SAE releases new conductive charging norm
SAE International has released the new Norm SAE J3068 in North America for the conductive charging of medium and heavy electric utility vehicles. It resembles the European norm IEC 62196 for type 2 and CCS.
The reason for the update is that North American standards do not support three-phase charging. The charge mode update will also help enhance grid stability at higher power levels. Single phase charging was also previously limited to 19.2 kW.
Many North American locations already had the infrastructure for three phase charging, but can now take advantage of the technology up to 480 V (Or 133 kW at 160A), as well as 600 volt AC (166 kW at 160A).
The move is catching up on the problem that SAE created their J1772 norm as a single phase charging solution, only later adding a DC extension. The standard is now closely comparable to the European solution.
