Tesla streamlined Model 3 battery pack production time by 96%, says Elon Musk
Tesla CEO Elon Musk stated during Wednesday’s Q1 2018 earnings call that the company has managed to reduce the time it takes to produce a Model 3 battery pack by 94%, from 7 hours to under 17 minutes. According to Musk, addressing the over-generalization of the Model 3’s design, as well as the excessive automation in Gigafactory, proved beneficial to the improvement in the manufacturing rate of the car’s battery packs.
“This still remains to be fixed, but in any case, overgeneralizing the design. For example, the current battery pack has a port for front drive units, which we then put a steel blanking plate on. So essentially, we punched a hole in it and put a blanking plate at the hole. And (we had to) do that for all rear drive unit cars, which is kinda crazy.
“It would have added cost, it would have added a manufacturing step, it would have added a failure mode; and four ports was unnecessary… That’s changed. So, the result was we had a rapid improvement in battery pack production, from taking 7 hrs to make a pack 3 weeks ago to under 17 minutes now. We’re able to also achieve a sustained rate of 3,000 vehicles a week, so we’re actually slightly ahead in battery module and pack production than expected.”
With the optimizations to the line in place, Musk revealed that Tesla is now producing 3,000 battery packs per week at the Nevada Gigafactory, with peak hours of production hitting a rate of 5,000 per week.
“In the last 24 hours at the Gigafactory, we managed to keep a sustained rate of over 3,000 packs per week. We actually reached a peak hour, extrapolated outward would be a rate of over 5,000 cars per week… Every hour is as good as its peak. If you can achieve it even once in an hour, then with continued refinement of the system, and improved operational time of the machinery, you can achieve that sustained rate with more refinement.”
Musk reiterated his previous statement about the company automating too much of its production line. According to Musk, Tesla “went too far and automated some pretty silly things,” including an incredibly complex “fluff machine” that ended up making production complicated.
“One of the things we’ve found is that there are some things that are very well suited to manual operations, and there are some things are very well suited to automated operations. The two should not be confused. We did go too far in the automation front, and automated some pretty silly things.
“One example would be, we have these fiberglass mats on top of the battery pack. They’re basically fluff. We tried to automate the placement and bonding of fluff to the top of the battery pack, which was ridiculous. ‘Flufferbot,’ which was really an incredibly difficult machine to make work. Machines are not good at picking up pieces of fluff. Hands are way better at doing that.
“So we had this super-complicated machine, using a vision system to try and put a piece of fluff on a battery pack. The line kept breaking down because Flufferbot would frequently fail to pick up the fluff, or put it in a random location. So, that was one of the silliest things we’ve found.”
The revelations about the improvements in the pace of Model 3 battery pack production are in line with Elon Musk’s recent statements about relying too much on automation. Musk mentioned this in an interview with Gayle King of CBS This Morning, and later in a tweet, where he coyly stated that humans are “underrated.”
Nevertheless, Tesla pointed to strategic automation as key in its Q1 Update Letter. The company, for one, credits the quality improvements in the Model 3 line to the automation that is involved in manufacturing the vehicles. Tesla expects the Model 3 line to be optimized once more after a planned 10-day shutdown in production during the second quarter. With a hiring ramp underway, Tesla is aiming to adjust overtime hours and staffing levels to meet its production goals even further.
Tesla’s first-quarter earnings for 2018 saw the electric car maker posting $3.4 billion in revenue and beating earnings estimates with a loss of $568 million. Losses per share was listed at -$3.35 per share, lower than Wall Street estimates of -$3.58 per share.

Elon Musk explains Tesla’s domestic battery strategy
Elon Musk responded to a new note from an analyst that highlighted Tesla’s battery strategy.

Tesla CEO Elon Musk explained the automaker’s strategy for building batteries from top to bottom in a domestic setting as the company continues to alleviate its reliance on Chinese materials, something other companies are too dependent on.
With the Trump Administration, it is no secret that the prioritization of U.S.-built products, including sourcing most of the materials from American companies, is at the forefront of its strategy.
The goal is to become less dependent on foreign products, which would, in theory, bolster the U.S. economy by creating more jobs and having less reliance on foreign markets, especially China, to manufacture the key parts of things like cars and tech.
In a note from Alexander Potter, an analyst for the firm Piper Sandler, Tesla’s strategy regarding batteries specifically is broken down.
Potter says Tesla is “the only car company that is trying to source batteries, at scale, without relying on China.”
He continues:
“Eventually, Tesla will be making its own cathode active materials, refining its own lithium, building its own anodes, coating its own electrodes, assembling its own cells, and selling its own cars; No other US company can make similar claims.”
Musk, who spent time within the Trump White House through his work with the Department of Government Efficiency (DOGE), said that Tesla is doing the “important” work of localizing supply chains as the risks that come with being too dependent on foreign entities could be detrimental to a company, especially one that utilizes many parts and supplies that are manufactured mostly in China.
It is important, albeit extremely hard work, to localize supply chains to mitigate geopolitical risk
— Elon Musk (@elonmusk) June 3, 2025
Tesla has done a lot of work to source and even manufacture its own batteries within the United States, a project that has been in progress for several years but will pay dividends in the end.
According to a 2023 Nikkei analysis, Tesla’s battery material suppliers were dominated by Chinese companies. At the time, a whopping 39 percent of the company’s cell materials came from Chinese companies.
This number is decreasing as it operates its own in-house cell and material production projects, like its lithium refinery in Texas.
It also wants to utilize battery manufacturers that have plans to build cells in the U.S.
Panasonic, for example, is building a facility in Kansas that will help Tesla utilize domestically-manufactured cells for its cars.

