Mercedes just announced when its EVs will actually be compatible. It's the traditional method of operating, similar to what others have been doing: owners will be granted an adapter to convert their existing Combined Charging System (CCS) port to the more efficient NACS protocol.

Mercedes-Benz is giving its electric vehicle owners access to Tesla's Supercharger network for public fast charging with approved adapters.

Mercedes-Benz said that its electric vehicles will be able to access Tesla’s Supercharger network starting in February.

US Mercedes-Benz EV drivers will be able to charge their cars at over 20,000 Tesla Superchargers in the US and Canada.

Six non-Tesla EV brands now have more charging options, with Mercedes up next in February. Here's the full list and how this major industry shift came about.

The German automaker's EVs will be able to access a total of 110,000 public charging points across the US and Canada.
