The broader impact/commercial potential of this Small Business Innovative Research (SBIR) Phase I project has potential to bring about global reductions in air-pollution and greenhouse gas emissions as the technology encourages the use of electric vehicles. There are over 272 million passenger cars registered in the United States and over one billion worldwide. As the transition to electric vehicles takes hold, potential markets for ultra-fast battery chargers for these electric vehicles will be sizeable. Estimates for the commercial market for electric vehicle charging stations is projected to reach $27.7 billion by 2027 from an estimated $2.5 billion in 2019. This project addresses the persistent problem of long electric vehicle recharging times and associated “range anxiety” among consumers. More specifically, an ultra-fast electric vehicle recharging system will be applied to emerging fast-charge batteries so that delays in re-energizing electric vehicles will be no more time-consuming than similar delays for refueling gasoline-powered vehicles. This SBIR Phase I project proposes to demonstrate the basic feasibility of an ultra-fast battery-charging system for consumer applications that can fully re-energize a typical light-duty electric vehicle in as little as six minutes. The project will focus on development of safe power conversion and transmission equipment that will be applied to power-matched fast-charge batteries currently emerging in commercial markets. Because the power levels required for ultra-fast EV charging are necessarily high, the project will focus on innovative measures to ensure public safety and system reliability while obtaining high electrical efficiencies. A relatively low power model will be constructed in Phase I for later scale-up. Solving technical challenges associated with an ultra-fast high-power electric vehicle charger has potential to advance knowledge of electromagnetics, power electronics, automated control, and materials science associated with ultra-fast electric vehicle recharging. The project will lead to new findings that will help solve the persistent problem of long delays in recharging electric vehicle batteries.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.

这项小型企业创新研究（SBIR）第一阶段项目的广泛影响/商业潜力有可能带来全球空气污染和温室气体排放的减少，因为这项技术鼓励使用电动汽车。在美国注册的乘用车超过2.72亿辆，全球超过10亿辆。随着向电动汽车的过渡，这些电动汽车的超高速电池充电器的潜在市场将是相当大的。预计到2027年，电动汽车充电站的商业市场规模将从2019年的25亿美元增至277亿美元。该项目解决了电动汽车充电时间过长和消费者“里程焦虑”的问题。更具体地说，一种超快速的电动汽车充电系统将应用于新兴的快充电池，这样，电动汽车重新充电的延迟将不会比汽油动力汽车加油的类似延迟更耗时。SBIR第一阶段项目旨在展示一种用于消费者应用的超快速电池充电系统的基本可行性，该系统可以在短短6分钟内为一辆典型的轻型电动汽车完全充电。该项目将重点开发安全的功率转换和传输设备，这些设备将应用于目前商业市场上出现的功率匹配快速充电电池。由于超快速电动汽车充电所需的功率水平必然很高，因此该项目将侧重于创新措施，以确保公共安全和系统可靠性，同时获得高电力效率。第一阶段将建造一个功率相对较低的模型，以备后期扩大规模。解决与超高速大功率电动汽车充电器相关的技术挑战，有可能推进与超高速电动汽车充电相关的电磁学、电力电子、自动化控制和材料科学的知识。该项目将带来新的发现，有助于解决电动汽车电池充电长时间延迟的长期问题。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
