Tesla rumored to use BYD ‘Blade’ battery days after $25k car speculation swirls
Tesla could use Chinese automotive company BYD’s new, ultra-safe “Blade” battery design in some of its vehicles in 2022. The rumors that associate the Blade battery from BYD being paired with Tesla’s successful electric models in China follow a report from just days ago when Tesla was rumored to have already completed a prototype for its $25,000 EV.
Multiple Chinese media sources, including the Associated Press, have reported that people familiar with BYD’s supply chain and plans for the blade battery have indicated that the company will supply Tesla with the pack design as soon as Q2 2022. According to the initial reports, Tesla is already testing its vehicles with the blade batteries, which could have fueled the speculation from several days ago that an affordable $25k car prototype is in the works at Giga Shanghai, Tesla’s Chinese production facility.
The reports stated that Tesla has already entered the “C-sample test phase” with vehicles with the blade battery installed.
BYD’s Blade battery has been developed for several years, but the automotive entity unveiled the design in March 2020. The company began the development to mitigate concerns about battery safety in EVs, a growing concern as the industry began to take off a few years ago.
The design is different than current battery pack designs. In the Blade battery, singular cells are arranged together in an array, then inserted into a battery pack. It eliminates unnecessary space due to arrangement optimization, and the space within the pack is increased by over 50% compared to block batteries, BYD said.

The battery pack underwent extensive testing to ensure safety and efficiency with its design. The Blade pack passed nail penetration tests by not emitting smoke or fire after the pack’s main housing was punctured. Additionally, surface temperatures only reached between 30 and 60 degrees Celsius (86 to 140 Fahrenheit). Traditional pack designs for LFP block batteries did not catch fire, but temperatures reached 200 to 400 degrees Celsius. Additionally, ternary lithium batteries exceeded 500 degrees Celsius and “violently burned,” BYD stated.
Interestingly, several days ago, it was rumored that Tesla might have already completed some prototypes of its $25k sedan that it targets for the Chinese market. The report revealed that Tesla might have already lined up the suppliers for this vehicle. Now that rumors of BYD’s blade battery could be installed in the car to help reach the affordable price point, there is certainly some momentum behind the speculation. Tesla has attempted to develop the $25k car in China for some time, and it will eventually be a global offering from Tesla. However, the company has been ramping production of the Model 3 and Model Y and attempting to keep up with demand in China with those two vehicles.
The $25k Tesla could launch as early as next year. With suppliers beginning to reveal themselves, it is not a long shot to think that Tesla could capture some more of China’s EV market share with a sub-$30,000 vehicle.

Tesla finally got its Nevada Robotaxi Permit but with a few catches hard to miss
Nevada granted Tesla’s robotaxi permit, but capped the fleet at just ten vehicles for now.
Tesla has received its robotaxi permit in Nevada, more than two months after regulators closed the public comment period on the company’s application. News of the approval surfaced Wednesday night when Tesla investor and longtime company watcher Sawyer Merritt posted a copy of the interim order, and the Nevada Transportation Authority’s own carrier registry now lists the permit, AVNC Permit 002 under Docket 26-05015, as active for Tesla Robotaxi, LLC.
Tesla asked Nevada in June for authority to run up to 5,000 vehicles in Clark County within a year, however the permit the NTA issued is initially capping Tesla at ten fully autonomous vehicles and confines them to a defined geofence along the Las Vegas Strip corridor. Any expansion of that operating area, or any increase to the fleet size, requires the NTA’s approval first.

The order also sets rules that look more restrictive than what Tesla runs in Austin. Rides are barred on roads with posted speed limits above 45 miles per hour, pickups are off limits within a quarter mile of Harry Reid International Airport without separate authorization, and every vehicle has to carry visible “Robotaxi” markings while notifying riders before each trip that no one is driving. The order also requires “appropriate human supervision”, language that suggests Nevada isn’t ready to let Tesla offer the rides without a safety monitor that it has run in parts of Austin since January. As with standard protocol with robotaxi services, Tesla must report any accident, system failure, or vehicle that becomes stranded on a Nevada road within five business days.
Tesla is entering a market Nevada already knows well. Zoox, the Amazon owned robotaxi company, has run its own autonomous vehicle permit in the state since last year, building up to roughly 100 vehicles and 350,000 rides along the Strip. That history likely explains why the NTA started Tesla at ten cars rather than the fleet size the company asked for. The agency has a template for scaling a permit up once a company proves out its safety record.

