SAE International releases new specification (SAE J3068) for conductive charging of medium- and heavy-duty electric vehicles

SAE International’s recommended practice for plug-in charging of medium- and heavy-duty EVs has been approved and published.

J3068: Electric Vehicle Power Transfer System Using a Three-Phase Capable Coupler” was developed from existing international standards, which were extended to cover higher North American grid voltages and higher power levels. J3068 allows vehicles to utilize fully three-phase AC power where it is available and preferred, such as at commercial and industrial locations.

J3068 was developed in a consensus process by SAE International’s Medium and Heavy Duty Vehicle Conductive Charging Task Force Committee, which today is comprised of over 100 global experts from the automotive industry, utilities, charging equipment manufacturers, national laboratories, and academia.
