Condition monitoring of powertrain components in electrified vehicles

“中加清洁汽车运输联合倡议”为将加拿大麦克马斯特大学和北京理工大学正在进行的研究结合起来提供了一个及时的机会。推动这个项目的一些因素是：目前全球正在对电动汽车的开发和部署进行大量投资，中国是并且将继续是电动汽车的早期采用者。传统内燃机（ICE）技术在发动机控制系统中内置了广泛的状态监测功能。适合电动汽车的状态监测，使这项新技术能够与现有的ICE技术竞争，是一个活跃的研究领域，并且行业需求很高。对于这个提案，我们打算开发和完善由麦克马斯特和BIT开发的状态监测技术，并将其应用于由行业合作伙伴制造的商用设备中。对于所有电动汽车来说，电池仍然是最关键的部件之一。目前用于电池系统开发的电池监测系统以及用于优化车载电池管理系统的电池监测系统都需要可靠地测量电池的充电状态（SOC）和健康状态（SOH）。现有的SOH测量技术通常相当不精确，因此在电池系统优化中的应用有限。麦克马斯特大学在故障检测和预测方面做了大量的研究，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。D&V electronics总部位于安大略省Woodbridge，是一家测试设备供应商，在全球汽车电气元件测试设备中占有重要份额。Eontronix是一家总部位于中国的**分销商和系统集成供应商。上海eddrive是中国非常重要的电动汽车驱动电机系统制造商，拥有广泛的研究能力，并在中国电动汽车零部件市场占有很大份额。北京理工大学是中国领先的研究机构，拥有大型项目**，专门研究电动汽车。与D&V和McMaster的拟议合作将把McMaster开发的SOC和SOH算法与D&V设计和制造的设备相结合，以提供具有精确SOC和SOH功能的商业**产品。同样，BIT将把其研究应用于电动马达和传动系统的状态监测，Eontronix将把这些技术应用于测试实验室和车载组件。最终的结果将是用于混合动力汽车电池、电动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
