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 has adjusted the functionality of a crucial climate feature as Winter weather has started to arrive throughout some parts of the United States. The new feature was highly requested by owners.
Tesla has a Cabin Overheat Protection feature that helps keep the temperature regulated if it reaches a certain threshold. Inversely, it can be used in cold weather as well, which will automatically warm the cabin if it sinks to a temperature that is too low for the owner’s comfort.
This is a great way to keep the cabin either warmed up just enough or cooled down just enough so that it never gets too hot or too cold. Extreme temperatures could damage certain parts of the vehicle or damage personal belongings that are kept inside the car.
Overheat protection is a great thing to have in hot climates like Arizona or Texas, especially with the Premium trims of the Model 3 and Model Y, which feature a glass roof.
Many owners appreciate the feature, but they argue that using it at home will utilize too much energy, especially during extreme temperatures. For a while, many Tesla fans have requested an option to disable this feature when the car is parked at home, which the company recently added, according to Not a Tesla App.
The feature is part of Software Version 2025.44.3, and the release notes state:
“You can now choose Exclude Home when Cabin Overheat Protection or No A/C is enabled.”
Tesla has been great at listening to what owners want with new features, and this is one that will reserve some charge and prevent unnecessary utilization of available power, especially as the car is parked at home. If owners want to condition the cabin or get the car ready for operation with a comfortable interior, they can utilize the Tesla app to adjust the climate.
Tesla CEO Elon Musk revealed today on the social media platform X that legacy automakers, such as Ford, General Motors, and Stellantis, do not want to license the company’s Full Self-Driving suite, at least not without a long list of their own terms.
“I’ve tried to warn them and even offered to license Tesla FSD, but they don’t want it! Crazy,” Musk said on X. “When legacy auto does occasionally reach out, they tepidly discuss implementing FSD for a tiny program in 5 years with unworkable requirements for Tesla, so pointless.”

Musk made the remark in response to a note we wrote about earlier today from Melius Research, in which analyst Rob Wertheimer said, “Our point is not that Tesla is at risk, it’s that everybody else is,” in terms of autonomy and self-driving development.
Wertheimer believes there are hundreds of billions of dollars in value headed toward Tesla’s way because of its prowess with FSD.
A few years ago, Musk first remarked that Tesla was in early talks with one legacy automaker regarding licensing Full Self-Driving for its vehicles. Tesla never confirmed which company it was, but given Musk’s ongoing talks with Ford CEO Jim Farley at the time, it seemed the Detroit-based automaker was the likely suspect.

Ford has been perhaps the most aggressive legacy automaker in terms of its EV efforts, but it recently scaled back its electric offensive due to profitability issues and weak demand. It simply was not making enough vehicles, nor selling the volume needed to turn a profit.
Musk truly believes that many of the companies that turn their backs on FSD now will suffer in the future, especially considering the increased chance it could be a parallel to what has happened with EV efforts for many of these companies.
Unfortunately, they got started too late and are now playing catch-up with Tesla, XPeng, BYD, and the other dominating forces in EVs across the globe.
Tesla is backtracking on a strange adjustment it made to its in-car Navigation feature after numerous complaints from owners convinced the company to make a change.
Tesla’s in-car Navigation is catered to its vehicles, as it routes Supercharging stops and preps your vehicle for charging with preconditioning. It is also very intuitive, and features other things like weather radar and a detailed map outlining points of interest.
However, a recent change to the Navigation by Tesla did not go unnoticed, and owners were really upset about it.
For trips that required multiple Supercharger stops, Tesla decided to implement a naming change, which did not show the city or state of each charging stop. Instead, it just showed the business where the Supercharger was located, giving many owners an unwelcome surprise.
However, Tesla’s Director of Supercharging, Max de Zegher, admitted the update was a “big mistake on our end,” and made a change that rolled out within 24 hours:
The naming change should have happened at once, instead of in 2 sequential steps. That was a big miss on our end. We do listen to the community and we do course-correct fast. The accelerated fix rolled out last night. The Tesla App is updated and most in-car touchscreens should…

The lack of a name for the city where a Supercharging stop would be made caused some confusion for owners in the short term. Some drivers argued that it was more difficult to make stops at some familiar locations that were special to them. Others were not too keen on not knowing where they were going to be along their trip.
Tesla was quick to scramble to resolve this issue, and it did a great job of rolling it out in an expedited manner, as de Zegher said that most in-car touch screens would notice the fix within one day of the change being rolled out.
Additionally, there will be even more improvements in December, as Tesla plans to show the common name/amenity below the site name as well, which will give people a better idea of what to expect when they arrive at a Supercharger.
