BYD is responding to a report that it’s testing solid-state EV batteries in its Tesla Model 3-rivalling Seal. The rumors claimed Seal could achieve a total driving range of nearly 1,200 miles (1,875 km). Here’s what BYD is saying.
BYD begins testing solid-state EV batteries in the Seal
It has been over a decade since BYD first began researching and developing the promising new EV battery technology.
Last year, the company reached a milestone by testing its first solid-state battery cells with capacities of 20 Ah and 60 Ah.
We knew BYD was planning to launch its first vehicles powered by the new batteries in 2027 after Sun Huajun, the CTO of BYD’s battery business, BYD Lithium Battery Co, confirmed the timeline earlier this year.

A few days ago, a local report claimed that at the 2025 China All-Solid-State Battery Innovation and Development Summit, Sun stated that BYD had installed solid-state batteries in its popular Seal EV and had begun testing them on roads.
BYD shut down the rumors, saying in a statement on June 23 (via CLS), “Currently it is unknown, and the first model and parameters are not officially reported.”
The report also noted Sun’s comments that BYD plans to begin installing solid-state batteries in its production vehicles around 2027.

Between 2027 and 2029, production will be limited during the first two years. However, in 2030, BYD plans to begin mass production. BYD has previously said that by the end of the decade, it expects “liquid and solid to be the same price.” In other words, solid-state batteries will be about the same cost as current liquid lithium-ion batteries.

The rumors claimed BYD’s solid-state batteries have an energy density of 400 Wh/kg, or nearly twice that of current lithium-ion batteries.
The report also stated that BYD’s solid-state EV batteries set a record by gaining a 1,500 km (932 miles) range in just 12 minutes of charging.

According to the report, the test charged the battery to only 80%, claiming the total EV range could reach upwards of 1,875 km (1,165 miles). Keep in mind that this is the CLTC range. On the EPA scale, it would be closer to 1,300 km (808 miles), which is still way more than enough.
BYD’s Seal currently starts at just 175,800 yuan in China, or about $25,000. However, it looks like we’ll have to wait to see which EV BYD will launch first with solid-state batteries.
Electrek’s Take
BYD is already dominating the global EV market. It just surpassed Tesla in Europe and the UK in monthly registrations for the first time, and this could be just the start.
With several new batteries and plenty of other EV technologies, including ultra-fast chargers, smart driving features, and advanced new platforms, BYD is laying the groundwork for more growth over the next few years.
Not only that, BYD is already known for its low-cost cars, like the Seagull (Dolphin Surf in Europe), priced under $10,000 in China. The new tech is expected to unlock longer driving range, faster charging, and lower costs.
Even after it begins producing solid-state batteries, however, BYD plans to continue offering LFP batteries as a lower-cost option.
BYD will compete with CATL, Mercedes-Benz, Volkswagen, Stellantis, Nissan, and several others that are also aiming to launch their first EVs with solid-state batteries around 2027 or 2028. Nissan’s director of product planning in Europe, Christop Ambland, confirmed the company’s timeline this week with Auto Express, saying, “We will be ready for SSB (solid-state batteries) in 2028.”
Time-of-use electricity plans are hardly a new concept, but what makes Octopus Energy’s new time-of-use plan, OctopusFlex, great is that it’s ridiculously simple.
It rewards its customers in Lubbock, Texas, for using power between 10 pm and 6 am with cheaper rates, when the grid is quieter and cleaner. That means big savings for choosing to run your dishwasher or washer and dryer at night or charging your EV while you sleep.
And if customers use EV charger apps and smart thermostats, OctopusFlex automatically shifts electricity use to off-peak hours, which makes a real difference in accessing lower rates and saving money.
“This is about more than off-peak discounts,” said Nick Chaset, CEO of Octopus Energy US. “We’re giving customers the power to save money while actively supporting a cleaner, more balanced grid.”

