A big change is coming to the Tesla Supercharging network in the US (and in North America in general), as the chargers will be opened up to non-Tesla EVs.
We know that the company is trying to open the network to all electric cars globally, which in Europe, is already implemented through a pilot project (in the Netherlands, Norway and France).
At the recent Financial Times Future of the Car event, Tesla CEO Elon Musk confirmed (see at 1:03:40) that to make the network available to other EVs, Tesla will add the industrywide connector (SAE J1772 Combo1/CCS Combo 1 or simply CCS1) as an option.
