Volkswagen’s Diess wants 40 battery factories in Europe to handle EV overload
Volkswagen knows the future of the automobile industry is electric, and it is doing its best to transition its massive German stronghold into a series of large-scale electric vehicle production facilities. A company that is less than ten years out of a major scandal involving emissions cheat devices, VW is equipped with a new head since the Dieselgate scandal initially broke twelve years ago. Herbert Diess is likely the best man for the job: he’s charismatic, he’s driven, and he knows a thing or two about the auto industry. But most importantly, the man who runs Volkswagen knows that to keep up with the surge in electric vehicle popularity, his company will need more of everything, especially batteries, which he is preparing to produce in massive numbers if the European Union’s Green Deal is approved.
Ten years ago, Diess asked the head of China’s CATL, a battery supplier, if the company would ever transition away from smartphone batteries and toward EV cells. At the time, the answer was no. However, things often change, and CATL is now supplying some batteries for Tesla at Giga Shanghai. CATL’s ability to supply large volumes of batteries, paired with its tendency to innovate, makes it one of the industry’s powerhouses.
And while Diess, who has buddied up with Tesla frontman Elon Musk in the recent years, realizes that batteries are “typically supplier products,” he knows it doesn’t have to be like that. Tesla, which has already established itself as the global leader in electric vehicle development, is beginning to supply its own cells. This not only gives the company an advantage to control the way the batteries are made and the quality of the product itself, but it also reduces prices by a significant margin, 69% in Tesla’s eyes.
Diess realizes that if electric vehicles continue to surge in popularity, Volkswagen will need more, and it will likely have to take the route that Tesla is taking. If the Green Deal goes through, Volkswagen will need an estimated 40 large battery factories on the continent of Europe alone.
“If the EU’s Green Deal goes as it is, the battery factories announced so far in Europe will only cover around five to ten percent of demand. If the Green Deal comes, we will need 40 large battery factories in Europe,” Diess explained.
The Green Deal would maintain that the EU would have around 13 million EVs on the road by 2025. This will bring one million public charging stations to various European markets, solidifying the continent as the most friendly place to drive an electric vehicle globally. That all sounds great and wonderful, but Diess is right: companies are going to need cells.

Volkswagen is in the process of building a battery factory in Salzgitter, Germany, together with Sweden’s Northvolt, Diess said. “This is an innovative, young, and still relatively small company,” and Volkswagen is still in the process of trying to solve the logistics of the whole operation. “That would be a manageable task for the large German suppliers,” Diess added in an interview with WirtschaftsWoche.
Diess’ approach for Volkswagen’s electric future is undoubtedly one that a company with the experience and dedication to automotive manufacturing can figure out. However, transitioning away from what legacy automakers have used for 100 years is proving to be a difficult task, and VW is no exception to the issues that come with building EVs. Although its ID.3 is due to roll out with fully functional software, it wasn’t always like that. Early buyers didn’t have simple functions like Apple CarPlay when they picked up their new EV from the German automaker.
But past the infotainment system, Volkswagen knows that batteries are really the bread and butter of this industry. Build a good cell, or source one, and you’re on your way, as long as you are committed to focusing purely on EVs for the future.

Tesla is updating Cybertruck owners on its timeline of a massive feature that has yet to ship: Powershare with Powerwall.
Powershare is a bidirectional charging feature exclusive to Cybertruck, which allows the vehicle’s battery to act as a portable power source for homes, appliances, tools, other EVs, and more. It was announced in late 2023 as part of Tesla’s push into vehicle-to-everything energy sharing, and acting as a giant portable charger is the main advantage, as it can provide backup power during outages.
Cybertruck’s Powershare system supports both vehicle-to-load (V2L) and vehicle-to-home (V2H), making it flexible and well-rounded for a variety of applications.
However, even though the feature was promised with Cybertruck, it has yet to be shipped to vehicles. Tesla communicated with owners through email recently regarding Powershare with Powerwall, which essentially has the pickup act as an extended battery.
Powerwall discharge would be prioritized before tapping into the truck’s larger pack.
However, Tesla is still working on getting the feature out to owners, an email said:
“We’re writing to let you know that the Powershare with Powerwall feature is still in development and is now scheduled for release in mid-2026.
This new release date gives us additional time to design and test this feature, ensuring its ability to communicate and optimize energy sharing between your vehicle and many configurations and generations of Powerwall. We are also using this time to develop additional Powershare features that will help us continue to accelerate the world’s transition to sustainable energy.”
Owners have expressed some real disappointment in Tesla’s continuous delays in releasing the feature, as it was expected to be released by late 2024, but now has been pushed back several times to mid-2026, according to the email.
Foundation Series Cybertruck buyers paid extra, expecting the feature to be rolled out with their vehicle upon pickup.
Cybertruck’s Lead Engineer, Wes Morrill, even commented on the holdup:
As a Cybertruck owner who also has Powerwall, I empathize with the disappointed comments.
To their credit, the team has delivered powershare functionality to Cybertruck customers who otherwise have no backup with development of the powershare gateway. As well as those with solar…

