Update: Tesla Semi’s ad hoc ‘Megacharger’ setup spotted in the open at Supercharger

Perhaps one of the most secretive aspects of the Tesla Semi is its charging system. Since the vehicle’s unveiling, Tesla has been particularly careful about the ad hoc setup adopted by its Semi prototypes when they recharge their batteries at the company’s Supercharger Network. But with the Class 8 all-electric truck poised for volume production soon, it appears that Tesla has become a bit more generous in allowing EV enthusiasts to share photos of the vehicle’s charging setup. 

Correction: We have been informed that the image of the Semi’s ad hoc Megacharger setup was photographed and shared on social media in February 2019. A report of the sighting was posted by Jeff Nisewanger on Electric Revs.

Edmonton, AB-based Tesla Model 3 owner @TeslaYeg, an avid enthusiast of the electric car maker’s vehicles, recently posted a photograph of the Tesla Semi as it was charging at a Supercharger station. The Model 3 owner did not specify the location where the image was taken, though it would appear that the Semi was in Canada when it was photographed. This is not too farfetched, as the vehicle has been spotted road testing in Canada not too long ago. 

When the Tesla Semi was unveiled back in 2017, Elon Musk stated that the company will be setting up a network of “Megachargers” that would support the rapid charging needs of the Class 8 truck. The status of the company’s Megacharger ramp is unknown for now, though sightings of the vehicle across the United States indicate that Tesla has been using multiple regular Supercharger stalls as an ad hoc solution for the Semi’s charging needs. 

Unfortunately, Tesla has previously been very secretive about how this ad hoc solution works or even looks like. Some Tesla owners who were fortunate enough to chance upon the Semi at a Supercharger in the past even mentioned that staff and engineers accompanying the Class 8 truck have specifically asked them not to take any pictures of the vehicle’s charger. This does not seem to be the case anymore, as per @TeslaYeg’s recent post on Twitter.

The ad hoc “Megacharger” being used in the Semi actually features a pretty compact setup, with the company using a box that bridges the cables from the Supercharger stall to the truck itself. Interestingly, the charge port connector attached to the Semi appears to have enough space for two cables, and the box that links the charging stall to the truck seems to have enough space to accommodate several Superchargers as well. 

The next few months will likely be exciting for the Tesla Semi, considering that Elon Musk has announced that the vehicle should enter volume production soon. Recent sightings of the vehicle indicate that prototypes of the all-electric truck are being winter tested, and details of the Semi’s battery tech are expected to be discussed during the highly-anticipated Battery Day event this coming September. This suggests that a production ramp for the Semi is indeed underway, and it will only be a matter of time before the Class 8 truck starts being a common sight on freeways.

Tesla adds 15th automaker to Supercharger access in 2025

Tesla has added the 15th automaker to the growing list of companies whose EVs can utilize the Supercharger Network this year, as BMW is the latest company to gain access to the largest charging infrastructure in the world.

BMW became the 15th company in 2025 to gain Tesla Supercharger access, after the company confirmed to its EV owners that they could use any of the more than 25,000 Supercharging stalls in North America.

Newer BMW all-electric cars, like the i4, i5, i7, and iX, are able to utilize Tesla’s V3 and V4 Superchargers. These are the exact model years, via the BMW Blog:

  • i4: 2022-2026 model years
  • i5: 2024-2025 model years
    • 2026 i5 (eDrive40 and xDrive40) after software update in Spring 2026
  • i7: 2023-2026 model years
  • iX: 2022-2025 model years
    • 2026 iX (all versions) after software update in Spring 2026

With the expansion of the companies that gained access in 2025 to the Tesla Supercharger Network, a vast majority of non-Tesla EVs are able to use the charging stalls to gain range in their cars.

