Condition monitoring and testing of powertrain elements

世界各国政府都在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全面的战略，其中包括清洁汽车技术。交通导致的温室气体(GHG)排放被认为是气候变化的主要贡献者之一，随着世界各地人口稠密的城市中心的增长，温室气体排放可能会变得更糟。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，汽车电气化应被视为应对气候变化综合战略的一个基本要素。我们的行业合作伙伴D&V电子是汽车电气化测试设备的供应商。这项提议是与D&V电子公司关于开发电动汽车动力总成部件的状态监测、测试和表征工具和战略的项目的继续。到目前为止，这种合作已经导致开发出一种电池单元测试仪和一种称为工业扩展多尺度主成分分析(IEMSPCA)的算法，该算法以前已应用于汽车起动器和发电机。IEMSPCA已经商业化，现在是所有D&V测试单元的组成部分。电池单元测试仪也已经商业化，具有世界上最先进的功能之一。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。这一提议建立并维持了麦克马斯特和D&V电子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；以及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.
