Tesla Supercharger V3 details: 250 kW, no charge splitting, twice as fast
Tesla launched its newest V3 Supercharger at an official unveiling event in Fremont, California, Wednesday night.
As we first reported, V3 Superchargers will be able to charge twice as fast the current generation Supercharger with a maximum power output of 250 kW or 1,000 miles per hour. Additionally, Tesla owners using V3 Superchargers will no longer need to split power with neighboring vehicles, thereby substantially increasing the charge rate and reducing the overall amount of charging time by nearly half.
Supercharger V3 details first surfaced Wednesday evening in Release Notes for a new over-the-air firmware update that went out to Model 3 owners, first captured by Erik @teslainventory on Twitter.
Tesla began to roll out the over-the-air firmware update to a small group of Model 3 owners that were invited to attend the official Supercharger V3 unveiling. Attendees are members of Tesla’s “Early Access Program” who will be one of the first to use Tesla’s next-generation Supercharger.
The firmware update went out ahead of the event to prepare these vehicles to accept the higher power output from Tesla’s newest ultra-fast chargers.
“Your Model 3 is now able to charge at V3 Superchargers at up to 250 kW peak rates. Supercharger stations with V3 hardware are designed to enable 
Of note is the final sentence in the section for “Supercharger Improvements”, which indicates that the firmware update will allow a vehicle to condition its batteries before arriving at a V3 Supercharger station. “Also, when you navigate to a Supercharger, your call will condition its battery during the drive, so it can charge faster,” reads the release note.
Preconditioning a battery isn’t something new for Tesla vehicles, especially for P100D owners looking to ‘Bring it on!‘ with Ludicrous Mode. Being able to optimize the temperature of the battery cells allows them to be in a state that can operate at higher current and thereby charge at the higher 250 kW power.
At the moment, our understanding is that only Model 3, which utilizes a newer generation 2170 cell compared to the older 18650 form factor cell found in Model S and Model X, will be able to V3 Supercharge at full potential.
Be sure to check back as we will update the story with full details and specifications for Tesla Supercharger V3.
Update: Tesla published details for V3 Supercharging in a company blog post (included below). A video of the fast charging speed can be seen in their video.
Introducing V3 Supercharging
Tesla has more than 12,000 Superchargers across North America, Europe, and Asia and our network continues to grow daily: more than 99% of the U.S. population is covered by the network, and we anticipate similar coverage in Europe by the end of 2019. Recently, we passed 90% population coverage in China and are growing that number quickly. However, in order to drive continued electric vehicle adoption and further accelerate the world’s transition to sustainable energy, charging needs to be even faster, and the number of vehicles able to charge at a location in a day needs to be significantly higher. Today, we’re unveiling V3 Supercharging, the next step in the growth of Tesla’s Supercharger network. V3, which is born from our experience building the world’s largest grid-connected batteries, enables our vehicles to charge faster than any other electric vehicle on the market today.
Faster Charging, No More Power Sharing
V3 is a completely new architecture for Supercharging. A new 1MW power cabinet with a similar design to our utility-scale products supports peak rates of up to 250kW per car. At this rate, a Model 3 Long Range operating at peak efficiency can recover up to 75 miles of charge in 5 minutes and charge at rates of up to 1,000 miles per hour. Combined with other improvements we’re announcing today, V3 Supercharging will ultimately cut the amount of time customers spend charging by an average of 50%, as modeled on our fleet data.
Supercharger stations with V3’s new power electronics are designed to enable any owner to charge at the full power their battery can take – no more splitting power with a vehicle in the stall next to you. With these significant technical improvements, we anticipate the typical charging time at a V3 Supercharger will drop to around 15 minutes.
On-Route Battery Warmup
New Supercharging infrastructure isn’t the only way we are improving our customers’ charging experience. Beginning this week, Tesla is rolling out a new feature called On-Route Battery Warmup. Now, whenever you navigate to a Supercharger station, your vehicle will intelligently heat the battery to ensure you arrive at the optimal temperature to charge, reducing average charge times for owners by 25%.
This combination of higher peak power with V3, dedicated vehicle power allocation across Supercharger sites, and On-Route Battery Warmup 
With Model 3 now shipping globally in high volumes and Model Y on the way, V3 Supercharging enables us to deliver the fastest production charging experience at an unprecedented scale compared to other electric vehicle manufacturers. By increasing the number of vehicles we’re able to charge at each Supercharger in a day, the investment we’re making in our network will go significantly further with every V3 station deployed. Paired with other savings, these efficiencies will translate to an increased pace of investment for Superchargers moving forward, with a continued focus on getting to 100% ownership coverage across all regions we operate. With thousands of new Superchargers coming online in 2019, the launch of V3, and other changes we’re making to improve throughput, the Supercharger network will be able to serve more than 2x more vehicles per day at the end of 2019 compared with today – easily keeping pace with our 2019 fleet growth.
Beginning today, we’re opening the first public beta site in the Bay Area, which will incrementally be made available to owners in Tesla’s Early Access Program. We’re launching V3 Supercharging for Model 3, our highest volume vehicle, and we’ll continue to expand access as we review and assess the results of millions of charging events. We will increase Model S and X charging speeds via software updates in the coming months. V3 Supercharging will roll out to the wider fleet in an over the air firmware update to all owners in Q2 as more V3 Superchargers come online. Our first non-beta V3 Supercharger site will break ground next month, with North American sites ramping in Q2 and Q3 before coming to Europe and Asia-Pacific in Q4.

