Condition monitoring and testing of powertrain elements

世界各国政府正在认识到气候变化及其潜在的灾难性后果。应对气候变化需要包括清洁汽车技术在内的全面战略。交通运输导致的绿色温室气体（GHG）排放被认为是气候变化的主要因素之一，并且随着世界各地人口密集的城市中心的增长，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，车辆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 Electronics是汽车电气化测试设备的供应商。该提案是与D&V Electronics合作的一个项目的延续，该项目旨在为电动汽车动力总成组件开发状态监测、测试和表征工具和策略。到目前为止，这种合作已经开发出电池测试仪和一种被称为工业扩展多尺度主成分分析（IEMSPCA）的算法，该算法以前曾应用于汽车起动机和发电机。IEMSPCA已经商业化，现在是所有D&V测试单元的组成部分。电池测试仪也已商业化，并具有世界上最先进的功能。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和D&V Electronics之间现有的成功合作。它涉及进一步的研究和开发沿着两个主题：1）基于信号的故障检测和诊断旋转部件;和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.
