Tesla deliveries the first semi trucks to Pepsi Co
Tesla
The first Tesla Semis have been delivered, and so has the promise to adhere to the company’s mission: accelerate the advent of sustainable transportation. Yes, it took five years from the first peek at the Semi and three years longer than initially projected, but the Semi is set to change the trucking industry the same way the Model S, 3, X and Y changed the automotive industry.
While Tesla has been increasing the number of passenger vehicles it produces worldwide; these large trucks are not needed at the same level. The company states that 15 million passenger vehicles are sold in the U.S. every year, but only a couple hundred thousand big rigs. So why would Tesla put so much time and effort into something that doesn’t sell as many units?
Musk’s response, “it seems like a small percentage, but it (semi-trucks) is actually 20 percent of U.S. vehicle emissions. Because you’ve got a huge vehicle, and it’s being driven all the time.” Musk said, “Over a third of all the articulate emissions (are from semi-trucks). So, from a health standpoint, particularly in cities, this is a huge impact, like gigantic — that’s why we are doing it.”
The Semi is a Recruiting Tool for Truckers
Back in 2017, Elon Musk said he could drive a Tesla Semi. That was quite a statement, given that trucks this size usually come with anywhere from 10 to 18 gears. However, the CEO did just that five years later. He drove the newest member of the Tesla lineup to the event to deliver the Semi to Pepsi Co. Musk said, “It’s like driving a Tesla, literally.” That is because it’s built the same way with a single stalk to put the vehicle in drive, reverse, neutral or park. “It looks sick. I mean, you want to drive that! That thing looks like it came from the future… It’s fun. It looks awesome, there is a big shortage of drivers, so if you are a truck driver and want the most bad ass rig on the road - this is it.”
The Semi is known as the Beast
Senior Manager of Tesla’s Semi Engineering, Dan Priestley, explained why many people refer to the Semi as the beast. “(It has) three times the power than any diesel truck on the road right now. So you’ve got all the power you need to get the job done, but the other reason that it’s a beast is because it is efficient, you can go 500 miles on a single charge on one of these things. It’s the mix of those two - this is a game-changer. What’s awesome is both of those are enabled by our 1000-volt powertrain. This is the first vehicle we are doing with that.”
That max power combined with hyper-efficiency is due to a tri-motor power train system. One motor is for highway driving and will always be engaged, while the other two are for torque and acceleration. Those motors use the system straight out of the Model S Plaid powertrain. Priestly said, “These are clutched automatically. No driver input is needed. It is seamless.”
Musk commented on the Semi’s performance, “It looks crazy. It looks like an elephant moving like a cheetah.” He was also astonished at the size of the motor powering the Semi. It’s described as the size of a football, “I find it amazing that this enormous thing can be pulled by something that you can carry in your hands — it’s like, wow, that is power density.”
500-mile Range
The Semi has been tested in all conditions in the real world, in a lab and virtually. One of those real-world tests was proving the naysayers wrong by taking the Semi for a 500-mile drive, fully loaded, from Fremont to San Diego on just a single charge.
Elon Musk later revealed on Twitter that the Tesla Semi's current efficiency is about 1.7kWh/mile, but that there is a path for Tesla to make it even more efficient. It's not clear whether the additional efficiency could be achieved through software or if it would require hardware changes. The quoted 1.7kWh/mile efficiency is a pleasant surprise, as many were expecting the truck to have an efficiency of about 2kWh per mile.
V4 Superchargers
Speaking of charging, the new V4 Superchargers were also revealed. They produce 1 megawatt of energy and will be used for the Semi and the Cybertruck.
Tesla's Semi Delivery Event
Musk finished the event with this message: This is going to revolutionize the road, make the world a better place in a meaningful way.
Tesla has filed four patents for wireless charging. Previously, Tesla acquired the experience and skills of Wiferion’s engineering team in an acquisition in June 2023. Tesla quickly sold off the company but kept the company’s engineers. This was an acqui-hire, where large companies rapidly onboard top talent by purchasing a company for human capital, rather than products, services, or intellectual products.
Following the Wiferion acquisition, Tesla showed off a wireless charging mat several times and even confirmed they are working on wireless inductive home charging. We expected this to arrive with the Cybertruck, but now we hope to see more details at the upcoming Robotaxi reveal event in October, at the Warner Bro.’s studio in Hollywood.
Wireless Charging Patents
First Patent
The first of the four patents looks at temperature sensors and applications for wireless charging. Tesla intends to track the temperatures across both the wireless charging pad, as well as the inductive charging coils in the vehicle. The third patent details how they’re planning to use this in an innovative way.
