Tesla open-sources its connector to take on CCS with 'half the size twice the power' North American Charging Standard

In a surprise move, Tesla opened its proprietary charging port and connector schematics for all EV makers and charging networks to employ at will. The open-sourced design and specification documents call the heretofore custom connector the North American Charging Standard as Tesla argues it is 'half the size, twice as powerful' in comparison with CCS.

[...] Its connector supports up to 1 MW DC output "in one slim package," continues Tesla, and the combination with the port on its vehicles will from now on be called the North American Charging Standard (NACS) in an apparent move to slow the proliferation of the CCS one that other EVs use.

The open-sourcing of Tesla's unique charging system may also have something to do with the government's requirements for CCS-compatible Superchargers on a planned nationwide network that will be built with billions in federal subsidies. According to the Infrastructure Investment and Jobs Act under which said billions are about to be disbursed, "electric vehicle charging infrastructure installed using funds provided under this title shall provide, at a minimum... non-proprietary charging connectors that meet applicable industry safety standards... and open access to payment methods that are available to all members of the public..."
