One of the important realities which would facilitate widespread adoption of next generation of plug-in electric vehicles is the capability of traveling long distances. Since nearly all residences and businesses are already equipped with a 120VAC mains connection, and most with a 240VAC connection, it is assumed that the majority of vehicle charging will take place when the vehicle is parked either overnight at home or during the daytime at the office. The drawback to this paradigm is that level-1 and level-2 charging can take anywhere from 4 to 20 hours depending on available power and battery size; meaning that trips of any substantial distance would involve some amount of planning and vehicle down-time. The current alternative is high power level-3 off-board charging. Off-board chargers are bulky, costly to manufacture, expensive to install, and are not practical without the evolution of a comprehensive national charging infrastructure. This Grant Opportunity for Academic Liaison with Industry (GOALI) project addresses design of an integrated universal on-board fast charger, compatible with level-1, level-2, and level-3 charging capabilities. In addition, the research team will ensure the highest quality integrated education and research to meet the emerging workforce and educational needs of the U.S. energy and transportation industries by educating young and talented graduate, undergraduate, and high school students.The objective of this project is to design, control, develop, and validate a universal onboard Silicon Carbide based high-power motor-integrated inverter/charger for electric vehicles. The underlying foundation behind this project is to provide a transformative solution to overcome present limitations of the charging methods, which integrates different disciplines such as electrical engineering and mechanical engineering, thus fostering multidisciplinary collaborative research. This important work will (1) lead to theoretical advancements in the design of onboard high-power chargers and introduce unique control strategies to prevent torque generation during three-phase charging; (2) result in innovative packaging and thermal management methods as well as physics of failure mode analyses for wide band gap based converters, leading to increased efficiency with lower size, weight, and cost; and (3) involve interdisciplinary research in power electronics, control, adjustable speed drives, packaging, reliability assessment, and thermal management.

促进下一代插电式电动汽车广泛采用的重要现实之一是长距离行驶的能力。由于几乎所有的住宅和企业都已经配备了120 VAC电源连接，并且大多数都配备了240 VAC连接，因此假设大多数车辆充电将在车辆停放在家中过夜或白天在办公室时进行。这种模式的缺点是，1级和2级充电可能需要4到20小时，这取决于可用的电力和电池大小;这意味着任何长距离的旅行都将涉及一些计划和车辆停机时间。目前的替代方案是高功率3级非车载充电。非车载充电器体积庞大，制造成本高，安装成本高，如果没有全面的国家充电基础设施，就不实用。这个学术界与工业界联络（GOALI）项目的资助机会旨在设计一个集成的通用车载快速充电器，兼容1级，2级和3级充电能力。此外，研究团队将确保最高质量的综合教育和研究，以满足美国能源和运输行业的新兴劳动力和教育需求，通过教育年轻和有才华的研究生，本科生和高中生。该项目的目标是设计，控制，开发，并验证了一个通用的车载碳化硅为基础的大功率电机集成逆变器/充电器的电动汽车。该项目背后的基础是提供一种变革性的解决方案，以克服目前充电方法的局限性，该解决方案整合了电气工程和机械工程等不同学科，从而促进多学科的合作研究。这项重要的工作将（1）导致车载大功率充电器设计的理论进步，并引入独特的控制策略以防止三相充电期间产生扭矩;（2）导致创新的封装和热管理方法以及宽带隙转换器的故障模式分析的物理学，从而以更小的尺寸、重量和成本提高效率;以及（3）涉及电力电子、控制、可调速驱动器、封装、可靠性评估和热管理的跨学科研究。