WIPO
Second Patent
The second patent is a shorting switch, which is designed to prevent or reduce leakage of energy to ground sources near the wireless charging mat. This shorting switch is used to create a short with the receiving side of the inductive charging, essentially making energy transfer faster and more efficient – while also reducing the amount of energy that is leaked out elsewhere. We’ll leave this one for the electrical engineers to explain in our forums.
Third Patent
The third patent is actually the wireless charging circuit itself, and how to manufacture it. This one is straightforward and explains how Tesla intends to design and build the prototype inductive wireless charging mats. Beyond the basic design, this document also details how Tesla intends to lay out the inductive charging coils and how it expects the entire assembly to function – which includes a small cable that runs to a wall-mounted energy source.
Fourth Patent
The final patent is for intelligently estimating and adapting to variations in wireless charging layouts and systems. This one is probably the most interesting of the four patents, as it involves adjusting the coils in the mat to dynamically account for the positioning of the vehicle, as well as responding to the information from the first patent – the temperature sensors.
Essentially, by varying the coil induction across the mat, Tesla intends to dynamically aim the wireless charger at different parts of the inductive coils in the vehicle, thereby reducing heat. This patent will also help Tesla to determine the adequate charge speed and other key information they may need to relay to the vehicle, or back to fleet management software.
Cybertruck Inductive Charging
While the Cybertruck never actually arrived with inductive charging, it was noted in the Service Manual to have 2 Inductive Charging Headers, so it is ready to be upgraded to have Inductive Charging support. We expect that Tesla will release this as a purchasable upgrade for the Cybertruck sometime in the future – likely as a package with the Inductive Charging Mat.
Robotaxi Inductive Charging
The Robotaxi will likely be the first of Tesla’s vehicles to feature inductive charging – which. makes sense given its autonomous nature. Plugging in a NACS charger will likely be fairly difficult to automate, and the 5-10% efficiency loss of wireless charging isn’t a huge deal. It’s possible Tesla chose this route due to cost, as having an automated NACS cable like the “snake” prototype we saw years ago could be costly.
Having a simple parking stall with an inductive mat on it, alongside all the tech and supplies needed to automatically clean and sanitize the Robotaxi makes far more sense. This means that a Robotaxi will be able to roll in, charge and clean itself, and then roll out to go pick up more customers. Tesla is planning a super-efficient system here that requires minimal intervention from real humans.
Essentially, by effectively managing the Robotaxi fleet, Tesla can offset the increased time that wireless charging would take, and also reduce the amount of waste energy by charging when energy is cheapest. While this could prevent Tesla from taking advantage of the sheer battery mass of a Robotaxi fleet – by selling power when it’s expensive and travel demand is low – this doesn’t make it impossible.
Smartphone manufacturers have demonstrated reverse wireless charging with the inductive charging coils already present in modern smartphones. We could see Tesla low-power bi-directional charging in the future too.
We’re looking forward to seeing Tesla unveil this at the upcoming Robotaxi event. It’ll be something special, for sure.
Tesla has made a spate of improvements to its vehicle software recently, starting with the big Spring Update, and then the Summer Update more recently. While we see most of the updates mentioned in the release notes, Tesla often also adds smaller quality-of-life improvements along the way.
Browser Controls
When using the Tesla Browser in the vehicle, you can now swipe left and right to go back or forward a page in your browser history. When you start swiping on the screen, Tesla’s Chromium-based browser will now display an arrow that slides out from the left or right. The circular icon is initially white, meaning that the action won’t be executed, but if you continue moving to the left/right, the icon will eventually turn blue. The blue icon means that the action will be executed once you let go of the screen.
This is a simple quality-of-life improvement that makes using the built-in browser easier.
We’re happy to see updates like these come to the browser, whose last major feature was the full-screen button that was added in update 2024.14.
Future Browser Improvements
While we’re on the topic, let’s look at some future Tesla web browser improvements we’d love to see.
Access to the Mic
Full access to the vehicle microphone isn’t allowed through the web browser right now. That means if you want to get into a Discord, Slack, or Teams call, you’ll only be able to listen – not speak. All of these apps fully function in the Tesla browser for sending messages, but are fairly limited for meetings.
Better Bookmarks
Tesla’s current bookmark system is simple and barebones. You can bookmark a page and give it a name. Once you visit a bookmarked page enough, it’ll show up as an icon in the center of the browser when you go to the homepage.
However, it's difficult to keep a larger set of bookmarks since there aren’t any organizational tools provided. A better bookmark system or the ability to sync bookmarks would be a welcomed feature.
Custom Homepage
Tesla’s current homepage in its browser is simply just a Tesla logo in black or white, depending on whether your car is in dark mode or not. A custom homepage that provides widgets with basic local news, stock information or other details would be fantastic. We’d ask for weather too, but the recent Summer update shows weather at the top of your screen.
If you’ve got more ideas for the fairly barebones Tesla web browser, let us know.
