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

对空气污染、温室气体（GHG）排放和石油燃料价格波动的日益关注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改进性能，操作范围，更低的生命周期成本，以及针对具有独特操作配置的特定利基市场的新设计。中型卡车（MDT）提供了一种流行的低成本运输解决方案，主要用于城市道路，为工作人员运送工具，用品和材料。MDT行业现在才刚刚出现，在更严格的温室气体和燃料效率法规下，BEV开发取得了显着进展。该项目将解决当前BEV开发中的关键问题，并专注于开发新型电池供电电动MDT（e-MDT）的几项关键使能技术和设计工具。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合作开展这项工作，专注于小型电动汽车的生产。合作团队将介绍、测试和改进用于优化e-MDT动力系统、关键动力系统部件选择/尺寸、动力控制/能源管理以及在实际操作条件下的底盘/悬架系统的方法和流程。该研究将介绍基于模型的设计和优化（MBDO）的方法和过程的e-MDT与平衡的性能和生命周期成本。将建造和测试概念验证车辆，以验证新的设计和控制优化工具和结果。双方的共同努力旨在开发先进的e-MDT优化和控制方法，并在市场上进行验证，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/培训计划的持续成功，以及加拿大电动汽车先进BEV技术和产品的开发，并使加拿大汽车行业受益。

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.
