Title: Wireless Charging of Electric and Plug-in Hybrid Vehicles

Issuing Committee:
Hybrid - Ev Committee

Scope:
- Establishes minimum performance and safety criterea for wireless charging of electric and plug-in vehicles. Team to create a technology matrix to initially evaluate multiple technologies (Inductive, Magnetic resonance, etc.) and end up on common approach. -Charging Locations: Residential, On-Road (Parking Lot, Roadway) -Level 1,2,3 Charging

Rationale:
The current SAE Standard SAE J1772 establishes the wired charging standard. In order to give the customer an option to safety charge their vehicle also wirelessly, a TIR is to be created. The advantages that wireless charging gives the customer are as follows: -Customer transparency and seamlessness for EV/PHEV charging without having to physically connect. -Smart Grid programmability -Global Harmonization for wireless power transfer standard (SAE as a focal point) -Wireless vehicle to Grid communications (coordinated with other SAE committees) This TIR defines acceptable criteria for minimum performance, safety and testing for wireless charging of electric and plug-in electric vehicles. It establishes AC Level 1, AC Level 2 and DC Level 3 charge levels and specifies a location for wireless charging. Adoption of a standard for wireless power transfer based on charge level will enable selection of an appropriate charging based on vehicle requirements thus allowing for better vehicle packaging, reduced cost, and ease of customer use.
