What is the official name of Tesla's proprietary charging connector as of 2022?

The official name of Tesla’s proprietary charging connector in 2022 was the North American Charging Standard.

Tesla announced the name on November 11, 2022, when it opened its connector design to other vehicle manufacturers and charging-network operators. The compact connector supports both alternating-current charging and direct-current fast charging through the same physical inlet, unlike CCS arrangements that use a separate lower pair of DC pins.

Before the announcement, the hardware was commonly called the Tesla connector or Tesla charging connector. Tesla’s renaming reflected its attempt to turn a proprietary design into an openly available North American charging standard. The designation is usually shortened to NACS.

NACS is easy to confuse with CCS, CHAdeMO, or Type 2. CCS was the main competing fast-charging system in North America, CHAdeMO originated in Japan, and Type 2 is widely used for AC charging in Europe. The connector later entered the SAE standards process as SAE J3400, but that formal designation came after Tesla’s 2022 announcement.
