Direct-drive e-Powertrain with Integrated Charging Capability

电动车辆（EV）的设计在上个世纪已经改变。电动汽车很受欢迎，但没有任何设计能够激发公众的想象力。消费者知道电动汽车在节约成本和保护环境方面具有良好的经济意义。然而，电动汽车在市场上的占有率很低。需要技术和营销的成功结合，使电动汽车对公众来说是可取的和不可或缺的。为了为电动汽车提供新的技术解决方案，以开发负担得起的实用电动汽车，该提案延续了Kar博士在电动汽车，机器，驱动和充电技术方面的重点突出，现实，可行，创新和变革的研究活动。传统的电动汽车具有固定的传动比，将电动机连接到差速器和车轮。用直驱动力系统取代现有变速器将大大减少机械损失（根据工况的不同，减少2%-20%）。它还将提高车辆的整体运行效率。开发高性能电机沿着发展，特别是满足直接驱动要求。此外，当车辆不运动时，EV内现有的机器/电力电子转换器可以重新配置为1相（1级）或3相（3级）充电器。这种电机驱动/电池充电器集成将允许充电站仅通过三相或单相电源插座为电动汽车提供电力。这将大大节省基础设施建设的成本。本提案的目标：通过解决与研究相关的问题，具有广度和范围-直接驱动电机及其驱动器（具有/不具有集成充电能力）的设计。该研究还将有助于“加拿大制造”下一代电动汽车的设计/开发。知识的进步，影响该领域的思想/活动方向也是关键。该研究的愿景/影响包括从成本和环境效益的角度为公众设计理想的电动汽车，并刺激该领域的更大创新。这将使电动汽车既受欢迎又不可或缺，从而增加其受欢迎程度。这些好处将在短期和长期内提高电动汽车在市场上的销售和存在。这种普及将促进加拿大的国内生产总值（GDP），并确保加拿大的电动汽车行业在短期和长期内具有全球竞争力。

The designs of electric vehicles (EVs) have changed over the last century. EVs are popular, but no design has captured the public's imagination. Consumers know that EVs make good economic sense in terms of cost savings and benefit to the environment. Yet, EVs' presence in the marketplace is low. A winning combination of technology and marketing is needed to make EVs desirable and indispensable to the public. To provide novel technological solutions for EVs for the development of affordable, practical EVs, this proposal continues Dr. Kar's well-focused, realistic, feasible, innovative and transformative research activities in EVs, machines, drives and charging technologies. Conventional EVs have a fixed gear ratio transmission connecting the electric motor to the differential and wheels. Replacing the existing transmission with direct-drive powertrain will greatly reduce the mechanical losses (2%-20% depending on operating conditions). It will also improve overall vehicle operating efficiency. It is essential to develop high performing electric machines along with drives, especially, to meet the direct-drive requirements. Also, the existing machine/power electronic converters within the EV can be reconfigured into a 1-phase (level 1) or 3-phase (level 3) charger when the vehicle is not in motion. This motor drive/battery charger integration will allow charging stations to provide electric power to EVs only with 3-phase or 1-phase power outlets. This will greatly save costs on infrastructure development. This proposal's objective: Has breadth and scope by addressing issues associated with research-the design of direct-drive electric machines and their drives with/without integrated charging capability. The research will also help the design/development of "Made in Canada" next-generation EVs. The advancement of knowledge, influencing the direction of thought/activity in the field are also key. The research's vision/impact includes designing EVs that are desirable from both a cost and environmental benefit perspective for the public and spur greater innovation in the field. This will make EVs both desirable and indispensable-increasing their popularity. These benefits will enhance the sales and presence of EVs in the marketplace both in the short- and long-term. This popularity will boost Canada's gross domestic product (GDP) and ensure Canada's EV industry is globally competitive in both the short- and long-term.**
