DESIGN AND DEVELOPMENT OF A HIGH-EFFICIENCY WIRELESS FAST CHARGING SYSTEM FOR URBAN MODES OF AUTONOMOUS ELECTRIC MOBILITY AND TRANSPORTATION

城市自主电动交通（e-mobility）和电动公共交通正在迅速实现。它们是人口众多的大都市的迫切需要。此外，城市公共交通（公共汽车、地铁和有轨电车）以及其他城市交通方式是城市面临的主要挑战。在世界上一些过度拥挤的城市中，现有的城市交通系统根本不够用。有害气体排放、事故、棘手的拥堵和计划外运营只是造成全球交通混乱的几个关键问题之一。自动驾驶和无人驾驶的电动汽车肯定会减轻这种干扰。这些新的城市电动交通模式将是智能的，没有人为错误。建立可持续和高效的自动移动基础设施的关键因素肯定包括电气化交通。由高能电池或大功率超级电容器供电的城市自动电动交通和大规模电动交通的机会性静态充电和动态、动态充电将是当前的需求。新颖的电力电子转换系统和创新的线圈设计将在将高能/大功率电力存储系统连接到充电基础设施方面发挥重要作用。******拟议的NSERC DG计划专门全面解决上述问题，重点是设计通用的、广泛的无线快速充电基础设施。静态（机会充电）和动态（动态充电）系统都将被设计、开发、测试和验证。无线功率传输（WPT）基本上可以分为两种方法：感应功率传输（IPT）和电容功率传输（CPT）。IPT是更成熟的方法，而CPT是一种新兴的方法，目前仅适用于低功率水平（高达1.0 kW）。拟议的NSERC DG计划旨在解决推进两种WPT方法的最先进技术的几个关键挑战。该提案的具体重点是高功率，高效率的静态和动态快速充电，用于未来城市自动电动交通和从电动自行车到电动公交车的大规模电动交通模式。WPT充电器的额定功率范围从1.0千瓦到50.0千瓦将被调查。整个方案分为6个主要任务：1)IPT磁性（线圈）设计；2)新型WPT电力电子变换器设计；3)高级WPT控制器开发；4)动态（动态）机会快速充电器（50kw）设计；5) CPT电容设计；IPT/CPT混合设计；6)电磁干扰屏蔽。******以上独家的研究对象使所提出的方案特别独特和专业化。这项研究肯定会导致未来的进步，更具体地说，是在自动电动交通/电动交通基础设施的整体效率和性能改进方面

Urban autonomous electric mobility (e-mobility) and electric mass transit are being realized quickly. They are the dire need for populous metropolitan cities. In addition, urban mass transit (buses, subways, and trams), among other modes of urban transportation, are a major challenge facing cities. In several overcrowded cities around the world, existing urban mobility systems are simply inadequate. Harmful emissions, accidents, knotty congestions, and unscheduled operations are just among the critical few issues that are creating transportation chaos worldwide. Autonomous and driverless e-mobility will certainly alleviate such disruptions. These new modes of urban e-mobility will be smart and free of human error. The key ingredient to build a sustainable and efficient autonomous mobility infrastructure will most certainly include electrified transportation. Opportunistic static charging and dynamic, in-motion charging of urban autonomous e-mobility and mass e-transport, powered either by high-energy batteries or high-power ultracapacitors, will be the need of the hour. Novel power electronic conversion systems and innovative coil designs will play a major role in interfacing high-energy/high-power electric storage systems to the charging infrastructure.******The proposed NSERC DG program specifically address the above issues comprehensively, focusing on the design of universal, wide-ranging wireless fast charging infrastructures. Both static (opportunity charging) as well as in-motion (dynamic charging) systems will be designed, developed, tested, and verified. Wireless Power Transfer (WPT) can be essentially classified into two methodologies: Inductive Power Transfer (IPT) and Capacitive Power Transfer (CPT). IPT is the more established method, while CPT is an emerging approach, catering solely to low-power levels at the moment (up to 1.0 kW). The proposed NSERC DG program will aim to address several key challenges in advancing the state-of-the-art for both WPT methods. The specific focus of this proposal is high power, high-efficiency static and in-motion fast charging for future modes of urban autonomous e-mobility and mass electric transportation from e-bikes to e-buses. WPT charger ratings ranging from 1.0 kW to 50.0 kW will be investigated. The overall program is divided in to 6 major tasks: 1) IPT magnetics (coil) design; 2) Novel WPT power electronic converter designs; 3) Advanced WPT controller development; 4) Design of an in-motion (dynamic) opportunity fast charger (50 kW); 5) Capacitance design for CPT; hybrid IPT/CPT design; and 6) EMI shielding.******The above exclusive research targets make the proposed program particularly unique and specialized. This research will most definitely lead to future progress, more specifically, with regards to overall efficiency and performance improvement of autonomous e-mobility/e-transportation infrastructure.**
