Tesla Powerwall smarter integration with vehicle charging hinted at in API code

Recent observations from Tesla’s Powerwall API hint that the company’s electric cars will soon have a feature that will allow them to communicate better with the home battery system. With such a system in place, Tesla’s electric cars will not drain the Powerwall when the grid goes down.

The upcoming Powerwall and Tesla integration feature was first spotted by Model X owner and Reddit user u/cwiedmann.

“Looking through the data returned from the API, I see there’s now evidence of upcoming features for integrating Powerwalls and car charging as Elon mentioned. This appears to be support for preventing car charging from draining the batteries when the grid is down and maybe to allow the car to absorb surplus solar energy,” u/cwiedmann wrote on the r/TeslaMotors subreddit.

When the grid goes down, Tesla Powerwalls can meet the energy demands of a home, including charging an electric car like the Model 3, Model X, or Model S. That being said, there’s a big room for improvement especially when it comes to how a Tesla vehicle communicates with the home battery system. Tesla’s electric cars have massive battery packs after all, and they can drain an off-grid Powerwall if left unattended.

This appears to have happened in May 2019 to Tesla owner Erik Strait, who also runs the YouTube channel DӔrik. Strait brought up the Powerwall issue they encountered in Colorado and suggested features that may come handy to consumers, such as a setting that allows the home battery system to prevent cars charging when they are off the grid. Tesla CEO Elon Musk responded with a brief “Coming soon.”

Elon Musk posted his response to the Tesla owner-enthusiast last May, and there have been few updates on the feature since. Nevertheless, references to the feature in the Powerwall’s API today suggests that the home battery-electric vehicle integration may be coming sooner than expected. How the functionality will be rolled out remains to be seen too, but there’s a good chance that Tesla may introduce the feature through an over-the-air update, similar to how the company activates “Storm Watch” for Powerwall-equipped homes located in areas that are facing natural disasters.

Ultimately, the upcoming Powerwall feature shows that Tesla is making a lot of headway in integrating key features of its energy products and its electric cars. This ecosystem could ultimately encourage buyers of Tesla’s electric cars to adopt the company’s energy and battery storage products too, similar to how Apple has encouraged customers to purchase devices within its product line due to their feature integration.

These recent observations on the Powerwall API also invoke some thoughts on a feature that was mentioned by Elon Musk back in 2018. In a tweet then, Musk noted that it may be worth revisiting the idea of using its cars as batteries that output power, similar to a V2G (vehicle-to-grid) system. Tesla does seem to be exploring this idea recently, as hinted at by the Cybertruck’s capability to use its massive battery pack to power tools from its onboard outlets.

Teslarati will update you once the Powerwall-Tesla electric vehicle integration feature goes live. For now, this is a welcome development so the habit of “always be charging” does not lead one to a home without power. But of course, there’s always Camp Mode just in case.

Starlink will launch on United Airlines planes by May 15, 2025, providing select passengers with free internet inflight.

Recently, Sean Cudahy from The Points Guy tried out United Airlines’ free Starlink Wi-Fi. The airline invited a few media to try out Starlink Aviation Wi-Fi before its official launch.

According to Cudahy, connecting to Starlink was easy. All he had to do was take out his phone and connect to the Unitedwifi.com network, which took him to a landing page. Once he clicked “get started” on the landing page, it opened the United mobile app on his phone.

The United app verified Cudahy’s status as a MileagePlus member. After that, all he had to do was click on “connect,” and he was all set. Starlink’s speed was reliable and just what passengers would need on a long flight.

“I ran a speed test, and it clocked the Wi-Fi at 217 Mbps of download speed, and 26.8 Mbps of upload speed,” noted Cudahy.

Cudahy added that connection to Starlink Wi-Fi on his other devices, like his tablet, was easier. All he had to do was scan a QR code on his phone from his tablet.

“United certainly isn’t exaggerating on the speed of the service: I was able to simultaneously watch a live news feed about the selection of a new Pope on one device, and stream a live Major League Baseball game on another,” The Points Guy noted in his review of Starlink Aviation.

United Airlines is offering Starlink services for free to MileagePlus members. Based on Cudahy’s experience, it’s best to download the United mobile app before your flight.

United Airlines expects to equip all 300 of its Embraer 175 planes with Starlink by the end of the year. It plans to install 40 regional jets with Starlink equipment every month.

Last month, the Federal Aviation Administration (FAA) approved United Airlines’ Starlink-equipped planes. United plans to roll out Starlink Wi-Fi across all its flights. It is currently working to receive FAA approval to install Starlink equipment on over 16 aircraft models.

Ark Invest sees potential in xAI as the world adopts more AI models

Ark’s new stake in xAI bets on Musk’s future plans. Will the newly merged companies deliver the next AI breakthrough?

Ark Invest reinvested in X Corp in Q1 2025 through its Ark Venture Fund, which converted into a position in xAI, Elon Musk’s artificial intelligence company.

In March, xAI acquired X, intertwining the two companies’ futures. The stock merger values xAI at $80 billion and X at $33 billion. After xAI acquired X, Elon Musk noted that the combined company would unlock “immense potential.” Ark Invest believes in Musk’s vision for xAI and X Corp.

“…the deal created a new combined entity called XAI Holdings Corp., a strategic union that integrates xAI’s cutting-edge foundational models with X’s massive user base of over 600 million strong to unlock a platform that blends real-time communication with AI-enhanced discovery, truth-seeking, and personalized knowledge delivery.

“We believe this merger will be a significant catalyst for consumer AI adoption and foundational model monetization,” Ark noted.

Musk is reportedly planning a valuation adjustment for xAI. CNBC’s David Faber noted in April that Musk hinted at a new funding round for his artificial intelligence startup during an investor call.

The merger supports Musk’s vision to transform X into an “everything app,” where people can communicate, make monetary transactions, catch up on news, and more. xAI is already working on providing financial services. It recently partnered with TWG Global and Palantir to integrate AI with financial services.

In addition, XAI Holdings also has X Money, a payment system that could rival Venmo, Zelle, and Apple Pay. X Corp. secured a Visa partnership in January and money-transmitter licenses in 42 states, including California, in September 2024.

X Money faces opposition in New York from Manhattan Democrats Assemblymember Micah Lasher and state Sen. Brad Hoylman-Sigal, who sent a letter Monday to the state’s Department of Financial Services, urging rejection of X Corp.’s money-transmitter license. The lawmakers cited Musk’s leadership as a risk to consumer data and financial infrastructure.

Ark’s investment in xAI underscores confidence in its AI-driven future, amplified by the XAI Holdings merger. As xAI leverages X’s platform to scale AI innovation, Ark’s stake positions it to benefit from a transformative shift in consumer AI and fintech, despite ongoing challenges.
