Tesla Supercharger V3 details: 250 kW, no charge splitting, twice as fast

Published

on

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 any owner to charge at the full power their battery can take – no more splitting power with another vehicle connected to your cabinet. This combination of higher peak power and dedicated vehicle power allocation across the site enables you to charge in half the time.”

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 enables customers to charge in half the time and Tesla to serve more than twice the number of customers per hour. Additionally, we are also unlocking 145kW charge rates for our 12,000+ V2 Superchargers over the coming weeks.

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.

SpaceX Board has set a Mars bonus for Elon Musk

SpaceX has given Elon Musk the goal to put one million people on Mars.

Rendering of a colonized Mars by way of SpaceX

SpaceX’s board approved a compensation plan for Elon Musk that ties his pay directly to colonizing Mars and building data centers in outer space. The details surfaced this week after Reuters reviewed SpaceX’s confidential registration statement filed with the Securities and Exchange Commission, making it one of the first concrete looks inside the company’s financials ahead of a public offering.

The pay package will reportedly award Musk 200 million super-voting restricted shares if the company hits a market valuation milestone, with the most ambitious targets going further. To unlock the full award, SpaceX would need to reach a $7.5 trillion valuation and help establish a permanent human settlement on Mars with at least one million residents. Additional incentives are tied to developing space-based computing infrastructure capable of delivering at least 100 terawatts of processing power.

SpaceX wins its first MARS contract but it comes with a catch

Long before SpaceX filed anything with the SEC, Elon Musk had already spent years framing Mars colonization as an insurance policy against human extinction. The philosophy traces back to at least 2001, when Musk first began researching Mars missions independently, before SpaceX even existed. By 2002 he had founded the company with Mars as the stated long-term goal.

In a 2017 presentation at the International Astronautical Congress, Musk outlined the specific vision that still underpins SpaceX’s architecture today. He described a self-sustaining city on Mars requiring roughly one million people to become viable, the same number now written into his compensation package.

SpaceX’s Starship, still in active development, was designed from the ground up to support the eventual colonization of Mars. Musk has stated publicly that getting the cost per ton to Mars below $100,000 is necessary to make mass migration economically feasible. Everything from Starship’s payload capacity to its full reusability targets flows from that single constraint. One can say that Musk’s latest compensation package has put a formal valuation on Mars for the first time.

SpaceX is targeting an IPO around June 28, Musk’s birthday, at a valuation of approximately $1.75 trillion. Between the Mars rover contract, the Golden Dome software group, Space Force satellite launches, and now a pay structure built around interplanetary colonization, SpaceX has become the single most consequential contractor in American space and defense. The IPO will put a public price tag on all of it for the first time.

Tesla’s biggest rivals fights charging wait times with a modern approach

Published

Tesla V4 Supercharger installation ramping in Europe

Earlier this week, we wrote a story on how Tesla is launching a new Supercharging Queue system to mitigate problems between drivers when there is a wait to charge.

Rather than potentially having people end up in a physical conflict, Tesla’s approach is to determine who is next to charge based on geographic data.

Tesla launches solution to end Supercharger fights once and for all

But some companies, notably Tesla’s biggest rival in China, BYD, are taking a different approach, focusing on charging speeds rather than how they will manage delays.

BYD’s approach, especially with its tests of ultra-fast “Flash Charging” technology, is to eliminate the length of a charging session. At the heart of this strategy is BYD’s second-generation Blade Battery paired with 1,500-kW Flash Chargers.

Unveiled earlier this year, the system charges compatible vehicles from 10 percent to 70 percent state of charge in just five minutes and from 10 percent to 97 percent in nine minutes.

Real-world demonstrations on models like the Yangwang U7 and Denza Z9 GT have shown the tech delivering roughly 250 miles (400 kilometers) of range in just five minutes. This would essentially match or beat the time it takes to fill a gas tank.

Sometimes, gas pumps get congested, and there are lines. You rarely see conflicts at pumps because filling up a tank rarely takes more than five minutes.

