Battle of the EV Charging Standards: Tesla’s NACS vs. CCS2 vs. CHAdeMO – Who Will Rule the Roads in 2025?
Tesla’s NACS charging connector, introduced in 2012 and opened to other automakers in late 2022, was standardized as SAE J3400 in 2023. By 2025, most major North American automakers committed to NACS for U.S. models, with dual adapters for CCS compatibility. Europe requires CCS2 for fast charging, and Tesla updated its European vehicles accordingly. CHAdeMO is now largely limited to Japan.
