Tesla Giga Berlin’s 4680 supply won’t start in Germany, and it was never supposed to
Tesla’s plans for the initial battery needs and efforts at Giga Berlin were answered in late 2020 by the automaker during the Q3 Earnings Call. While things tend to change on a somewhat regular basis as far as plans for something as large as a vehicle manufacturing plant, Tesla knew that its initial battery fulfillment plans likely wouldn’t come from the planned Giga Berlin 4680 cell production lines. Instead, Tesla will rely on its Kato Road facility in Northern California, where the development and manufacturing of a new, revolutionary electric vehicle battery is taking place. Tesla also plans to utilize strong relationships with its battery cell manufacturers to solve supply concerns during Giga Berlin’s early production dates.
Concerns regarding Tesla’s planned timeline for Giga Berlin have arisen over the past several days, especially after a German media outlet said that CEO Elon Musk was extending the beginning of the German plant’s EV production efforts to January 2022. While the Giga Berlin timeline remains uncertain as far as the exact starting date, those close to the situation, including Brandenburg Economic Minister Jörg Steinbach, told Teslarati yesterday that production should begin in late Summer or early Fall 2021.
EXCLUSIVE: Tesla Giga Berlin isn’t facing a 6-month delay: German Minister
The concerns about Tesla Giga Berlin’s initial production date started to appear around the same time that reports began to surface about Tesla adding the 4680 battery manufacturing unit plans to its application. German regulators take a deliberate and somewhat extended time for large projects, as so many different factors are considered before anything is given ultimate approval. Some indicated that this extensive regulatory process would delay the production efforts altogether. Still, local sources in Germany have clarified that this only prolongs the project altogether and doesn’t have much of an effect on the start of production. The project will just take longer to complete considering Tesla added another element to the Giga Berlin offensive.
As previously mentioned, the addition of the 4680 line to the application likely caused confusion over whether the Tesla Giga Berlin production lines would activate on time. 4680 production at Berlin will not begin before or at the same time as Tesla’s vehicle production at the German plant. However, Tesla’s plans were never to have the Berlin 4680 lines handle the initial vehicle production at the plant. Tesla originally planned for the Kato Road 4680 lines to supply Giga Berlin with cells when they are available.
Drew Baglino, Tesla’s Senior Vice President of Powertrain and Energy Engineering, said during the Q3 2020 Earnings Call:
“We will incorporate 4680 design solutions into many applications in time across both energy and vehicle, and we can use our pilot production facility in Fremont to support the new factory in Berlin as it ramps.”
Additionally, Tesla’s battery suppliers are being called upon to assist in the initial efforts at Giga Berlin.
Musk announced during the most recent Q1 2021 Earnings Call that Tesla is about 12-18 months away from volume production of 4680 cells. While Tesla may be slightly behind schedule regarding the production of the new 4680 battery, there is no indication that it will delay Giga Berlin’s production altogether. In fact, Musk also acknowledged that its suppliers, who Tesla shares “very strong partnerships” with would be called upon to supply cells “as much as they possibly can.”
Musk said:
“…It appears as though we’re about 12 — probably not more than 18 months away from volume production of the 4680. Now at the same time, we are actually trying to have our cell supply of partners ramp up their supply as much as possible. So this is not something that is to the exclusion of suppliers. It is in conjunction with suppliers. So we want to be super clear about that. This is not about replacing suppliers. It is about supplementing the suppliers. So…and we have a very strong partnership with CATL, with Panasonic and LG. And we would…our request to our strategic partners for cell supply is, please make us…please supply us with as much as you possibly can. Provided the price is affordable, we will buy everything that they can make.”
This includes CATL, a Chinese battery producer who manufactures LFP cells for the Standard Range+ Model 3 at Giga Shanghai. CATL began the construction of a cell manufacturing facility in Germany in 2019. LG Chem also started the construction of an EV battery cell manufacturing facility in Poland in 2017, which could be used to supplement Tesla’s battery efforts in Germany. These suppliers have both assisted Tesla with cells in the past, and these companies will likely supplement Tesla’s needs at Giga Berlin, as Musk requested during the Q1 2021 Earnings Call.
Tesla has been aware that the 4680 lines in Berlin will not take care of the initial production phases at the factory. Instead, it will rely on suppliers and its Kato Road 4680 lines in the United States to take care of the first months of production at Giga Berlin.

Tesla Cybercab spotted with interesting charging solution, stimulating discussion
The port is located in the rear of the vehicle and features a manual door and latch for plug-in, and the video shows an employee connecting to a Tesla Supercharger.
Tesla Cybercab units are being tested publicly on roads throughout various areas of the United States, and a recent sighting of the vehicle’s charging port has certainly stimulated some discussions throughout the community.
The Cybercab is geared toward being a fully-autonomous vehicle, void of a steering wheel or pedals, only operating with the use of the Full Self-Driving suite. Everything from the driving itself to the charging to the cleaning is intended to be operated autonomously.
But a recent sighting of the vehicle has incited some speculation as to whether the vehicle might have some manual features, which would make sense, but let’s take a look:
🚨 Tesla Cybercab charging port is in the rear of the vehicle!
Here’s a great look at plugging it in!!

