Condition monitoring of powertrain components in electrified vehicles

加拿大中国关于清洁汽车交通的联合倡议提供了一个及时的机会，将加拿大麦克马斯特大学和北京理工大学(BIT)目前正在进行的研究**结合在一起。推动该项目的一些**因素是：目前全球正在**进行电动汽车开发和部署的大笔投资，中国是并将继续是电动汽车的先行者。传统的内燃机(ICE)技术在发动机控制中内置了广泛的状态监控。对电动汽车进行适当的状况监测，使这项新技术能够与现有的内燃机技术竞争，这是一个**积极研究和行业需求很高的领域。对于这项提议，我们打算开发和改进由麦克马斯特和BIT开发的状态监测**技术，并在**行业合作伙伴制造的商业设备中实施这些技术。对于所有电动汽车来说，电池仍然是最关键的部件之一。用于开发电池系统的当前电池**监控系统以及用于车载**电池优化的监控系统：纳米管理系统需要可靠地测量电池的荷电状态(SOC)和健康状态**(SOH)。现有的SOH测量技术通常非常不精确，因此在电池系统的**优化中使用有限。麦克马斯特大学在故障检测和预测方面做了大量研究，我们的研究在应用这些技术来确定电池系统的SOC和SOH**方面显示出巨大的前景。总部位于安大略省伍德布里奇的D&V Electronics是一家测试设备供应商，在汽车电子部件测试设备领域占有相当大的**份额。Eontronix是一家总部位于中国的公司，既是**分销商，也是系统集成供应商。上海EDRIVE是中国非常重要的电动汽车驱动电机**制造商，拥有广泛的研究能力，并提供中国电动汽车**零部件市场的很大份额。北京理工大学(BIT)是中国领先的研究机构，拥有一个专门研究电动汽车的大型项目。与D&V和麦克马斯特拟议的合作·将把麦克马斯特开发的SOC和SOH**算法与D&V设计和制造的设备结合起来，提供具有精确SOC和SOH能力的商业**产品。同样，BIT将把其研究应用于电机和传动系统的状态监测，而Eontronix将把这些技术应用于测试实验室和车载**组件。最终成果将是混合动力汽车电池、电机和变速器的状态监测系统

The joint Canada China initiative on Clean Automotive Transportation offers a timely opportunity to combine current**research being conducted at McMaster University in Canada and Beijing Institute of Technology (BIT). Some of the**factors motivating this project are: a large investment in the development and deployment of electrified vehicles is**currently underway globally, China is, and continues to be, an early adopter of electrified vehicles. Conventional internal**combustion engine (ICE) technology has extensive condition monitoring built into the engine controls. Suitable condition**monitoring for electrified vehicles to allow this new technology to compete with the existing ICE technology is an area of**active research and in high demand by industry. For this proposal we intend to develop and refine condition monitoring**techniques developed by McMaster and BIT and implement them in commercial equipment manufactured by the**industry partners. For all electrified vehicles the battery remains one of the most critical components. Current battery**monitoring systems used for the development of the battery systems as well as those used for the optimization of invehicle**battery r:nanagement systems requires reliable measurement of the state of charge (SOC) and state of health**(SOH) of the battery. Existing techniques for SOH measurements are generally quite imprecise and thus of limited use in**optimization of the battery system. McMaster University has done considerable research on fault detection and**prognostics, and our research is showing great promise in applying these techniques to determine both SOC and SOH**of battery systems. D&V electronics, based in Woodbridge Ontario, is a supplier of test equipment with a significant**global share of vehicle electrical component test equipment. Eontronix is a company based in China that is both a**distributor and a systems integration supplier. Shanghai Edrive is a very important manufacturer of EV driving motor**systems in China with extensive research capabilities and supplies a large share of the Chinese market for EV**components. Beijing Institute of Technology (BIT) is a leading Chinese research institute with a large program**specializing in electrified vehicles. The proposed collaboration· with D&V and McMaster will combine the SOC and SOH**algorithms developed at McMaster with the equipment designed and manufactured by D&V, to provide a commercial**product with accurate SOC and SOH capabilities. Similarly, BIT will apply its research to condition monitoring of electric**motor and transmission systems and Eontronix will apply these techniques to both the test lab and in-vehicle**components. The final result will be condition monitoring systems for batteries, electric motors and transmissions of HEV
