Tesla’s V4 Supercharger appeared in new project plans for a site in Danvers, Massachusetts, with a design that is strikingly similar to the company’s 72 kW Urban Supercharger. However, project details outlined in blueprints for the Danvers Supercharger seem to indicate this is Tesla’s next big development in its next-gen charging posts, but some questions still remain.
Tesla’s V4 Supercharger
Tesla’s V4 Supercharger will, of course, succeed the 250 kW-capable V3 Superchargers that were released in 2019. The V3 Supercharger was an outrageous update and a huge development to the expedited process of charging Tesla’s EVs. Rates of up to 1,000 miles of range added per hour are capable with the V3 Superchargers, but they are also only available to Tesla vehicles, which is where the V4 may be coming into play.
Along with the rumored CSS support that the V4 Supercharger will pack, Tesla seems to be revising a recently-released 72 kW Urban Supercharger design for the new stalls. In the project outline for the Danvers, Massachusetts Supercharger, the design for the “Alternative Supercharger Post” is strikingly similar, but there are a few details that lead us to believe this is what Tesla is planning to utilize for the new design.
Tesla’s Urban Supercharger can be wall-mounted and installed virtually anywhere
Initially, the Alternative design in the blueprints is massive: 6′ 4.5″, weighing 200 pounds. That’s significantly larger than the Urban Supercharger, which is compact and perhaps only four feet or less in height. It towers over the V3 Supercharger design, which is also present in the blueprints and seems to be the project’s more-likely outfitting when it is complete (courtesy of @JH_Beford on Twitter).

We recently reported on some rumors surrounding the V4 Supercharger design, and it does appear to be somewhat similar from a very elementary perspective to what descriptions of the new shell would be. However, there are some things that still remain in question as the V4 Supercharger design has not yet been made public by Tesla.
CCS Support
The project design lacks any mention of potential CCS Support on the V4 Supercharger, which is what most people would expect moving forward from Tesla. The automaker has been utilizing a Pilot Program in Europe that allows other EV brands to utilize Supercharger stalls. This project is available in sixteen countries in Europe, and Tesla has made it clear that, eventually, the capability will be available in the United States. For now, it is too much of an advantage as Tesla continues to grow, and the company keeps it exclusive to Tesla vehicles in the U.S.
However, as we are already a month into the second half of 2022, it gives Tesla less time to roll out the “new Supercharger equipment that will enable non-Tesla EV drivers in North America to use Tesla Superchargers.” These quoted words come courtesy of the White House.
CCS Support may not be on these designs for several reasons, and it could be that Tesla simply hasn’t finalized a design for that Supercharger. Additionally, this could be an entirely different design altogether, and while it could be the V4 Supercharger, Tesla may not have plans to put CCS Support on the V4. That could perhaps be saved for another design.
900v Architecture
Tesla’s V4 Supercharger will also likely support ultra-fast charging architectures like a rumored 900V setup for the Cybertruck. These higher-voltage architectures enable ultra-fast charging and can supply high-performance or high-workload vehicles with range in short amounts of time.
Tesla is also likely to head toward a 350 kW charging rate, which is present in Electrify America chargers. These chargers are perfect for high-voltage vehicles as they can charge vehicles faster, and most importantly, the vehicles can support them. Their higher voltage architecture can stabilize the charging process for these higher-powered chargers. The Porsche Taycan has an 800v architecture, which enables faster charging, less weight, and high performance, all at lower temperatures.

