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.”
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.
Very early on, we had the ability to use the car as a battery outputting power. Maybe worth revisiting that.

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.

Elon Musk confirms Tesla Semi will enter high-volume production this year
Musk shared his update in a post on social media platform X.
Elon Musk has confirmed that Tesla will begin high-volume production of the Class 8 all-electric Semi this year.

Musk confirms Tesla Semi production ramp
Tesla CEO Elon Musk reaffirmed on X that the Semi is finally moving into volume production, posting on Sunday that “Tesla Semi starts high volume production this year.”
The update comes as Tesla refreshed its Semi lineup on its official website, an apparent hint that the program is transitioning from limited pilots into wider commercial deployment. As per Tesla’s official website, two variants of the Semi will be offered to consumers: Standard and Long Range.
The Standard trim offers up to 325 miles of range with an energy consumption rating of 1.7 kWh per mile and a gross combination weight rating of 82,000 pounds. The Long Range version pushes driving range to 500 miles, with Tesla noting a higher curb weight of about 23,000 pounds, likely due to a larger battery pack.
Both trims support fast charging, with Tesla stating that the Semi can recover up to 60% of its range in 30 minutes using compatible charging infrastructure.
Broader Tesla Semi rollout
Tesla has already delivered production Semi units to select partners, including snack and beverage giant PepsiCo as well as logistics behemoth DHL, which confirmed that its truck operates daily in California, traveling roughly 100 miles per day and requiring charging just about once a week.
The company has also partnered with Uber Freight, as noted in a Benzinga report, with Tesla executives previously describing the agreement as a way for fleet operators to experience the Semi’s lower operating and maintenance costs firsthand.
With Musk now publicly committing to high-volume production, the Semi appears poised to move beyond pilot programs and into scaled commercial use, an important step in Tesla’s wider push to electrify heavy-duty and long-range trucking.

Tesla tops France reliability rankings, beating Toyota for the first time
The milestone was celebrated by CEO Elon Musk on social media platform X.
Tesla has overtaken Toyota to become France’s most reliable car brand in 2025, as per a new nationwide reliability ranking published by Auto Plus magazine.
The milestone was celebrated by CEO Elon Musk on social media platform X.
Tesla tops reliability ranking in France
Tesla ranked first overall in Auto Plus’ 2025 reliability study, surpassing long-time benchmark Toyota across all powertrain types, including gasoline, hybrid, and electric vehicles.
The ranking, published on February 6, 2026, evaluated early problems reported in 2025 on vehicles registered in France since January 1, 2018, with fewer than 150,000 kilometers on the odometer, as noted by a Numerama report. This marked Tesla’s first appearance in the magazine’s reliability rankings, which was enabled by the company’s growing vehicle population in the French market.
According to the publication, Tesla vehicles showed no recurring major defects beyond isolated suspension arm issues, which are covered under the company’s four-year or 80,000-kilometer warranty. Other reported issues were described as minor, including occasional screen glitches and door handle concerns.
Why this ranking differs from earlier criticism
Tesla’s top placement contrasts sharply with past assessments from the German Automobile Club (ADAC), which previously ranked the Model 3 and Model Y low in its technical inspection reports. Auto Plus noted that those inspections were focused heavily on factors such as brake disc wear, which are not necessarily the best benchmarks for overall vehicle reliability.
By focusing instead on real-world reliability data and early ownership issues, Auto Plus’ methodology offered a broader picture of how vehicles perform over time rather than how individual components age under inspection standards. The publication emphasized that electric vehicles, with far fewer moving parts than combustion-engine cars, are not inherently less reliable.
While the ranking supports the case that electric vehicles can match or exceed the reliability of traditional brands, the magazine acknowledged limitations in its analysis. Still, Tesla’s debut at the top of the list underscores how perceptions of EV durability are shifting as more long-term data becomes available in major automotive markets like France.

Tesla’s Sweden standoff draws UAW support as unions widen pressure campaign
In a post shared on social media, the United Auto Workers stated that it stands with IF Metall workers who are striking against Tesla Sweden.
The United Auto Workers (UAW) has publicly expressed solidarity with Swedish union IF Metall as its strike against Tesla continues, adding international attention to the extended labor dispute in the European country.
UAW supports IF Metall’s strike
In a post shared on social media, the United Auto Workers stated that it stands with IF Metall workers who are striking against Tesla Sweden. UAW Region 8 Director Tim Smith stated that the union fully supports IF Metall’s efforts to secure a collective bargaining agreement with the automaker.
“UAW stands with IF Metall workers on strike against Tesla, fighting for a collective bargaining agreement. UAW Region 8 Director Tim Smith pledged the UAW’s full support and solidarity,” the UAW International Union stated in its post.
IF Metall launched its strike against Tesla Sweden in late 2023 over the electric car maker’s refusal to sign a collective agreement. The action has since been supported by other unions through sympathy strikes affecting ports, logistics, and service operations.
Tesla Sweden has maintained that it complies with Swedish labor laws and offers competitive pay and benefits, though the company has not publicly commented on the UAW’s latest show of support.
Tesla owners get union attention
Pro-union groups in Sweden have recently expanded their outreach beyond Tesla’s facilities and workforce. Activists have begun distributing informational leaflets against the EV maker directly on Tesla vehicles parked across Stockholm, as per a report from Swedish outlet Dagens Arbete.
The yellow slips, designed to resemble parking notices, urge regular Tesla owners to pressure the company into signing a collective agreement. Organizers involved in the effort have argued that the leaflets are intended to simply inform consumers rather than single out individual owners. When owners are present, however, activists stated that they explain the dispute verbally.
Tesla has not issued a public response regarding the leaflet distribution campaign as of writing.
