Tesla Giga Nevada images hint at potential mobile “Megacharger” solution
New images from Giga Nevada suggest that Tesla may be looking to develop a mobile “Megacharger” system for the upcoming Class 8 all-electric Semi. The system seems to be powered by Powerpack batteries.
To clarify, the “Megacharger” is the name of the Semi’s charging infrastructure, as mentioned by CEO Elon Musk during the vehicle’s unveiling in late 2017. Pictures shared with Teslarati show Tesla’s progress with the buildout of Megachargers at Giga Nevada–and maybe a little more. There are a least two Megachargers at the Gigafactory, and Tesla might install more in the future, especially as the Semi’s limited production starts rolling.
However, right behind the Megachargers is a trailer with four Tesla Powerpacks and two urban charger stalls. According to Teslarati’s source, there were two trailers at Giga Nevada, and one of the trailers was fitted with Tesla Powerpacks, which may hint at a potential portable charging system.

Tesla’s Mobile Charger Solutions
Tesla has deployed mobile EV charging systems in the past. In 2019, Tesla deployed mobile Superchargers powered by Megapacks for the holidays. It was a simple and practical solution to increase the number of charger stalls at select Supercharger stations quickly and efficiently. Reports then indicated that the Megapack-powered mobile Superchargers could charge about 60-100 vehicles thanks to the Megapack’s 3 MWh capacity.
Mobile “Megachargers” would be a practical move for Tesla and the Semi’s clients. Mobile “Megachargers” could help top-up Semis in popular transport routes while Tesla concentrates on growing its Supercharger Network and the Semi’s dedicated charging infrastructure. Mobile “Megachargers” could also be a cost-effective way for Tesla and the Semi’s clients to ensure that chargers are present for the Class 8 electric truck in locations where they are needed the most.

The Semi’s “Megacharger” Evolution
In 2018, a Tesla Semi prototype sighted in Des Moines, IA was spotted using an ad hoc “Megacharger” system that utilized 5 Supercharger V2 stalls. By 2020, sightings of the electric Class-8 revealed an updated ad hoc “Megacharger” solution that used only 2 Supercharger stalls. It was unknown whether the two stalls charging the Semi in 2020 were V2 or V3 Superchargers.
The trailer in the picture recently shared with Teslarati held two urban chargers, suggesting a potentially similar charging setup as the Semi prototype spotted in 2020. As for the use of Powerpacks instead of larger Megapacks, it might be down to cost.
Tesla Semi’s updated ad-hoc Megacharger setup hints at vastly improved battery unit
According to Elon Musk during a 2021 interview with noted podcast host Joe Rogan, the Semi’s 300-mile variant should be equipped with a battery pack that’s around 500 kWh. Previous estimates suggested that the Semi will be fitted with a 600 kWh battery pack for the 300-mile version and a 1 MWh battery pack for the 500-mile Semi variant.
One Megapack has a capacity of 3 MWh and costs about $1.2 million as of July 2021, when Tesla updated the Megapack’s order page. A single Megapack could potentially charge several Semis consecutively, but the costs for such a solution would be substantial. Considering that one Tesla Powerpack has a capacity of up to 232 kWh, four units of the commercial-grade battery would likely have about ~900 kWh of energy capacity. This would likely be enough to top up a couple of Semis at a time, without requiring the full costs of a Megapack-powered system.

Tesla Phone? Not quite, but close: analyst
For years, there have been images and videos across social media platforms that have reminded me of when I was a 15-year-old kid teased by “Xbox 720” videos on YouTube. These videos are of the supposed “Tesla Phone” that Elon Musk was secretly developing in between leading Tesla with its electric cars and SpaceX with its reusable rockets.

