The project establishes a new experimental facility at the University of Michigan – Dearborn. The main element of the facility, the accelerating rate calorimeter (ARC), will enable new opportunities to conduct research, education, and outreach in the area of management of thermal behavior of automotive batteries at the participating universities. The thermal behavior is a significant concern for the ongoing transition of the automotive technology to electric vehicles. The problems of degradation of battery’s performance at low and high temperatures, the danger of battery thermal runaway, overheating of fast chargers, etc. continue to be major challenges. The universities participating in the project are major feeders of engineering workforce and hubs of fundamental and applied research for the automotive industry in the Southeast Michigan, which includes the Big Three automakers and many of their suppliers. The new facility will stimulate growth of research in the area of vehicle electrification and battery technology. The facility will be incorporated in instruction of at least ten graduate and undergraduate courses, thus helping to build skills of future engineers, who will lead the nation’s transition to electric mobility. Expanded research opportunities for students will be created. The facility will also enable outreach activities to promote diversity, equity and inclusion in the Detroit area to inspire STEM interest in K-12 students.The proposed ARC system is an effective tool to quantify features of thermal behavior, such as temporospatial temperature, reaction onset temperature, heat capacity, heat release rate, pressure rise rate, and gas generated under regular and extreme conditions. It will create new knowledge in numerous interdisciplinary areas, including battery degradation and safety, battery material development and testing, battery health monitoring, chemical gas sensing, CO2 adsorption, power electronics, and grid applications. The ARC system will enable exploration of exothermic runaway reactions from hazardous and reactive chemicals at a laboratory scale by simulating abusive extreme conditions such as nail penetration, crushing, overcharging, external short circuit, etc. The sealed chambers of the ARC will guarantee safe operation. A major advantage of the ARC in comparison with typical isothermal calorimeters is its smaller response time. This will allow us to measure very small heat releases and, as an example, quantify runaway explosive decompositions for a wide range of materials and devices, such as batteries, power electronics, and chemical materials. Acquisition of the proposed ARC system will enable more than 20 faculty at the University of Michigan - Dearborn and neighboring universities, all located in the Southeast Michigan, to conduct new research activities. The proposed instrument will also support interdisciplinary research collaboration among the participating universities and between the universities and industries, such as Ford Motor, GM, and Stellantis.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.

该项目在密歇根大学迪尔伯恩建立了一个新的实验设施。该设施的主要组成部分，加速量热仪（ARC），将为参与大学在汽车电池热行为管理领域进行研究，教育和推广提供新的机会。热行为是汽车技术向电动汽车过渡的一个重要问题。电池在低温和高温下的性能退化、电池热失控的危险、快速充电器过热等问题仍然是主要挑战。参与该项目的大学是密歇根州东南部汽车行业工程劳动力的主要来源和基础和应用研究的中心，其中包括三大汽车制造商及其许多供应商。新设施将刺激汽车电气化和电池技术领域的研究增长。该设施将纳入至少十门研究生和本科生课程的教学中，从而帮助培养未来工程师的技能，他们将领导国家向电动汽车的转型。将为学生创造更多的研究机会。该设施还将使外展活动，以促进多样性，公平和包容性在底特律地区，以激发在K-12学生STEM的兴趣。拟议的ARC系统是一个有效的工具，以量化热行为的功能，如时空温度，反应起始温度，热容，热释放速率，压力上升速率，以及在常规和极端条件下产生的气体。它将在许多跨学科领域创造新知识，包括电池退化和安全，电池材料开发和测试，电池健康监测，化学气体传感，二氧化碳吸附，电力电子和电网应用。ARC系统将能够在实验室规模下通过模拟极端条件（如钉子穿透、破碎、过充、外部短路等）来探索危险和活性化学品的放热失控反应。ARC的密封腔室将确保安全运行。与典型的等温量热计相比，ARC的主要优点是响应时间更短。这将使我们能够测量非常小的热释放，并作为一个例子，量化失控的爆炸分解为广泛的材料和设备，如电池，电力电子和化学材料。收购拟议中的ARC系统将使密歇根大学迪尔伯恩和邻近大学的20多名教师能够开展新的研究活动，这些大学都位于密歇根州东南部。拟议的工具还将支持参与大学之间以及大学与福特汽车、通用汽车和Stellantis等行业之间的跨学科研究合作。该奖项反映了NSF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。
