Tesla to unlock Powerwall 2 with more power in upcoming software update
The Tesla Powerwall 2 battery is about to get significantly more impressive, with CEO Elon Musk recently noting that the residential energy storage unit is poised to receive a free software update in the near future. This update, which could roll out sometime next month, would allow some Powerwall batteries to have a power increase of over 50%.
Musk’s remarks about the upcoming Powerwall 2 update came as a follow-up to his previous statements on Wednesday night, when he announced that Tesla’s residential energy products will now be sold exclusively as a bundle. In his follow-up, the CEO stated that the Powerwall 2’s peak and steady power capability is actually better than advertised, and now that the company has enough data, it’s time to uncork the residential battery storage unit’s potential.
Powerwall 2 peak & steady power capability is better than advertised.
Now that we have lots of operational data, Tesla can unlock higher capabilities for free via software update next month.
Depending on production date, power increase power may be >50% at 30C ambient temp.

“Powerwall 2 peak & steady power capability is better than advertised. Now that we have lots of operational data, Tesla can unlock higher capabilities for free via software update next month. Depending on production date, power increase power may be >50% at 30C ambient temp,” Musk wrote.
An over-the-air software update for a home battery unit definitely seems like a strategy that’s right up Tesla’s alley, though it should be noted that a power increase of 50% is a very notable improvement. With such an update in place, homeowners with the battery units would be able to wire up and maintain service on 50% more circuits, allowing users to keep more appliances active during a power outage.
Granted, this may result in the Powerwall 2 batteries getting discharged faster in some cases, but the advantages definitely seem to outweigh the disadvantages in this scenario. The only damper in Elon Musk’s update was his mention of the power increase only being rolled out to batteries that were produced after a specific date. This means that some Powerwall 2 owners may miss out on the free 50% power increase.
The Powerwall 2 may be one of Tesla’s most humble products, but the home battery unit is making waves in its own segment over the years. Last year alone, data from EnergySage in its eleventh semiannual Solar Marketplace Intel Report determined that the Powerwall is dominating the US’ residential battery market. This is partly due to Tesla’s battery technology, which allows the Powerwall to compete aggressively as the country’s least expensive storage option on a per-kWh stored basis.

Elon Musk confirms cryptic X post was related to SpaceX, not TSLA stock
Musk shared his update in a post on social media platform X.

Elon Musk has confirmed that a cryptic post he shared earlier this month was related to his private sale enterprise, SpaceX, not electric vehicle maker Tesla.
Musk shared his update in a post on social media platform X.
Musk’s cryptic post
Earlier this month, the CEO posted the cryptic words “You’ll Thank Me Later” on X. The post quickly gained attention on social media, as Tesla watchers and Elon Musk fans speculated on what the words could mean. With the announcement that Musk has purchased $1 billion of TSLA stock in the open market, some speculated that the cryptic post was a teaser of sorts to shareholders.
Musk’s massive TSLA purchase was the biggest in history, and it also stood as a notable vote of confidence for the company as it attempts to enter a new era led by robots, AI, and autonomous driving. This was likely one of the reasons why Tesla stock saw a notable rise on Monday’s trading. In another post, however, Musk confirmed that his cryptic post was not in any way related to his stock purchase.
All SpaceX
Considering that all the words in Musk’s post started with an uppercase letter, some space fans immediately speculated that the CEO was teasing something related to SpaceX. The company’s three drone ships, Just Read the Instructions (JRTI), Of Course I Still Love You (OCISLY), and A Shortfall of Gravitas (ASOG), after all, follow similar naming styles.
This was one of the reasons why some TSLA shareholders noted on X that Musk’s post was likely SpaceX-related. In response to one of these comments, Musk stated that these speculations are “Correct.”
The only question now is what exactly Musk was referring to in his post. Perhaps the CEO really was hinting at the name of the drone ship that will be tasked to retrieve Starship in the middle of the ocean.

Tesla Model Y leads as weekly registrations in China hit Q3 high
Out of Tesla China’s 15,350 registrations, the Model Y once again accounted for the majority.

Tesla recorded 15,350 insurance registrations in China during the week of September 8–14, marking a 7.3% increase compared to the prior week. The figure also represents the highest weekly result so far in the third quarter of 2025.
Model Y still leads demand
Out of the 15,350 registrations, the Model Y once again accounted for the majority. Data shows 9,460 registrations for the standard Model Y, complemented by 1,030 units of the newly launched extended wheelbase, six-seat Model Y L. Tesla also logged 4,860 Model 3 sedans for the week as well, as noted in a CNEV Post report.
The Model Y L, which debuted in late August, registered a modest uptick from the 900 registrations it saw the week before. Volumes remain relatively low, suggesting that the variant will not meaningfully change Tesla’s third-quarter sales trajectory. That being said, Tesla China’s previous comments about the Model Y L’s demand suggest that an uptick in registrations may be coming in the next weeks.
The ramp of the Model Y L will likely be a notable topic among Tesla watchers, as its ramp will still be quite a task despite the vehicle being just a new variant of the all-electric crossover. With this in mind, meaningful numbers of Model Y L registrations may hit their pace in the next quarter instead.
Tesla China’s momentum
As per data from the China Passenger Car Association (CPCA), Tesla’s retail sales in August 2025 totaled 57,152 units. That figure marked a 9.9% decline from August 2024’s 63,456 units, but a significant 40.7% increase from July’s 40,617 deliveries.
Quarter-to-date, Tesla China’s results show a 34.4% gain compared to the previous quarter but remain down 11% year-over-year. Year-to-date, Tesla is down about 7% in China versus the same period in 2024. With only a couple more weeks before the end of the third quarter, Tesla China’s registrations may help determine whether the company could catch up to its 2024 numbers this year.

Tesla Supercharger access has proven to be a challenge for one company
Interestingly, it seems to be the Volkswagen brand specifically that is having issues with compatibility with Tesla Superchargers. Other brands under the VW umbrella, like Audi and Porsche, have already gained access to the charging network.

Tesla Supercharger access has proven to be quite the challenge for one company, as it continues to delay the date that it will enable its owners to charge at the most expansive network in the world.
Tesla Superchargers have been opening up to other brands for well over a year, and many car companies that are manufacturing electric vehicles now have access to the vast network that has over 70,000 locations worldwide.
Tesla to launch Supercharger access for VW owners later this year
However, one brand has experienced some issues with what it is calling “technical challenges,” specifically failing to enable cross-compatibility between its vehicles and Tesla Superchargers.
Volkswagen has had to delay its ability to enable customers to charge at Superchargers because there have been some difficulties getting things to run smoothly. A report from PCMag cites a quote from a Volkswagen spokesperson who said there are still plans to deliver this year, but there have been some delays:
“Volkswagen looks forward to making it possible for ID. Buzz and ID.4 vehicle owners to gain access to the Tesla NACS Partner Superchargers. The timeline has been delayed by technical challenges, and we ask for customers’ patience. We still expect to deliver access this year.”
Interestingly, it seems to be the Volkswagen brand specifically that is having issues with compatibility with Tesla Superchargers. Other brands under the VW umbrella, like Audi and Porsche, have already gained access to the charging network.
Volkswagen EV owners will need to use an official VW adapter to access the Tesla Supercharger Network once the issues are resolved. It still plans to launch access to its owners later this year, but its spokesperson did not announce any planned timeline.
