Electric Powertrain Component Testing

*本提案涉及为电气化动力总成的关键部件(包括电池组、电机及其控制系统)开发高功率高频仿真(HPHFE)测试系统。HPHFE将是此类系统中的第一个，因为它可以灵活地以高带宽和高功率的同步形式整形和模拟信号。*运输业正在经历一场颠覆性的变革。内燃机正在被电力推进系统取代或补充。动力总成正在迅速发展，迫切需要基础设施来支持电动总成部件的研究和开发，即电动马达、电池组及其控制系统。准确和完整地评估电动马达和电池对汽车行业至关重要，使它们能够验证和改进计算机模型，执行竞争性基准测试，了解这些子系统将如何与车辆中的其他子系统交互(车辆集成)，并评估它们在现实世界条件下的性能，包括故障。*麦克马斯特机电和混合动力技术中心(CMHT)为电气化研究组装了最先进的设备，包括电池测试和电机测功机测试，以及相关的控制仪器。拟议的高功率高频仿真(HPHFE)测试系统将能够模拟3个同步的高功率信号，在其电流和电压幅度方面具有完全的灵活性，并具有高带宽。HPHFE增强和完善了CMHT的能力，并具有独特的功能，这是任何其他设备所不具备的。有了这个仿真器，CMHT中心将能够提供一个全面的环境，用于测试大多数电动乘用车(从轻型混合动力车到全电动汽车)常见功率和扭矩范围内的任何电动马达或电池组。它将允许进行开发和测试，而不受其控制系统的限制，以及通常与控制器硬件(速度、波形、电气开关、噪声)相关的限制。由于仿真器将完全控制提供给被测电机或电池的电压和电流，它将在高功率/高频运行范围内提供先进的测试功能和功率分析，而不需要额外的高保真仪器。HPHFE系统开发和测试电气化动力总成部件的新能力对具有重要战略意义的汽车行业具有变革性。**

******This proposal involves the development of a High Power High Frequency Emulation (HPHFE) test system for key components of electrified powertrains including battery packs, electric motors, and their control systems. The HPHFE would be the first of its kind because of its flexibility to shape and emulate signals in a synchronized form with high bandwidth and high power.******The transportation sector is going through a disruptive change. Internal combustion engines are being replaced or complemented by electric propulsion systems. Powertrains are evolving rapidly and there is a pressing need for infrastructure that would support research and development of electric powertrain components, namely electric motors, battery packs, and their control systems. Accurate and complete evaluation of electric motors and batteries is essential for the automotive industry and enables them to validate and improve computer models, perform competitive benchmarking, understand how these subsystems will interact with others in the vehicle (vehicle integration), and evaluate their performance under real world conditions, including faults. ******McMaster's Centre for Mechatronics and Hybrid Technologies (CMHT) has assembled state-of-the-art equipment for electrification research that include battery cell testing as well as electric motor dynamometer testing, and associated control instrumentation. The proposed High Power High Frequency Emulation (HPHFE) test system will be able to emulate 3 synchronized high-power signals with complete flexibility in terms of their current and voltage amplitudes with a high bandwidth. The HPHFE augments and completes CMHT's capabilities and has a functionality that is unique and does not exist in any other equipment. With this emulator, the CMHT centre will be able to provide a comprehensive environment for testing of any electric motor or battery pack within the common power and torque band of most electric passenger cars (from mild hybrids to full electric vehicles). It will allow development and testing to be conducted without the constraints of their control systems and the restrictions normally associated with controller hardware (speed, wave form, electrical switching, noise). As the emulator will have full control of the voltages and currents supplied to the motor or battery under test, it will provide advanced testing capabilities and power analysis in the high power/high frequency range of operation without requiring additional instrumentation with high fidelity. The HPHFE system's new capabilities for development and testing of electrified powertrain components is transformative for the strategically important automotive sector. **
