PFI:AIR - TT: Integrated Bidirectional Power Electronic Charger/Converter for Plug-in Electric Vehicles

这个PFI: AIR技术翻译项目的重点是翻译一种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高效的电源转换器的需求。该技术非常重要，因为它减少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，一旦技术成熟走向商业化，将通过小型企业合作伙伴创造就业机会。该项目将产生用于电动汽车的集成充电器/转换器的原型。与目前的选择相比，该转换器具有以下独特功能：双向操作，整个充电期间效率更高，组件数量更少，以及风冷热管理系统。与目前市场上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，这些功能提供了增强的效率、更高的功率密度和可观的成本节约等优势。该项目解决了从研究发现到商业应用的以下技术差距：(1)在设计和开发超紧凑型集成车辆到电网（V2G）和电网到车辆（G2V）充电器和转换器方面的理论进步；(2)基于宽带隙碳化硅（SiC）的电力电子变换器的创新热管理方法；(3)展示用于插电式电动汽车的集成充电器/转换器的功能原型；(4)对拟议的转换器与传统技术的商业价值解决方案进行评估和原型设计；(5)制定超出本项目的商业化战略。此外，参与该项目的人员，pi，本科生和研究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。该项目邀请马里兰大学和genation Cars Inc.的研究人员设计、开发和验证这项技术的原型，将研究发现转化为商业现实。

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.
