There are thousands of Teslas sold worldwide. And there is almost zero hq videos or photos of its teardowns. Why? Is it because of patents or something? I only found some old, low quality videos or photos without focus... I think it would be very interesting to see how this very complicated system is made. Look up part's datasheets etc. From simple keyfob electronics, through display driver to motor inverter.
Maybe if some of you are interested in this too,maybe we can share links in this thread to various photos and videos revealing Tesla's inside which you found on the internet or make one if you can and discuss about them?
I don't know if its against Tesla's patents or some laws, if it is, we will have to close this topic, if not I think it's great idea. 8)

There is a lot on YouTube if you search for Tesla teardown, for instance battery pack, motor and yes even the keyfob you mention:

Videos like this weren't what i mean. I watched it before. It's not technical, you can't really see the board with details, read part numbers etc. Photos, hq ones would have been more valuable than this. They aren't that easy to find.

I think that Tesla have made most if not all their patents public and free for any one to use.

I expect the reason is, most owners would prefer to keep their warranty program rather than void it by hacking things to bits.
And you are looking for the double subset of people who 1) have the money to throw away that much value; 2) are technically inclined enough to take obsessively detailed photos of the innermost workings. These people are few and far between.

I never cease to be amazed how many people fail to understand the fundamental nature of patents, namely that you openly publish the details of your invention (in your patent) in return for legal exclusivity on exploiting the ideas therein. By definition, if something is patented it is openly published. So there is no possibility of it not being public (excepting of the rare occasion where a government steps in and classifies/makes secret a patent between the application and formal issue).
"Free for any one to use" is a different issue, and in this Tesla is an unusual case.

Patents are public unless it's classified.

Is there such a thing as a 'classified' patent???

Yes, in the UK it's known as a patent secrecy order.
We can't know what has been classified, but you can have a good guess: novel radar techniques (anti-jamming etc.), methods for undetectably intercepting communications, methods for detecting communications interception, anything conceivably of use in nuclear weapons, chemicals that could be used as weapons (e.g novel nerve agents), methods for unfailingly detecting when civil servants, politicians and policemen are lying, and so on.

Now we know you're just yanking our chains.
Prior art has been shown in that field for years.

Yes, but to be patentable the method must also be 'not obvious', and "their lips are moving" fails that test.

Its all about money, the investment return by showing it publicly, like a complete technical teardown and etc into the net/public is not enough to cover the loss by voiding the warranty.
Look at how people smashed a new released high end cell phone just to generate view counts.
But I guess its done already while ago by Tesla's competitors for corporate R&D, of course, not for public consumption.

Thanks Cerebus, just been reading around the subject.
So the Patent Secrecy Order (known as a Section 22) actually stops the patent being granted, but will allow you to take it just upto the wire, so if the PSO is lifted it can then be granted & published.

So I was listening to James Dyson on Radio4 this morning saying that Dyson file over a 1000 patents a year, apparently more than anyone else, yet on pages 5&6 Dyson rank 9th in 2012 with a mere 66 patents. Interesting to think that they might have increased their 'output' by that much in such a short space of time, or perhaps he includes other territories in that figure. He was also hinting at a breakthrough in battery technology.

Some years back I was surprised to see an industrial unit with cyclone dust separators. Apparently this tech has existed for over a hundred years, so how Dyson got a patent for it is a mystery. The patent might have related to its use in a domestic cleaner, but isn't that a case of an 'obvious use' for an existing idea rather than an actual invention?

They may well apply for 1000 patents a year - in reality only 66 of them are either worth pursuing or come back as original and hence get granted.
