Development of Electric Medium-Duty Trucks (e-MDTs) through Model-Based Design and Optimization

对空气污染、温室气体(GHG)排放和以石油为基础的燃料价格波动的日益担忧导致了电池电动汽车(BEV)的发展。然而，BEV的进一步发展和更广泛的应用需要提高性能、运营里程、降低生命周期成本，以及针对特定利基市场的独特运营模式的新设计。中型卡车(MDT)提供了一种广受欢迎的低成本运输解决方案，主要用于城市道路上为工作人员运送工具、物资和材料。MDT行业现在才刚刚兴起，在更严格的温室气体和燃料效率法规下，在Bev开发方面取得了显着进展。该项目将解决当前BEV开发中的关键问题，并将重点放在开发新的电池供电电动MDT(e-MDT)的几项关键使能技术和设计工具上。我们的清洁交通研究团队在电动汽车(EV)研究方面拥有丰富的经验，将与我们的工业合作伙伴加拿大电动汽车有限公司(Canada Electric Vehicles Ltd.)合作开展这项工作，加拿大电动汽车有限公司专门从事小型电动汽车的生产。协作团队将介绍、测试和改进优化e-MDTS动力总成系统、关键动力总成部件选择/尺寸、动力控制/能源管理和底盘/悬挂系统在实际运行条件下的方法和流程。这项研究将介绍基于模型的设计和优化(MBDO)方法和流程，用于平衡性能和生命周期成本的e-MDTS。将制造并测试一辆概念验证车辆，以验证新的设计和控制优化工具和结果。这项合作旨在开发先进的e-MDT优化和控制方法，并在上市车辆上进行验证，并为加拿大未来的清洁汽车专家和领导者提供一流的培训。该计划将确保我们的电气化推进技术研究/培训计划以及加拿大电动汽车公司先进的Bev技术和产品的开发继续取得成功，并使加拿大汽车业受益。

Increasing concerns over air pollution, greenhouse gas (GHG) emissions, and volatile petroleum-based fuel prices have led to the development of Battery Electric Vehicles (BEVs). However, the further development and broader applications of BEVs need improved performance, operation range, lower lifecycle costs, and new designs for specific niche markets with unique operation profiles. The medium-duty trucks (MDTs) provide a popular low-cost transport solution used primarily on city roads for carrying tools, supplies, and materials for working crews. The MDT industry is only now emerging with notable progress in BEV development under the more stringent GHG and fuel efficiency regulations. This project will address the critical issues in current BEV development and focus on several critical enabling technologies and design tools to develop new battery-powered electric MDT (e-MDT). Our Clean Transportation Research Team, with extensive experience in electrified vehicle (EV) research, will carry out this work in collaboration with our industrial partner, Canadian Electric Vehicles Ltd., specializing in smaller EV production. The collaboration team will introduce, test and improve the methods and processes for optimizing the e-MDTs' powertrain system, critical powertrain component selection/sizing, power control/energy management, and chassis/suspension systems under real-world operating conditions. The research will introduce model-based design and optimization (MBDO) methods and processes for e-MDTs with balanced performance and lifecycle costs. A proof-of-concept vehicle will be built and tested to verify the new design and control optimization tools and results. The joint effort aims to develop advanced e-MDT optimization and control methods validated on market-ready vehicles and provide first-class training to Canada's future clean vehicle specialists and leaders. The program will ensure the continued success of our electrified propulsion technology research/training program and the development of advanced BEV technologies and products at Canadian Electric Vehicles and benefit the Canadian automotive industry.