He said that “it turned out to be much harder than anticipated to make powershare work seamlessly with existing Powerwalls through existing wall connectors. Two grid-forming devices need to negotiate who will form and who will follow, depending on the state of charge of each, and they need to do this without a network and through multiple generations of hardware, and test and validate this process through rigorous certifications to ensure grid safety.”
It’s nice to see the transparency, but it is justified for some Cybertruck owners to feel like they’ve been bait-and-switched.
Tesla has opened its northernmost Supercharger in Fairbanks, Alaska, with eight V4 stalls located in one of the most frigid cities in the U.S.
Located just 196 miles from the Arctic Circle, Fairbanks’s average temperature for the week was around -12 degrees Fahrenheit. However, there are plenty of Tesla owners in Alaska who have been waiting for more charging options out in public.
There are only 36 total Supercharger stalls in Alaska, despite being the largest state in the U.S.
Eight Superchargers were added to Fairbanks, which will eventually be a 48-stall station. Tesla announced its activation today:

The base price per kWh is $0.43 at the Fairbanks Supercharger. Thanks to its V4 capabilities, it can charge at speeds up to 325 kW.
Despite being the northernmost Supercharger in North America, it is not even in the Top 5 northernmost Superchargers globally, because Alaska is south of Norway. The northernmost Supercharger is in Honningsvåg, Norway. All of the Top 5 are in the Scandanavian country.
Tesla’s Supercharger expansion in 2025 has been impressive, and although it experienced some early-quarter slowdowns due to V3-to-V4 hardware transitions, it has been the company’s strongest year for deployments.
🚨🚨 Tesla Supercharging had a HUGE year, and they deserve to be recognized.

Through the three quarters of 2025, the company has added 7,753 stations and 73,817 stalls across the world, a 16 percent increase in stations and an 18 percent increase in stalls compared to last year.
Tesla is on track to add over 12,000 stalls for the full year, achieving an average of one new stall every hour, an impressive statistic.
Recently, the company wrapped up construction at its Supercharger Oasis in Lost Hills, California, a 168-stall Supercharger that Tesla Solar Panels completely power. It is the largest Supercharger in the world.

Tesla shocks with latest Robotaxi testing move
Why Tesla has chosen to use a couple of Model S units must have a reason; the company is calculated in its engineering and data collection efforts, so this is definitely more than “we just felt like giving our drivers a change of scenery.”
Tesla Model S vehicles were spotted performing validation testing with LiDAR rigs in California today, a pretty big switch-up compared to what we are used to seeing on the roads.
Tesla utilizes the Model Y crossover for its Robotaxi fleet. It is adequately sized, the most popular vehicle in its lineup, and is suitable for a wide variety of applications. It provides enough luxury for a single rider, but enough room for several passengers, if needed.
However, the testing has seemingly expanded to one of Tesla’s premium flagship offerings, as the Model S was spotted with the validation equipment that is seen entirely with Model Y vehicles. We have written several articles on Robotaxi testing mules being spotted across the United States, but this is a first:
🚨 Tesla is using Model S vehicles fitted with LiDAR rigs to validate FSD and Robotaxi, differing from the Model Ys that it uses typically
Those Model Y vehicles have been on the East Coast for some time. These Model S cars were spotted in California https://t.co/CN9Bw5Wma8 pic.twitter.com/UE55hx5mdd

Why Tesla has chosen to use a couple of Model S units must have a reason; the company is calculated in its engineering and data collection efforts, so this is definitely more than “we just felt like giving our drivers a change of scenery.”
It seems to hint that Tesla could add a premium, more luxury offering to its Robotaxi platform eventually. Think about it: Uber has Uber Black, Lyft has Lyft Black. These vehicles and services are associated with a more premium cost as they combine luxury models with more catered transportation options.
Tesla could be testing the waters here, and it could be thinking of adding the Model S to its fleet of ride-hailing vehicles.
Reluctant to remove the Model S from its production plans completely despite its low volume contributions to the overall mission of transitioning the world to sustainable energy, the flagship sedan has always meant something. CEO Elon Musk referred to it, along with its sibling Model X, as continuing on production lines due to “sentimental reasons.”
However, its purpose might have been expanded to justify keeping it around, and why not? It is a cozy, premium offering, and it would be great for those who want a little more luxury and are willing to pay a few extra dollars.
Of course, none of this is even close to confirmed. However, it is reasonable to speculate that the Model S could be a potential addition to the Robotaxi fleet. It’s capable of all the same things the Model Y is, but with more luxuriousness, and it could be the perfect addition to the futuristic fleet.
