此PFI：空气技术转换项目专注于转换集成的双向车载充电器和DC/DC转换器技术，以满足插电式电动汽车对紧凑型和高效电源转换器的需求。这项建议的技术非常重要，因为它降低了板载转换器的重量、体积和成本，同时提高了它们的效率，并实现了双向操作。该项目的成功完成将促进电动汽车的广泛采用，并在技术成熟走向商业化后，通过小企业合作伙伴创造就业机会。该项目将产生一个电动汽车集成充电器/转换器的原型。与现有的选件相比，该转换器具有以下独特功能：双向运行、整个充电期效率更高、组件数量更少以及风冷式热管理系统。与当前市场空间中使用单个充电器和单个辅助负载转换器的竞争传统方法相比，这些功能提供了更高的效率、更大的功率密度和相当大的成本节约。该项目在从研究发现转化为商业应用的过程中解决了以下技术差距：(1)超紧凑、集成的车网(V2G)和电网(G2V)充电器和转换器的设计和开发方面的理论进展；(2)基于宽带隙碳化硅(SIC)的电力电子转换器的创新热管理方法；(3)插电式电动汽车集成充电器/转换器的功能原型演示；(4)相对于传统技术，评估和制作具有商业价值的转换器解决方案的原型；以及(5)制定该项目以外的商业化战略。此外，参与该项目的人员、绩效指标、本科生和毕业生将通过技术和商业化任务获得创新和技术翻译体验。这将通过从可行性到原型阶段的设计和包装活动来实现。该项目聘请了马里兰大学和Genvation Cars Inc.的研究人员来设计、开发和验证这项技术从研究发现到商业现实的转换工作的原型。

This PFI: AIR Technology Translation project focuses on translating an integrated bidirectional onboard charger and dc/dc converter technology to fill the need for compact and efficient power converters for plug-in electric vehicles. The proposed technology is important because it reduces the weight, volume and cost of onboard converters, while enhancing their efficiencies, and enabling bidirectional operation. The successful completion of this project will facilitate widespread adoption of electric vehicles, and lead to the creation of jobs through the small business partner once the technology matures toward commercialization. The project will result in a prototype of an integrated charger/converter for electric vehicles. This converter has the following unique features over current options: bidirectional operation, higher efficiency over entire charging period, less number of components, and an air-cooled thermal management system. These features provide the advantages of enhanced efficacy, greater power density, and considerable cost savings, in comparison to the competing conventional method of utilizing an individual charger and an individual auxiliary load converter in the current market space. This project addresses the following technology gaps as it translates from research discovery toward commercial application: (1) theoretical advancements in the design and development of ultra-compact, integrated vehicle-to-grid (V2G) and grid-to-vehicle (G2V) chargers and converters; (2) innovative thermal management methods for wide band-gap Silicon Carbide (SiC) based power electronic converters; (3) demonstration of a functional prototype integrated charger/converter for plug-in electric vehicles, (4) evaluation and prototyping a commercially valuable solution of proposed converter against conventional technologies, and (5) developing a strategy for commercialization beyond this project. In addition, personnel involved in this project, PIs, undergraduates and graduates will receive innovation and technology translation experiences through technical and commercialization tasks. This will be achieved through design and packaging activities from the feasibility to prototyping stage.The project engages researchers from University of Maryland and Genovation Cars Inc. to design, develop, and validate a prototype of this technology translation effort from research discovery toward commercial reality.
