In 2020, Tesla announced that a CCS adapter is coming, but it was only initially released in Korea. However, after two long years of waiting, Tesla has finally made the update to its online shop and the adapter is now available for purchase in North America.
The new Tesla CCS Combo 1 adapter is identical to the one that Tesla has been selling in Korea. It offers charging speeds up to 250kW and can be used at third-party charging networks.
According to Tesla:
"The CCS Combo 1 Adapter is compatible with most newer Tesla vehicles, while some vehicles may require a retrofit to ensure functionality with third-party CCS stations. We recommend checking that your vehicle is on the latest available software prior to signing in to your Tesla Account to verify vehicle compatibility"
The problem is with the charging ECU in Tesla vehicles built prior to October 2020. Tesla plans to release a retrofit in early 2023. In order to order the adapter, Tesla owners need to log into their Tesla account so that Tesla knows if their vehicle is compatible. If not, car owners can't even order, as Tesla likely wants to prioritize orders for Tesla owners who don't need the retrofit.
This is great news for Tesla owners in North America, as it means they will now be able to charge their cars more easily. However, it is worth noting that the adapter is not cheap, and it remains to be seen how many public chargers will actually be compatible with it.
