NACS EV AC Charging Couplers
Electric vehicle (EV) AC charging couplers that use the North American Charging Standard (NACS) are now available to all electric vehicle manufacturers from Volex.
Volex manufactures authentic NACS charging cables designed for AC charging applications up to 48A, offering both 32/40A for portable charging and 48/50A for wall charging applications. UHF comes standard with option to disable. These EV charging cables meet the NACS specification relevant to the EV market segment.
About the North American Charging Standard (NACS)
NACS is the Tesla-developed specification for charging connectors. Tesla made the NACS standard available for all EV manufacturers to use in November 2022. In June 2023, SAE International announced that it was standardizing NACS as SAE J3400.