Tesla’s fastest Supercharger build currently is the v4, which can deliver up to 325 kW for Cybertruck and 250 kW for other models, but there are “true” sites that are capable of up to 500 kW. This enables speeds of up to 1,000 miles per hour, or 1,400 miles for 350 kW-capable vehicles.

The breakthrough stems from BYD’s vertically integrated ecosystem: a new 1,000-volt architecture, 10C charging rates, and proprietary silicon-carbide chips that minimize internal resistance while protecting battery health.

The company plans to install 20,000 Flash Charging stations across China by the end of 2026, with thousands already operational and global expansion eyed for Europe and beyond later this year.

Early rollout targets popular models, including upgrades to high-volume sellers like the Seal and Sealion series, bringing five-minute charging to mainstream prices around 100,000 yuan (about $14,000).

This approach contrasts sharply with Tesla’s software solution. Tesla’s Virtual Queue uses geofencing and the app to assign turns at crowded sites, addressing driver disputes and idle time. It’s a clever fix for today’s network realities.

Yet, BYD’s philosophy is simpler: make charging so fast that waits barely exist. A five-minute stop becomes as convenient as a gas-station visit, reducing station dwell time, easing grid strain, and lowering range anxiety for long trips.

For consumers, the difference is potentially tangible. They’ll spend more time driving and less time parked. It is just another way Tesla and BYD are pushing one another to improve the overall experience of EV ownership.

Tesla wins big as NHTSA drops three-year, 120k unit probe against Model Y

In all, 120,089 Model Ys were impacted, but in two cases, drivers reported the complete detachment of the steering wheel from the steering column while the vehicle was in motion. NHTSA’s initial review revealed that the vehicles had been delivered without the critical retaining bolt that secures the steering wheel to the splined steering column.

A probe into over 120,000 2023 Tesla Model Y units has been closed by the National Highway Traffic Safety Administration (NHTSA). The probe ends without the agency requiring any action from Tesla.

The probe, designated PE23-003, opened in March 2023 and stemmed from just two consumer complaints involving low-mileage Model Y SUVs.

In all, 120,089 Model Ys were impacted, but in two cases, drivers reported the complete detachment of the steering wheel from the steering column while the vehicle was in motion. NHTSA’s initial review revealed that the vehicles had been delivered without the critical retaining bolt that secures the steering wheel to the splined steering column.

Factory records showed each car had undergone an “end-of-line” repair at Tesla’s facility, during which the steering wheel was removed and reinstalled. The bolt was apparently omitted after the repair, leaving only a friction fit between the wheel and column to hold it in place temporarily.

According to NHTSA documents, this friction fit maintained the connection during initial low-mileage driving until forces during normal operation caused the wheel to detach. Both vehicles that were impacted were repaired under warranty with no injuries reported, and no additional incidents surfaced during the agency’s three-year review.

Tesla Model Y steering wheel detachments prompt NHTSA probe

After analyzing manufacturing processes, complaint data, and field reports, NHTSA concluded the issue was isolated to those two post-repair vehicles rather than indicative of a systemic defect in Tesla’s production or quality control.

The closure means the agency has determined no recall or further enforcement is warranted for this specific missing-bolt condition.

This outcome marks the second NHTSA investigation into Tesla closed without action this month, as a recent probe into the company’s “Actually Smart Summon” feature was also resolved in April.

Tesla Full Self-Driving feature probe closed by NHTSA

The two resolutions provide some relief for Tesla amid the continuous and somewhat unfair regulatory scrutiny of its vehicles, including open inquiries into driver assistance systems.

Importantly, the closed probe does not involve or affect Tesla’s separate May 2023 voluntary recall of certain 2022-2023 Model Y vehicles. That recall addressed a different issue—steering-wheel fasteners that were installed but not torqued to specification—prompted by a service technician’s observation of a loose wheel during unrelated repairs.

Tesla identified a small number of related warranty claims and proactively addressed the matter without NHTSA mandate.

The Model Y remains one of the world’s best-selling vehicles, and Tesla continues to refine its lineup, including the recent “Juniper” refresh. While federal oversight of the electric vehicle pioneer remains intense, this decision underscores that isolated manufacturing anomalies do not always translate into broader safety defects requiring recalls.
