Stop worrying about Tesla Supercharger congestion, it will be alright

Tesla Supercharger in Antwerp-Aartselaar, Belgium

If you’ve ever heard the phrase “a solution looking for a problem” then you’ll completely understand what I’m about to say. While I’m at it with catchphrases, Tesla seems to be a living, breathing double-edged sword. When it comes to giving us details, they are “damned if they do, damned if they don’t.”

By now, we all know the Model 3 is going to be huge. We also know that Model S and X vehicles with Supercharging enabled can enjoy “free long distance travel,” which we understand to mean “free for life.”  The not so subtle elephant in the room is that free could lead to abuse, which could lead to lines and waiting for Supercharger use. I’ve already discussed what I think is step 1, which is educating folks on some Supercharging best practices they can do to be mindful of our shared asset. I’ve also discussed things Tesla themselves could do to alleviate potential congestion at Supercharger locations.

Here’s my disclaimer: This is a solution looking for a problem! Model 3 is more than a year away and despite what you may hear, MOST superchargers have one or more stalls available MOST of the time. Long waits and lines only plague select locations, and even then, only occur on very few occasions. While I’m no record-holding Supercharger pro I’ve only ever seen an 8-stall location full once. It was Hamilton, NJ and it was before the addition of two Superchargers on the nearby New Jersey Turnpike. I’ve also only ever known of one location to be constantly busy. It was the Newark, DE location, which has recently been upgraded from 4 to 12 stalls. So again, I don’t think this is a problem right now. I don’t even think it will be much a problem when Model 3 hits the streets. Tesla builds new chargers all the time and has committed to both distance and density. They know, more than anyone, which locations are busy and which aren’t. I trust they will plan accordingly.

You will be OK

But since folks love to debate every word – or lack thereof – that Tesla says, let’s have at it. Let’s pretend that the big bad wolf will come to the charger and blow it down just because it’s free and unrestricted once you incur an up-front cost. Let’s further pretend that Tesla considers the idea of a pay per use model of charging. I’ll repeat this later but for the record, I don’t think they’ll do anything like this. Not now, not ever.

  • Pay Per Use – kWh. This is a common and seemingly simple idea. You don’t need $2,000 worth of electricity, you only need a few bucks worth a few times a year. You don’t want to pay up front for all the phantom local moochers that you suspect will abuse an unrestricted system. The cars are smart, they can tell how much you’ve used per charging session so it appears they can charge you for it on the basis of that. Maybe you don’t even care if there is a huge markup on the electricity. It’s a win for everyone in that case, because it’s still cheaper than gas. Even if it wasn’t, it’s worth it to take a car as great as a Tesla on a road trip. Plus almost all of your charging is done at home where it’s way cheaper than gas. Fine, points taken. Except, there’s a “but.” But selling electricity is complicated. The United States is complicated! Here, we have 50 states and plenty of lines between them. They get to set their own laws and rules and tax rates. Cities and towns do too. If you thought that gaining approval to build a supercharger was a challenge, imagine trying to become an energy supplier in every municipality as well. This alone is enough to rule out the idea of charging per kWh. Add that in with having to handle point of sale transactions and you’ve completely changed how Tesla must operate. It already takes quite a bit of effort to build out this network, and there is no reason to make it harder. (Let’s pretend that’s why no other automakers have done it.)

Tesla builds new chargers all the time and has committed to both distance and density

  • Pay Per Use – Time. There’s a pretty clear precedent for selling time at almost any major municipality on earth: paid parking. In theory, it would result in very few people charging past 90%; that point where your electrons slow drastically and you’d get a lot less bang for your buck. This speaks perfectly to the concept of battling lines with quick turnover. Except, nope. Tesla, in my opinion, won’t be willing or interested in the hassle of point of sale purchases. They’d have to figure out an appropriate price, which I imagine would vary by location. They’d have to employ people to figure out the tax rules and rates for each country, state and city. They’ve have to work with various credit card companies and be able to accept multiple forms of payment. They may even need to carry certain types of liability insurance for providing paid parking. Tesla is in the business of advancing sustainable transport by, primarily, making compelling electric vehicles. Anything else is just noise and takes away brainpower from doing other great things.
  • Pay Per Use – Day. Tesla is amazing and has done plenty of things no other company has done before. They continue to surprise us and have stayed alive despite many assumptions that they’d never make it this far. So I’ll humor you, dear reader, and assume they are willing and able to take on the challenges of point of sales purchases. Game on! Rather than selling time or electricity, Tesla can simply sell access to software. Most Teslas on the road, and all that will soon be on the road, will have the hardware required for supercharging. They can undoubtedly figure out how to program an option in your touchscreen (or simpler still, an automated telephone line) that allows you to opt into supercharging access for a day, at a price. They’ve already given away free trials of Autopilot, so we already know opening up software for a limited time is possible. Shoot, maybe they can even get some PR out of it. “Free supercharging on your birthday!” or “Merry Christmas, here’s a free day!” These things sound great, but I still have an objection. Tesla needs money to build more chargers. End of story.