Tesla stock: Morgan Stanley says eVTOL is calling Elon Musk for new chapter
Could Tesla dive into the eVTOL market? Morgan Stanley takes a look.

Tesla shares are up nearly 20 percent in the past month, but that is not stopping the only trillion-dollar automaker from attracting all types of new potential sectors to disrupt, at least from an investor and analyst perspective.
Morgan Stanley’s Adam Jonas is not one to shy away from some ideas that many investors would consider far-fetched. In a recent note, Jonas brought up some interesting discussion regarding Tesla’s potential in the eVTOL industry, and how he believes CEO Elon Musk’s answer was not convincing enough to put it off altogether.
Tesla’s Elon Musk says electric planes would be ‘fun problem to work on’
Musk said that Tesla was “stretched pretty thin” when a question regarding a plane being developed came up. Jonas said:
“In our opinion, that’s a decidedly different type of answer. Is Tesla an aviation/defense-tech company in auto/consumer clothing?”
Musk has been pretty clear about things that Tesla won’t do. Although he has not unequivocally denied aviation equipment, including planes and drones, as he has with things like motorcycles, it does not seem like something that is on Musk’s mind.
Instead, he has focused the vast majority of his time at Tesla on vehicle autonomy, AI, and robotics, things he sees as the future.
Tesla and China, Robotics, Pricing
Morgan Stanley’s note also discussed Tesla’s prowess in its various areas of expertise, how it will keep up with Chinese competitors, as there are several, and the race for affordable EVs in the country.
Tesla is the U.S.’s key to keeping up with China
“In our view, Tesla’s expertise in manufacturing, data collection, robotics/ physical AI, energy, supply chain, and infrastructure are more critical than ever before to put the US on an even footing with China in embodied AI,” Jonas writes.
It is no secret that Tesla is the leader in revolutionizing things. To generalize, the company has truly dipped its finger in all the various pies, but it is also looked at as a leader in tech, which is where Chinese companies truly have an advantage.
Robotics and the ‘Humanoid Olympics’
Jonas mentioned China’s recent showcasing of robots running half marathons and competing in combat sports as “gamification of robotic innovation.”
Tesla could be at the forefront of the effort to launch something similar, as the analyst predicts the U.S. version could be called “Humanoid Ninja Warrior.”
Pricing
Tesla is set to launch affordable models before the end of Q2, leaving this month for the company to release some details.
While the pricing of those models remains in limbo with the $7,500 tax credit likely disappearing at the end of 2024, companies in China have been able to tap incredibly aggressive pricing models. Jonas, for example, brings up the BYD Seagull, which is priced at just about $8,000.
Tesla can tap into an incredibly broader market if it can manage to bring pricing to even below $30,000, which is where many hope the affordable models end up.
During the Q3 2024 Earnings Call, Musk said that $30,000 is where it would be with the tax credit:
“Yeah. It will be like with incentive. So, 30K, which is kind of a key threshold.”

Tesla bull writes cautious note on Robotaxi launch: ‘Keep expectations well contained’
Morgan Stanley’s Adam Jonas is more cautious about Tesla’s upcoming Robotaxi launch.

Tesla analyst Adam Jonas of Morgan Stanley is telling investors to be wary of the Robotaxi details CEO Elon Musk revealed this week, after a report seemed to land on the prospective launch date of the platform in June.
Earlier this week, a report from Bloomberg indicated Tesla had internally landed on a tentative date of June 12 for its Robotaxi launch in Austin. Shortly after, Musk detailed the successful testing Tesla has already performed without anyone in the driver’s seat.
He also indicated Teslas would self-deliver to customers in June.
Analysts are now sending out investor notes on the announcement Musk made, along with the Bloomberg report. Jonas’s note is more cautious than others.
Jonas believes Tesla needs to shed more details before investors and fans of the company get too excited. He believes there is more information that could be released, but until then, he is suggesting investors “keep expectations well contained.”
He wrote:
“As is typical for highly anticipated Tesla events, we would keep expectations well contained for the (reported) June 12th Cybercab launch event in Austin. However, we would look for a continued stream of updates for the performance and growth of the network thereafter (numbers of cars, miles, trips, etc.) in the days and weeks that follow.”
The tone of Jonas’s note contradicts that of Wedbush’s Dan Ives, who believes the “golden age of autonomous” lies in Tesla’s hands. He seems to believe Tesla will come through on its June 12 launch.
Tesla set for ‘golden age of autonomous’ as Robotaxi nears, ‘dark chapter’ ends: Wedbush
Morgan Stanley’s note is slightly more
Jonas is obviously still bullish, but is much more tentative to move forward with an attitude that communicates skepticism about what Tesla has revealed.
Jonas and Morgan Stanley have a $410 price target on Tesla shares with a ‘Buy’ rating. Tesla stock is trading at around $358 at 12:15 p.m. on the East Coast.
