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

城市自主电力移动(e-Mobility)和电力公共交通正在快速实现。它们是人口稠密的大都市的迫切需求。此外，在其他城市交通方式中，城市公共交通(公共汽车、地铁和有轨电车)是城市面临的主要挑战。在世界上几个过度拥挤的城市，现有的城市交通系统根本不够用。有害排放、事故、棘手的拥堵和计划外作业只是造成全球交通混乱的为数不多的关键问题之一。自主和无人驾驶的电子移动肯定会缓解这种干扰。这些城市电子移动的新模式将是智能的，没有人为错误。建设可持续和高效的自主移动基础设施的关键因素肯定包括电气化交通。由高能电池或高功率超级电容器供电的城市自主电子移动和大众电子交通的机会主义静态充电和动态动态充电将是当务之急。新的电力电子转换系统和创新的线圈设计将在高能/高功率电力存储系统与充电基础设施的接口方面发挥重要作用。 拟议的NSERC DG计划专门针对上述问题进行全面解决，重点设计通用、范围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)系统都将进行设计、开发、测试和验证。无线电能传输(WPT)基本上可以分为两种方法：感应电能传输(IPT)和电容电能传输(CPT)。IPT是更成熟的方法，而CPT是一种新兴的方法，目前只满足低功率水平(最高1.0kW)。拟议的NSERC DG计划将致力于解决在推进这两种WPT方法的最先进技术方面的几个关键挑战。这项建议的具体重点是为未来城市自主电子移动和从电动自行车到电动公交车的大规模电动交通模式提供大功率、高效的静态和动态快速充电。将调查范围从1.0 kW到50.0 kW的WPT充电器额定值。整个计划分为6个主要任务：1)IPT磁体(线圈)设计；2)新型WPT电力电子转换器设计；3)先进WPT控制器开发；4)动态(动态)机会快速充电器设计(50 KW)；5)CPT电容设计；IPT/CPT混合设计；以及6)EMI屏蔽。 上述独家研究目标使拟议的计划特别独特和专门。这项研究肯定会导致未来的进展，更具体地说，就自主电子移动/电子交通基础设施的整体效率和性能改进而言。

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.
