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 defines AC Level 1 and AC Level 2 charge levels and specifies a conductive charge coupler and electrical interfaces for AC Level 1 and AC Level 2 charging. This revision incorporates DC charging. DC Level 1 and DC Level 2 charge levels, charge coupler and electrical interfaces are defined. The DC Level 1 charge coupler is identical to the AC Level 1 and AC Level 2 charge coupler. DC Level 2 charging is achieved by adding 2 high current contacts to the AC Level 1 and AC Level 2 charge coupler.
