The broader impact/commercial potential of this I-Corps project is the large-scale reuse of electric vehicle batteries in low-cost, stationary energy storage systems. Society is becoming increasingly dependent on batteries. Electric vehicles, which are powered exclusively by batteries, represent an increasing share of total vehicle sales. Similarly, large, stationary batteries are now commonly connected to electric grids to increase the affordability and reliability of electricity. Over 75% of an electric vehicle battery's original capacity typically remains at the end of its useful life in a vehicle, and recycling the batteries is expensive and inefficient. To defer the expense of recycling and reduce e-waste, electric vehicle batteries may instead be reused for years more. Reuse would also limit the nation's dependence on imported batteries and the precious metals required to manufacture them. Finally, reused batteries can meet a critical market need for affordable energy storage. Electric utilities and grid operators demand energy storage to reduce the cost of providing reliable electricity. This demand will grow as variable, renewable electricity generators (e.g. wind turbines and solar panels) continue to gain popularity. Similarly, consumers demand energy storage for backup power and to reduce their electricity bills.This I-Corps project will further develop a technology which enables the safe, efficient, low cost reuse of electric vehicle batteries. The technology reduces the time required to test used batteries, optimizes used battery reassembly, and improves used battery performance. The algorithms accurately measure the health of individual battery cells in minutes, rather than hours. Then, the algorithms optimize the reconfiguration of used battery cells, which increases the efficiency and longevity of used battery systems. Finally, the system equips the used batteries with advanced control systems, which account for variable battery characteristics to further extend lifetime and boost efficiency. These capabilities have enabled a commercial-scale demonstration system.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I-Corps项目的更广泛的影响/商业潜力是在低成本的固定储能系统中大规模重复使用电池。社会越来越依赖电池。电动汽车仅由电池提供动力，代表了车辆总销售额的份额。同样，大型固定电池现在通常连接到电网，以提高电力的负担能力和可靠性。电动汽车电池的原始容量中，超过75％的电池通常保留在车辆使用寿命的尽头，并且回收电池价格昂贵且效率低下。为了推迟回收利用和减少电子废物的费用，电池可能会多多年。再利用还将限制国家对进口电池的依赖以及制造它们所需的贵金属。最后，重复使用的电池可以满足负担得起的能源存储的关键市场需求。电力公司和电网运​​营商需要储能，以降低提供可靠的电力的成本。这种需求将随着可变的可再生电力发生器（例如风力涡轮机和太阳能电池板）的流行而增长。同样，消费者要求存储能源以备用电源并减少电费。这项I-Corps项目将进一步开发一项技术，以实现安全，高效，低成本的电动汽车电池。该技术减少了测试用过的电池所需的时间，优化了使用的电池重新组装并改善了使用的电池性能。该算法可以在几分钟而不是数小时内准确测量单个电池电池的健康状况。然后，算法优化了用过的电池电池的重新配置，从而提高了使用的电池系统的效率和寿命。最后，该系统将二手电池配备了高级控制系统，该系统占了可变的电池特性，以进一步延长寿命并提高效率。这些功能已经实现了商业规模的演示系统。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影响的评论标准来评估值得支持的。
