Tesla poised to unlock vehicle-to-grid abilities with ‘bi-directional’ charging systems
It appears that Tesla is building up to the eventual release of vehicle to grid (V2G) features for its fleet. Hints of this technology could be seen in the codes within the company’s vehicles, as well as the recent findings of Cruise Staff fleet Reliability Engineer Marco Gaxiola, who happened to perform an analysis of Tesla’s electric vehicle charger for the Model 3.
For the most part, Tesla has been pretty quiet about its intentions to roll out a vehicle to grid feature for its fleet. Elon Musk mentioned that it may be worth revisiting V2G in a tweet back in July 2018, but he has been quite silent about the technology since then. That being said, Tesla hacker-enthusiast @greentheonly mentioned that some references to V2G have actually been in the company’s vehicles for over a year.
Among this is the presence of logic that would allow DC to flow out of a Tesla’s battery pack. The hacker-enthusiast summed up his observations as follows “There’s logic to allow DC to flow out the battery pack. So you can supply an external grid-tie invertor with that and let it do the rest of the magic. Making it part of the HPWC would make a lot of sense in my view,” he wrote.
Vehicle to grid features are not new in the EV sphere. The Nissan Leaf, one of the first mainstream electric cars, had this feature, though its V2G technology could be used more like a manual backup power supply. This made the Leaf’s V2G solutions rather limited. But when V2G is taken at scale, and if vehicles are in smart communication with the power grid, things become a lot more compelling.
Back in 2015, Tesla CTO JB Straubel noted that once there are a million Teslas on the road, the fleet could actually have significant controllable load capacity. This milestone was reached recently by Tesla, with the company producing its millionth vehicle, a red Model Y Performance, earlier this year. And considering that Tesla is now taking on the mainstream market with the Model Y and Model 3, there is a good chance that the growth of its fleet would only accelerate over time. If Tesla were to roll out V2G features for its cars, now, or the near future, would be a preferable time to do it.
But this is not all. In a recent statement to Electrek, Cruise Staff fleet Reliability Engineer Marco Gaxiola noted that the Model 3’s charger has the necessary technology to enable bidirectional charging features. Gaxiola came to his conclusions after doing a deep dive on the Model 3 charger. “What I learned on reverse engineering the Model 3 charger, was that the design is fully bidirectional. This means power can be converted from AC to DC the same way as the previous example, but also power can flow in reverse direction, coming from the battery and ending up on the AC side,” he told the publication.
In a following LinkedIn post, the Cruise engineer noted that Tesla would likely be able to roll out its V2G features to its fleet through a software update. This could open up a lot of opportunities for electric car owners, as they could actually sell some of their vehicles’ power back to the grid.
“I believe this will be a big game changer for all the car companies looking to get into the EV market. But will also be an interesting new road to get into the utility market. Imagine that you own this vehicle, and one morning you receive an update notification that will enable this feature, which will convert your vehicle into an energy storage V2G/V2V smart system with wheels.
“You will technically be able to take energy from any AC outlet at a good rate (via your traditional L1 or L2 wall charger) and later then drive somewhere else, plug back again into another L1/L2 charger, but instead of charging you could potentially sell some of your Tesla juice back at a higher rate. This, without the need of any electrical modifications on your Tesla/Non-Tesla wall charger,” Gaxiola wrote.

Tesla launches Cybertruck vehicle-to-grid program in Texas
The initiative was announced by the official Tesla Energy account on social media platform X.
Tesla has launched a vehicle-to-grid (V2G) program in Texas, allowing eligible Cybertruck owners to send energy back to the grid during high-demand events and receive compensation on their utility bills.
The initiative, dubbed Powershare Grid Support, was announced by the official Tesla Energy account on social media platform X.
Texas’ Cybertruck V2G program
In its post on X, Tesla Energy confirmed that vehicle-to-grid functionality is “coming soon,” starting with select Texas markets. Under the new Powershare Grid Support program, owners of the Cybertruck equipped with Powershare home backup hardware can opt in through the Tesla app and participate in short-notice grid stress events.
During these events, the Cybertruck automatically discharges excess energy back to the grid, supporting local utilities such as CenterPoint Energy and Oncor. In return, participants receive compensation in the form of bill credits. Tesla noted that the program is currently invitation-only as part of an early adopter rollout.
The launch builds on the Cybertruck’s existing Powershare capability, which allows the vehicle to provide up to 11.5 kW of power for home backup. Tesla added that the program is expected to expand to California next, with eligibility tied to utilities such as PG&E, SCE, and SDG&E.
Powershare Grid Support
To participate in Texas, Cybertruck owners must live in areas served by CenterPoint Energy or Oncor, have Powershare equipment installed, enroll in the Tesla Electric Drive plan, and opt in through the Tesla app. Once enrolled, vehicles would be able to contribute power during high-demand events, helping stabilize the grid.
Tesla noted that events may occur with little notice, so participants are encouraged to keep their Cybertrucks plugged in when at home and to manage their discharge limits based on personal needs. Compensation varies depending on the electricity plan, similar to how Powerwall owners in some regions have earned substantial credits by participating in Virtual Power Plant (VPP) programs.
Tesla is updating Cybertruck owners on its timeline of a massive feature that has yet to ship: Powershare with Powerwall.
Powershare is a bidirectional charging feature exclusive to Cybertruck, which allows the vehicle’s battery to act as a portable power source for homes, appliances, tools, other EVs, and more. It was announced in late 2023 as part of Tesla’s push into vehicle-to-everything energy sharing, and acting as a giant portable charger is the main advantage, as it can provide backup power during outages.
Cybertruck’s Powershare system supports both vehicle-to-load (V2L) and vehicle-to-home (V2H), making it flexible and well-rounded for a variety of applications.
However, even though the feature was promised with Cybertruck, it has yet to be shipped to vehicles. Tesla communicated with owners through email recently regarding Powershare with Powerwall, which essentially has the pickup act as an extended battery.
Powerwall discharge would be prioritized before tapping into the truck’s larger pack.
However, Tesla is still working on getting the feature out to owners, an email said:
“We’re writing to let you know that the Powershare with Powerwall feature is still in development and is now scheduled for release in mid-2026.
This new release date gives us additional time to design and test this feature, ensuring its ability to communicate and optimize energy sharing between your vehicle and many configurations and generations of Powerwall. We are also using this time to develop additional Powershare features that will help us continue to accelerate the world’s transition to sustainable energy.”
Owners have expressed some real disappointment in Tesla’s continuous delays in releasing the feature, as it was expected to be released by late 2024, but now has been pushed back several times to mid-2026, according to the email.
Foundation Series Cybertruck buyers paid extra, expecting the feature to be rolled out with their vehicle upon pickup.
Cybertruck’s Lead Engineer, Wes Morrill, even commented on the holdup:
As a Cybertruck owner who also has Powerwall, I empathize with the disappointed comments.
To their credit, the team has delivered powershare functionality to Cybertruck customers who otherwise have no backup with development of the powershare gateway. As well as those with solar…
— Wes (@wmorrill3) December 12, 2025
He said that “it turned out to be much harder than anticipated to make powershare work seamlessly with existing Powerwalls through existing wall connectors. Two grid-forming devices need to negotiate who will form and who will follow, depending on the state of charge of each, and they need to do this without a network and through multiple generations of hardware, and test and validate this process through rigorous certifications to ensure grid safety.”
It’s nice to see the transparency, but it is justified for some Cybertruck owners to feel like they’ve been bait-and-switched.
