CCS2 retrofits: what to install on Model 3/Y and on Model S/X

Model 3/Y

European 3/Y come with a built-in CCS2 port from the factory (all deliveries since 2019): they need no adapter, activation, or retrofit. Retrofitting is relevant for US imports (NACS port): a CCS2→NACS adapter (~$200–300) or swapping the charge port/PLC module for a European one; cars built before ~10.2020 additionally need a charge port ECU retrofit (Gen4).

How it is installed now. Recent firmware has simplified the procedure: on the Model 3/Y and on the 2018 Model S the config no longer has to be written. It is enough to lift the rear seat, plug in two connectors and run a software reinstall, and the car picks the retrofit up by itself, roughly an hour of work. The config still has to be edited only on older S/X. Some shops still bill the old way, around $100 for a "config write" that is no longer part of the procedure (#462709, #462712, #462731, #462764).

Model S/X (EU)

An official CCS2 retrofit is available (connector/module kit). For older S/X, pick the kit by VIN/year.

The kit is chosen by charger unit, not by battery (75/90/100 makes no difference): the charger changed after 06/2016, and the retrofit version depends on exactly that. Which one you have is visible on the sticker under the rear seat. The units differ between S/X and 3/Y, there are EU/US revisions, and pre-facelift versus facelift differ in wiring (#459696, #459697, #459699). First-generation cars (Model S 2014) may carry a gen1 charger that cannot do CCS at all, and then the retrofit also means replacing the charger unit (#482196, #482197).

Budget

≈ $150–500 (adapter / retrofit kit + labor) covers the 3/Y and most S/X.

The worst case is an old Model S 2014: the retrofit itself ~$500 plus ~$100 for the software switch, and if it has a gen1 charger, another ~$1,000 for the charger unit, about $2,000 in total (August 2026 prices) (#482196, #482202, #482205).
