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.

Tesla begins Robotaxi certification push in Arizona: report
Tesla seems serious about expanding its Robotaxi service to several states in the coming months.

Tesla has initiated discussions with Arizona transportation regulators to certify its driverless Robotaxi service in the state, as per a recent report from Bloomberg News. The move follows Tesla’s launch of its Robotaxi pilot program in Austin, Texas, as well as CEO Elon Musk’s recent comments about the service’s expansion in the Bay Area.
The Arizona Department of Transportation confirmed to Bloomberg that Tesla has reached out to begin the certification process for autonomous ride-sharing operations in the state. While details remain limited, the outreach suggests that Tesla is serious about expanding its driverless Robotaxi service to several territories in the coming months.
The Arizona development comes as Tesla prepares to expand its service area in Austin this weekend, as per CEO Elon Musk in a post on X. Musk also stated that Tesla is targeting the San Francisco Bay Area as its next major market, with a potential launch “in a month or two,” pending regulatory approvals.
Tesla first launched its autonomous ride-hailing program on June 22 in Austin with a small fleet of Model Y vehicles, accompanied by a Tesla employee in the passenger seat to monitor safety. While still classified as a test, Musk has said the program will expand to about 1,000 vehicles in the coming months. Tesla will later upgrade its Robotaxi fleet with the Cyercab, a two-seater that is designed without a steering wheel.
Sightings of Cybercab castings around the Giga Texas complex suggests that Tesla may be ramping the initial trial production of the self-driving two-seater. Tesla, for its part, has noted in the past that volume production of the Cybercab is expected to start sometime next year.
In California, Tesla has already applied for a transportation charter-party carrier permit from the state’s Public Utilities Commission. The company is reportedly taking a phased approach to operating in California, with the Robotaxi service starting with pre-arranged rides for employees in vehicles with safety drivers.

Tesla sets November 6 date for 2025 Annual Shareholder Meeting
The automaker announced the date on Thursday in a Form 8-K.

Tesla has scheduled its 2025 annual shareholder meeting for November 6, addressing investor concerns that the company was nearing a legal deadline to hold the event.
The automaker announced the date on Thursday in a Form 8-K submitted to the United States Securities and Exchange Commission (SEC). The company also listed a new proposal submission deadline of July 31 for items to be included in the proxy statement.
Tesla’s announcement followed calls from a group of 27 shareholders, including the leaders of large public pension funds, which urged Tesla’s board to formally set the meeting date, as noted in a report from The Wall Street Journal.
The group noted that under Texas law, where Tesla is now incorporated, companies must hold annual meetings within 13 months of the last one if requested by shareholders. Tesla’s previous annual shareholder meeting was held on June 13, 2024, which placed the July 13 deadline in focus.
Tesla originally stated in its 2024 annual report that it would file its proxy statement by the end of April. However, an amended filing on April 30 indicated that the Board of Directors had not yet finalized a meeting date, at least at the time.
The April filing also confirmed that Tesla’s board had formed a special committee to evaluate certain matters related to CEO Elon Musk’s compensation plan. Musk’s CEO performance award remains at the center of a lengthy legal dispute in Delaware, Tesla’s former state of incorporation.
Due to the aftermath of Musk’s legal dispute about his compensation plan in Delaware, he has not been paid for his work at Tesla for several years. Musk, for his part, has noted that he is more concerned about his voting stake in Tesla than his actual salary.
At last year’s annual meeting, TSLA shareholders voted to reapprove Elon Musk’s compensation plan and ratified Tesla’s decision to relocate its legal domicile from Delaware to Texas.

Grok coming to Tesla vehicles next week “at the latest:” Elon Musk
Grok’s rollout to Tesla vehicles is expected to begin next week at the latest.

Elon Musk announced on Thursday that Grok, the large language model developed by his startup xAI, will soon be available in Tesla vehicles. Grok’s rollout to Tesla vehicles is expected to begin next week at the latest, further deepening the ties between the two Elon Musk-led companies.
Tesla–xAI synergy
Musk confirmed the news on X shortly after livestreaming the release of Grok 4, xAI’s latest large language model. “Grok is coming to Tesla vehicles very soon. Next week at the latest,” Musk wrote in a post on social media platform X.
During the livestream, Musk and several members of the xAI team highlighted several upgrades to Grok 4’s voice capabilities and performance metrics, positioning the LLM as competitive with top-tier models from OpenAI and Google.
The in-vehicle integration of Grok marks a new chapter in Tesla’s AI development. While Tesla has long relied on in-house systems for autonomous driving and energy optimization, Grok’s integration would introduce conversational AI directly into its vehicles’ user experience. This integration could potentially improve customer interaction inside Tesla vehicles.
xAI and Tesla’s collaborative footprint
Grok’s upcoming rollout to Tesla vehicles adds to a growing business relationship between Tesla and xAI. Earlier this year, Tesla disclosed that it generated $198.3 million in revenue from commercial, consulting, and support agreements with xAI, as noted in a report from Bloomberg News. A large portion of that amount, however, came from the sale of Megapack energy storage systems to the artificial intelligence startup.
In July 2023, Musk polled X users about whether Tesla should invest $5 billion in xAI. While no formal investment has been made so far, 68% of poll participants voted yes, and Musk has since stated that the idea would be discussed with Tesla’s board.
