Condition monitoring and testing of powertrain elements

世界各国政府都承认气候变化及其潜在的灾难性后果。应对气候变化需要一项包括清洁汽车技术在内的综合战略。交通运输造成的温室气体（GHG）排放被认为是气候变化的主要原因之一，并且随着世界各地人口稠密的城市中心的增长，这种排放可能会变得更加严重。即使是有限形式的电气化，也将导致全球温室气体排放量的大幅减少。因此，车辆电气化应被视为应对气候变化综合战略的重要组成部分。我们的行业合作伙伴 D&V Electronics 是汽车电气化测试设备的供应商。该提案是与 D&V Electronics 合作开发电动汽车动力总成组件状态监测、测试和表征工具及策略项目的延续。迄今为止，这种合作已开发出电池测试仪和称为工业扩展多尺度原理元件分析（IEMSPCA）的算法，该算法此前已应用于汽车起动机和发电机。 IEMSPCA 已商业化，现已成为所有 D&V 测试单元的组成部分。电池测试仪也已商业化，其功能处于世界最先进水平。它能够在汽车测试单元上以集成形式执行驱动循环测试、阻抗表征和库仑效率测量。该提案建立并维持了 McMaster 与 D&V Electronics 之间现有的成功合作。它涉及两个主题的进一步研究和开发：1）基于信号的旋转部件故障检测和诊断； 2) 基于模型的电池表征和测试。研究成果将整合到D&V平台上。

Governments throughout the world are acknowledging climate change and its potentially catastrophic consequences. Combating climate change requires a comprehensive strategy that includes clean automotive technologies. Green House Gas (GHG) emissions due to transportation are considered one of the main contributors to climate change and are likely to become worse with the growth of densely populated urban centers around the world. Even limited forms of electrification, will lead to substantive reductions in global GHG emissions. As such, vehicle electrification, should be considered an essential element of an integrated strategy for combating climate change. Our industry partner, D&V Electronics, is a supplier of test equipment for vehicle electrification. This proposal is a continuation of a project with D&V Electronics on developing condition monitoring, testing and characterization tools and strategies for electric vehicle powertrain components. This cooperation has so far resulted in the development of a battery cell tester and an algorithm referred to as the Industrial Extended Multi-Scale Principle Components Analysis (IEMSPCA) that has previously been applied to automotive starters and generators. The IEMSPCA has been commercialized and is now an integral element of all D&V test cells. The battery cell tester has also been commercialized and has functionalities that place amongst the most advanced in the world. It is capable of performing drive cycle testing, impedance characterization, and coulombic efficiency measurements in an integrated form on automotive test cells. This proposal builds and sustains the existing successful collaboration between McMaster and D&V Electronics. It involves further research and development along two themes: 1) Signal-based Fault Detection and Diagnosis for rotating components; and 2) Model-based battery characterization and testing. The research outcomes will be integrated onto D&V platforms.
