There are few more pressing challenges of our time than the stewardship of our planet's air. Rising atmospheric carbon dioxide levels are a major contributor to global warming and air pollution kills an estimated 4,000 people a day in China. In Canada and the U.S., the transportation sector creates roughly 25% of the greenhouse gases emitted. We must transition to electric vehicles (EVs) powered by sustainable electricity generation in order to combat these global problems. However, globally, EV sales account for less than 1% of new sales. The main obstacles to widespread EV adoption are high initial costs, range concerns, and charging infrastructure. My proposed research program will use a holistic approach to advance the science of EVs by integrating 3 levels of research: (1) power electronic circuit design, (2) vehicle-level design, modeling, and control, and (3) grid-level integration of EVs. While these areas are often considered separately, my program will consider the interactions between them in order to make discoveries that will lead to reduced vehicle cost and increased vehicle efficiency, reliability, and range. My short-term objectives are:1) Power Electronic Level Advance power electronic converter design using wide-band-gap devices. The anticipated outcome is converter designs with increased efficiency and decreased volume and cost.2) Vehicle Level Develop new multi-scale modeling techniques. The anticipated outcome is a tool for efficient EV powertrain design which we will use to study interactions between the powertrain electronics, vehicle system-level performance, and EV grid integration. 3) Vehicle Level Optimize autonomous vehicle control strategies for powertrain efficiency. The anticipated outcome is algorithms that specify the precise speed the vehicle should travel at for each instant in a trip to maximize powertrain efficiency in the face of constantly-changing external factors. 4) Grid Level Develop strategies to optimize the integration of large numbers of EVs with the grid. The anticipated outcome is algorithms and methods that take a vehicle-centered approach to smart-charging by first considering the driver's need for battery charge.The primary impact of this program is to improve the environment and the health of people living in urban centers, in Canada and worldwide. There is a further benefit to Canada in establishing itself as a leader in the advanced vehicle space, which is a fast-growing opportunity for high-tech well-paying jobs for Canadians. My proposed research program will train HQP in the highly-sought after areas of power electronics, vehicle modeling, design, and control, and smart grid. Due to the integrated nature of my program, my graduates will be leaders who can make technical advances while also understanding the bigger picture. Our advancements will help shape the future evolution of electrified and autonomous vehicles.

在我们这个时代，很少有比管理我们星球的空气更紧迫的挑战了。大气中二氧化碳含量的上升是全球变暖的主要原因，在中国，空气污染估计每天造成4,000人死亡。在加拿大和美国，运输部门产生了大约25%的温室气体排放。我们必须过渡到由可持续发电提供动力的电动汽车（EV），以应对这些全球问题。然而，在全球范围内，电动汽车销量占新销量的比例不到1%。广泛采用电动汽车的主要障碍是初始成本高，范围问题和充电基础设施。我提出的研究计划将采用整体方法，通过整合3个层次的研究来推进电动汽车科学：（1）电力电子电路设计，（2）车辆级设计，建模和控制，以及（3）电动汽车的电网级集成。虽然这些领域通常被单独考虑，但我的计划将考虑它们之间的相互作用，以便发现将导致降低车辆成本和提高车辆效率，可靠性和范围的发现。我的近期目标是：1）电力电子水平先进的电力电子变换器设计使用宽带隙器件。预期的结果是转换器设计具有更高的效率和更小的体积和成本。2）车辆级开发新的多尺度建模技术。预期的结果是一个有效的电动汽车动力系统设计的工具，我们将使用它来研究动力系统电子设备，车辆系统级性能和电动汽车电网集成之间的相互作用。3)车辆级别优化自动驾驶车辆控制策略，提高动力系统效率。预期的结果是算法，指定精确的速度，车辆应该行驶在每一个瞬间的行程，以最大限度地提高动力系统的效率，面对不断变化的外部因素。4)制定策略以优化大量电动汽车与电网的整合。预计的成果是算法和方法，采取以车辆为中心的方法，首先考虑驾驶员对电池充电的需求。该计划的主要影响是改善加拿大和世界各地城市中心居民的环境和健康。加拿大在先进汽车领域成为领导者还有一个好处，这是加拿大人获得高科技高薪工作的快速增长机会。我提出的研究计划将在电力电子，车辆建模，设计和控制以及智能电网等备受追捧的领域培训HQP。由于我的计划的综合性，我的毕业生将成为领导者谁可以使技术进步，同时也了解更大的图片。我们的进步将有助于塑造电动和自动驾驶汽车的未来发展。