Tesla Cybercab display highlights interior wizardry in the small two-seater
Photos and videos of the production Cybercab were shared in posts on social media platform X.
The Tesla Cybercab is currently on display at the U.S. Department of Transportation in Washington, D.C., and observations of the production vehicle are highlighting some of its notable design details.
Photos and videos of the production Cybercab were shared in posts on social media platform X.
Observers of the Cybercab display unit noted that the two-seat Robotaxi provides unusually generous legroom for a vehicle of its size. Based on the vehicle’s video, the compact two-seater appears to offer more legroom than Tesla’s larger vehicles such as the Model Y, Model X, and Cybertruck.
The Cybercab’s layout allows Tesla to dedicate nearly the entire cabin to passengers. The vehicle is designed without a steering wheel or pedals, which helps maximize interior space.
Footage from the display also highlights the Cybercab’s large center screen, which is positioned prominently in front of the passenger bench. The display appears intended to provide entertainment and ride information while the vehicle operates autonomously.
Images of the vehicle also show an additional camera integrated into the Cybercab’s C-pillar. The extra camera appears to expand the vehicle’s field of view, which would be useful as Tesla works toward fully unsupervised Full Self-Driving.
Tesla engineers have previously explained that the Cybercab was designed to be highly efficient both in manufacturing and in operation. Cybercab Lead Engineer Eric E. stated in 2024 that the Robotaxi would be built with roughly half the number of parts used in a Model 3 sedan.
“Two seats unlocks a lot of opportunity aerodynamically. It also means we cut the part count of Cybercab down by a substantial margin. We’re gonna be delivering a car that has roughly half the parts of Model 3 today,” the Tesla engineer said.
The Tesla engineer also noted that the Cybercab’s cargo area can accommodate multiple golf bags, two carry-on suitcases, and two full-size checked bags. The trunk can also fit certain bicycles and a foldable wheelchair depending on size, which is quite impressive for a small car like the Cybercab.

Elon Musk’s xAI wins permit for power plant supporting AI data centers
The development was reported by CNBC, citing confirmation from the Mississippi Department of Environmental Quality (MDEQ).
Mississippi regulators have approved a permit allowing Elon Musk’s artificial intelligence company xAI to construct a natural gas power plant in Southaven. The facility is expected to support the company’s expanding AI infrastructure tied to its Colossus data center operations near Memphis.
The development was reported by CNBC, citing confirmation from the Mississippi Department of Environmental Quality (MDEQ).
According to the report, regulators “voted to approve the permit” of xAI subsidiary MZX Tech LLC to construct a power plant featuring 41 natural gas-burning turbines “after careful consideration of all public comments and community concerns.”
The Mississippi Department of Environmental Quality stated that the permit followed a regulatory review process that included public comments and community input. Jaricus Whitlock, air division chief for the MDEQ, stated that the project met all applicable environmental standards.
“The proposed PSD permit in front of the board today not only meets all state and federal permitting regulations, but goes above and beyond what is required by law. MDEQ and the EPA agree that not a single person around our facilities will be exposed to unhealthy levels of air pollution,” Whitlock stated.
The planned facility will help provide electricity for xAI’s AI computing infrastructure in the Memphis region.
The Southaven project forms part of xAI’s efforts to scale computing capacity for its artificial intelligence systems.
The company currently operates two major data centers in Memphis, known as Colossus 1 and Colossus 2, which provide computing power for xAI’s Grok AI models. xAI is also planning to build another large data center in Southaven called Macrohardrr, which would be located in a warehouse previously used by GXO Logistics.
Large-scale AI training requires substantial computing power and electricity, prompting technology companies to develop dedicated energy infrastructure for their data centers.
SpaceX President Gwynne Shotwell previously stated that xAI plans to develop 1.2 gigawatts of power capacity for its Memphis-area AI supercomputer site as part of the federal government’s Ratepayer Protection Pledge. The commitment was announced during an event with United States President Donald Trump.
“As part of today’s commitment, we will take extensive additional steps to continue to reduce the costs of electricity for our neighbors. xAI will therefore commit to develop 1.2 GW of power as our supercomputer’s primary power source. That will be for every additional data center as well. We will expand what is already the largest global Megapack power installation in the world,” Shotwell said.
“The installation will provide enough backup power to power the city of Memphis, and more than sufficient energy to power the town of Southaven, Mississippi where the data center resides. We will build new substations and invest in electrical infrastructure to provide stability to the area’s grid.”

Tesla China teases Optimus robot’s human-looking next-gen hands
The image was shared by Tesla AI’s account on Weibo and later reposted by Tesla community members on X.
A new teaser shared by Tesla’s China team appears to show a pair of unusually human-like hands for Optimus.
The image was shared by Tesla AI’s account on Weibo and later reposted by Tesla community members on X.
As could be seen in the teaser image, the new version of Optimus’ hands features proportions and finger structures that look strikingly similar to those of a human hand. Their appearance suggests that they might have dexterity approaching that of a human hand.
If the image reflects a new generation of Optimus’ hands, it could indicate Tesla is continuing to refine one of the most critical components of its humanoid robot.
Hands are widely viewed as one of the most difficult engineering challenges in robotics. For Optimus to perform complex real-world work, from manufacturing tasks to household activities, its hands would need to be the best in the industry.
Elon Musk has repeatedly described Optimus as Tesla’s most important long-term product. In posts on social media platform X, Musk has stated that Optimus could eventually become the first real-world Von Neumann machine.
In theory, a Von Neumann machine is a self-replicating system capable of building copies of itself using available materials. The concept was originally proposed by mathematician John von Neumann in the mid-20th century.
“Optimus will be the first Von Neumann machine, capable of building civilization by itself on any viable planet,” Musk wrote in a post on X.
If Optimus is expected to carry out complex work autonomously in the future, high levels of dexterity will likely be essential. This makes the development of advanced robotic hands a key step towards Musk’s long-term expectations for the product.
