Polestar will trial StoreDot’s ~350kW DC-capable battery on Polestar 5 prototype
Polestar will trial StoreDot’s “extreme fast charging” technology on its upcoming Polestar 5, enabling the addition of 100 miles of range in 5 minutes of charging.
We’re at Polestar Day in Santa Monica today, where the company is showcasing its future plans to media, investors and owners. For more news from the day, check out our Polestar Day News Hub.
Polestar is an investor in StoreDot, and today at Polestar Day, it has announced that it will demo StoreDot’s 100in5 battery technology in its Polestar 5, formerly known as the Precept concept, a sleek 4-door GT electric car.
StoreDot, an Israel-based company, has demonstrated battery and charging technology that it dubs “100in5,” due to its ability to add 100 miles of range in 5 minutes of charging. It also calls this “XFC” technology, short for “Extreme Fast Charging.”
It’s a clever marketing effort, aiming to make it easier for the public to understand just how fast EVs can charge when using the highest-speed chargers in the best conditions.
But for us in the EV world, it might better to translate that into the kW numbers we all know and love. Polestar and StoreDot don’t have an actual kW number, but we can come up with an estimate based on average consumption numbers.
Doing some rough math on average EV consumption (~300Wh/mi), 100 miles would mean about 30kWh of energy, which means a charge rate of around 360kW if you can get that amount of juice in 5 minutes. Round it down to 350kW since we’ve seen that number before and we’ll call it a day.
Currently, Polestar vehicles can mostly charge in the 200-250kW range, which is pretty quick. Most EVs coming out these days can charge somewhere in the 150-180kW range (with some slower ones out there, like our much-loved Chevy Bolt still at 50kW), and the better performers are in the 200s or even into the 300s.
But 350kW on the car end of things only works if the network also supports speeds that fast. Currently, Tesla’s superchargers cap out at 250kW, but the upcoming V4 superchargers will be capable of 350kW, and Electrify America has “hyper-fast” 350kW chargers in many locations.
Even at current charge rates of 250kW and below, the best electric cars available today are already fantastic for roadtrips – assuming they’re paired with a well-functioning fast charging network. On that front, Polestar did recently commit to joining the NACS standard, opening up access to Tesla’s Supercharger network.
350kW would be about the fastest-charging car available if it was out today, but Polestar 5 will only trial this technology for now, and it won’t be in production in a few years.
Just a few days ago, Polestar announced that it will use Korean battery supplier SK On for production-spec Polestar 5 batteries when the vehicle starts production in 2025, and we don’t know what charge rates that car will be capable of. It plans to bring the StoreDot XFC batteries into production-spec Polestar 5s in 2027.
At that point, though, StoreDot says its future “100in3” solid state batteries will almost be available (that translates to around 600kW, for reference). Those are supposed to hit production in 2028 – so it’s perhaps a little strange that Polestar would start using the 100in5 models in 2027, 3 years after they’re supposed to become available, and 1 year before the better model shows up.
That said, solid state batteries have been “just around the corner” for longer than I’ve been following EVs (and that’s a long time), so we wouldn’t be surprised to see that timeline get pushed back a little.

Rivian founder and CEO RJ Scaringe has posted another interesting facet into the design of the American automaker’s upcoming R2 BEVs. As you’ll see below, the Rivian R2’s body harness has been significantly reduced in size, weight, and connections to enable lower assembly costs and an overall more environmentally friendly build.
If you’re not following RJ Scaringe on social media, you’re missing out. While some CEOs shy away from social media (aside from the guy who bought Twitter to create his own toxic echo chamber), Rivian’s founder has used such platforms to share interesting company progress.
In the past month, much of Scaringe’s content has pertained to the design and development of Rivian’s upcoming R2 model, and we have been all about it. In the past two weeks, RJ has shared a peek at the company’s new Maximus drive unit and photos of the R2 validation builds on a pilot line at the automaker’s facility in Normal, Illinois.
Last week, Scaringe took to Instagram and X once again to share a better look at the inner workings of the Maximus drive unit. The unit was designed to be more compact and efficiently built to help reduce the cost-per-unit production for the Rivian R2 assembly process.
Today, RJ posted more evidence of how much more optimized components of the R2 design will be.
The body harness design of the R2 is significantly simpler
RJ posted the comparison image above to Instagram this afternoon, detailing just how much more streamlined the R2’s body harness design will be compared to the Gen 2 R1 BEVs. The Rivian CEO elaborated with the following caption:
The R2 harness improves massively over the R1 Gen 2 harness. Building on the backbone of our network architecture and zonal ECUs, we focused on ease of install in the plant and overall simplification through integrated design — less wires, less clips and far fewer splices!
Simplified indeed, this reimagined body harness cuts serious weight and connectors. The front section of the body harness, in particular, truly encapsulates just how streamlined the R2’s design components are becoming. A body harness pic may not be the most exciting news to the general public, but as a BEV enthusiast on the Rivian beat, it’s amazing to see, and we hope RJ will continue to post updates like this going forward.

