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 owners have long griped about the wireless phone charger in the Model Y and other vehicles. It often turns smartphones into miniature ovens rather than reliably topping them up.
Software engineer and Model Y owner Michał Gapiński tackled this issue head-on with a clever DIY upgrade, swapping the cooled wireless charger pad from the China-made Model YL in for the one that came standard in his vehicle.
There are several key differences between the U.S.-built Model Y’s wireless charging pad and the one that Tesla has been installing in the Model YL. The one installed in U.S.-built vehicles lacks active cooling and relies on basic heat dissipation, leading to rapid temperature buildup during charging. In contrast, the Model YL integrates a small fan for active cooling.

This design maintains lower temperatures even in warm ambient conditions, though it does not support faster Qi2 charging on iPhones. The connector matches exactly, making physical swaps feasible on compatible consoles, but coding is required to enable full functionality.
Owners in the U.S. have complained about the wireless charging pad, with many reporting that overheating is fairly common. Within 20 or 30 minutes of placing a phone on the wireless charging pad, many have reported overheating messages on their phones, which halt charging and essentially turn the pad into a fancy place to rest your phone.
Many owners have opted to simply plug their phones into a charging cord. Tesla has acknowledged the problem by releasing several solutions for owners, including a relatively new feature that allows you to simply turn off the charging and simply act as a holder for your phone while driving.
Gapiński said that he sourced the cooled pad affordably from China, and it cost under $200 for the part.
He removed the existing console charger, swapped in the new unit, confirming a perfect connector fit, and handled the trim differences. Since the parameter isn’t fully secured, he enabled it through custom coding outside official Toolbox.
Connector is identical, she fits, now time to code it. https://t.co/Y9idgDrpCq pic.twitter.com/uwwgq6blg7

The fan activates quietly, blending with AC and seat cooling. He reported the installation was effective and the wireless charging pad worked perfectly; it even kept the phone cool as it stayed at just 86 degrees Fahrenheit. Many times, the wireless charging pad will bring the phone’s temperature well above 100 degrees, sometimes even being relatively hot to the touch.
The retrofit worked, no issues. First Model Y with a cooled wireless charger! No QI2/faster charging on the iPhone but it does not boil the phone even when it is 30 degrees outside.
The fan kicks in, it is not audible especially with the air conditioning and seat cooling. The… https://t.co/JOyR8Tb1Yo pic.twitter.com/kJcYhQIlYq

This retrofit highlighted an elegant, owner-driven solution to a factory shortcoming. It is expected that Tesla will begin installing the cooled charging pads into new cars in the U.S. soon, and hopefully, it will offer some sort of retrofit service or kit to owners here who want to use the charging pad effectively.
For those who love to tinker, it’s an accessible upgrade, proving that innovation thrives beyond the production line.
The Tesla Roadster unveiling could be coming “in a few weeks,” according to the company’s Chief Designer Franz von Holzhausen, who said at the Tesla Takeover Europe Event in Austria that the all-electric hypercar could finally make its way to the production line after years of anticipation.
Von Holzhausen delivered the news just days after The Information reported that Tesla planned to push the Roadster unveiling to August. It was slated for both April and May of this year, but now it seems the company is leaning toward a late Summer event to cap off the heat with perhaps its most anticipated vehicle of all-time.

Franz has been with Tesla since 2008, and has played a pivotal role in the iconic design language the company has utilized with its vehicles. Speaking to the crowd in Austria virtually, von Holzhausen’s comments injected fresh excitement into a project that has been plagued by delays for nine years.
The second-generation Roadster promises to redefine supercar standards. Tesla’s website still highlights ambitious targets: 0-60 mph in under 1.9 seconds (with optional SpaceX thruster pack potentially achieving 1.1 seconds or less), a top speed exceeding 250 mph, and a range of about 620 miles.
Equipped with a tri-motor all-wheel-drive setup delivering over 1,000 horsepower, the four-seater aims to blend blistering acceleration, everyday usability, and innovative features like cold gas thrusters for short-hop capabilities, technology that will combine the project with SpaceX.
But years after the company promised to start production, which was slated for 2020, the timeline for the Roadster has continued to shift.
Tesla has strung along those who have put $50,000 deposits down, as well as fans and enthusiasts of the company who have been long awaiting the company to bring forth a car truly designed for the human driver, and not autonomy. The Roadster is more than just a halo vehicle for Tesla; it showcases the company’s ability to push the boundaries while incorporating synergies from other Musk companies.
However, it has to make it to production, which is something Musk and Co. have pushed back repeatedly.
As Tesla navigates Robotaxi development and broader autonomy goals, the Roadster serves as a reminder of its performance roots. If von Holzhausen’s timeline holds, fans could witness this engineering marvel by late June or early July 2026. Whether a full unveiling, demo, or initial deliveries, it marks a milestone for electric supercars.
Tesla has reportedly pushed the unveiling of the Roadster once again, but there are also evidently new details about the event that the company plans to show off.
The Information reported this morning that Tesla will now unveil, for the second time, the next-generation Roadster in August, a further delay from the multiple timeline that the company had previously stated.
The report has not been confirmed or denied by Tesla at any capacity.
It also states the unveiling event will take place in Texas, the same place that Tesla executives revealed in May would be the place of manufacture for the company’s highly-anticipated supercar, which boasts a top speed of over 250 MPH and 650 miles of range, according to its website.
Tesla is also expected to showcase the SpaceX package, which will be used for faster acceleration and potentially hovering capabilities, at the unveiling event, the report states. Musk has always planned for this to happen, but now it seems it is more realistic than ever

The Roadster has had its unveiling date and manufacturing date pushed back on many occasions. It was set to start production in 2020, but the COVID-19 pandemic crippled supply chain operations, forcing Tesla to push its timeline back considerably.
However, COVID has been over for some time, and Tesla has still not managed to successfully schedule and execute an unveiling event, which is something fans and enthusiasts, as well as those who have put down a $50,000 deposit, have been waiting for.
The vehicle was close to completion last year, but Musk truly wanted Lars Moravy and Franz von Holzhausen to push the limits of the Roadster. In July of last year, Moravy said:
“Roadster is definitely in development. We did talk about it last Sunday night. We are gearing up for a super cool demo. It’s going to be mind-blowing; We showed Elon some cool demos last week of the tech we’ve been working on, and he got a little excited.”
It is important to note two things: Tesla has not confirmed these details, and the company has regularly pushed these dates back. Until Tesla sends out formal invitations with a concrete date, taking any unveiling event reports with a grain of salt is a good idea.
