GOALI: PDE Techniques for Battery Management Systems

智力价值该项目将开发锂离子电池的状态估计器、参数估计器和控制器。电池单体中的电化学动力学(电解液和电极中固体颗粒中锂的电流、电位和浓度的分布)和电池组中的热动力学(由电池中的电过程引起的温度漂移，并导致潜在的致命的热失控？)会被钉上钉子。这两个系统都用耦合的非线性偏微分方程组来建模。为这些数学上复杂的系统开发的估计和控制设计将是该项目的主要智力成果。作为GALI项目的工业合作伙伴，博世将贡献其在电池物理、建模和最先进的电池管理系统方面的丰富专业知识。博世还将提供用于测试结果的实验设施。更广泛的影响更广泛的影响将包括派？S继续努力指导未被充分代表的学生，包括女性、西班牙裔和非裔美国人，以及向加州大学洛杉矶分校的S普赖斯学校伸出援手，这所学校是全国十大高中之一，该学校主要招收市中心的拉美裔孩子。博世的PI和Co-PI将向高中生介绍储能和汽车控制技术的基础知识。国际和平研究所将组织一次关于能量储存系统控制的研讨会。

Intellectual MeritThe project will develop state estimators, parameter estimators, and controllers for Lithium-ion batteries. Both the electrochemical dynamics in individual battery cells (the distribution of currents, potentials, and concentrations of lithium in electrolyte and in the solid particles in the electrodes) and thermal dynamics in battery packs (the excursions of temperature caused by the electric processes in cells and leading to the potentially fatal ?thermal runaway?) will be tacked. Each of the two systems is modeled by coupled systems of nonlinear PDEs. Estimation and control designs that will be developed for these mathematically complex systems will be the main intellectual outcome of the project. As the industrial partner in this GOALI program, Bosch will contribute its vast expertise in battery physics, modeling, and in the state-of-the-art in battery management systems. Bosch will also provide its experimental facilities for the testing of results. Broader ImpactThe broader impacts will include the PI?s continued effort in mentoring underrepresented students, including women, Hispanics, and African-Americans, and an outreach to UCSD?s Preuss School, one of the nation's top ten high schools, which enrolls mostly inner-city kids of Hispanic background. The high-school students will be introduced by the PI and by the Co-PI from Bosch to the basics of energy storage and automotive control technologies. The PI will work on organizing a workshop on control of energy storage systems.
