Another Tesla P85D compilation that very well defines what the EV Grin looks like on most people!

Just curious, but how do those pictures relate to the cells being BE's ?

BE's are the only cell in existence with that characteristic triangle top.
The only debate we had was if they were BD's or BE's
I can say with 99.99% certainty they are regular old BE's just like they started using in early 2013.
The fuse wires are also the same diameter.

So , if it's not the triangle top, how exactly have you confirmed these 85D cells are BE's ?
...and not some other Tesla special ?

...how can triangle top be confirmation if PD also has them ?riba2233 said:

It has been hinted that Tesla uses proprietary cells, modified to suit their particular requirements, that are not available to other customers. So, potentially they could have modified BEs or some other cell incorporating the triangular top (or other features) found on the BE. Or they could indeed be regular, unmodified, BEs the same as you can buy on the open market.

Lol. Round and round we go. I see no benefit in expending further energy arguing here.

Pfft ..... my v10 audi r8 will smoke that tessla in whatever insane mode its got .....meet me at the track sucka. No wonder top gear hates the Tesla.

Because cells okashira removed from tesla pack has O ring on cell negative, just like BE's. Just look at his sales thread.
Also, it's not modified or anything because dicharge graphs are the same.
That's it from me also
@green machine: I hope you are just trolling badly
Tesla weights 2.2 tones and costs less and doesn't consume gas so it costs even less long term, and it still beats cars like BMW M5 on acceleration, and it's close on performance with cars that are made for that purpose only, while Tesla S is luxury sedan, and not a super sports coupe.

I had the pleasure of a test drive in a P85D (driving myself) and i have to give it to Tesla, it is a deeply impressive machine on many levels. If i had the money, it would definitely be my number 1 choice for my next car (well P90D actually). Unfortunately, it is a bit rich for me right now, but hopefully some time in the future, it will be mine
I used to have a very fast ICE car and used to ride a crotch rocket, even did a few track days on sports bikes, so I know what fast is. Off the line, and up to maybe 80 or 100mph, there is very little that could keep up with it, or even get close to a P85D or P90D on full afterburner... There are real G's when you plant that throttle from zero. I think i had the very pleasant Chinese sales lady that brought me out, slightly concerned when i kept the boot in a bit long...lol
I see quite a few Tesla in Shanghai now, and they have a big store with supercharger etc, not too far from me. I have so much respect for Tesla and Elon Musk of course. Hats off to them. Innovation, hard work and no BS, what is not to respect?

Im sure okashira is correct that they are the BE cells, I just don't understand why he insists the triangle cap is any proof..when other cells have similar caps ?...so the base is the proof...but no pic.
Also having looked through the sales thread (again) there is no clear pic of the base of these cells there either....unless I missed it ?
However, having now proven these are BE cells, doesn't that mean they are the lower rated 3 amp continuous discharge cell ?......compared to the 10 amp rated BD .? ( long thread on that previously )

For anyone wondering what we are referring to with the "O ring". On the base. ( technically it's a circular indent crease)...
This is the BE (green) cell with the BD beside it, showing the difference.

For what it's worth, I'd be very surprised if Tesla would use a standard off the shelf cell in their cars (and i don't understand why it is so important to know). Tesla have the buying power to have custom cells produced and I don't doubt they have the technical expertise/resources to play with the chemistry to tweak them to best suit their application/requirements.
Samsung offer an EV specific 18650 cell for example, which is only available to companies involved in EVs, they will not supply it otherwise. So what makes anyone think they can buy Tesla cells, from some guy off Ebay or Aliexpress? Making some inferences that the cell must be this, or that, because of some mechanical part of the cell, or the appearance, could be well founded. But it could also be completely wrong, and in my humble opinion, the latter is more likely to be the case.
Comparative performance tests between new Tesla cells and some standard (A grade) Panasonic cells, might provide some insight as to what Tesla use, but even then, it would be inconclusive and the tests would have to be very extensive to be even slightly sure of of your findings. Sorry guys, i really think this is a fruitless exercise

Tesla were widely reported to have signed a deal with Panasonic a year or so back , for some 2billion cells over the coming years.
A supplier would not sign such a large volume deal if it entailed frequent changes to the chemistry or other specs. It would be just too risky on a high volume, JIT, price controlled, quality critical , contract.
So , yes I am not surprised that they are using the same cells as a year or so back, and I wouldn't be surprised that it is something that Pana' now retail as a " standard". Cell.
Remember this BE is not the most powerful cell they produce.

If you're buying 2 billion of anything it's likely to be customised to your spec in some way. Be that a 10 year calendar life, an extra amp discharge capability or tighter tolerances on the spec. Would Panasonic then sell that cell on the open market? Depends on who has the most leverage: Panasonic would want to sell them, Tesla would want exclusivity.

That would depend on the contract terms.
...and Tesla seem to project an "open technology" philosophy .?
