The broader impact/commercial potential of this project is to develop the first low-cost and integrated onboard charger and auxiliary power module for electric vehicles, facilitating deployment of next-generation electrified transportation systems. It is noteworthy that there are more than 250 million registered passenger vehicles in the U.S. Over 40% of greenhouse gases and 70% of emissions come from the transportation sector, and transportation is 99% dependent on one source of fuel: petroleum. Mainstream adoption of electric vehicles is essential if the U.S. is to gain energy security and substantially reduce carbon emissions. The electric car industry has passed its tipping point; however, electric vehicles are still in the very early stages of development. Like early computers, the pieces that make up an electric car are large, heavy, costly and unable to efficiently communicate amongst themselves. The proposed technology not only reduces the volume, cost, and weight of onboard chargers for electric vehicles, but also enhances their efficiencies, and enables bidirectional operation to support future Smart Grid functionalities. This project will lead to creating jobs once the technology matures toward commercialization.This Small Business Innovation Research (SBIR) Phase I project will lead to design and development of an innovative integrated and bidirectional onboard charger for electric vehicles. Currently, all the upcoming and commercially available electric vehicles are equipped with an individual onboard charger to charge traction batteries and an additional auxiliary power module to power auxiliary loads. These converters are heavy, bulky, costly and need to communicate over a variety of controller area networks. The intellectual merit of this project is in the innovative topology, design, control, development, packaging, and validation of the first charger which integrates an onboard charger and an auxiliary power module. This SBIR Phase I project involves the design of the converter, investigation and design of the controller, design and implementation of the electromagnetic interference filter stage, creating the schematics and layout, thermal management, reliability analyses, enclosure design, and final alpha prototype assembly and verification. This important work will (1) lead to theoretical advancements in the design, control, and integration of power electronic converters, (2) involve interdisciplinary research in power electronics, control, packaging, and thermal management, and (3) lead to commercialization of the first integrated onboard charger and auxiliary power module for electric vehicles.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该项目的更广泛的影响/商业潜力是为电动汽车开发第一个低成本和集成在板载充电器和辅助电源模块，从而促进了下一代电气运输系统的部署。值得注意的是，美国有超过40％的温室气体和70％的排放量来自运输部门，有超过2.5亿辆注册的乘用车，运输依赖于一种燃料来源99％。如果美国要获得能源安全并大大减少碳排放，则必须采用主流电动汽车。电动汽车行业已经通过了临界点。但是，电动汽车仍处于开发的早期阶段。像早期的计算机一样，构成电动汽车的碎片是大型，沉重，昂贵且无法在彼此之间有效沟通的。提出的技术不仅减少了电动汽车上机上充电器的数量，成本和重量，还可以提高其效率，并使双向操作能够支持未来的智能电网功能。该项目一旦技术成熟，该项目将在商业化方面创造就业机会。这项小型企业创新研究（SBIR）I阶段项目将导致电动汽车的创新综合和双向板载充电器的设计和开发。当前，所有即将到来的和市售的电动汽车都配备了个人在板载充电器，以充电牵引力电池和额外的辅助电源模块，以供电辅助负载。这些转换器沉重，笨重，昂贵，需要在各种控制器区域网络上进行沟通。该项目的智力优点在于创新的拓扑，设计，控制，开发，包装和验证的第一个充电器，该充电器集成了板载充电器和辅助功率模块。这个SBIR I期项目涉及电磁干扰过滤阶段的控制器，设计和实施的转换器，调查和设计的设计，创建原理图和布局，热管理，可靠性分析，外壳设计以及最终的Alpha Prototyper类型组件和最终的Alpha Prototyper组件和组件组件和组件。确认。这项重要工作（1）将导致电力电子转换器的设计，控制和集成的理论进步，（2）涉及电力电子，控制，包装和热管理方面的跨学科研究，以及（3）导致商业化该奖项反映了NSF的法定任务，这是第一个集成在板载充电器和辅助电源模块。该奖项被认为是值得通过基金会的知识分子优点和更广泛影响的审查标准来评估值得支持的。
