High efficiency electric vehicle drivetrains with integrated fast-charging and dual storage media

电动汽车已被证明在技术上是可行的，并即将大幅扩张。然而，电动汽车的大规模采用受到价格高、续航里程有限以及与使用传统充电器相关的极长充电时间的限制。该项目的目标是通过以下方式解决这些限制：(I)通过引入更适合城市驾驶的双储能介质来提高驾驶循环效率；(Ii)重新考虑标准动力传动系统以提高性能；(Iii)开发集成在车辆动力系统本身中的快速充电功能，极大地降低与快速充电相关的基础设施成本；以及(Iv)开发可为车队车辆应用提供中等充电率的无线充电技术。这些研究重点对电动汽车的成本和对昂贵的快速充电和车队充电基础设施的需求具有重大影响。与合作公司人员的接触将使学员了解工程研究和开发的实际方面，包括考虑机械约束、包装和汽车标准。

Electric vehicles have been shown to be technologically viable and are on the verge of significant expansion.However, mass adoption is limited by their high price, limited range and the exceptionally long charging timesassociated with the use of conventional chargers. The goal of this project is to address these limitations by (i)improving drive-cycle efficiencies by introducing dual energy storage media better suited to urban driving (ii)reconsidering the standard drivetrain system to improve performance, (iii) development of fast-chargingfunctionality that is integrated within the vehicle drivetrain system itself, vastly reducing infrastructure costsassociated with fast-charging and (iv) development of wireless charging technology that offer medium chargingrates for fleet vehicle applications. These research foci have major implications on EV cost and demands oncostly fast-charging and fleet charging infrastructure. Engagement with the partner company personnel willexpose trainees to practical aspects of engineering research and development including consideration ofmechanical constraints, packaging and automotive standards.
