If you fast charge, Tesla will permanently throttle charging

[Redmiata98]

Rking, is that 72 “limit” based on the max power listing on the touchscreen icon for that location? If not, what is your reference?

Urban superchargers.

My 90 just crossed 20k and it still Supercharges at 120kW for about the same amount of time. It's not something I can directly compare because the temperature seems to change how long it holds high rates.

11/2017 100D, 28k miles, set a new charging record for herself, 125 kW. I've never tried to limit at a (DC) supercharger, but have only seen at AC sources.

You can only limit charge rate during AC charging. DC charging is as fast as the charger can provide, you can't adjust any settings.

My P85DL just crossed 88K miles and still starts out charging at 118KW.

It's just the 90 packs and some 75s made at the same time.

 

[Naonak]

Any pack with a silicon anode, unfortunately.

PS - I can't believe this thread is 2 years old now... wow.

So which ones have a silicon anode?

 

[Lanber]

When Tesla updated the chemistry and introduced the 90 and 75 packs.

Those fore sure are subject to throttling. I dont know about the 100 packs or the Model 3 packs.

90's. Potentially the 100's but the 100 pack has a tweaked chemistry compared to the 90's. (which itself was a major tweak from the incredibly bulletproof 85's.)

Makes me wonder why they decided to discontinue the 85's.. maybe they were more expensive to make?

The 85's were just tanks. They were a new company, so they overbuilt the hell out of them to be sure customers had the best experience. As time went on and they learned more and more about real world useage, real world charging data etc etc they started tweaking. The 90's were the first dramatic change in packs, and it wasn't perfect but didn't have catastrophic failures so.... Learned from those, and now we have a pretty rock solid 100 pack based on experience.

yup, pretty happy with my S85

Well, the change to the chemistry with adding extra silicon gave a little bit more energy storage capacity for the same number and size of cells. So they probably thought it was going to be an improvement and the next step forward. Perhaps they did not quite anticipate the downside that would show up.

 

[Simon21]

So how can I figure out if I can charge my 100 cells with chademo? It's closer and cheaper than supercharger for me

You don't need to figure out anything. You definitely can; just buy the adapter.

First, the 100 packs are not affected, and:
Second, all of this discussion has nothing to do with "can you" or "can't you". It is just that a couple of specific battery types could have their maximum charging speeds reduced some, but they would still work.

 

[Fiver]

First, the 100 packs are not affected

While all signs point towards this, in fact we do not know for sure yet about the 100 packs. Just because it hasn't happened yet doesn't mean it can't happen down the road.

A better way to phrase this would be "As far as we know, only 90 packs are affected so far."

You know, everyone always says that, "it has extra silicon". But if you track back that quote, it all stems from a single half hearted, unsure, response from EM on an investor conference call. Literally a one liner if that. Yet we have zero evidence to backup that claim. So I've always wondered if the cells really are different in that way or if it's something else entirely.

Really? That's interesting, if so... but that then raises the question as to why only the 90 packs (and the associated 75 packs) are affected so drastically compared to the 85s and presumably the 100s?