JPMorgan Chase CEO Jamie Dimon delivers a speech during the Global Markets Conference, ahead of the Choose France summit, in Paris, on May 15, 2025.

JPMorgan Chase is finally allowing clients to buy bitcoin. But CEO Jamie Dimon is still a skeptic.
“We are going to allow you to buy it,” Dimon said at the bank’s annual investor day on Monday. “We’re not going to custody it. We’re going to put it in statements for clients.”
The decision marks a notable step for the largest U.S. bank, particularly due to Dimon’s history of criticizing the digital currency and the crypto market broadly, and is the latest sign of bitcoin’s entry into mainstream investing. Since August, Morgan Stanley has allowed its financial advisors to pitch some spot bitcoin exchange-traded funds to qualifying clients.
Dimon made it clear that his personal view of bitcoin remains unchanged, highlighting issues like money laundering and the lack of clarity surrounding ownership, along with “the sex trafficking, the terrorism.”
“I don’t think you should smoke, but I defend your right to smoke,” Dimon said. “I defend your right to buy bitcoin.”
A JPMorgan spokesperson declined to elaborate on the bank’s specific plans for bitcoin access. Until now, the company has limited its crypto exposure primarily to futures-based products, not direct ownership of bitcoin.
When crypto valuations were soaring in 2021, Dimon dismissed bitcoin as “worthless.” He told lawmakers during a Senate hearing in late 2023 that he’s “always been deeply opposed to crypto, bitcoin, etc.,” and that, “The only true use case for it is criminals, drug traffickers … money laundering, tax avoidance.” He said at the hearing that, “If I was the government, I’d close it down.”
At the 2024 World Economic Forum in Davos, Dimon said, “Bitcoin does nothing. I call it the pet rock.” He added that, “This is the last time I’m talking about the with CNBC, so help me God.”
Morgan Stanley CEO Ted Pick told CNBC at this year’s event in Davos that the investment bank is exploring ways to deepen its involvement in cryptocurrency markets, navigating the regulatory landscape under the pro-crypto administration of President Donald Trump.
Since President Trump took office in January, the Federal Deposit Insurance Corporation and Office of the Comptroller of the Currency have rescinded their anti-crypto guidance. While banks can now custody crypto, thanks to the repeal of an accounting rule called SAB 121, they still face restrictions on working directly with crypto firms without explicit approval from the Federal Reserve.
Genesis is preparing to introduce its new flagship EV, the GV90. The brand’s largest, most luxurious electric SUV already looks stunning. The Genesis GV90 was spotted with less camo ahead of its debut, giving us a sneak peek of the “ultra-luxe” EV.
Genesis GV90 EV sheds camo during testing
We got our first look at the flagship Genesis model last March with the Neolun concept, a preview of its first full-size electric SUV.
Inspired by Korea’s iconic moon-shaped porcelain jars, the Neolun Concept is “the epitome of timeless design and sophisticated craftsmanship,” according to the luxury brand’s creative officer, Luc Donckerwolke. Genesis calls it “the ultra-luxe vision of luxury SUVs.”
The GV90 is not just a stunning-looking vehicle. It will also serve as a tech beacon for Genesis with Hyundai Motor’s most advanced software and tech, including a massive 24.6″ infotainment.
This is all great, but the feature that caught the most attention was GV90’s coach doors. Ahead of its debut, we’ve seen the GV90 out in the wild for testing a few times, including with coach doors.
Genesis claims B-pillarless coach doors are now feasible in production vehicles, hinting they will be offered on the production model. However, the feature is expected to only be offered on higher-priced trims.
Most recently, the Genesis GV90 EV was caught by the folks at SH Proshots testing at the Nürburgring with notably less camo. The new images (via TheKoreanCarBlog) give us our best look at the flagship electric SUV, and it already looks like a stunner.
A few design elements, like the two-line LED headlamps, are shown, while you can see a good outline of the vehicle’s profile.
Like the concept, the GV90 appears to retain its minimalistic design shown in the Neolun concept. With an extended wheelbase, you can clearly see the size difference compared to its other EVs, like the GV60 or Electrified GV70.
The full-size electric SUV is expected to be the first Hyundai Motor model to ride on the new eM platform, which is set to replace the current E-GMP underpinning current Kia, Hyundai, and Genesis EVs.
Although production was slated to begin later this year at Hyundai’s Ulsan plant in South Korea, a recent report from The Korea Economic Daily claims Hyundai’s new development plan now calls for it to begin in June 2026.
Prices and final specs will be revealed closer to launch, but the GV90 is expected to start at around 100 million won ($80,000) in Korea. More premium trims could cost over 200 million won ($160,000).
