Yeah right, different story  in the Mining industry, if your a contractor, get injured and report you will be blackballed from every site.

 

Auto quite different. There's good and bad but some of the majors take it super seriously... as they should.

do a google on nummi and fremont, youtube has some excellent videos (quite short but informative). not to be underestimated the challenges of a facility of its type. I was personally trained by some of the guys from that plant.

 

Bit different now - how many cars/year in the last iteration? Something like 500k? Reasons for it but I imagine it was a super busy place with suppliers etc back when you'd worked with it, would have been quite a thing to behold.

Not an exhaustive scientific study by early evidence suggests good battery life for modern EVs with sophisticated battery management

Quote

Tesla Batteries Last Forever (Basically)

New data suggests Tesla batteries last up to 25 years. In this episode, we’ll be diving into this data and seeing how it translates to owners.

Back in April, I shared data on Tesla battery degradation. Since then, Tesla owners have been measuring and sharing their battery degradation data – and the results have been surprising. Tesla owners who contributed to this data first drained their EV batteries down to 0%, then charged fully them to 100%. This is to get a consistent measurement on how much energy a battery can hold.

Despite the data, many people wonder why lithium-ion batteries in phones and laptops can barely hold a charge after a few years, while lithium-ion EV batteries don’t suffer the same fate. Well, according to lithium-ion battery cells studies, after 500-800 charging cycles and 100,000 to 150.000 miles a battery’s charging capacity drops to around 70%. However, most EV owners don’t typical drain their batteries to 0% or 100%. This increases the battery life significantly. Based on study estimates, owners who practice partial charging generally see degradation after 1,200-1,500 charging cycles and 350,000 miles of life.

Because study data on EV battery life is limited, the data provided by real owners, as mentioned above, is much more valuable. It is important to note, charging habits are not the only contribution factors to battery life as factors like temperature and usage patterns also play a role.

As stated, most owners don’t typically run their batteries to 0%, and by default a Tesla battery stops charging at 80%. This is to reduce battery strain.To even further reduce battery strain, Tesla may limit Fast Charging speeds. All of these factors combined are Tesla’s safeguard to help protect your vehicle, ensure you have a great experience with your luxury EV as well as allow for an expansive lifespan (unlike phone and laptop batteries).

In running some regression analysis on the user-provide data, I found that there was some high volatility. This is likely due to the factor that the data is user-reported, and it is not being measured in a controlled environment.

When Eindhoven University of Technology Systems and Control Professor, Maarten Steinbuch, looked at this data, he found that “on average the batteries have 92% remaining at 240.000 km. If the linear behavior would continue, then the ‘lifetime’ (still 80% capacity left) can be calculated as follows: 92-80 = 12% times 45,000 km = 540,000 km.”

I also looked at another studied from YouTuber and battery aficionado Jehu Garcia. He tested some early Tesla batteries and found that without use, batteries degraded at about .35% per year. Which means, after about 285 years, these batteries will be almost completely dead.

Working with the figure that batteries will retain more than 80% of their capacities for up 310,000 miles and considering that the average US drives about 13,5000 miles, on average, a Tesla battery does not need replacing for around 23 years. This is:

15 more years after the battery warranty runs out

13 years after cars become fully autonomous

4 years after my son can legally drink

and 10 years after the robots take over our world and enslave humanity

Okay, that last one might come sooner, we’ll see…

The point is, by the time your Tesla battery wears out, we’ll be in a totally new world - and likely won’t even be driving ourselves anymore. In fact, Elon Musk recently stated that he thinks in 20 years we won’t even have steering wheels in cars.

So, when it comes to the lifespan of your Tesla battery, rest easy. It will likely outlast the rest of your car.

I compiled my data using the following sources:

Yeah... nah

 

Read the comments on that original post, some of which come from people that actually assemble packs - calendar ageing, knee characteristics and the like are all real things.

 

Most EV manufacturers (particularly if with active cooling) will list fairly draconian numbers for expected life, and the rest is cream. The article cited is very misleading, however.

Brisbane Tesla dealership and supercharger opened yesterday with the Lord Mayor cutting a ribbon.  I hope it was recycled ribbon.

They can reuse it when they open an Adelaide store

If they're going to go to that amount of effort, why wouldn't you deal with that rear quarter window?

I don’t think "how do we make it tasteful?" Was the question at the forefront of their minds 😳

Bingo.

There are only two in existence and both are in Norway. The rebuild took place in the Netherlands and for this particular vehicle, which was the first, took two years. There are also two Model S rebuilds used for the same purpose in Germany however they are a different design. Supposedly, they are a popular choice...

I thought you were going to say “ Another Tesla driver sleeping on autopilot”.

 

With a compact coffin I should fit in the back of a Model 3. It is 1.9m internally with the rear seats folded.  I’m not fat so the lack of hatch should be ok.  Alternately I could fit in any scale-electric if cremated.

 

Better still, funeral drone charged from solar panels.  Propellers could dust you over a favourite fishing spot or wilderness location. Two thumbs up emoji.

 

 

These ideas are too good to waste.  I am starting an eco-funeral business.
