Hoping this is already in my 2023 Model 3 LFP and just need a software update.

Tesla Adds Vehicle-to-Load (V2L) Support to Model Y Performance

The new Tesla Model Y Performance is the first S3XY vehicle to get Vehicle-to-Load (V2L), a feature trickled from the Cybertruck, allowing it to power devices.

Tesla has prepared its onboard vehicle chargers for bidirectional charging, with capabilities confirmed for the new Model Y Performance released in August 2025. The technology has been present in Tesla's vehicles for some time but was not officially supported until recently. electrek.co greencarreports.com

Tesla's Bidirectional Charging Timeline
Initial Developments
  • 2015: Tesla co-founder JB Straubel mentioned that once Tesla's fleet reached 1 million vehicles, it would have significant controllable load capacity, hinting at future bidirectional capabilities.
Recent Confirmations
  • 2020: Reports indicated that Tesla's onboard chargers were designed for bidirectional charging, particularly in the Model 3, although the feature was not officially enabled.
  • 2023: Tesla announced plans to implement bidirectional charging capabilities across its entire lineup by 2025, indicating a shift in focus towards this technology.
Current Status
  • 2025: The new Model Y Performance was confirmed to support bidirectional charging, marking a significant step in Tesla's rollout of this technology.
Overall, while the technology has been in development for several years, Tesla has only recently begun to officially support bidirectional charging in its vehicles.

Tesla began implementing bidirectional charging capabilities in its vehicles, including the 2023 Model 3 RWD equipped with LFP batteries, as part of broader updates first rolled out in August 2025. Although the onboard chargers were capable of bidirectional charging, Tesla did not officially support this feature until recent updates, primarily introduced with the Model Y Performance in late August 2025.
The 2023 Model 3 RWD will receive this capability through over-the-air (OTA) updates, enhancing its utility for vehicle-to-load (V2L) applications. This rollout signified Tesla's move to encourage more flexible power management options for users, allowing them to power external devices.
If you need more detailed specs or features about the bidirectional use case, feel free to ask!

Your guess is almost certainly incorrect.

The PCS is what makes V2x possible.

The PCS for a Model 3/Y, which does not support V2x, sells for $1,750.

The PCS for a Cybertruck, which supports both 120V/20A and 240V/40A AC outputs, sells for $1,785. This suggests that Tesla's cost for the extra components necessary to support V2x may be less than $35.

Also, the Model Y Performance is not necessarily "nearly an $8K premium".

The MYP comes standard with features that cost extra on other trims. It's really about $2,500 more than the closest LRAWD, which gets you more than just V2L. See this post for details.

I would be very surprised if any previous or current non-Cybertruck Tesla models are capable of outputting AC. If my months-old Model Y isn't, I hope Tesla offers an upgraded PCS that supports this features at a significant discount.

Figure I should ask Grok. Guess not, at least not yet. :(

"No, the 2023 Tesla Model 3 Rear-Wheel Drive (RWD) does not have a bidirectional onboard charger. Tesla's Powershare system, which enables bidirectional charging for vehicle-to-home (V2H) and vehicle-to-load (V2L) functions, is currently only available on the Cybertruck and the newly released Model Y Performance (as of October 2025). The 2023 Model 3 lacks the required hardware, and Tesla has not announced any retrofits or software updates to enable it on pre-2024 models. While Tesla announced plans in 2023 to add bidirectional capabilities to all vehicles by the end of 2025, this hasn't been implemented for the 2023 Model 3 yet."

What’s interesting is that they chose to offer ONLY V2L and not V2H. Hope the article is not accurate as that’s such a weak addition. Offering a feature a 50lb $300 generator can offer isn’t really that big a deal, especially the huge price difference the Perf is now commanding.