So far in 2025, Tesla has enabled Supercharger access to:

  • Audi
  • BMW
  • Genesis
  • Honda
  • Hyundai
  • Jaguar Land Rover
  • Kia
  • Lucid
  • Mercedes-Benz
  • Nissan
  • Polestar
  • Subaru
  • Toyota
  • Volkswagen
  • Volvo

Drivers with BMW EVs who wish to charge at Tesla Superchargers must use an NACS-to-CCS1 adapter. In Q2 2026, BMW plans to release its official adapter, but there are third-party options available in the meantime.

They will also have to use the Tesla App to enable Supercharging access to determine rates and availability. It is a relatively seamless process.

Tesla adds new feature that will be great for crowded parking situations

This is the most recent iteration of the app and was priming owners for the slowly-released Holiday Update.

Tesla has added a new feature that will be great for crowded parking lots, congested parking garages, or other confusing times when you cannot seem to pinpoint where your car went.

Tesla has added a new Vehicle Locator feature to the Tesla App with App Update v4.51.5.

This is the most recent iteration of the app and was priming owners for the slowly-released Holiday Update.

While there are several new features, which we will reveal later in this article, perhaps one of the coolest is that of the Vehicle Locator, which will now point you in the direction of your car using a directional arrow on the home screen. This is similar to what Apple uses to find devices:

In real time, the arrow gives an accurate depiction of which direction you should walk in to find your car. This seems extremely helpful in large parking lots or unfamiliar shopping centers.

Getting to your car after a sporting event is an event all in itself; this feature will undoubtedly help with it:

Tesla’s previous app versions revealed the address at which you could locate your car, which was great if you parked on the street in a city setting. It was also possible to use the map within the app to locate your car.

However, this new feature gives a more definitive location for your car and helps with the navigation to it, instead of potentially walking randomly.

It also reveals the distance you are from your car, which is a big plus.

Along with this new addition, Tesla added Photobooth features, Dog Mode Live Activity, Custom Wraps and Tints for Colorizer, and Dashcam Clip details.

All in all, this App update was pretty robust.

Tesla CEO Elon Musk shades Waymo: ‘Never really had a chance’

Tesla CEO Elon Musk shaded Waymo in a post on X on Wednesday, stating the company “never really had a chance” and that it “will be obvious in hindsight.”

Tesla and Waymo are the two primary contributors to the self-driving efforts in the United States, with both operating driverless ride-hailing services in the country. Tesla does have a Safety Monitor present in its vehicles in Austin, Texas, and someone in the driver’s seat in its Bay Area operation.

Musk says the Austin operation will be completely void of any Safety Monitors by the end of the year.

With the two companies being the main members of the driverless movement in the U.S., there is certainly a rivalry. The two have sparred back and forth with their geofences, or service areas, in both Austin and the Bay Area.

While that is a metric for comparison now, ultimately, it will not matter in the coming years, as the two companies will likely operate in a similar fashion.

Waymo has geared its business toward larger cities, and Tesla has said that its self-driving efforts will expand to every single one of its vehicles in any location globally. This is where the true difference between the two lies, along with the fact that Tesla uses its own vehicles, while Waymo has several models in its lineup from different manufacturers.

The two also have different ideas on how to solve self-driving, as Tesla uses a vision-only approach. Waymo relies on several things, including LiDAR, which Musk once called “a fool’s errand.”

This is where Tesla sets itself apart from the competition, and Musk highlighted the company’s position against Waymo.

Jeff Dean, the Chief Scientist for Google DeepMind, said on X:

“I don’t think Tesla has anywhere near the volume of rider-only autonomous miles that Waymo has (96M for Waymo, as of today). The safety data is quite compelling for Waymo, as well.”

Musk replied:

“Waymo never really had a chance against Tesla. This will be obvious in hindsight.”

Tesla stands to have a much larger fleet of vehicles in the coming years if it chooses to activate Robotaxi services with all passenger vehicles. A simple Over-the-Air update will activate this capability, while Waymo would likely be confined to the vehicles it commissions as Robotaxis.
