P90D Supercharging Data

[Oyvind.H]

So it takes 6% longer to get about 6.4% more range.. or am I missing your point?

If 16-90% takes 52 min with 85 and 64 min with 90 then it takes about 23% longer to charge. In return you get 6% more energy (according to Tesla).
And if the 90 pack is only 3-4kWh bigger than the 85 pack, then it takes 23% longer to get 4-5% more range.

Just because a pack has more capacity does not mean it should take longer to SpC. The 85 kWh actually charges much faster than the 60 kWh.

But with the 90kWh pack this seems to be the case. I would have expected the opposite - higher average charging power, when in reality the 90kWh seems to taper much quicker. Disappointing.

Correction: with new software the 90D supercharger speed has increased a lot.

From 75-80kW @45% soc to 105kW @45%.

Now it charges as expected

What is this you say?

Or you got the new 90 pack... and all the old 90 owners are bag holders.

 

[apacheguy]

Hah! Is this the whole A pack debacle all over again?

Don't think so. My pack charged slower than 85 packs earlier. With software update it now charges way faster than 85 packs. Both in time and energy.

Can you tell me what the difference is? Some number so I can get an idea. For example, how much power do you get at 30% or at 50% or at 80%. I have a 2 year old 85 and it would be interesting to see how much of an improvement the 90 battery is.

 

[apacheguy]

Could be possible they updated the taper algo and all cars. Anyone with an 85 checked?

I watched that video and it seems while it is a little faster, I wouldn't use the words 'way faster'. More an incremental improvement. It would also be interesting to test the 85 again after the new software. I think Bjorn took the old 85 data from some time ago. It could be possible that the new software also helps with the 86 battery.

I`ve recorded charging power for about three years. Because of the introduction of % instead of km/miles to measure capacity, my old numbers are in range, not percent.
In other words it`s hard to be precise.

But what I can say is that my 2013 S85 had its highest supercharger-speed when it was new.
Back i 2013-beginning of 2014 it had about 95kW @45% (@about 166,5tkm range)
In 2015 it was down to about 85kW @45%.
Some probably because of sw updates, and some due to degradation/capacity loss/higher internal resistance.

With my new 2016 90D I previously got 75kW @45%
Now I get 105kW @45%.

I think Bjørn has compared 85 with new software to older software and found no increase like the 90 got. However - his numbers are not the same as mine. He seems to get a bit lower power than me at low SOC, and he got a dip that I didn`t see when I tested. But I`m going to visit several superchargers the next week so I`ll know more then

All in all, maybe not "way faster". But definitively faster

@Oyvind.H - On which firmware specifically did you notice the speed bump?

 

[Oyvind.H]

It believe it was the old speed with 2.17.37. Tested 11th of June.

And new speed with 2.24.86. Tested 29th of June.

That's the only two data points i have with and without speed update. So it's somewhere in between

Thanks for the info, that's very interesting. It matches my experience. Supercharging has definitely become slower for me as well. Mine is a 2014 s85 with 82k miles. If lucky I get 77 kW at 45%. That's it. I just finished a 4400 miles road trip and had plenty of opportunity to watch Supercharging. Several times it was slower than normal (not being paired). And those times it was normal speed it just isn't as fast as it used to be.

Back in May, after a leg of a trip I pulled into a Supercharger and began to video tape my charging progress.
Sadly that video is gone, however I did watch the video and transcribe the data into a spreadsheet for future analysis.
I was on firmware 2.18.77 at the time and the external air temperature was 63F.
The S was warm due to a 110+ mile highway run.
The Supercharger was in Auburn, MASS and of the 8 stalls I was the only one there...
Oh ya.... my S is called The Silver Surfer (Marvel Comics Character from the Fantastic Four).
The minutes show the elapsed minutes of the charge session.
About 1/4 of the way into the supercharge I heard the fans turn on which was something I had
not experienced before. This was my first supercharger charge btw.

Here is the data...

 

[Oyvind.H]

Another test today
112kW @47% soc.

 

[apacheguy]

Those are rates I certainly have never seen before. I'm on 2.20.x at the moment.

Did you just plug in at 47%? I noticed when I plug in at a Supercharger the charge rate is very high for a moment and then it adjusts down quickly.