Built around customer feedback, OctopusFlex is designed for total transparency. Customers can see exactly how and when they’re using electricity, what it’s costing them, and no connected devices are required. All they have to do is remember that electricity is cheaper from 10 pm to 6am.
“We’re thrilled to launch OctopusFlex, a plan our customers asked for and helped name,” said Katie Rosario, marketing manager. “With OctopusFlex, customers can shift energy use on their terms to save money.”
And in the summer, when solar power is strong and demand shifts, OctopusFlex customers could see low rates not just overnight, but all day long. (This program is designed for folks who don’t have solar and battery storage.)
“Time-of-use is one of the easiest ways to cut energy bills and reward flexibility,” said Daniel Kirwin, product manager. “We couldn’t be more excited to bring this to Texas.”
By nudging demand to off-peak hours, OctopusFlex helps reduce the strain on Texas’ grid during scorching summer afternoons, cuts the risk of blackouts, and makes room for more renewable energy.
Want to make the most of it? Pre-cool your home in the early morning, run big appliances overnight, charge your EV after 10 pm, and use smart plugs or timers to set and forget.
OctopusFlex is now live in Lubbock, Texas, where Octopus Energy became a retail provider in early 2024. Octopus Energy launched in 2016 and entered the US market in 2020. The company is part of Octopus Group, a global certified BCorp operating in 18 countries.

Are you sick of hearing BYD’s name yet? You may want to get used to it. Another one of its EV models crossed a major milestone on Monday as BYD’s global push heats up.
BYD Atto 3 EV hits 1 million cumulative sales milestone
BYD announced on Weibo that its cumulative global sales of the Yuan Up electric SUV surpassed the 1 million mark on Monday.
The Yuan Up is sold in China and rebranded under the name Atto 3 in global markets. It’s the third vehicle in BYD’s Dynasty series to achieve this feat, following the BYD Song (sold globally under the name Seal U) and the Qin sedan.
BYD first launched the electric SUV in China in February 2022, meaning it took just over three years and four months to sell one million units.

In China, the Yuan Up starts at just 115,800 yuan ($16,100), but overseas, it typically costs more. For example, the Atto 3 starts at around 38,000 euros ($44,000) in Europe. In Thailand, it was launched at around 1,099,900 baht ($33,600), but BYD has since slashed the prices to around 899,900 baht ($27,500).
After launching the electric SUV in Hyundai and Kia’s home market of Korea earlier this year, the Atto 3 secured over 1,000 preorders in under a week.
Measuring 4,455 mm in length, 1,875 mm in width, and 1,615 mm in height, the Atto 3 is a small SUV, about the size of the Nissan Qashqai.

In China, the Yuan Up is available with two LFP battery options: 49.9 kWh and 60.5 kWh, providing a CLTC range of 430 km (267 miles) and 510 km (317 miles), respectively. The Atto 3 is rated with a WLTP range of 345 km (214 miles) and 420 km (261 miles).
The Yuan Up (Atto 3) is the latest BYD EV to reach the milestone. Last week, it was BYD’s top-selling electric car, the Seagull.
BYD’s Seagull EV starts at under $10,000 (69,800 yuan) in China and is sold globally under the name Dolphin Mini. In Europe, where it was launched earlier this month, it’s sold as the Dolphin Surf, with starting prices at € 19,990 ($23,100).

The world seems awfully tinderbox-y these days, what with a heat dome descending over the US, the Strait of Hormuz getting locked down, and gas prices set to climb on rising oil prices. As such, it might be a good time to buy that slick new EV you’ve had your eye on. If that sounds like you, you’re in luck! There are a bunch of great plug-in cars you can buy with 0% financing in June, 2025!
As I was putting this list together, I realized there were plenty of ways for me to present this information. “Best EVs ..?” Too opinion based. “Cheapest EVs ..?” Too much research. “Biggest discount deal ..?” Too individualized. In the end, I went with alphabetical order, by make. And, as for which deals are new this month? You’re just gonna have to check the list. Enjoy!
Acura ZDX
2025 Acura ZDX; via Acura.
A solidly-built EV with GM levels of parts support and Honda levels of fit, finish, and quality control plusApple CarPlay? That’s the Acura ZDX, and (through June 30th) you can get yours with 0% financing for up to 72 months, making the ZDX one the best sporty crossover values in the business.
Chevy Brightdrop ZEVO
Chevrolet BrightDrop ZEVO; via GM.
GM Authority is reporting that the $25,500 discount rolled out to Chevy Brightdrop dealers nationwide has been extended through June 30th on both the Zevo 400 and 600 models, and that the massive Brightdrop price drop is stackable with up to $3,000 in Costco member savings plus 0% interest financing.

