Tesla’s potential as a future battery supplier for other automakers is being paved by the ongoing struggles of the company’s rivals today. This idea is becoming more and more feasible as more and more veteran automakers experience battery-related challenges in their respective electric car programs.
Building electric cars is no easy task. As evidenced by the issues plaguing the rollout of the mass-market Volkswagen ID.3, making good electric vehicles is not just a matter of stuffing an electric motor and batteries in an existing platform for an internal combustion car. Making EVs, especially good, high-performing ones like the Tesla Model 3, requires mastery of a different set of skills, such as software management and battery optimizations.
The latter is where a vast divide exists between Tesla and legacy automakers today. Tesla utilizes its own proprietary battery tech for its vehicles. The 2170 cells for its Model 3 sedan are even being produced at Giga Nevada, a massive factory that is poised to become one of the largest in the world by footprint once it’s completed. Veteran automakers, on the other hand, rely on suppliers such as LG Chem to supply their EVs’ batteries.
LG Chem supplies cells to several automakers, including Audi and Jaguar, whose e-tron and I-PACE both utilize the company’s batteries. Rivian, which uses 2170 cells for the R1T pickup and the R1S SUV, source their cells from the South Korean firm as well. More recently, even startup Lucid Motors, which is reportedly on the cusp of releasing its first vehicle, the Air, also announced that it would be sourcing cells from LG Chem. This is great for LG Chem, as it validates the quality and capabilities of its batteries, but it also does not bode well for all the companies looking to acquire adequate battery supply for their electric cars.
As it is, LG Chem appears to be having difficulties meeting the demand for its vehicles already. Shortages of cells from the battery manufacturer have reportedly become the cause for the recent halts in the Audi e-tron and the Jaguar I-PACE’s production. And this is just with premium-priced, mid-volume SUVs. When high-volume vehicles enter the market, such as the Volkswagen ID.3 (which also gets some of its cells from LG Chem), the South Korean firm will likely find it even more challenging to supply batteries to all its clients.
This supply issue could become a serious challenge to the electric car revolution. With this in mind, and with even more electric cars coming in the next few years, a need for another battery supplier emerges. This is where Tesla comes in. Tesla has been expanding its business to not just focus on building electric cars, as evidenced by the company’s energy and battery storage initiatives. Considering Tesla’s experience in building EVs, as well as the industry-leading quality of its batteries, the company may very well be poised to become one of the leading suppliers of cells for other electric car makers.
Interestingly enough, CEO Elon Musk has mentioned the possibility of Tesla serving as a supplier of batteries and powertrains to other automakers in the past. This was explained by Musk himself during the Q3 2019 earnings call. “It would be consistent with the mission of Tesla to help other car companies with electric vehicles on the battery and powertrain front, possibly on other fronts. So it’s something we’re open to. We’re definitely open to supplying batteries and powertrains and perhaps other things to other car companies,” he said.
Fiat-Chrysler CEO Steve Manley also suggested the idea during a Q&A session. Speaking about the company’s electric vehicle strategy, Manley mentioned that Fiat-Chrysler would likely be purchasing key electric car components from the Silicon Valley-based company. “It would be wrong of me to say no,” Manley said, adding that batteries and drivetrains will likely be among the parts that FCA will be purchasing from Tesla. The CEO also expressed the possibility of FCA acquiring a “skateboard” platform from Tesla, which it would use for its own vehicles.
Tesla is at a point where its lead in the electric car space is undeniable. The company is also at a point where its manufacturing systems are more refined than before. Tesla may thus be reaching a stage where it is large and robust enough to support other automakers that are also adopting electric cars. As veteran carmakers transition into EVs, those who can secure battery supply from Tesla will likely be the ones that will survive what could very well be a painful and costly move towards sustainability.

