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

无线充电将极大地促进自主电子交通系统的普及和高效运营。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。无线电能传输(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健壮性。然而，谐振式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(SAEJ2954标准级别II及以上；7.7 kW至22.0 kW)时减少电磁辐射/热损失；以及(3)异物检测和后续故障处理。为了应对上述挑战，拟议的试验台将支持新设计和配置的开发、测试和验证，使电磁干扰/兼容性(EMI/EMC)辐射成为考虑的中心。该设备使用的高级目标具体涉及静态无线快速充电和动态/动态无线充电的EMI/EMC测试。*EMI/EMC测试室将支持开发和全面测试先进的WPT配置和控制技术，用于电子移动和智能建筑/家庭/办公室/城市基础设施等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，在模块化和可重新配置方面为多学科研究人员提供灵活性。整个WPT测试基础设施将位于一个消声室(电磁干扰，兼容EMI)中，它将模拟一个开放区域测试场(OATS)，以消除环境电磁场污染的干扰。一旦在测试舱内进行设计、测试和验证，更大、大功率范围的WPT系统将准备好在安大略省技术-汽车卓越中心(ACE)内建造和测试，并具有真实世界的负载和天气指数。*EMI/EMC测试舱将促进WPT用于自主电子移动/电子交通的商业化和采用的潜力。此外，由于加拿大大部分能源储存和汽车行业位于安大略省，所需设备将位于战略位置，主要行业合作伙伴可以访问。这笔RTI赠款的资金将用于在该大学发展高质量的研究设施，并将把优秀的学生转变为领先的行业专业人员。该集团内部正在进行的研究一直在给加拿大的电动交通领域带来革命性的变化，所需的设备只会进一步促进自主电子移动领域的新的跨学科倡议。

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.**
