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个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，随着世界各地人口密集的城市中心的发展，这种情况可能会变得更糟。即使是有限形式的电气化，也将导致全球温室气体排放的实质性减少。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电子是一家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部件状态监测、测试和表征工具和策略项目的延续。到目前为止，这种合作已经导致了电池测试仪的开发和一种被称为工业扩展多尺度主成分分析（IEMSPCA）的算法，该算法先前已应用于汽车启动器和发电机。IEMSPCA已经商业化，现在是所有D&V测试单元的组成部分。电池测试器也已经商业化，具有世界上最先进的功能。它能够在汽车测试单元上进行驱动循环测试，阻抗表征和库仑效率测量。该提案建立并维持麦克马斯特和D&V电子公司之间现有的成功合作。它涉及两个主题的进一步研究和发展：1)基于信号的旋转部件故障检测与诊断；2)基于模型的电池表征与测试。研究成果将集成到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.
