目的：该项目的目的是为电动汽车开发一种新型混合能源存储系统。具体目标是：(a)将储能系统（由高能量密度电池组、超级电容器组和DC/DC转换器组成）的重量降低到低于单独的高功率密度电池组的重量，同时延长电池寿命；(b)在一款新型电动汽车的动力系统上实施、开发和验证这项技术。智能优势：智能优势体现在先进储能技术的设计、优化、电源管理、热管理和验证方面。提出的研究背后的潜在基础是提供一种变革性的解决方案，以克服电池的电流限制，通过(a)基于SiC的新型转换器和(b)独特的解耦功率/能量管理策略来优化控制系统。该项目整合了电气工程、机械工程和应用数学等不同学科，从而促进了多学科的合作研究。更广泛的影响：更广泛的影响包括最高质量的综合教育和研究，通过培养有才能的学生来满足美国能源和运输行业新兴的劳动力和教育需求。该团队的目的是通过与马里兰州LSAMP项目的密切合作，扩大女性和少数民族学生对该项目的参与。此外，该团队将与巴尔的摩-华盛顿电动汽车倡议合作，在可持续交通系统的战略领域对大西洋中部地区的高中生和大学生进行广泛的教育。

Objective: The objective of this program is to develop a novel hybrid energy storage system for electric vehicles. The specific objectives are to: (a) reduce the weight of the energy storage system (composed of high energy-density battery pack, ultracapacitor pack and a DC/DC converter) to less than the weight of a high power-density battery pack alone, while increasing the battery lifetime; (b) implement, develop, and validate this technology on the powertrain of a new electric car.Intellectual Merit: The intellectual merit is in the design, optimization, power management, thermal management, and validation of the advanced energy storage technology. The underlying foundation behind the proposed research is to provide a transformative solution to overcome current limitations of the batteries, achieved by (a) a SiC based novel converter and (b) a unique decoupled power/energy management strategy to optimally control the system. The project integrates different disciplines such as electrical engineering, mechanical engineering, and applied mathematics, thus fostering multidisciplinary collaborative research. Broader Impacts: The broader impacts include the highest quality integrated education and research to meet the emerging workforce and educational needs of U.S. energy and transportation industry by educating talented students. It is the intention of the team to broaden the participation of female and minority students in this project through close collaboration with the Maryland LSAMP program. In addition, the team will collaborate with the Baltimore-Washington Electric Vehicle Initiative to educate a broad range of high school and college students in mid-Atlantic region in strategic field of sustainable transportation systems.
