85kW battery charge data

[airborne spoon]

I am looking for anyone that has any supercharging data for a 85kW battery. I have over 100 data points on my graph but they are all after Tesla nerfed the supercharging speeds.

I am looking for the battery % and current kW but it needs to be before the speed reduction by Tesla.

You can see the graph has a general trend line and the few red points are my outliers that cause concerns.

Basically I need to have some proof that the speed was cut by a crazy amount when Tesla started sending out the 85kW updates.

For a point of reference before the speed nerfing when my battery was at 50% charge I would pull 70-72kW. Now after all this I'm around 48kW at 50% and this has caused an extra 15 min average wait time to my supercharging while traveling.

They throttled me back to 60kw maximum with v10. I joined the class action suit in SF. Before that I was hitting close to 100kw. They killed my battery pack. If u look at my battery on chart, see where it drives when v10 was installed.
I have text from Tesla saying there is no guarantee of charging rate. I have to upload it. My theory is, they r trying to extend battery life to get us out of warranty and change $20k for new pack. BUT, dont make 85 anymore so we get 90 or 100.

 

[Lasttoy]

I found it. Here is the official word from Tesla , no guarantee on charge rate.

You talking about an 85 kWh battery?

kWh is the correct unit for battery capacity and energy. kW is the correct unit for power and charging rate.

This was my 85kW battery rates around May 25, 2019. Pics below are at 10% increments, starting at 20% and ending at 90%. Needless to say are not the same today...

I'm in the same boat as everyone else. I made 2 identical 800 mile trips to Florida one before and one after. After added 4 hours each way to my trip.

 

[r1200gs4ok]

all started at 2019.40.50.7 for me and got worse at 2020.8.1.......my battery has degraded from 98% at 15 miles new to 95.8% at 2149 miles 2 months old to the day

My 85D battery supercharged very similarly to @BlueOvalFan 's pics, above, (or better) until throttled, some time late 2019. If I bring to an SuC now at 20%, I'l get 85 KW for the first 10% or so, but it will drop to 55 KW by 40%, and 45 KW by 50%.

I drive frequently to both Ottawa and Montreal from N/W of Toronto, a 350 mile trip. What used to be a 20-25 minute charge at the half-way point, now takes 60 minutes - or requires 2 stops at 35-40 minutes. The last trip I made was cold and snowy, so it took 2 stops of 60+ minutes each. I would have stopped twice anyways, but it would have been 20 minutes each, previously. Turns a 5 1/2 hour trip into a 7 1/2 hour trip

So I took our ice car on the next trip. My wife was much happier.......
No more long trips in my 85D. The car is in great shape, drives beautifully, and has had minimal issues in 5 years. I was thinking of keeping it for another 3-4 years, but I think I'll sell it this summer. I'm not happy

Yeah my 2014 S85 128,000 miles chargers about the same also

That’s a smart idea!

I'm still on V8 and I pull 74KW at 50% with 115K miles vs 80KW at 50% when it was brand new.

I expect that when I'm forced on to v10 my charging rate will drop dramatically as well as power curve.

I'm contemplating just living without connectivity and leaving it on v8.

P85DL here, i rarely supercharge

i did just before 2019.16

13%: 119kw
30%: 107kw
43%: 78kw
50%: 75kw
62%: 58kw
82%: 39kw
90%: 31kw

Supercharged few weeks ago for the first time since:

6%: 127kw
11%: 100kw
27%: 76kw
50%: 58kw

Mine are pretty close still currently, within 10 kw for most. However I never updated and still on P85 2018.50. Maybe 60-70k miles on this battery. I supercharge a lot. I will verify against your numbers next time.

Actually I noted a recent session at a 250kw charger to test...

5% 135
10% 119
16% 108
20% 102
30% 88
43% 71
51% 60
87% 30

Here is what I got back in February on a road trip in my 2015 85D (battery warm from driving 1.5-3 hrs):
10% 113
15% 96
20% 88
25% 82
30% 76
35% 72
40% 68
45% 64
50% 59
55% 52
60% 46
65% 41
70% 37
75% 33
80% 30
85% 26
then I left.

Here's what the 2015 P90D loaner I had pulled on the same SC on the way back home (same temps, etc.):
5% 53
10% 103
15% 105
20% 106
25% 108
30% 109
35% 109
40% 109
45% 105
50% 97
55% 89
60% 81
65% 71
70% 59
75% 47
80% 37
85% 32
then I left.

BIG difference. 90 battery stayed above 100 kW until about 48%, my 85 was under 100 kW by 13%. F* it, I got rid of the car and bought a gas car. Only regret was not trading it off sooner.

I compared my SuC speeds before and after the problematic update. The time it takes to go from 30 to 80% increased by 22%.

This is because the charging speed in the middle of the cycle is higher than before.
