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.

Investor's Corner

Tesla just got a weird price target boost from a notable bear

Tesla stock (NASDAQ: TSLA) just got a weird price target boost from a notable bear just a day after it announced its strongest quarter in terms of vehicle deliveries and energy deployments.

JPMorgan raised its price target on Tesla shares from $115 to $150. It maintained its ‘Underweight’ rating on the stock.

Despite Tesla reporting 497,099 deliveries, about 12 percent above the 443,000 anticipated from the consensus, JPMorgan is still skeptical that the company can keep up its momentum, stating most of its Q3 strength came from leaning on the removal of the $7,500 EV tax credit, which expired on September 30.

Tesla hits record vehicle deliveries and energy deployments in Q3 2025

The firm said Tesla benefited from a “temporary stronger-than-expected industry-wide pull-forward” as the tax credit expired. It is no secret that consumers flocked to the company this past quarter to take advantage of the credit.

The bump will need to be solidified as the start of a continuing trend of strong vehicle deliveries, the firm said in a note to investors. Analysts said that one quarter of strength was “too soon to declare Tesla as having sustainably returned to growth in its core business.”

JPMorgan does not anticipate Tesla having strong showings with vehicle deliveries after Q4.

There are two distinct things that stick out with this note: the first is the lack of recognition of other parts of Tesla’s business, and the confusion that surrounds future quarters.

JPMorgan did not identify Tesla’s strength in autonomy, energy storage, or robotics, with autonomy and robotics being the main focuses of the company’s future. Tesla’s Full Self-Driving and Robotaxi efforts are incredibly relevant and drive more impact moving forward than vehicle deliveries.

Additionally, the confusion surrounding future delivery numbers in quarters past Q3 is evident.

Will Tesla thrive without the EV tax credit? Five reasons why they might

Tesla will receive some assistance from deliveries of vehicles that will reach customers in Q4, but will still qualify for the credit under the IRS’s revised rules. It will also likely introduce an affordable model this quarter, which should have a drastic impact on deliveries depending on pricing.

Tesla shares are trading at $422.40 at 2:35 p.m. on the East Coast.

Tesla coding shows affordable model details, including potential price

Coding within Tesla’s website appears to have potentially revealed some details of the affordable model it plans to launch, including its possible price.

Although these details are unconfirmed by the company, recent sightings of the vehicle have sparked significant speculation as to what it will offer.

Tesla said a few months back that it had already successfully built the first few test units of the affordable model. CEO Elon Musk revealed later that it would essentially be a stripped-down version of the Model Y with a handful of changes.

We had our first look at what those changes appear to be, as what is likely the new affordable model was spotted on roads near Gigafactory Texas yesterday. It is a Model Y body with some Model 3 features.

It lacks the light bar that the new Model Y has and instead equips headlights similar to those of the Model 3 “Highland.”

Other design changes appear to include no glass roof and new wheels. Some rumors have also indicated that Tesla plans to use a cheaper, textile interior, devoid of the flashy features that its other cars are equipped with, including no rear screen, no HEPA system, and manually adjustable second-row air vents.

However, coding within the Tesla website seemed to reveal some pretty significant details about the new affordable model, including its name, which differs from the E41 codename it was given, its price, and a complete list of features.

This was found by Tesla Newswire on X. Here’s what the coding showed for the car. Note that this was found in coding, and is not necessarily confirmation from Tesla regarding what it plans to offer:

  • Name – Model Y Standard
  • Price $39,990
  • Redesigned front fascia
  • Single-part headlights
  • Front bumper camera
  • No glass roof, noted as a “closed glass roof”
  • 18″ Aperture wheels
  • Manually adjustable steering wheel
  • Textile décor
  • 15.4″ front touchscreen
  • No second-row touchscreen
  • Manually adjustable air vents in the second row
  • No HEPA system
  • 75 cu. fu. cargo space

Here’s what the coding looked like:

Many believe these could be the specs and details of the new affordable model, but others think Tesla might be baiting the community. Tesla knows its fans well, and many of them are sharp enough to examine some of the core portions of its website, looking for clues.

The company is well aware that these breadcrumbs will be discovered, and could be putting anything to drive up interest and chatter about what it could release. It certainly seems as if the price tag is a tad high, which tends to push some skepticism about the coding.

However, we’ll take anything we can get at this point. It is important to note that this coding is not a confirmation of details from Tesla.

The tea leaves seem to be pointing towards the imminent release of the highly anticipated affordable Tesla Model Y. This was hinted at in recent observations from notable Tesla influencers on social media, as well as a sighting of the vehicle without any camouflage.

The affordable Tesla uncovered

Sightings of the affordable Model Y have been abounding as of late, though details of the vehicle were still hidden by coverings on the vehicle. In a recent post on X from Firefly engineer Ryan Mable, however, noted Tesla influencer Sawyer Merritt has reportedly “spotted an uncovered cheaper Model Y variant” driving near Giga Texas. 

Several images of the uncovered vehicle were shared online. Based on the photos that were shared by Mable, the affordable Model Y seemed to feature a fascia that’s inspired by the Model 3 sedan. Its roof also looked blacked out. Overall, the vehicle had clean lines and it looked sleek, though it was also notably simpler than the standard Model Y.

Tesla influencer mystery

Interestingly enough, several Tesla influencers apart from Merritt posted that they were in Giga Texas. These included drone operator Joe Tegtmeyer, teardown specialist Sandy Munro, and reviewers Kyle Conner and Kim Java. These influencers have not provided any context behind their Giga Texas trip, though the fact that they were gathered on the site brought speculations that Tesla might have invited the group for a teaser or a private unveiling event of sorts.

It remains to be seen when the affordable Model Y would be made available, though conversations now are centered on the vehicle’s potential price. Previous reports suggested that the car might be priced just below $40,000, which many believe would result in very low sales, though some have also speculated that the affordable Model Y could be priced below $35,000, which would likely make it a strong seller.