SpaceX secures win as US labor board drops oversight case
The NLRB confirmed that it no longer has jurisdiction over SpaceX.
SpaceX scored a legal victory after the National Labor Relations Board (NLRB) decided to dismiss a case which accused the company of terminating engineers who were involved in an open letter against founder Elon Musk.
The NLRB confirmed that it no longer has jurisdiction over SpaceX. The update was initially shared by Bloomberg News, which cited a letter about the matter it reportedly reviewed.
In a letter to the former employees’ lawyers, the labor board stated that the affected employees were under the jurisdiction of the National Mediation Board (NMB), not the NLRB. As a result, the labor board stated that it was dismissing the case.
As per Danielle Pierce, a regional director of the agency, “the National Labor Relations Board lacks jurisdiction over the Employer and, therefore, I am dismissing your charge.”
The NMB typically oversees airlines and railroads. The NLRB, on the other hand, covers most private-sector employers, as well as manufacturers such as Boeing.
The former SpaceX engineers have argued that the private space company did not belong under the NMB’s jurisdiction because SpaceX only offers services to “hand-picked customers.”
In an opinion, however, the NMB stated that SpaceX was under its jurisdiction because “space transport includes air travel” to get to outer space. The mediation board also noted that anyone can contact SpaceX to secure its services.
SpaceX had previously challenged the NLRB’s authority in court, arguing that the agency’s structure was unconstitutional. Jennifer Abruzzo, the NLRB general counsel under former United States President Joe Biden, rejected SpaceX’s claims. Following Abruzzo’s termination under the Trump administration, however, SpaceX asked the labor board to reconsider its arguments.
SpaceX is not the only company that has challenged the constitutionality of the NLRB. Since SpaceX filed its legal challenge against the agency in 2024, other high-profile companies have followed suit. These include Amazon, which has filed similar cases that are now pending.

Tesla accuses IG Metall member of secretly recording Giga Berlin meeting
The union has denied the electric vehicle maker’s allegations.
Police seized the computer of an IG Metall member at Tesla Giga Berlin on Tuesday amid allegations that a works council meeting was secretly recorded.
The union has denied the electric vehicle maker’s allegations.
In a post on X, Gigafactory Berlin plant manager André Thierig stated that an external union representative from IG Metall attended a works council meeting and allegedly recorded the session. Thierig described the event as “truly beyond words.”
“What has happened today at Giga Berlin is truly beyond words! An external union representative from IG Metall attended a works council meeting. For unknown reasons he recorded the internal meeting and was caught in action! We obviously called police and filed a criminal complaint!” Thierig wrote in his post on X.
Police later confirmed to local news outlet rbb24 that officers did seize a computer belonging to an IG Metall member at the Giga Berlin site on Tuesday afternoon. Tesla stated that employees had contacted authorities after discovering the alleged recording.
IG Metall denied Tesla’s accusations, arguing that its representative did not record the meeting. The union alleged that Tesla’s claim was simply a tactic ahead of upcoming works council elections.
The next works council election at Giga Berlin is scheduled for March 2 to 4, 2026. The facility’s management had confirmed the dates to local news outlets. The official announcement marks the start of the election process and campaign period.
Approximately 11,000 employees are eligible to participate in the vote.
The previous works council election at the plant took place in 2024, and it was triggered by a notable increase in workforce size. Under German labor law, regular works council elections must be held every four years between March 1 and May 31.

Elon Musk’s xAI plants flag in Bellevue AI hotspot
The lease places xAI’s new office in one of the region’s fastest-growing tech hubs.
Elon Musk’s artificial intelligence company xAI has leased a full floor at Lincoln Square South in downtown Bellevue, WA, as per city permit filings.
The lease places xAI’s new office in one of the region’s fastest-growing tech hubs.
Public records indicate that xAI leased roughly 24,800 square feet in Lincoln Square South. The location was previously occupied by video game company Epic Games. Lincoln Square South is part of the Bellevue Collection, which is owned by Kemper Development Co.
The lease was first referenced in January by commercial real estate firm Broderick Group, which noted that an unnamed tenant had secured the space, as stated in a report from the Puget Sound Business Journal. Later filings identified xAI as the occupant for the space.
xAI has not publicly commented on the lease.
xAI hinted at plans to open an office in the Seattle area back in September, when the startup posted job openings with salaries ranging from $180,000 to $440,000. At the time, the company had narrowed its location search to cities on the Eastside but had not finalized a lease.
xAI’s Bellevue expansion comes as Musk continues consolidating his businesses. Last week, SpaceX acquired xAI in a deal that valued the artificial intelligence startup at $250 billion. SpaceX itself is now valued at roughly $1.25 trillion and is expected to pursue an initial public offering (IPO) later this year.
Musk already has a significant presence in the region through SpaceX, which employs about 2,000 workers locally. That initiative, however, is focused largely on Starlink satellite development.
Bellevue has increasingly become a center for artificial intelligence companies. OpenAI has expanded its local office footprint to nearly 300,000 square feet. Data infrastructure firms such as Crusoe and CoreWeave have also established offices downtown.
