Book Description
Electric vehicles (EVs) have signaled a new era in the transportation sector. One key area that is still in development and has a future scope for advancement is the efficient charging systems of the EVs. Due to safety limitations and the lack of charging infrastructure, most of EVs are opted with a two-stage on-board charger (OBC) that allows charging of battery packs from standard utility sockets (85-265 V) as per SAE J1772. Existing EVs such as Neighborhood Electric Vehicles (NEVs), Plug-in-hybrid Electric Vehicles (PHEVs), forklifts, golf kart, and buses have different operating voltages, power levels and vehicle ranges. The output voltage of the OBC falls under one of the three possible ranges, 36-72 V, 72-150 V, and 200-450 V, depending on the type of electric vehicle mentioned above. This thesis presents the design of a universal on-board charger that can address the wide range of battery pack voltages. In a two-stage OBC, this requirement is achieved by varying the AC/DC converter output voltage using the concept of variable DC link rather than fixed DC link in conventional converters. An interleaved boost cascaded-by-buck (IBCBB) power factor correction (PFC) converter has been proposed as an AC/DC converter. Small signal analysis of the converter for the design of the closed loop control structure is also presented. The design consideration for component selection in hardware implementation is also presented. A 1.0 kW system of proposed converter has been designed for proof-of concept. The detailed current stress analysis and loss modelling of the proposed converter was done using empirical calculations and verified using PSIM. To enhance the efficiency of the converter, a simple zero current switching (ZCS) method is applied to most operated boost switch to reduce the turn-off losses. The peak efficiency of 96.4% was observed on proposed soft switched converter. A 1.0 kW system for proof-of concept was implemented. To reduce the turn-on and turn-off losses of the converter and enhance the efficiency of converter further, a simple auxiliary resonant circuit has been implemented to most operated boost switch. This auxiliary circuit provides the zero voltage transition (ZVT) and zero current transition (ZCT) of the boost switch and the remaining components are also soft switched. The detailed timing waveforms of converter operation is presented. The peak efficiency of 97.4% is observed on a 1.0 kW proof-of-concept prototype. Finally, an existing zero voltage switching (ZVS) phase shifted DC-DC converter with the designed high frequency transformer is integrated to the proposed AC/DC converter for wide range of output voltages. Simulations of the overall system is presented and a proof-of-concept is also implemented.

Book Description
The increase in air pollution and vehicular emissions has led to the development of the renewable energy-based generation and electrification of transportation. Further, the electrification shift faces an enormous challenge due to limited driving range, long charging time, and high initial cost of deployment. Firstly, there has been a discussion on renewable energy such as how wind power and solar power can be generated by wind turbines and photovoltaics, respectively, while these are intermittent in nature. The combination of these renewable energy resources with available power generation system will make electric vehicle (EV) charging sustainable and viable after the payback period. Recently, there has also been a significant discussion focused on various EV charging types and the level of power for charging to minimize the charging time. By focusing on both sustainable and renewable energy, as well as charging infrastructures and technologies, the future for EV can be explored. Developing Charging Infrastructure and Technologies for Electric Vehicles reviews and discusses the state of the art in electric vehicle charging technologies, their applications, economic, environmental, and social impact, and integration with renewable energy. This book captures the state of the art in electric vehicle charging infrastructure deployment, their applications, architectures, and relevant technologies. In addition, this book identifies potential research directions and technologies that facilitate insights on EV charging in various charging places such as smart home charging, parking EV charging, and charging stations. This book will be essential for power system architects, mechanics, electrical engineers, practitioners, developers, practitioners, researchers, academicians, and students interested in the problems and solutions to the state-of-the-art status of electric vehicles.

Book Description
This book describes the fundamentals and applications of wireless power transfer (WPT) in electric vehicles (EVs). Wireless power transfer (WPT) is a technology that allows devices to be powered without having to be connected to the electrical grid by a cable. Electric vehicles can greatly benefit from WPT, as it does away with the need for users to manually recharge the vehicles’ batteries, leading to safer charging operations. Some wireless chargers are available already, and research is underway to develop even more efficient and practical chargers for EVs. This book brings readers up to date on the state-of-the-art worldwide. In particular, it provides: • The fundamental principles of WPT for the wireless charging of electric vehicles (car, bicycles and drones), including compensation topologies, bi-directionality and coil topologies. • Information on international standards for EV wireless charging. • Design procedures for EV wireless chargers, including software files to help readers test their own designs. • Guidelines on the components and materials for EV wireless chargers. • Review and analysis of the main control algorithms applied to EV wireless chargers. • Review and analysis of commercial EV wireless charger products coming to the market and the main research projects on this topic being carried out worldwide. The book provides essential practical guidance on how to design wireless chargers for electric vehicles, and supplies MATLAB files that demonstrate the complexities of WPT technology, and which can help readers design their own chargers.

Book Description
Market penetration of electric vehicles (EVs) is largely hindered by the lack of a nationwide fast charging network and limited drive range. The fast charging electric vehicle supply equipment (EVSE) is costly to implement on a large-scale due to the need for high power charging hardware comprising of multiple power electronic stages dedicated to delivering controlled power to the EV battery. This thesis proposes an integrated charge and drive system for EVs. The concept is to utilize the on-vehicle powertrain as the EVSE, thus offering a cost-effective solution by eliminating the DC/DC power conversion stage from the EVSE. The integrated system consists of two energy sources paired with drive inverters that are connected in series through an electric motor with a simple open-stator winding, where the charging input is accessed from the differential connection of the inverters. In comparison to previous fast charging integrated solutions that require the use of two power stages in the traction system to enable integrated charging, the proposed integrated solution only requires a single power stage in the traction drive. While the dual energy sources integrating hybrid energy storage media may consist of two identical battery packs, the powertrain can be further leveraged to potentially extend drive range. Charging and driving features of the integrated system are verified in simulation and experiment, through development of a 110kW motor drive test bench integrating dual energy sources of both similar and differing characteristics. The experimental results demonstrate feasibility of utilizing traction hardware to regulate the charging current under established constant-current and constant-voltage battery charging modes. A balancing control strategy is also developed to equalize the energy between the dual energy sources. For vehicle propulsion, the results demonstrate flexible power sharing between two energy sources under static dynamic driving conditions, where in the case of a battery and supercapacitor, power energy management of the supercapacitor is achieved without reliance on a two-stage power electronic solution. Numerical efficiency comparison between existing traction drives and the proposed traction drive shows up to 14% additional range from an electric vehicle using the proposed system in an urban setting.
