This SAE Recommended Practice covers the general physical, electrical, functional and performance requirements to facilitate conductive charging of EV/PHEV vehicles in North America. This document defines a common EV/PHEV and supply equipment vehicle conductive charging method including operational requirements and the functional and dimensional requirements for the vehicle inlet and mating connector.
This recommended practice redefines AC Level 1 and AC Level 2 charge levels and specifies a new conductive charge coupler and electrical interfaces for AC Level 1 and AC Level 2 charging. The coupler and interfaces for DC charging are currently being developed and will be added to this document upon completion. Adoption of multiple standard charge couplers based on charge level will enable selection of an appropriate charge coupler based on vehicle requirements thus allowing for better vehicle packaging, reduced cost, and ease of customer use.