This isn’t about paying for what you use, this is about paying for the building of a network. There will always be owners who use far less electricity from Superchargers than their initial cost would have bought in kilowatt hours. There will also always be some owners who use more. Where I live, property taxes are required whether you send kids to public school or not. We’re all paying for a system.

Which is why – and here’s my promised repeat – I don’t think Tesla will ever adopt a pay per use model for Supercharging. They’ll continue their commitment to density and distance, they’ll continue to monitor busy locations and they’ll continue to keep their eye on the prize. Because remember, the hopefully inevitable adoption of sustainable transport means someone, somewhere, will start building a whole lot more electric car charging stations.

Why Tesla Roadster unveiling delay might have nothing to do with it flying

Published

on

Tesla announced on Monday that the Roadster event scheduled for today would be postponed due to the need for it to be held outside.

Less than 24 hours later, CEO Elon Musk broadened that by stating it was due to high winds, immediately sending everyone into a frenzy over the Roadster’s potential ability to fly.

And realistically, it could definitely have to do with it flying, hovering, or hopping; whatever Tesla has in mind for this demonstration could not be impacted by wind. However, it might have nothing to do with the vehicle flying whatsoever, and instead could be a simple precaution, as the Roadster is a very unique vehicle with some already official specs that are just mind-blowing.

Tesla will very, very likely be showcasing both the acceleration rate and potentially even a top speed demo at the event in Waco. Both of these demonstrations, performed with a vehicle that has such incredibly fast metrics, could easily be impacted by wind as well.

Tesla Roadster event requires restricted airspace, and the FAA obliges

Top Speed Demo

At high speeds, aerodynamic forces are already overwhelmingly present. A crosswind or sudden gust adds a layer of sideways force that the tires must counter with slip angle. On a short demo course, that force can shove the car off the intended line, especially in a light car with a low frontal area and little mass to resist the push.

Electric cars, due to their battery packs, have an advantage of an extremely low center of gravity, giving them extra stability. However, the speeds at which the Roadster could travel at the demo could spell some issues if crosswinds are present.

Gusts are worse than a steady wind because the load changes faster than a driver can smoothly correct. That shows up as weaving or a late correction. Headwinds and tailwinds can also spell disaster. Headwinds cut a measured top speed but raise the power needed to get there or maintain it. Meanwhile, a tailwind can inflate the top speed, and downforce issues could become more noticeable.

Wind also loads the body unevenly. A low car can feel light on the upwind side or see a sudden change in downforce if the gust hits a wing or diffuser at an angle. Tire temperature and pressure might stay near a normal level, but lateral grip can be lost as the vehicle is spent fighting the wind.

Acceleration Demo

Launch and 0-60 MPH runs are shorter, so the car spends less time exposed to forces that could cause things to go awry. However, the first second is very sensitive, as a crosswind at launch could yaw the car before speed builds and prior to aerodynamic impact being too great. The driver will be required to correct traction control or manage how much the wheels are spinning, which will likely be corrected automatically by some sort of traction control system within the Roadster (we are fairly certain Tesla will implement something brilliant with it).

These things could cause an unstable run.

A headwind would increase drag as speed rises, while a tailwind would do the opposite. Meanwhile, surface effects, like wind-driven dust, light debris, or even rain, could reduce grip at the exact moment the tires are asked for peak longitudinal force. Standing water plus a crosswind is a common reason an acceleration attempt might be scrapped.

Flying or Not

No matter what Tesla has in store for the Roadster, waiting for ideal conditions is a great idea. People who follow and support the company, along with the engineers involved in the Roadster program, have been waiting nine years since the last unveiling for this moment. Everything should be ideal.

Some speculate that it’s just not ready, and that’s ridiculous. Why would Tesla even schedule the event — albeit prematurely — after nine years if it was not ready? Why would they jump the gun now?

We were all excited for today, but it truly is the most ideal thing in the world to wait two more weeks so everything, including the weather, can be perfect. The delay is simply worth it. But Tesla, seriously, make this the last one.

