drivetrains ............................................ 11 2.3.2 Parallel configuration......................................................................................... 12 2.3.2.1 Parallel hybrid strengths ............................................................................. 14 2.3.2.2 Description of the integrated starter generator ............................................ 14 vii 2.3.3 Series configuration ........................................................................................... 16 2.3.3.1 Series hybrid strengths ................................................................................ 18 2.3.4 Series-parallel configuration .............................................................................. 19 2.3.4.1 The Toyota