The port is located in the rear of the vehicle and features a manual door and latch for plug-in, and the video shows an employee connecting to a Tesla Supercharger.
Now, it is important to remember these are prototype vehicles, and not the final product. Additionally, Tesla has said it plans to introduce wireless induction charging in the future, but it is not currently available, so these units need to have some ability to charge.
However, there are some arguments for a charging system like this, especially as the operation of the Cybercab begins after production starts, which is scheduled for April.
Wireless for Operation, Wired for Downtime
It seems ideal to use induction charging when the Cybercab is in operation. As it is for most Tesla owners taking roadtrips, Supercharging stops are only a few minutes long for the most part.
The Cybercab would benefit from more frequent Supercharging stops in between rides while it is operating a ride-sharing program.
Tesla wireless charging patent revealed ahead of Robotaxi unveiling event
However, when the vehicle rolls back to its hub for cleaning and maintenance, standard charging, where it is plugged into a charger of some kind, seems more ideal.
In the 45-minutes that the car is being cleaned and is having maintenance, it could be fully charged and ready for another full shift of rides, grabbing a few miles of range with induction charging when it’s out and about.
Induction Charging Challenges
Induction charging is still something that presents many challenges for companies that use it for anything, including things as trivial as charging cell phones.
While it is convenient, a lot of the charge is lost during heat transfer, which is something that is common with wireless charging solutions. Even in Teslas, the wireless charging mat present in its vehicles has been a common complaint among owners, so much so that the company recently included a feature to turn them off.
Production Timing and Potential Challenges
With Tesla planning to begin Cybercab production in April, the real challenge with the induction charging is whether the company can develop an effective wireless apparatus in that short time frame.
It has been in development for several years, but solving the issue with heat and energy loss is something that is not an easy task.
In the short-term, Tesla could utilize this port for normal Supercharging operation on the Cybercab. Eventually, it could be phased out as induction charging proves to be a more effective and convenient option.

Tesla confirms that it finally solved its 4680 battery’s dry cathode process
The suggests the company has finally resolved one of the most challenging aspects of its next-generation battery cells.
Tesla has confirmed that it is now producing both the anode and cathode of its 4680 battery cells using a dry-electrode process, marking a key breakthrough in a technology the company has been working to industrialize for years.
The update, disclosed in Tesla’s Q4 and FY 2025 update letter, suggests the company has finally resolved one of the most challenging aspects of its next-generation battery cells.
Dry cathode 4680 cells
In its Q4 and FY 2025 update letter, Tesla stated that it is now producing 4680 cells whose anode and cathode were produced during the dry electrode process. The confirmation addresses long-standing questions around whether Tesla could bring its dry cathode process into sustained production.
The disclosure was highlighted on X by Bonne Eggleston, Tesla’s Vice President of 4680 batteries, who wrote that “both electrodes use our dry process.”
Tesla first introduced the dry-electrode concept during its Battery Day presentation in 2020, pitching it as a way to simplify production, reduce factory footprint, lower costs, and improve energy density. While Tesla has been producing 4680 cells for some time, the company had previously relied on more conventional approaches for parts of the process, leading to questions about whether a full dry-electrode process could even be achieved.
4680 packs for Model Y
Tesla also revealed in its Q4 and FY 2025 Update Letter that it has begun producing battery packs for certain Model Y vehicles using its in-house 4680 cells. As per Tesla:
“We have begun to produce battery packs for certain Model Ys with our 4680 cells, unlocking an additional vector of supply to help navigate increasingly complex supply chain challenges caused by trade barriers and tariff risks.”
The timing is notable. With Tesla preparing to wind down Model S and Model X production, the Model Y and Model 3 are expected to account for an even larger share of the company’s vehicle output. Ensuring that the Model Y can be equipped with domestically produced 4680 battery packs gives Tesla greater flexibility to maintain production volumes in the United States, even as global battery supply chains face increasing complexity.

Tesla Giga Texas to feature massive Optimus V4 production line
This suggests that while the first Optimus line will be set up in the Fremont Factory, the real ramp of Optimus’ production will happen in Giga Texas.
Tesla will build Optimus 4 in Giga Texas, and its production line will be massive. This was, at least, as per recent comments by CEO Elon Musk on social media platform X.
Optimus 4 production
In response to a post on X which expressed surprise that Optimus will be produced in California, Musk stated that “Optimus 4 will be built in Texas at much higher volume.” This suggests that while the first Optimus line will be set up in the Fremont Factory, and while the line itself will be capable of producing 1 million humanoid robots per year, the real ramp of Optimus’ production will happen in Giga Texas.
This was not the first time that Elon Musk shared his plans for Optimus’ production at Gigafactory Texas. During the 2025 Annual Shareholder Meeting, he stated that Giga Texas’ Optimus line will produce 10 million units of the humanoid robot per year. He did not, however, state at the time that Giga Texas would produce Optimus V4.
“So we’re going to launch on the fastest production ramp of any product of any large complex manufactured product ever, starting with building a one-million-unit production line in Fremont. And that’s Line one. And then a ten million unit per year production line here,” Musk stated.
How big Optimus could become
During Tesla’s Q4 and FY 2025 earnings call, Musk offered additional context on the potential of Optimus. While he stated that the ramp of Optimus’ production will be deliberate at first, the humanoid robot itself will have the potential to change the world.
“Optimus really will be a general-purpose robot that can learn by observing human behavior. You can demonstrate a task or verbally describe a task or show it a task. Even show it a video, it will be able to do that task. It’s going to be a very capable robot. I think long-term Optimus will have a very significant impact on the US GDP.
“It will actually move the needle on US GDP significantly. In conclusion, there are still many who doubt our ambitions for creating amazing abundance. We are confident it can be done, and we are making the right moves technologically to ensure that it does. Tesla, Inc. has never been a company to shy away from solving the hardest problems,” Musk stated.
