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.

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.
Elon Musk has acknowledged that early discussions with Taiwan Semiconductor Manufacturing Company (TSMC) could bring the company into his ambitious Terafab semiconductor project, signaling a possible partnership with the world’s leading contract chipmaker.
Musk confirmed that early talks are underway, but as of right now, they are “just discussions.” There is no confirmation of a deal nor dismissal of the possibility of one, leaving open the prospect of one of the largest advanced-chip collaborations under discussion in the U.S.
@wholemars Just discussions, but something may come of it
— Elon Musk (@elonmusk) October 3, 2026
The report that speculated on potential discussions between Terafab and TSMC comes from Tim Culpan, who outlined a few ways the collaboration could operate. One is TSMC using the project as an “anchor customer” for future facilities in Texas, potentially contributing process expertise, operational know-how, or capacity while Terafab provides capital, long-term purchase commitments, or both.
Tesla and SpaceX jointly developed the Terafab project, with Intel already participating on the tech side. Elon Musk announced the project in March, and it intends to produce more than one terawatt of AI compute capacity annually once fully built.
Company statements place the first phase at approximately $16.8 billion in cost, with later filings pointing to a total that could reach well into the tens of billions across multiple stages.
Intel joined the effort in April 2026 and is expected to supply its 14A manufacturing process for the full-scale plant.
Musk has said existing suppliers, including Samsung and TSMC, remain important for near-term needs; Tesla already has production arrangements with Samsung for AI5 and AI6 chips, but that future demand from Optimus robots, Cybercab vehicles, and planned space-based data centers will eventually exceed what the global industry can currently deliver.
Terafab is positioned as the long-term answer to that projected shortfall, and Tesla did something similar during COVID to avoid a chip shortage. This is just a much larger-scale solution.
If the partnership were to materialize, it would add TSMC’s industry-leading strategies to a project that already combines Tesla’s and SpaceX’s capital and offtake with Intel’s process technology. For now, the only public confirmation is Musk’s brief acknowledgement that conversations are occurring.
Tesla’s early strategy for charging units operating within its Robotaxi fleet reveals that the company surely has not lost any of that scrappy DNA that took it from an unlikely success story to the most valuable carmaker in the world.
An observer at a Tesla Supercharger in Austin spotted ten total Robotaxi vehicles arrive: one Cybercab and nine Model Y units. A Tesla employee was waiting at the lot and allowed each unit to park itself; every car that arrived had nobody in it.

The Tesla employee would walk around and plug each car in, adjusting the parking if needed:
So look at what I found. This is how Tesla charges unsupervised robotaxis at a public supercharger. Here is a driverless Cybercab showing up with no one in it. There are 9 other Model Ys that showed up too. A Tesla employee is walking around and plugging each of them in. She also moves the cars if they are not positioned well enough to charge. I love this process. One person charges multiple robotaxis at once

It’s a very interesting strategy, but extremely understandable at this early point in the Robotaxi program. It’s only been out for about 15 months, and Cybercab just entered the fleet in early September.
On top of that, Tesla is still working tirelessly on its wireless charging apparatus, and a new patent was just published regarding that product last week.
However, this is just another example of how Tesla still has plenty of that scrappy DNA leftover from the “production hell” days, when CEO Elon Musk slept on the floor of the factory, employees were working crazy hours, Tesla was building Sprung Structures to build cars in, and the company was tiptoeing on the brink of bankruptcy.
@Teslarati Sheer magnitude of the entire production system is hard to appreciate. Almost every element of production is >75% automated. Only wire harnesses & general assembly, which are <10% of production costs, are primarily manual.

For now, Tesla is utilizing a simple system for recharging its ride-hailing vehicles, and that is a Tesla employee doing it manually until another solution presents itself. Sure, it’s not the most high-tech thing, and it certainly is not what people might have expected at this point in time, but it works, and it’s keeping the entire suite running.
Tesla is expanding its Robotaxi service hours by pushing the time back by one hour, keeping the ride-hailing service operational until 11 p.m., one hour later than previously.
CEO Elon Musk confirmed the change and offered a specific reason the expansion has been gradual: the system still needs to reliably avoid small pets that are difficult to see after dark, as they commonly blend into the color of the road, especially when they’re grey.
The latest adjustment restores only a fraction of the operating window the service once held. When paid Robotaxi rides began in Austin on June 22, 2025, vehicles ran from 6 a.m. to midnight.
In September 2025, Tesla lengthened the day to a 2 a.m. close, producing a 20-hour window that stayed in place for most of the following year. By early August of this year, the cutoff had already been pulled back; an August 26 update formalized hours of 6 a.m. to 10 p.m. across Austin and several other markets.
The October move to 11 p.m. therefore leaves the Austin day one hour shorter than the original launch schedule and three hours shorter than the 2025 peak.
Musk addressed the constraint directly after the announcement. “The main thing we’re trying to solve is making sure that we don’t run over pets when they’re hard to see at night,” he wrote. “Literally trying to avoid grey kittens on grey tarmac in the dark.”
Robotaxi operating hours moved from 10pm to 11pm.

The example points to a low-contrast perception problem in which a small animal can blend into the road surface under limited lighting.
Tesla’s vehicles rely on cameras and neural-network processing rather than lidar; Musk has previously argued that advanced vision software can extract useful information even in low light by analyzing photon counts, but the pet-detection case remains the stated limiter in later hours.
The modest schedule change arrives alongside faster growth in the purpose-built Cybercab fleet. Texas registration data tracked by observers showed the Austin Cybercab count rising sharply in recent weeks, reaching 169 vehicles after more than 100 were added in a short span.
Tesla has indicated that a broader shift toward 24-hour operation is tied to the upcoming FSD v15 software release expected this month on Robotaxi vehicles. Until that capability is validated for the edge cases Musk described, the company continues to add service time incrementally rather than jumping straight to overnight coverage.
The one-hour extension gives Austin riders a later option for evening trips while the underlying detection work continues.
