A Tesla Supercharger near Oslo appears to be the first in Europe to use the company’s new V4 power cabinet, the upgrade that enables charging speeds of up to 500 kilowatts.
The site, at Hellerudsletta outside the Norwegian capital, was identified on Saturday by EV-focused content creator and X user William Jarbeaux.
He said he had confirmed the hardware from the station’s plaque and dispenser specifications, and that the cabinet appeared to have been built at Tesla‘s factory in Buffalo, New York.
The distinction matters because Tesla has used the “V4” label loosely for years.
Tesla began rolling out V4 charging posts — the visible stalls, with longer cables and screens designed to suit non-Tesla cars — in Europe in early 2023, starting in Harderwijk, the Netherlands.
However, those posts were wired to older V3 power cabinets that cap output at around 250 kW, a configuration the community calls “V3.5.”
Jarbeaux said the Dutch site remained a V3.5 that could not charge above 500 volts, whereas the Norwegian station uses the genuine V4 cabinet.
Tesla, which disbanded its media-relations team in 2024, has not formally announced the site and did not respond to a request for comment.
What the V4 cabinet changes
The V4 cabinet, announced in November 2024, is the part of the upgrade that raises performance.
A single cabinet can deliver up to 1.2 megawatts shared across as many as eight stalls, with each stall capable of up to 500 kW for cars and the cabinet supporting battery systems up to 1,000 volts.
The figures compare with 250 kW per stall and a roughly 500-volt ceiling on the V3 generation.
The first complete V4 station anywhere opened in Redwood City, California, in September 2025.
Currently, only a handful of true 500 kW sites were operating, almost all of them in the United States, making the Norwegian station an early marker of the technology’s arrival in Europe.
For now, few cars can use the full speed.
Tesla‘s mainstream Model 3, S, X and Y still draw about 250 kW, and only the high-voltage Cybertruck and some 800-volt vehicles from other brands can approach the 500 kW peak.
A deliberate European push
Tesla‘s Gigafactory New York stopped building V3 cabinets last March, after more than 15,000 units over seven years, and switched fully to V4 production.
The company has said the V4 cabinet will be the standard for all new Supercharger sites in Europe, with upgrades to existing stations in France, the Netherlands and Britain expected in the second half of the year.
Tesla has also begun shipping a pre-assembled “folding” version of the V4 station to Europe to speed installation, with the first unit appearing in the region this month and a wider rollout to motorway rest stops planned for the third quarter.
Norway has the highest EV adoption rate in the world (about 97%), and Tesla has repeatedly used it to launch new charging hardware before expanding elsewhere on the continent.
The Supercharger network passed 80,000 stalls globally earlier this year and is increasingly being opened to rival brands, including Ford, General Motors, Rivian, Hyundai and, most recently, several Stellantis marques.
