Why CCS2 Became Europe's Standard
The European Union mandated CCS2 (Combined Charging System 2) on all public fast chargers from 2025. This wasn't just a technical preference — it was a strategic policy move to guarantee interoperability across the continent.
CCS2 combines an AC Type 2 connector with DC fast-charging pins in a single housing. Today the vast majority of European vehicles — VW ID series, BMW iX, Hyundai IONIQ 6, Mercedes EQS — ship with a CCS2 inlet.
The Rise of NACS and Its European Impact
The North American Charging Standard (NACS), designed by Tesla and standardised as SAE J3400 in 2022, became the de-facto standard in North America after Ford, GM, Rivian, Honda and others announced adoption from the 2025 model year.
In Europe, however, Tesla opened its Supercharger network via CCS2 adapters, and European Model 3 / Model Y variants ship with CCS2 inlets. This means NACS poses no short-term threat in Europe.
KolayCharge Perspective
According to the KolayCharge Compat database, 94% of vehicles sold in the European market are CCS2 compatible. The number of NACS-equipped vehicles in the EU market is currently near zero. This picture is unlikely to change before 2027.
