Tesla emphasizes factory safety, preempts possible smear campaign by auto union

Published

on

Tesla released a blog post Sunday evening that reemphasizes the company’s goal to become the safest auto factory in the world. The post comes after the United Auto Workers Union (UAW) attempted to rally support earlier this year from Fremont factory workers in favor of unionizing.

Tesla states that it has received several media inquiries over allegations about safety at its Fremont, California factory. The well-timed nature of the inquiries, and similarity in topic, led Tesla to believe that the UAW was spreading anti-Tesla propaganda to the media in an attempt to provoke a response from the public, and from Tesla employees. In typical fashion, Tesla acted quickly and took to the offensive to defend the company’s approach to manufacturing, and maintaining the health and safety of its employees. The company has gone as far as forming dedicated Ergonomics Teams that have exclusive focus on “improving health and safety and reducing ergonomic risk for current and future production”.

“We are building entirely new vehicles from the ground up, using entirely new technology, production, and manufacturing methods, and ramping them at high volume. Getting this right is extremely difficult, and we deeply appreciate the hard work that all our employees do to help us achieve what most regard as impossible.” says Tesla through its blog post.

Tesla notes that in just 15 years, the company has become the largest manufacturing employer in California with over 10,000 production jobs in the Fremont factory and surrounding Bay Area.

Tesla has a proven track record of putting safety first as made evident by the award-winning safety ratings for its Model S and Model X. Vehicles have taken the brunt of the impact for their occupants, have swerved to avoid accidents and have even accelerated to avoid accidents. The innovative safety features Tesla has built into its vehicles is unsurpassed in the automotive world.

Though Tesla’s safety record to date is already better than industry-average, according to its press release, the company indicates that it continues to learn and apply new production processes aimed at improving employee well-being. Among the improvements are:

  • Added 3rd shift to the manufacturing schedule to cut overtime because the employees asked for it and it was the right thing to do.
  • Hired dedicated Ergonomist and established an Ergonomics team to ensure that current and future Tesla manufacturing lines are ergonomically friendly for employees.
  • Model 3 has been designed with manufacturing employee ergonomics in mind. The Tesla Ergonomics Team works closely with design and engineering teams to catch ergonomics issues before they happen and proactively drive these improvements back into the design of the equipment and the car. Yes, you heard that right. Tesla will redesign the car if it is resulting in ergonomically challenging situations for its manufacturing employees.
  • Established safety teams in every department which meets regularly to ensure safety is a top focus in its manufacturing operating departments.

These changes are not just skin deep and the company is seeing the results of the changes already. Tesla says it has collectively reduced 52% in lost time incidents and a 30% reduction in recordable incidents in the first quarter of 2017 versus the same period last year. These more granular metrics support an improvement in the industry standard Total Recordable Incident Rate (TRIR) which at the end of Q1 2017 was 4.6, a full 32% better than the industry standard of 6.7.

Anyone who has worked in an industry where safety is important can tell you that a culture of safety awareness is built day by day, month by month over many years. Tesla has a demonstrated history of superior results. The steps it has outlined to drive further improvements at the factory are evidence of a continued focus on safety and its employees.

The full post from the Tesla Blog reads as follows:

Creating the Safest Car Factory in the World

Earlier this year, the United Automobile Workers (UAW) announced it was attempting to organize workers in Tesla’s Fremont factory. The latest phase of their campaign involves a concerted and professional media push intended to raise questions about safety at Tesla.

We have received calls from multiple journalists at different publications, all around the same time, with similar allegations from seemingly similar sources about safety in the Tesla factory. Safety is an issue the UAW frequently raises in campaigns it runs against companies, and a topic its organizers have been promoting on social media about Tesla.

Some of the publications who have contacted us have rejected covering this “story” because they understand it is a misleading narrative based on anecdotes, not facts. However, there will likely be a few publications that choose to publish stories regardless, so we want to make sure the public also has the facts. Watch for these articles to downplay or ignore our actual 2017 safety data and to instead focus on a small number of complaints and anecdotes that are not representative of what is actually occurring in our factory of over 10,000 workers.

First, some context is important. The difficulty of starting a successful U.S. car company cannot be overstated, as evidenced by the fact that Ford is the only other U.S. car company to have never gone bankrupt. We are attempting to break this trend in order to fulfill our mission of accelerating the world’s transition to sustainable energy.

We are building entirely new vehicles from the ground up, using entirely new technology, production, and manufacturing methods, and ramping them at high volume. Getting this right is extremely difficult, and we deeply appreciate the hard work that all our employees do to help us achieve what most regard as impossible. While we still have a long way to go, in less than 15 years, we have become California’s largest manufacturing employer, creating more than 10,000 high-quality production jobs in the Bay Area, many of which had previously disappeared with the closure of NUMMI under the stewardship of the UAW.

As we work to achieve our mission, nothing is more important to us than protecting the health and safety of our employees. As we look at our safety record in prior years, we realize that we have not been perfect. No car factory is perfect, but particularly given that Model S and X were the first cars we built at more than tiny volumes, we fully acknowledge that they were not designed for ease of manufacturing – far from it. As would be expected, we have since learned many lessons, including how to improve the production process for the well-being of our colleagues.

Here are just some of the improvements that we have made:

  • Historically, depending on production needs, some Tesla employees have worked significant amounts of overtime because it was necessary for the company to survive. However, working overtime can be challenging for employees and their families. Last year, we added a third shift to reduce the overtime burden on each team member and to improve safety. We did this because our employees asked for it, and because it was the right thing to do.
  • As a result of this change, the average amount of hours worked by production team members has dropped to about 42 hours per week, and the level of overtime decreased by more than 60%. We hired our first dedicated Ergonomist in 2013, and in 2015 established an Ergonomics Team exclusively focused on improving health and safety and reducing ergonomic risk for current and future production.
  • In addition to improving the process of building Model S and X, Model 3 has been designed specifically with ergonomics in mind. Our ergonomics team has worked hand-in-hand with our engineers on the design process. As just one example, we created simulations that showed us where reaching or bending by employees was most likely to occur, which in turn allowed us to redesign the equipment and the car to eliminate these issues as much as possible.
  • Each department now has a Safety Team that meets regularly to increase safety awareness and recommend improvements, many of which have already been implemented.
  • We are continuing to establish health and safety management procedures to scale with our operational growth.

The third shift, ergonomic improvements and increased safety awareness have collectively led to a 52% reduction in lost time incidents and a 30% reduction in recordable incidents from the first quarter of 2016 to the first quarter of 2017. In addition, through the end of Q1 2017, the factory’s total recordable incident rate (TRIR), the leading metric for workplace safety, is 4.6, which is 32% better than the industry average of 6.7. This data shows that there has been a dramatic improvement in employee safety, we are now significantly better than industry-average, and we continue to improve each day. A few anecdotes in a factory of over 10,000 people can always be given, but these are the facts.

Tesla’s safety record is much better than industry average, but it is not enough. Our goal is to have as close to zero injuries as humanly possible and to become the safest factory in the auto industry. We will get there by continuing to ask our employees to raise safety concerns and to keep proposing ideas that make things even better.

The alternative is to stop improving and to instead do what the rest of the industry, including the UAW, has always done. But being industry average would make our safety 32% worse. We care too much about our team to go backwards.

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

Credit: Tesla | X

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.
