Society of Automotive Engineers Is Standardizing Tesla’s EV Charging Plug

The Society of Automotive Engineers, a U.S.-based standards organization known as SAE International, announced plans to support Tesla’s EV “North American Charging Standard” or NACS port. “SAE’s adoption will make it easier for electric vehicle charging station manufacturers and operators to implement the port while also making charging for EV owners more consistent and reliable,” reports The Verge. From the report: Tesla’s formerly proprietary charging port was opened up last year in a bid to become the de facto EV standard in the US. The US Joint Office of Energy and Transportation has worked with Tesla and the SAE in an effort to expedite the Tesla plug as a standard to improve the country’s charging infrastructure.

SAE is also working with the ChargeX consortium, which was put together by the Biden administration so the Department of Energy’s National Labs can help EV manufacturers create consistent tech across vehicles and chargers for items like universal error codes. SAE is lending its Public Key Infrastructure (PKI) technology to make charging more secure against cyber attacks. Also today, ChargePoint announced that customers setting up charging stations with its equipment could add Tesla’s port standard to new orders of several commercial AC stations and DC fast chargers, as well as home AC charging systems later this year (via Electrek).

ChargePoint joins a handful of similar electric vehicle charging station companies that have announced support for Tesla’s charging port. The standard has been gaining momentum since major legacy automakers Ford, GM, and Rivian all announced commitments to add Tesla’s plug to their future vehicles. […] Now, with SAE supporting NACS, larger EV charging company holdouts like the Volkswagen-owned Electrify America may have an easier time making the jump.