Tesla Model 3 and Model Y can now do what only Cybertruck could
Tesla Model 3 and Model Y can power your home with Powerwall 3 during outages.
Tesla has turned its two top sellers into backup batteries for the house.
Tesla Energy announced on Tuesday that Powershare Home Backup is now available for new Model 3 and Model Y vehicles paired with a Powerwall 3, saying the car can “extend your home backup by over 2 days.” Minutes later, Tesla’s main account quoted the post with a broader pitch: “With Powerwall 3, every Tesla can now serve as your home’s backup battery.”
Until this week, the Cybertruck was the only Tesla that could send power back into a home, and that capability only began working alongside Powerwall 3 last month, after years of ambitious targets.
Tesla’s updated Powershare page says every Model 3 and Model Y ordered in the U.S. or Puerto Rico on or after October 1, 2026 can use the feature. Some, but not all, earlier cars also qualify. Owners can check on the touchscreen under Software, then Additional Vehicle Information, where a capable car shows “Powershare Support: Enabled.” As Electrek reported, bidirectional power on the two cars runs through an inverter Tesla calls PCS2 Lite, and the company has not said when that part entered production on each trim.
The home side is simpler. A house that already has a Powerwall 3 and either a Wall Connector 3 or Universal Wall Connector needs no additional equipment, and Tesla says compatibility is enabled through a software update. When the grid drops, the Powerwall and the car work together, with up to 11.52 kW of continuous power available. Tesla’s “over two days” estimate assumes a home using 30 kWh per day and a car starting at a 90 percent charge. Standard trims are rated for up to two days, while the Cybertruck adds more than three.
There are limits. Powerwall 2 and Powerwall+ support is listed as “coming soon.” Model S and Model X are not included, and Grid Support, the program that lets Cybertruck owners in Texas send power back to the grid during demand spikes for bill credits, is not available for Model 3 or Model Y.
The rollout also lines up with something Elon Musk said more than three years ago. At Tesla’s March 2023 Investor Day, Musk said, “I don’t think very many people are going to want to use bidirectional charging, unless you have a Powerwall.” Tesla has now shipped the feature for its volume cars with exactly that requirement attached.
The Powerwall pairing was the hard part on Cybertruck. Tesla told owners in December 2025 that Powershare with Powerwall had been pushed to mid 2026, and lead engineer Wes Morrill explained that two devices capable of forming a home’s grid have to negotiate which one leads during an outage, across multiple generations of hardware. With that work done for the truck, Tesla was able to extend it to the Model 3 and Model Y within a month.
Ford and GM have offered home backup from their EVs for several years, but both require a separate inverter and backup hardware. Tesla’s version leans on equipment many Powerwall 3 owners already have on the wall. Powershare for the two cars also ships as part of software update 2026.38.3, the same release that began delivering Halloween Mode on Tuesday.
Tesla is now starting to ship a “Halloween Mode” that is filled with some creepy and fun features; the company says, “This spooky update turns your Tesla into a haunted house on wheels.”
The update is just the latest in a series of updates that Tesla typically ships out in a seasonal fashion. The Spring and Summer Updates provided some fun novelty items while also packing some cool features that are actually useful for the ownership experience.
This one seems to be more fun-forward, and there are not any updates to the Full Self-Driving suite or overall operation of the vehicle. Instead, these novelty features are geared toward getting you in the mood for the Fall and Halloween.

SpaceX reveals how its 1 Million AI satellite network will work and prevent space collisions
SpaceX reveals plans for one million Starmind AI satellites and calls out operators hiding maneuvers.
SpaceX has put the largest satellite count it has ever published into writing, and it says that plan only works if every other operator in orbit starts sharing what it knows.
In a new Space Safety page highlighted Tuesday morning by Sawyer Merritt on X, SpaceX said it “plans to operate up to 100,000 Starlink satellites and up to 1 million Starmind AI satellites to meet the growing demand for broadband and supercompute.” Starlink has a little over 11,000 satellites in orbit today, so the target alone implies roughly a ninefold expansion of the broadband network.
Starmind is SpaceX’s orbital AI compute constellation. Elon Musk confirmed the Starmind name in June after an xAI trademark filing surfaced, and in August SpaceX said it was working with Nvidia on the compute payload. The FCC accepted the filing for up to one million satellites back in February.
FCC accepts SpaceX filing for 1 million orbital data center plan
SpaceX also released a new render of what a full Starmind constellation could look like. Alongside it, SpaceX VP Michael Nicolls explained why the satellites will not operate on their own. “We need to operate clusters of satellites in tight formation to get enough coherent compute to run AI models efficiently,” Nicolls said. “A cluster will be 10-ish satellites connected with 10 terabits or so of bandwidth between them, and interconnected to the broader constellation.”
That is the most specific detail SpaceX has given on how Starmind will be built. Instead of a million independent servers, the network would work as tightly packed groups of about 10 satellites acting as one compute unit, with Starlink’s laser links carrying results back to Earth.
There is a bright and exciting future for humanity ahead – and space is fundamental to that future.
To achieve this, space safety must be done right. We encourage every operator to not only share ephemeris data proactively the same way Starlink already does, but to also adopt the high standards of space safety that SpaceX and Starlink use every day → https://t.co/QizAkQZvEm

Packing satellites that close together, at that scale, makes collision avoidance the central problem, and most of the Space Safety page is aimed at other operators. SpaceX said Starlink encountered collision risks with about 650 unique maneuvering third party satellites in 2026, and only about half of them shared data. Over six months, Starlink recorded roughly 164,000 more collision risks where the closest approach came within four hours of an unannounced maneuver.
Some operators keep maneuver plans private over proprietary concerns, while others cannot get government permission to share them. SpaceX called those policies “counterproductive,” saying they “largely only serve to create preventable collision risk between satellites.” Starlink is also offering a free ephemeris sharing and screening platform that returns risk results within a minute, backed by its Stargaze network of 30,000 optical sensors.
The push comes as the Starmind application draws opposition from astronomers and environmental groups. In a September filing with the FCC, SpaceX said each Starmind satellite could weigh up to 4,000 kg, nearly seven times the mass of a Starlink V2 Mini. Musk has brushed off crowding concerns before, telling viewers in June that “space is enormous” and that SpaceX already knows how to run very large constellations safely.
SpaceX’s Starmind page says its Gigasat factory in Bastrop, Texas, is designed to produce AI satellites at scale, with deployment of thousands of units starting as soon as late 2027.
