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.

该PFI：空气技术翻译项目致力于翻译集成的双向板载充电器和DC/DC转换器技术，以满足插件电动汽车的紧凑和高效电动转换器的需求。提出的技术很重要，因为它减少了车载转换器的重量，体积和成本，同时提高其效率并启用双向操作。该项目的成功完成将有助于广泛采用电动汽车，一旦技术逐渐朝着商业化迈进，就可以通过小型企业合作伙伴来创造就业机会。该项目将导致电动汽车集成充电器/转换器的原型。该转换器在当前选项上具有以下独特功能：双向操作，整个充电期内较高的效率，较少的组件以及空冷的热管理系统。这些功能提供了增强功效，更大的功率密度和可观的成本节省的优势，与在当前市场领域中使用单个充电器和单个辅助负载转换器的竞争常规方法相比。 该项目解决了以下技术差距，因为它从研究发现转化为商业应用：（1）超紧凑，集成的车辆到网格（V2G）和车辆对车辆（G2V）充电器和转换器的设计和开发方面的理论进步； （2）基于宽带的碳化物（SIC）功率电子转换器的创新热管理方法； （3）演示用于插电式电动汽车的功能原型集成充电器/转换器，（4）评估和原型针对常规技术的商业有价值的转换器的商业有价值的解决方案，以及（5）制定超越该项目的商业化策略。此外，参与该项目的人员，PI，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经验。这将通过从可行性到原型阶段的设计和包装活动来实现。该项目吸引了马里兰州大学和Genovation Cars Inc.的研究人员，以设计，开发和验证从研究发现到商业现实的这种技术翻译工作的原型。
