SS1： Advanced Wireless Power Transfer for Electric Vehicles

Abstract:

Since the Society of Automobile Engineers (SAE) launched the industry-wide specification guideline J2954 for wireless charging of light duty electric and plug-in electric vehicles (EVs), research activities on interoperability, electromagnetic compatibility, minimum performance, safety and testing of wireless power transfer (WPT) in EVs are intensified over the last few years. The current version of SAE TIR J2954 only addresses the unidirectional charging from grid to vehicle, while the bidirectional energy transfer is not covered. The guideline J2954 calls for an operating frequency of 85 kHz and power levels of 3.7 kW, 7.7 kW, 11.0 kW and 22.0 kW, but other operating frequencies and power levels (e.g., above 50 kW) are not discussed. Besides, safety issues, such as human exposure to electromagnetic fields, are not included in the proposal. This special session will focus on the emerging WPT technologies to solve the current and future issues of WPT in EVs.

Topics of this special session include, but not limited to the following:

  • Static charging for pure EVs and plug-in hybrid EVs
  • Dynamic charging for road-powered EVs (RPEVs)
  • Inductive power transfer, capacitive power transfer and hybrid power transfer
  • Modular WPT systems
  • Advanced positioning technologies
  • Multi-physics field design optimization
  • Foreign object detection
  • Wireless machine drives
