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 just unlocked sales to 50,000+ government agencies
It marks a significant step in expanding Tesla’s presence in the public sector, where procurement processes have traditionally slowed electric vehicle adoption.
Tesla just unlocked sales to over 50,000 government agencies by entering a new agreement with Sourcewell, a purchasing cooperative.
Tesla entered a new master purchasing agreement with Sourcewell, the largest government purchasing cooperative in the U.S. This will enable streamlined sales of its EVs to more than 50,000 U.S. public entities. Tesla entered Designated Contract 0813525-TES, and the agreement covers Model 3, Model Y, and Cybertruck, and potentially other vehicles the company could release.
It marks a significant step in expanding Tesla’s presence in the public sector, where procurement processes have traditionally slowed electric vehicle adoption.
The deal allows eligible agencies, including cities, school districts, state governments, and higher-education institutions, to purchase Tesla vehicles directly through Sourcewell without conducting their own lengthy competitive bidding or request-for-proposal (RFP) processes.
Pricing is pre-negotiated and capped, providing transparency and predictability. Agencies simply register for a Sourcewell account online or by phone and place orders under the existing contract. This cooperative model aggregates demand across thousands of members, reducing administrative costs and time while ensuring compliance with public procurement rules.
For Tesla, the agreement removes major barriers to government fleet sales. Public-sector procurement cycles often stretch 12 to 18 months due to bidding requirements and committee reviews.
Tesla buyers in the U.S. military can get $1,000 off Cybertruck purchases
By securing the master contract, Tesla gains immediate, simplified access to a massive customer base that previously faced friction in adopting EVs. The company highlighted in its announcement that the partnership will help these 50,000-plus agencies “save thousands of $$$ in operating costs for their vehicle fleet over time” through lower maintenance, energy efficiency, and the elimination of tailpipe emissions.
The initial four-year term runs through November 13, 2029, with options for up to three one-year extensions, offering long-term stability for both parties.
Sourcewell’s role is central to execution. As a cooperative purchasing organization, it negotiates and manages vendor contracts on behalf of its members, then makes them available nationwide. Participating entities contact Tesla’s dedicated fleet team or Sourcewell representatives to complete purchases, bypassing redundant paperwork.
This structure accelerates fleet electrification while maintaining fiscal accountability—agencies receive pre-vetted pricing and terms without reinventing the wheel for each vehicle order.
The partnership positions Tesla to capture a larger share of the public fleet market, where total cost of ownership often favors electric vehicles once procurement hurdles are removed.
For government buyers, it translates to faster deployment of sustainable fleets, reduced long-term expenses, and alignment with environmental mandates. As more agencies transition, the contract could contribute to broader EV infrastructure growth and taxpayer savings across the country.

How much of SpaceX will Elon Musk own after IPO will surprise you
SpaceX’s IPO filing confirms Musk will maintain his voting power to make key decisions for the company.
Elon Musk will retain dominant voting control of SpaceX after it goes public, according to the company’s IPO prospectus that was filed with the SEC. The filing reveals a dual-class equity structure giving Class B shareholders 10 votes each, concentrating power with Musk and a handful of other insiders, while Class A shares sold to public investors carry one vote.
Musk holds approximately 42% of SpaceX’s equity and controls roughly 79% of its votes through super-voting shares. He will simultaneously serve as CEO, CTO, and chairman of the nine-member board after the listing. Beyond that, the filing includes provisions that may limit shareholders’ influence over board elections and legal actions, forcing disputes into arbitration and restricting where they can be brought.
The case for Musk holding this level of control is grounded in SpaceX’s actual history. The company’s most important bets, from reusable rockets to a global satellite internet constellation, were decisions that ran against conventional aerospace thinking and would likely have faced resistance from a board accountable to investor gains. Fully reusable rockets were considered economically irrational by established industry players for years. Starlink, which now generates over $4 billion in annual operating profit, was widely dismissed as financially unviable when it was proposed. The argument for concentrated founder control seems straightforward, and the decisions that built SpaceX into what it is today required someone willing to ignore consensus and absorb years of losses.
SpaceX files confidentially for IPO that will rewrite the record books
For context, Musk’s position is significantly more dominant than Zuckerberg’s at Meta. The comparison with Tesla is also worth noting. When Tesla did its IPO in 2010, it did not issue dual-class shares. Musk has only recently pushed for enhanced voting protection, proposing at least 25% control at Tesla in 2024 after selling shares to fund his Twitter acquisition left him with around 13%.
SpaceX has clearly learned from that experience and structured the IPO differently by planning to allocate up to 30% of shares to retail investors, roughly three times the typical norm for a large offering. The roadshow is expected to begin the week of June 8, with a Nasdaq listing rumored to be a $1.75 trillion valuation and a $75 billion raise.

Tesla bolsters App with new safety, insurance, and storage features
The Tesla Smartphone App is one of the biggest and best features and advantages owners have. Everything from moving the vehicle with Summon, to getting Navigation sent to the car, to preconditioning the cabin can be done with the Tesla App.
Tesla is bolstering its smartphone App with a series of new features to streamline operations for owners. The new additions include fixes to safety, its in-house insurance offering, and storage management for Dashcam clips.
The Tesla Smartphone App is one of the biggest and best features and advantages owners have. Everything from moving the vehicle with Summon, to getting Navigation sent to the car, to preconditioning the cabin can be done with the Tesla App.
But in classic Tesla fashion, the company is aiming to improve the offerings of the app, and it is doing so with a handful of new features. They were first discovered by Tesla App Updates.
Tesla Insurance – Safety Score 3.0
This is truly part of the Spring 2026 Update, but Tesla has now given more transparency on how FSD has saved people money on their premiums.
Tesla intertwines FSD with in-house Insurance for attractive incentive
Additionally, Tesla is now automatically awarding a Safety Score of 100 for every mile traveled on Full Self-Driving (Supervised).
Update Tracking
Updates traditionally appear on the App or on the Center Touchscreen in the car. There is nothing better than seeing that Green Arrow at the top of the screen, or opening your app and seeing that there is a Software Update available.
Now, there will be no need to manually check the app and initiate the download. Tesla is enabling a new feature that will automatically download updates for you.
Storage Management
Your USB drive can now be remotely formatted, and old Dashcam clips can be deleted straight from the phone. When you record a lot of things using the Dashcam feature, that storage fills up pretty quickly.
Now, manually deleting the Dashcam videos is easier than ever.
Trailer Light Test
This is perhaps the coolest and most crucial addition to the Tesla App, as those who tow and haul will now be able to trigger a diagnostic light sequence from the app while standing behind your trailer to ensure the brake lights work.
Verifying your trailer lights are connected properly and operating normally and as intended is normally a massive hassle.
Now, a new trigger will be available to initiate a diagnostic light sequence directly from your phone.