Driving price down... by releasing a MYP with an $8.5k premium!? There're lots of things they can cut if the goal was to bring prices down, but it'll all be pennies compared to the core structure of the vehicle (shell, battery, motor). Most of that stuff (lights, 2nd screen, ventilated seats) are added costs that bring more value to buyers. V2H is still debatable, but I'd argue it's worth more than V2L marketing wise since V2L is just a $300 generator (that'd be available anywhere) vs a $300 mobile connector (that's limited to just where your vehicle is).

Another query to Grok. Since Grok is a spokesperson for Elon, this is what Elon thinks. KEK

No, you don't need to replace the Power Conversion System (PCS) in a 2023 Tesla Model 3 to enable Vehicle-to-Load (V2L) capability. The existing PCS hardware in Model 3 vehicles (including 2023 models) is already capable of supporting bidirectional power flow when paired with the right external setup, based on reverse-engineering analyses and recent trials showing successful V2G/V2H operation without internal modifications. Third-party V2L adapters are the most straightforward way to add this feature today.
How V2L Works on a 2023 Model 3 with Adapters
These adapters plug directly into your car's CCS or Type 2 charging port (depending on region) and "trick" the vehicle into discharging from the high-voltage battery. The adapter then converts the DC output to AC power for external devices. No disassembly, PCS swap, or internal wiring changes are required—it's a plug-and-play solution. Examples include:
  • Vortipower Adapter: Outputs up to 3.5 kW via two 120V/15A outlets. It auto-cuts off at 20% battery to protect the pack. Compatible with all Model 3 variants, including 2023.
  • Teslaunch V2L Discharge Device: Up to 3.6 kW output, supports multiple appliances. North America version available for ~$500–$600, with pre-sale discounts as of late 2024.
  • Other options: WeiDian Power 2 or A2Z EV adapters, which provide similar 3–3.5 kW output through one or two outlets.
These have been tested and reviewed positively for Model 3/Y/S/X, powering tools, camping gear, or small appliances during outages. Efficiency is around 90–95%, with minimal battery impact if you avoid deep discharges.
Feasibility and Limitations
  • Pros: Quick setup (under 5 minutes), no professional install needed, and works on unmodified 2023 Model 3s. Recent tests confirm compatibility without PCS changes.
  • Cons and Risks:
    • Warranty: Tesla's policy prohibits using the vehicle as a stationary power source, so adapters could void battery/drive unit coverage (8 years/100k–120k miles). Third-party makers like Vortipower note this risk but claim safe operation.
    • Power Limits: Typically capped at 3–3.6 kW (enough for a fridge, lights, or tools, but not heavy loads like EV chargers). Output stops at low battery to prevent damage.
    • Tesla Patches: Software updates could block these in the future, as speculated in owner forums.
    • No Native Support Yet: As of October 2025, 2023 Model 3s lack official V2L via OTA updates. Tesla rolled it out to the new 2025 Model Y Performance (V2L/V2H up to 11.5 kW), but older models like yours await potential retrofits. Elon Musk's 2022 promise for bidirectional across the lineup by end-2025 hasn't fully materialized for pre-2025 vehicles.
Alternatives If You Want Native or Higher-Power V2L
  • Wait for Tesla: If a retrofit program launches (e.g., via service center hardware/software upgrade), it might enable full V2H/V2L without adapters. No timeline for 2023 models yet.
  • External Systems: For V2H (home backup), pair with a Powerwall or third-party like Sigenergy, which enables bidirectional on unmodified Teslas.
  • Trade-In/Upgrade: Newer Highland Model 3s (2024+) or Juniper Model Y (2025+) are expected to get native V2L soon.
If you're handy, PCS replacement is possible (used/refurb units sell for $1,000–$2,000 on eBay), but it's unnecessary for V2L and involves coolant draining, high-voltage risks, and Tesla service tools—best left to pros. Stick with adapters unless Tesla announces a retrofit. Check Tesla forums or your app for updates.

I think I have to do some laughing now that Grok doesn't know the difference between AC and DC charging.
