Standard Range Plus Supercharging Speed

[Agon]

I don't know why it's only 102kW now, so I'm not sure if it would keep the same 85% of 145kW with an updated charging profile. But probably not as 145kW is stall limitation not a car limit.

I only saw reports of 145kW charging on 2019.7.11, and those were LR cars. Those folks were subsequently updated to higher revs and lost the increased charge profile.

Doesn't the 102 kW suggest a car limitation that would most probably apply to the v2 charging rate as well?

We're talking about two independent capabilities, so I'm not sure I understand your question.

It appears the SR charge profile is limited to 102kW. If that gets increased (as I suspect), it will be done via software update. I don't know when (or if) that will happen.

The V2 Superchargers are currently limited to 120kW for any given stall. (Ignoring Urban Superchargers which are limited to 72kW.) This will be updated to allow 145kW to any given stall. I recall this takes a firmware update that must be done onsite. This has started to happen but it's difficult to determine to what extent.

I can't remember where I read it, but a Model 3 LR, running 2019.7.11, charged at 145kW at the Santa Clarity Supercharger in SoCal. That site is listed as having a 120kW capability so we can't yet use the navigation system or Tesla's online Supercharger map to determine if the Supercharger is an updated V2 site. (We should probably call these V2+ sites or something...)

It appears the current SR cars would all charge the same on V2, V2+ and V3 sites and be limited to 102kW.

Thanks Zoomit.
I was just wondering if the information that the SR+ is capped at 102 kW didn't make you doubt your own model for SR+ charging at v2 chargers. But I gather from your last post that you now seem to have left your model?

But I dont understand why you now assume the SR+ to be kept at 102 kW when the charging power is increased for the LR - instead of assuming a constant "c-rate" implying that the relationship between the charge rates for the LR and the SR+ be kept constant at 85%, which would put the same level of stress on the SR+ compared to the LR as now (as I understand your argument)? (= approximately 125 kW at v2+ and 212 kW at v3).

These are the very first Tesla vehicles with the new battery chemistry in a smaller kWh pack, maybe Tesla is waiting to collect some usage data first at ~102 kW before increasing it.

My models assume the SR has an updated charging profile, with a similar, but ratioed, capability as LR.

Do not pay any attention to the 85% ratio. The current SR would be car limited at 102, while the LR is stall limited at 120kw. 85% means nothing.

That one video clip does not have me convinced that it’s limited to 102 kW. We need more data points.

Show us what you can do, SR+ owners.

 

[Leafdriver333]

LR is much more expensive for several reasons than just extra batteries, I guess.

But doesn't your prior argument about c-rate imply that the SR+ would at least charge at roughly 67% of the LR when the charging power goes up? Why do you now suggest that SR+ stays at 102 kW?

I have seen several reports about 102 kW being the limit already. Unfortunately.

Here's some data from my first road trip today.. left Fresno area at 240miles/100% and made it to Mojave around 7% then charged at the Supercharger.

Thanks. Another data point to confirm the charge rate capped at 102 kW. Quick question. What was the total travel distance from Fresno to Mojave (that consumed 93% battery). Also, how long did it take to charge from 7% to 90%?

 

[Ajlepore]

It was 180 miles and arrived with 20miles left (took 220mi of range) so closer to 8%.
Went from 20miles (1053am) to 191miles (1128am) So 35min for 171miles/71.25% increased to a total range of 191mi or 79.58%.

What new battery chemistry?

 

[willow_hiller]

What new battery chemistry?

Maybe "new" was the wrong term. I was under the impression that the Model 3 has different cells compared to the S and X, ala Tesla releases rare details about Model 3’s battery cells, claims highest energy density and less cobalt

Yes, I expect SR and LR batteries to eventually charge at same c-rate. I am not suggesting SR stays at 102kW. It appears that’s the current limit however. I don’t know when that will be increased but it seems likely it would be in conjunction with the increase for LR batteries to support V3 Supercharging.

I did a 10-80% SC log from my SR+ (ambient temp @ 10 deg C) last Sunday (that was on 8.4). Here's a trending of it:

 

[ab26]

What’s the difference between the yellow and the white curve? What does power limit mean?

 

[Gen3]

So you maxed at 120 KW, momentary peak above. What software version are you on?

 

[ab26]

I think we should be looking at the white curve. So max is still around 102Kw

You’re right. What is the theoretical limit based on ?
