The broader impact/commercial potential of this Partnerships for Innovation – Research Partnership (PFI-RP) project is to enable the automotive industry to make battery-powered electric vehicles (BEVs) more affordable and with a longer driving range. This project will support the transition from fossil fuels to clean electric energy. Reduced costs and improved performance in terms of higher efficiency and longer driving range will accelerate the adoption of the BEV technology. The project will also create a unique partnership with an automotive industry leader that will train the next generation technical and entrepreneurship leaders to lead the US automotive industry. The outreach efforts through student competitions and the Engineer Your World high school engineering program will broaden the participation of a diverse student population. The proposed project is based on a disruptive battery-inverter architecture. Today’s battery in a BEV is a high voltage system based on series connection of many low voltage battery cells. In such architecture, all cells must perform together as a whole and any non-performing cell degrades the whole system’s performance and increases the cost due to the need for complicated management and mitigation components. The proposed project addresses this issue by allowing battery cells to operate almost independently based on their state of the health and state of charge. This architecture can substantially extend the overall battery life, effectively reducing the system cost. The novel inverter can also achieve much higher power conversion and motor efficiency, further extending the drive range of the BEVs. The project will develop a prototype system that will be tested to verify the thermal and electrical performance of the battery-inverter system and its suitability to be implemented in future BEV platforms.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.

这种创新合作伙伴关系的更广泛的影响/商业潜力 - 研究合作伙伴关系（PFI-RP）项目是使汽车行业能够使电池供电的电动汽车（BEVS）更加负担得起，并且行驶范围更长。该项目将支持从化石燃料到清洁电能的过渡。降低成本和提高效率和较长练习范围的性能将加速使用BEV技术。该项目还将与汽车行业领导者建立独特的合作伙伴关系，该公司将培训下一代技术和企业家精神领导者领导美国汽车行业。通过学生竞赛和工程师您的世界高中工程计划的宣传工作将扩大潜水员学生群体的参与。拟议的项目基于破坏性的电池逆变器架构。如今，BEV中的电池是基于许多低压电池电池的串联连接的高压系统。在这样的体系结构中，所有单元格必须整体和任何不表现的单元格都会降低整个系统的性能，并增加了由于需要复杂的管理和缓解组件而增加的成本。拟议的项目通过允许电池电池根据其健康状况和充电状态独立运行来解决此问题。该体系结构可以大大延长整体电池寿命，从而有效地降低了系统成本。新型逆变器还可以实现更高的功率转换和电动机效率，从而进一步扩展了BEV的驱动范围。该项目将开发一种原型系统，该系统将进行测试，以验证电池逆变器系统的热和电气性能及其在将来的BEV平台中实现的适用性。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子优点和更广泛的影响审查标准来通过评估来获得支持的。
