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.

SpaceX calls off Starship 10 flight attempt once again

SpaceX is calling off a potential launch of Starship this evening, marking the second consecutive night the tenth test flight of the massive rocket will be delayed.

SpaceX is calling off a potential launch of Starship this evening, marking the second consecutive night the tenth test flight of the massive rocket will be delayed.

Originally planning to launch on Sunday at 6:30 p.m. local time in Starbase, Texas, SpaceX was forced to delay the tenth launch of Starship due to a hardware issue.

“Ground side liquid oxygen leak needs to be fixed. Aiming for another launch attempt tomorrow,” CEO Elon Musk posted on the social media platform X.

The launch was then pushed to Monday night, and the launch window was set to start at the same time as Sunday. However, SpaceX would push it back to 6:44 p.m. due to some weather issues.

Eventually, Starship seemed like it was trending toward a launch, but weather continued to persist in the area, with thunder, rain, and lightning all threatening in the area.

At around 7:03 p.m., SpaceX decided to stand down once again, confirming weather was the culprit of yet another delay:

SpaceX will likely try again on Tuesday night, but the company has not yet confirmed if it will open another launch window.

WATCH: SpaceX Starship Flight 10 launch

SpaceX is set to launch its tenth test flight of the Starship program, with a launch window that will open at 6:44 p.m. local time, or 7:44 p.m. on the East Coast.

Starship’s tenth test flight was originally scheduled for launch yesterday with a one-hour window that opened at 7:30 p.m. ET, but it was called off 17 minutes before that window even had a chance to open.

SpaceX moved the flight to tonight. It was also originally scheduled to have a launch window at the same time as Sunday, but it was pushed back 14 minutes to around 6:30 p.m. ET. There are storms in the area, as well as clouds over Starbase, so there is the off chance for another launch delay.

There are several big objectives for this launch, including the expansion of the operating envelope for the Super Heavy booster. SpaceX says there are “multiple landing burn tests planned.”

The booster will also be performing a few in-flight experiments to help with data collection. Specifically, real-world performance data on future flight profiles and off-nominal scenarios will be on the list of things SpaceX will be looking for.

Starship itself will have a few in-flight objectives that include the deployment of eight Starlink simulators that are similar in size to the next-gen satellites for the internet service. SpaceX was set to test this with Starship’s seventh test flight, which occurred in January 2025. However, the task was abandoned as the vehicle was destroyed before deployment could occur.

Liftoff conditions are currently looking favorable, and SpaceX will be eager to improve upon its Starship launch program as CEO Elon Musk has big plans for it in the coming years.

Tesla looks to expand Robotaxi geofence once again with testing in new area

It looks as if Tesla is preparing for its next expansion of the geofence, potentially moving toward a much larger service area that could eclipse 150 square miles.

Tesla looks to be preparing for the potential expansion of the Robotaxi geofence once again, as the company was spotted testing the suite in an area well outside of the Austin service area.

After it first launched the Robotaxi platform on June 22, Tesla has managed to expand its geofence twice, essentially doubling the travel area both times.

The most recent expansion took the size of the geofence from 42 square miles to about 80 square miles, bringing new neighborhoods and regions of the city into the realm of where the driverless vehicles could take passengers.

However, it looks as if Tesla is preparing for its next expansion of the geofence, potentially moving toward a much larger service area that could eclipse 150 square miles.

Over the weekend, one fan noticed a Robotaxi validation vehicle testing in Bee Cave, Texas, which is roughly 25 minutes from the edge of the current geofence:

Tesla has been testing vehicles in the western suburbs of Austin for some time, and it seems the company is laying some groundwork to push its geofence expansion into Plaid Mode as competition with Waymo continues to be at the forefront of the conversation.

Waymo has been expanding with Tesla for some time, as the pace of expansion for the two companies has been relatively accelerated for the past couple of months.

Tesla’s expansions of the geofence sent a clear message to competitors and doubters, but it is still aiming to keep things safe and not push the envelope too quickly.

The geofence expansion is impressive, but Tesla is also focusing on expanding its vehicle fleet in both Austin and the Bay Area, where it launched a ride-hailing service in July.

Still, safety is the priority at the current time.

“We are being very cautious. We do not want to take any chances, so we are going to go cautiously. But the service areas and the number of vehicles in operation will increase at a hyper-exponential rate,” CEO Elon Musk said during the Q2 Earnings Call.
