How Tesla Challenges Other Car Makers

Tesla challenges other car makers to build better cars says Diarmuid O’Connell, Telsa’s vice president of business development at an industry conference.

Diarmuid O’Connell, Tesla’s VP of business development, had harsh words for competitors last week at the CAR management briefing seminars in Michigan. He told the group that Tesla challenges other car makers to build better cars.

“You can split the market of EVs into two programs,” he said. “Many are compliance programs. Exceptions are Nissan, ourselves and BMW. Most are focused on minimum compliance, lowest common denominator behavior, and the vehicles reflect that. In some respect, they are appliances, in terms of the way they look.”

CARB And The EPA

His remarks come at a time when two important regulatory programs are up for review. The California Air Resources Board is taking a look at its zero emissions vehicle policies and the Environmental Protection Agency is considering changes to its CAFE standards.

Traditional car makers are trying to get both agencies to relax those standards, but O’Connell says they should stop trying to “slow walk” the rate of progress toward a emissions free future and get busy building better cars. He says his company wants California and the EPA to raise their standards, not relax them.

“From an empirical standpoint, the [regulations] are very weak, eminently achievable and the only thing missing is the will to put compelling products on the road,” he said, according to The Wall Street Journal.

This week, Mary Nichols, CARB chairwoman since 2007, announced that she isn’t satisfied with having just a few electric cars on California roads. The current standard calls for 2.7% of all cars sold in California to be electric. Nichols wants to set the bar higher. In fact, she would like it if all the cars sold in California were electric by 2030.

For its part, the automotive industry is busy telling the EPA that the current CAFE standards are too high. Any further tightening would be bad for business. “We need consumers to buy them in high volumes to meet the steep climb in fuel economy standards ahead,” the Alliance of Automobile Manufacturers, an industry lobbying group, told the conference. The implication is that higher standards will kill the automotive business, cause massive layoffs, and have a negative impact on the economy.

This is precisely the same argument the automobile industry made about safety related changes in the ’50’s, seat belts in the 60’s, exhaust emission in the 70’s, airbags in the 90’s and better crash test performance at the beginning of the 21st century. Its complaints today are just more of the same.

CAFE Olay

The furor over EPA standards is actually a tempest in a teapot. On the surface of it, the 54.5 mpg requirement by 2025 seems like a huge increase above present day performance. But in reality, that standard is based on the old EPA mileage testing protocol, which was amended several years ago because it resulted in numbers that were wildly optimistic.

When the EPA adopted a new standard designed to better reflect real world expectations, it did not apply the new standard to the computation of the 2025 goal. If it did, that 54.5 mpg number would convert to around 37 mpg — which many of today’s cars are already capable of achieving.

To suggest that car companies cannot achieve a CAFE of 37 mpg using the current EPA protocol is patently absurd. In fact, a representative of Johnson Controls, one of the largest suppliers of components to the automobile manufacturing , said last year that car makers can easily meet the new standard and, in fact, many are already doing so today with internal combustion cars.

Charging Technology

One area where other manufacturers need to step up involves recharging technology for EVs and plug-in cars. At present, the best any of those other cars can handle is 50 kW. Tesla already has Superchargers with more than double that capacity. It’s new liquid cooled charging cables indicate the company has even higher power chargers in mind for the future.

O’Connell told the conference that drivers of competitors’ cars would be welcome to use the Supercharger network if only their cars were capable of handling the higher current. Tesla made its Supercharger patents public last year, but no other manufacturer has expressed any interest in them. Instead, the industry seems content to live with 50 kW “fast chargers” that really aren’t all that fast.

The Week In Review

Tesla has had a rough week. The stock market was disappointed with what Elon Musk had to say during the 2nd quarter conference call and punished the company’s stock, which closed down nearly 9% for the week.

The real question on people’s minds is whether Tesla will bring electric cars to the masses the way the Model T put the world on wheels almost a century ago, or whether it is a company that caters only to the wealthy and will flame out the way the Concorde SST did? If you are reading this, chances are we know how you would answer that question.

"I write about technology and the coming zero emissions revolution."

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

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.
