NACS EV DC Charging Couplers
Electric vehicle (EV) DC charging couplers that use the North American Charging Standard (NACS) are now available to all electric vehicle manufacturers from Volex.
Volex NACS charging cables designed for DC charging applications up to 350A. The NACS specification relevant to the EV market segment is met by these EV charging cables.
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 2023. In June 2023, SAE announced that it was standardizing NACS as SAE J3400.
