It is official – Tesla-based plug would be the new federal EV charging commonplace


The Biden administration will formally replace the brand new federal EV charging commonplace to the J3400 based mostly on Tesla’s plug, appearing Federal Freeway Administrator Kristin White introduced Tuesday.

It’s formally the Tesla-based J3400

Unbiased requirements group SAE Worldwide introduced in October that it had launched J3400, the brand new open commonplace based mostly on the Tesla charging expertise. Yesterday, White stated at a convention hosted by the Alliance for Automotive Innovation:

Within the coming weeks, you’ll be seeing an replace from the federal businesses on what we name the J3400 commonplace. That would be the commonplace shifting ahead, and we’re actually completely happy to report that out.

White advised POLITICO that the replace, which can present “clarification” on utilizing flexibilities beneath the prevailing rule, can be accomplished earlier than the Trump administration takes over. The Federal Freeway Administration plans to difficulty FAQs and maintain a webinar on December 17.

Electrek’s Take

That is nice information. As my colleague Jameson Dow defined in a submit final yr, the J3400 charging connector, which is predicated on Tesla’s NACS plug, affords quite a few advantages, so it is sensible because the federal commonplace. Because of SAE’s involvement, it’s now an open commonplace, now not tied to a single automaker.

For instance, the J3400 ought to make set up and charging cheaper and simpler for companies and multifamily dwellings, make charging extra interoperable between industrial and private automobiles, and create new prospects for EV road charging. It’s price studying Jamie’s submit right here.

However how is having a brand new federal commonplace going to have an effect on the Nationwide Electrical Automobile Infrastructure (NEVI) program? NEVI at the moment requires that every federally funded EV charging station will need to have not less than 4 CCS ports that may cost at 150 kW concurrently.

I’m guessing that is the place the flexibleness will are available in – the Biden administration isn’t simply going to trash the CCS port-equipped charging stations which are within the pipeline or are already in place because it phases within the J3400.

Moreover, many people have CCS ports on our automobiles and don’t but have entry to Superchargers. And even once we do get entry, we’ll nonetheless use these CCS chargers.
