A CUSTOMIZED ELECTROMAGNETIC INTERFERENCE/COMPATIBILITY (EMI/EMC) TEST CHAMBER FOR TESTING AND VALIDATION OF WIDE-RANGING WIRELESS POWER TRANSFER SYSTEMS

无线充电肯定会使自动电子交通系统的接受和有效运行得以推进。无线充电的最大贡献将是通过促进机会充电来扩大电子交通的范围。无线电力传输（WPT）的两种主要技术选择是磁感应和磁共振。磁共振是首选技术，因为它在大分离和未对准条件下具有鲁棒性。然而，谐振WPT面临的持续问题和关键挑战包括：（1）未对准条件下的效率;（2）在高功率传输水平（SAEJ 2954标准II级及以上; 7.7 kW至22.0 kW）下减少电磁辐射/热损耗;以及（3）异物检测和后续故障处理。为了应对上述挑战，拟议的测试台将使新设计和配置的开发，测试和验证保持电磁干扰/兼容性（EMI/EMC）辐射的考虑中心。设备使用的高级别目标特别涉及静态无线快速充电和运动/动态无线充电的EMI/EMC测试。* EMI/EMC测试室将能够开发和全面测试先进的WPT配置和控制技术，用于电动汽车和智能建筑/家庭/办公室/城市基础设施的各种电动自主模式的无线充电。这种独一无二的即插即用型基础设施将由模块化模块组成，为多学科研究人员提供模块化和可重新配置的灵活性。整个WPT测试基础设施将位于消声室（电磁干扰，EMI兼容）中，该消声室将模拟开放区域测试场地（OATS），以消除环境电磁场污染的干扰。一旦在测试室中设计、测试和验证，更大、更宽功率范围的WPT系统将准备在安大略汽车技术卓越中心（ACE）内建造和测试，并使用真实世界的负载和天气指数。EMI/EMC测试室将提升WPT在自动电动汽车/电动交通领域的商业化和采用潜力。此外，由于加拿大大部分储能和汽车行业位于安大略，因此所要求的设备将位于战略位置，可供主要行业合作伙伴使用。该RTI赠款的资金将用于在大学开发高质量的研究设施，并将优秀的学生转化为领先的行业专业人士。该集团内部正在进行的研究一直在彻底改变加拿大的电动交通领域，所要求的设备只会进一步促进自主电动汽车领域的新的跨学科举措。

Wireless charging will most definitely enable acceptance and efficient operation of autonomous e-transportation systems moving forward. The biggest contribution of wireless charging would be in extending the range of e-transportation, by facilitating opportunity charging. The two main technology alternatives for wireless power transfer (WPT) are magnetic induction and magnetic resonance. Magnetic resonance is the preferred technology, due to its robustness under large separation and misalignment conditions. However, the ongoing issues and key challenges faced by resonant WPT include: (1) Efficiency under misaligned conditions; (2) Reduction of electromagnetic radiation/thermal losses at high power transfer levels (SAEJ2954 Standard Level-II and above; 7.7 kW to 22.0 kW); and (3) Foreign object detection and subsequent fault handling. In order to address the above challenges, the proposed test-bench will enable development, testing, and verification of new designs and configurations keeping electromagnetic interference/compatibility (EMI/EMC) radiations at the center of consideration. The high-level goals of the usage of the equipment are specifically related to EMI/EMC testing for both static wireless fast charging and in-motion/dynamic wireless charging.***The EMI/EMC test-chamber will enable the development and comprehensive testing of advanced WPT configurations and control techniques for wireless charging of a wide range of electric autonomous modes of e-mobility and smart building/home/office/city infrastructure. This one-of-a-kind, plug-and-play type infrastructure will be made up of modular blocks, offering flexibility to multi-disciplinary researchers in terms of modularity and re-configurability. The entire WPT test infrastructure will sit in an anechoic (electromagnetic interference, EMI-compatible) chamber, which will emulate an open area test site (OATS) to eliminate interference from environmental electromagnetic field pollution. Once designed, tested, and validated within the test chamber, larger, wide-power-ranging WPT systems will be ready to be built and tested within the Ontario Tech-Automotive Center of Excellence (ACE), with real-world loads and weather indices.***The EMI/EMC test chamber will advance the potential for commercialization and adoption of WPT for autonomous e-mobility/e-transportation. Also, since most of the Canadian energy storage and auto industry is located in Ontario, the requested equipment will be strategically located, accessible to key industry partners. The funding from this RTI grant will be used to develop high-quality research facilities at the university and will transform exceptional students into leading industry professionals. The research being performed within the group has been consistently revolutionizing the field of electric transportation in Canada, and the requested equipment will only further foster novel interdisciplinary initiatives in the areas of autonomous e-mobility.**