Tesla’s Nevada application first surfaced in June, when the company filed for the permit alongside plans for a maintenance hub in southwest Las Vegas. The company has said it won’t meaningfully scale its robotaxi fleet anywhere until FSD v15 ships, expected in late 2026 or early 2027, which makes the ten vehicle cap less of a constraint today than it might look on paper. For now, Tesla has the legal right to start Nevada rides. Whether it starts before FSD v15 arrives is a separate question the permit doesn’t answer.
Tesla Energy has introduced the Powerwall Lease in conjunction with Tesla Electric, making the service available in Texas. This new option delivers whole-home backup power using two Powerwall units for a net monthly cost of $35 after credits, accompanied by a low fixed electricity rate.
Under the lease terms, customers pay a one-time order fee of $100. The base lease payment for the two Powerwalls is approximately $122 per month during the first year, subject to a 3 percent annual escalator thereafter. Enrollment in a qualifying Tesla Electric Backup plan or Virtual Power Plant plan provides an $87 monthly credit.

This credit lowers the effective cost to roughly $35 per month plus applicable tax.

Installation of the standard system carries no additional charge. The package features Storm Watch for outage protection and allows complete management through a single Tesla application. The system supplies continuous whole-home backup capability.
The Powerwall system enables households to maintain electricity during severe storms that disrupt the utility grid. When outages occur, the batteries automatically provide seamless backup power to the home.

Tesla Storm Watch monitors weather forecasts and ensures the units are fully charged ahead of anticipated severe weather events so that power remains available throughout the disruption, keeping lights, refrigeration, and other essential systems operating without interruption.
Availability is restricted to select Texas locations where retail electric choice exists. Participants must lease exactly two Powerwall units and maintain continuous enrollment with Tesla Electric. Solar panels cannot be included under this particular lease arrangement.
The monthly credit activates automatically once the system is installed, receives permission to operate, and enrollment is confirmed. To retain the credit, customers are required to stay enrolled in Tesla Electric and fulfill all program conditions.
Nonstandard installations that involve electrical upgrades or special permitting may lead to extra expenses and might impact eligibility for the credit, so be sure to check with either your installer or Tesla to ensure you will still qualify.

Elon Musk continues to tease the unveiling event for the Tesla Roadster, a continuing trend that has grown into a bigger game of “When” for fans who have been waiting years for the car to finally enter production.
A video shared on X of the Joe Rogan Experience podcast that Musk appeared on last year, teasing the Roadster unveiling, was shared once again on the social media platform. The poster said the Roadster event will be “unforgettable.”
Musk agreed:
Yes
— Elon Musk (@elonmusk) August 12, 2026
The timing is interesting because just yesterday, Musk said that we will be getting flying cars, and for years, Tesla has hinted that it could develop a SpaceX cold gas thruster package that would help the car float or fly for a short period of time.
It would be reasonable to assume Tesla’s major delays with this unveiling event are likely caused by the company’s need to break the rules and push the envelope on nearly everything. Last July, Lars Moravy, Tesla’s VP of Vehicle Engineering, said:
-
“Roadster is definitely in development. We did talk about it last Sunday night. We are gearing up for a super cool demo. It’s going to be mind blowing. We showed Elon some cool demos last week of the tech we’ve been working on and he got a little excited.”
The latest updates that Tesla has given us are that the Roadster is in design development, and it did have several potential dates for an unveiling event this year, including April. It was then pushed to August.
However, there are no clues as to when Tesla will be ready, and fans are certainly getting frustrated with the delays.
For what it is worth, Franz von Holzhausen told Jay Leno this week that the event would be “very soon.”
We sure hope.