Although Musk has put those rumors to bed several times, it was never completely out of the realm that he could get involved in cell phones in some capacity. Think outside the box and more macro-level, though. Instead of reinventing the computer, Musk reinvented connectivity by developing Starlink with SpaceX.
It could be something similar, TD Cowen analyst Gregory Williams said in a note last week, where he hinted SpaceX could be gathering some steam to acquire T-Mobile.
Williams said it would be the “clear choice” for SpaceX if it decided to go through with a network acquisition. He also suggested AT&T.
The move would be possible through selling more of its own stock, which would help SpaceX raise the money to purchase T-Mobile, which would cost roughly $300 billion. It could be one of the moves SpaceX makes post-IPO in terms of an acquisition: it already acquired Cursor AI for $60 billion.
Other analysts, like Dan Ives of Wedbush, believe SpaceX and Tesla will eventually merge into one anyway, and that conglomeration could come as soon as this year, some have said.
The implications of SpaceX purchasing T-Mobile are massive. A combined entity would create a truly ubiquitous network: T-Mobile’s terrestrial 5G towers and Starlink’s growing constellation of Direct-to-Cell satellites. This would essentially eliminate dead zones across the U.S. and potentially globally.
SpaceX would instantly become a full-scale facilities-based carrier with satellite differentiation; a huge advantage. This would pressure AT&T and Verizon heavily.
There are also concerns like a potential reduction in long-term competition, and of course, a deal of that size would face intense scrutiny from government agencies.
The strategic fit is compelling due to the existing Starlink–T-Mobile partnership and complementary technologies (space + terrestrial). It could create a dominant integrated communications player. However, the regulatory, financial, and execution hurdles are enormous — this remains highly speculative with no indication SpaceX is actively pursuing it right now.

Tesla reveals huge Cybercab detail in new guide for First Responders
Tesla revealed a major new Cybercab detail in a guide it released for First Responders, showing new territory in its beliefs and intentions for the ride-hailing-focused vehicle that entered production in April.
The First Responders Guide is released to give fire departments, paramedics, and other emergency personnel the proper guidance on what to do in the event of an accident, entrapment, or other situation that would require immediate attention.
On one of the pages of the First Responders Guide, Tesla revealed a stark detail about the Cybercab, which could help personnel enter the vehicle more easily in case of an emergency.
Tesla Cybercab has one important piece that AI4 cars might need for FSD
It shows Tesla has no intention of releasing any Cybercab units that were initially proposed for ride-hailing services for the general public with any manual controls, meaning a steering wheel or pedals:
“A Cybercab equipped with steering wheel, brake pedal, and an acceleration pedal is typically an engineering or test vehicle, and operates at SAE Level 2 autonomy. Cybercab is not typically equipped with a steering wheel or acceleration and brake pedals.”

This is a major development for those who continue to believe Tesla planned to release the Cybercab with any sort of manual controls so that passengers could take over if needed. However, when Tesla started manufacturing production versions of the Cybercab in Giga Texas earlier this year, they were spotted without a steering wheel or pedals.
It essentially confirms the company has no intentions of bringing manual controls to the car’s production versions. Some have argued that the likelihood of Tesla having something
There still are some Cybercab units out there with a steering wheel and pedals, and as Tesla said, these cars are engineering or test vehicles, which have Safety Monitors on board to help the car out of a precarious situation or emergency.

Tesla Full Self-Driving v14 ‘Lite’ Release Notes: new capabilities and features
Tesla released the Full Self-Driving v14 ‘Lite’ suite to owners of Hardware 3 or AI3 vehicles today, adding several new features to the vehicles that were once believed to be capable of unsupervised self-driving.
Now, Tesla has released this modified suite to older Tesla vehicles, adding plenty of new features and capabilities.
Here are the full release notes for the suite:
- Distilled the intelligence from HW4 V14 into HW3. This allows HW3 to directly learn how to handle scenarios using HW4 V14 as a guide. This process unlocks the improvements that have been made to HW4 including Reinforcement Learning (RL) and offline models for HW3.
- Improved both proactive and reactive responsiveness across a wide variety of categories including navigation handling, merges and forks, pedestrian interactions, traffic lights, and vehicle cut-in scenarios.
- Improved general comfort in nominal scenarios through fewer false slowdowns, smoother steering and more consistent lane centering.
- Introduced parking, unparking, and reversing capabilities.
- Added Arrival Options for you to select where FSD should park: in a Parking Lot, on the Street, in a Driveway, or at the Curbside.
- Speed Profiles are now available at all times, to further customize driving style preference.
These improvements, according to Tesla’s Head of AI, Ashok Elluswamy, help distill the driving behavior from AI4’s v14 series into both the camera and compute configurations of AI3.
Tesla Full Self-Driving v14 ‘Lite’ for older cars finally gets released
He added:
“It includes destination options and speed profiles on city roads, but more importantly significantly improved safety. We hope you’ll enjoy it, once the build ships wide.”
FSD v14 Lite is now rolling out to AI3 early-access customers. Based on the feedback, will rollout to more customers over the next few weeks.