If you’re looking for a new truck for your business or even a unique #vanlife ride with zero emissions, modern tech, and a nationwide dealer network, GM makes that $130 Executive membership seem like a no-brainer.
Every electric Chevrolet
Silverado EV, Equinox EV, and Blazer EV at a Tesla Supercharger; via GM.
Chevrolet is offering 0% financing for up to 60 months on all three of its remaining 2024 model year Ultium-based EVs – and they’re all winners. The Silverado can be spec’ed up to a 10,500 lb. GVWR, making it capable enough to tow whatever horse, boat, or RV you put behind it.
Dodge dealers are hoping that at least a few muscle car enthusiasts with extra cash will find their way to a Dodge store and ask for the meanest, loudest, tire-shreddingest thing on the lot without caring too much about what’s under the hood. For them, Dodge has the new electric Charger, and Dodge will help get the deal done on its latest retro-tastic ride with 0% interest financing for up to 72 months!
Ford Mustang Mach-E, F-150 Lightning
F-150 Lightning with home charger; via Ford.
This month, you can get a killer deal on a new Ford Mustang Mach-E, with 0% interest financing for up to 72 months on the sporty plug-in pony car.
Another legacy brand with a solid Powerwall option, the big Ultium-based EVs from GM’s commercial truck brand are seriously impressive machines, with shockingly quick acceleration and on-road handling that seems to defy the laws of physics once you understand that these are, essentially, medium-duty trucks. This month, GMC is doing its best to move out its existing inventory, so if you’re a fan of heavy metal you’ll definitely want to stop by your local GMC dealer and give the Hummer EV a test drive.
Hyundai IONIQ 6
Hyundai IONIQ 6; via Hyundai.
From some angles, the Porsche influences in the Hyundai IONIQ 6′ design are obvious – but not so much so that it seems like a copy of anything. It’s aerodynamically efficient, comfortable, quick, offers up to 361 miles of range, can charge just about anywhere, and now through June 30th, it’s available with 0% financing for up to 48 months.
Jeep Wagoneer S
Electric Jeep Wagoneer S; via Stellantis.
With some dealers advertising massive $25,000 discounts, the Jeep Wagoneer S is a confusingly named EV diamond in the rough. This high-riding crossover rides on a lifted version of the same Stellantis platform as the Dodge Charger, and seems more than ready to deliver solid range and on-road performance.
With those killer deals and 0% interest for up to 72 months through June 30th, the Wagoneer S might just be the best Jeep deal you’re going to find this month!
Lexus RZ
2024 Lexus RZ 450e Luxury; via Lexus.
Starting at $55,175, the Lexus RZ promises up to 266 miles of EPA-rated range from a 72.8 kWh battery back in the “base” RZ300e (and 224 from the top-shelf RZ450e, shown above). With up to 308 hp and over 195 lb-ft of instant, all-electric torque, the RZ promises to be one Lexus’ zippier rides in any trim.
US News is reporting that remaining 2024 and ’25 Lexus RZ models qualify for 0% financing for up to 72 months in some regions.
Nissan Ariya

I’ve already said that the Nissan Ariya didn’t get a fair shake. If you click that link, you’ll read about a car that offers solid driving dynamics, innovative interior design, and all the practicality that makes five-passenger crossovers the must-haves they’ve become for most families. With up to 289 miles of EPA-rated range, Tesla Supercharger access, and 0% interest from Nissan for up to 72 months, Nissan dealers should have no trouble finding homes for these.
Tesla Model 3

Say what you will about Elon Musk, we wouldn’t be here talking about EVs at all if it wasn’t for his marketing brilliance, bravado, and sheer force of will. Beyond that, Tesla simply offers as superior ownership experience through total software integration, unfettered access to the Supercharger network, and the best EV route-planning software this side of Chargeway.
If you can stomach being associated with Elon (or have an inside line on some spare Honda badges), you can get a new Model 3 for 0% interest or 0.99% with $0 down if you apply the $7,500 Federal tax incentive at the point of purchase.
With an updated bZ waiting in the wings, the current bZ4X EV might be the best deal in Toyota’s current lineup with big discounts on remaining 2024 and 2025 model year bZ4X crossovers happening all month long.
VW ID.4
VW ID4.
One of the most popular legacy EVs, the ID.4 offers Volkswagen build quality and a Chat-GPT enabled interface. Still, with a relatively affordable base price, lickety-quick charging, up to 291 miles of EPA-rated range, and a 5-star safety rating, and 0% interest financing for 72 months, the ID.4 offers a value proposition that’s tough to beat.