SpaceX nails “Lucky 13” astronaut launch, leaning into Tesla tradition and superstition

SpaceX launched Crew-13 astronauts to the ISS Thursday, setting up a record fast Dragon docking.

SpaceX launched NASA’s Crew-13 mission to the International Space Station on Thursday morning, getting four astronauts to orbit despite a forecast of thunderstorms and gusty winds that had threatened to push the flight to Friday.

Falcon 9 lifted off from Space Launch Complex 40 at Cape Canaveral Space Force Station at 11:10 a.m. ET carrying Dragon Grace, NASA confirmed. On board are NASA commander Jessica Watkins, NASA pilot Luke Delaney, Canadian Space Agency astronaut Joshua Kutryk and Roscosmos cosmonaut Sergey Teteryatnikov. The first stage booster, B1101, landed at Landing Zone 40 beside the pad on its third flight after previously supporting Crew-12 and a Starlink mission.

It was the first spaceflight for Delaney, Kutryk and Teteryatnikov. Watkins, who flew on Crew-4 in 2022, became the first NASA astronaut to launch aboard a Crew Dragon twice.

Before launch, the crew rode to the pad in Teslas, a tradition on NASA’s SpaceX crew flights since 2020. This time the cars carried specialty plates reading “Lucky 13.” Watkins said the mission patch leans into the number on purpose, as a nod to Apollo 13 and the resilience of that crew.

Grace is now on a short trip to the station. Docking at the forward port of the Harmony module is scheduled for about 7 p.m. ET, roughly 7 hours and 50 minutes after liftoff, which Space.com notes would be the fastest Crew Dragon transit to the ISS yet. Most Dragon flights take around 15 to 24 hours to catch the station. Hatch opening is planned for 8:25 p.m. ET.

The launch came more than two weeks later than originally planned. An oxidizer leak was found in Grace’s propulsion system in August, and NASA and SpaceX added time for tests. That pushed back the return of Crew-12, which has been aboard the station since February and is now set to splash down off Southern California next week. Crew-13 is expected to stay about six months.

SpaceX rescue mission for stranded ISS astronauts nears end — Here’s when they’ll return home

SpaceX already holds NASA orders for crew rotations through Crew-17, while Boeing is preparing an uncrewed Starliner flight to the station as early as December.

Crew-13 was only the first of three SpaceX launches planned for Thursday, as Teslarati previewed on Wednesday. A Falcon 9 launched its Transporter-18 mission from California today, where Google will be launching its first orbital artificial intelligence (AI) test satellite. Meanwhile, Falcon Heavy is set to launch the classified NROL-97 mission for the National Reconnaissance Office from Launch Complex 39A at 11:53 p.m. ET. Its two side boosters will return to Landing Zones 1 and 2, which means Central Florida could hear up to three sonic booms in a single day. The busy stretch follows Starship’s Flight 14 on Monday, which reached orbit for the first time.

Tesla moves forward on Wireless Charging for vehicles

Published

Tesla has moved its Wireless Charging efforts for its electric vehicles forward, as it had a new patent published today, one that it submitted back in March.

The patent describes a system for detecting foreign objects on the wireless charging pad under varying temperatures, aiming to mitigate any undesired results that could come from something being on top of the charging pad.

The abstract of the patent states:

“The present disclosure relates to methods and systems that can reliably detect foreign objects on a wireless charging pad under varying temperatures. In some examples, an object detector can utilize a set of inductive coils included in resonant tanks, and excite the resonant tanks using signals in a range of frequencies including or near a nominal resonant frequency of the resonant tanks. The object detector can detect a metal object based on resistance of a coil increasing and inductance of the coil decreasing. By analyzing the shifts and/or distributions in resonant frequencies and output magnitudes (e.g., output voltage peaks), the object detector can distinguish between changes of frequencies and magnitudes caused by temperature and those caused by foreign objects to accurately detect the foreign objects.”

The object detection system will utilize a set of inductive coils included in resonant tanks, and “excite the resonant tank using signals in a range of frequencies including or near a nominal resonant frequency of the tanks.” Metal can be detected by an increase in the coil’s resistance and a decrease in the coil’s inductance.

By analyzing shifts or disruptions in resonant frequencies and output magnitudes, the system can detect foreign objects. These types of safeguards need to be implemented through the normal operation of the charging pads.

Tesla says its Cybercab wireless charging efficiency is ‘well above 90%’

Tesla plans to utilize wireless charging with Cybercab and Robotaxi-enabled units to help streamline the fully autonomous experience from A to Z. The last thing the company wants to do is have any sort of small obstruction preventing the rider from experiencing Robotaxi as intended.
