Crash Safety of High-Voltage Powertrain Based Electric Vehicles: Electric Shock Risk Prevention (Springer Theses)

"This book systematically introduces fast winding-based discharge strategies used for permanent magnet synchronous machine-based drives in electric vehicles (EVs) after a crash. The contents are from the author's final thesis securing his Ph.D. degree. The book contains seven chapters. Chapter 1 introduces the motivation of the research. Chapter 2 reviews five types of injury hazards that the occupants might suffer during crashes, addressing the high-voltage problem. In Chapters 3, 4, and 5, different winding-based discharge techniques are developed. Chapter 6 discusses the general principles for selecting an effective and efficient discharge technique for a particular EV. The conclusion is drawn in Chapter 7. Some author's achievements are listed at the end of the book. This book introduces professional knowledge about the subject of electrical engineering. It can be used as a reference book for technicians and scholars in this area."-- Back cover Declaration Supervisor’s Foreword Abstract List of Publications Acknowledgements Contents Abbreviations Nomenclature List of Figures List of Tables List of Accompanying Materials 1 Introduction 1.1 Motivation 1.2 Dissertation Outline 2 Review of EV Safety in Crash Conditions 2.1 Injury Hazards to Occupants During Crash 2.1.1 Physical Hazards 2.1.2 Electric Shock Hazards 2.1.3 Corrosion, Intoxication and Burn Hazards 2.2 Regulatory Activities Concerning Crash 2.2.1 Regulations Concerning Physical Hazards 2.2.2 Regulations Concerning Electrical Hazards 2.2.3 Discussion and Future Challenges About Regulations 2.3 Technologies for Reducing Injury Hazards to Occupants After EV Crashes 2.3.1 Technologies for Reducing Physical Hazards 2.3.2 Technologies for Reducing Electric Shock Hazards 2.3.3 Technologies for Reducing RESS-Related Hazards 2.4 Valuable Topic Requiring Further Study 2.5 Summary 3 New Winding-Based Discharge Strategy for EV Powertrains with Extreme Parameters 3.1 Introduction 3.2 EFM and Mechanism of Winding-Based Discharge Methods 3.2.1 Energy Flow Model 3.2.2 Mechanism of Winding-Based Discharge Methods 3.3 Winding-Based Discharge Strategies for Systems with Extreme Parameters 3.3.1 Analysis of Traditional LDA-CI and Classic NDNQ Methods 3.3.2 Proposed Winding-Based Discharge Method 3.4 Experimental Results 3.5 Summary 4 Hybrid DC-Bus Capacitor Discharge Strategy for EV Powertrains with Highly Extreme Parameters 4.1 Introduction 4.2 Mechanism and Defects of Bleeder-Based Discharge Method 4.2.1 Mechanism and BR for Standstill Cases 4.2.2 Mechanism and BR for Running Case 4.2.3 Evaluation of Size and Weight Sacrifice 4.3 Proposed Hybrid Discharge Technique 4.3.1 Design of BR for Proposed Discharge Method 4.3.2 Discharge Modes and Control Algorithms 4.4 Experimental Verifications 4.5 Summary 5 Fault-Tolerant Winding-Based DC-Bus Capacitor Discharge Strategy 5.1 Introduction 5.2 Design of HSPO Based on SM Theory 5.2.1 Machine Modelling 5.2.2 Traditional SOSM Observer 5.2.3 Proposed Enhanced SOSM Observer 5.3 Design of Adaptive SW-LSPO 5.3.1 Traditional SW HF Injection Method 5.3.2 Impact of Bus Voltage on Sine-Wave HF Injection Method 5.3.3 Proposed Adaptive SW-LSPO 5.4 Fault-Tolerant Full-Speed Range Discharge 5.5 Simulation and Experimental Verifications 5.5.1 Simulation Results 5.5.2 Experimental Results 5.6 Summary 6 Winding-Based Discharge Technique Selection Rules Based on Parametric Analysis 6.1 Introduction 6.2 Selection Principles for NDZQ Method 6.2.1 Instant Discharge Occasions 6.2.2 Long-Cycle Discharge Occasions 6.2.3 Implementation Procedures of Selection Rules for NDZQ Methods 6.3 Selection Principles for Piecewise NDNQ Method 6.3.1 Criteria for Piecewise NDNQ Method Selection 6.3.2 Implementation Procedures 6.3.3 Overall Discharge Technique Selection Rules 6.4 Case Studies and Results 6.4.1 Verifications of Winding-Based Discharge Method Selection Rules 6.4.2 Judgement for Discharge Methods in Previous Chapters 6.5 Summary 7 Conclusions and Future Work 7.1 Conclusions 7.2 Future Work Appendix 1.
