Supercharger Avg Power

[vvgogh]

What are you getting for average power from Superchargers? Unfortunately, the charge logs don't have the curve and more informative times to 80%, but here's a few recent ones. We can only use the 250 kW chargers, so we should only be bottlenecked by what the Lightning will accept. The superchargers share power, so if you don't get a bank to yourself, you could of course see a slowdown from the sharing.

• Rifle, CO. 14% to 84% 95.5 kWh in 58 min. Only 99 kW average despite an early peak 170 kW peak. 95F and no one else charging
• Parachute, CO. 27% to 90%. 87.2 kWh in 54 min. 97 kW average
• Silverthorne, CO. 47% to 70% 33.3 kWh in 14 min. 143 kW average

The Rifle and Parachute chargers are only giving around 100 kW average up to 80% despite an early 170 kW peak. I've been to both a few times and it's been a consistent experience and not tied to a shared supercharger. I'm not sure if the slowdown is on Tesla's side or Fords when it occurs. The Silverthorne experience above suggests the Lightning may not be culpable for charging slowdown.

we all know why they are slowed down on non Tesla come on

This was from my trip last weekend. It did slow down to around 109kW as it got above 80%

Average speed will always be slower when you go past 80%, due to the curve dropping off the cliff there.

I got a steady 188kW at a SC in Vegas last week from 50 to 70%

No one has ever seen over 40-ish KW above 80% before.
I don’t know if you’re lucky or cursed.

The slowdown is your state of charge. Going over 80% and the kWh tanks, go over 85% and it tanks even more.

So your three examples are not scientifically relevant as the variable are extremely different

Mine would reliably go to 60 kW at 80. Never charged above 85 so I don’t know when it drops next, but it seemed like 60 was the requested power at 80%.

Op, ambient temp appeared to make a big difference for me. In the 90s and my speed would drop to around 100, but when charging in the 70s it was around 123.
Superchargers have been the fastest and most reliable chargers for me. I have not done a ton of fast charging but SC sites always supplied more power and we're more consistent

Gen 1 tesla chargers would share power between two stalls but that is not true for v2 and up. The only limit may be if it nears all stalls being occupied and they hit the limit for the entire site.

I saw the speeds peaked at 165 or so for me on my trip up to Maine last week, would settle in between 109-115 after the initial boost and then go to 45 once it hit 80 which seemed normal. I'm sure I could have gotten a faster charge to 80% but in the end using the Tesla network saved me quite a bit of time over last years trip north between derated charges and waiting in line for one to open up.

I don't believe that the V3 or V4 locations share power like you think, it is the older locations.

We are bottlenecked by the CURRENT output of the charger (500A); it’s not the kW rating of the charger that determines how fast our Lightnings charge, it’s the maximum current output, which is 500A at an EA 350 or Tesla SC. The relatively low voltage of our Lightning’s battery pack (mid-300V) means we can never see more than about 170kW from 500A.
340V x 500A = 170,000W or 170kW (get it?)
If the Lightning had been designed with a higher voltage battery pack, we might see higher charging rates from the available 500A; but, that’s the way it is, and it isn’t going to change. It’s highly unlikely anyone’s going to make a DCFC that outputs more than 500A. So, if you’re seeing about 170kW on a DCFC, you are getting the fastest charging possible on our Lightnings.

**if the DCFC is limited to less than 500A (say, 350A) then we get even less charging kW:
340V x 350A = 119kW
When chargers are “administratively” de-rated, it’s the current (amps) output that gets throttled down.

I wonder how long the "mishmash" of charging station station outputs and costs per kWh will last. It doesn't feel like the normal "market forces" are at work yet. I understand that this is still new for CCS (so to speak) and Tesla has an early start with a built in audience and federal money is involved at the state level etc etc but it's crazy to have such a broad range of costs, charging rates and availability. Ah well, love the truck and willing to navigate the hodge podge

Just some data for your enjoyment.
I made a 500 mile round trip on PA Turnpike to Hershey this week. I charged at EA in Bedford twice (53% to 82% and 22% to 61%, both 56¢/ kWh) and Tesla (36% to 80%, 45¢/kWh) in Mechanicsburg once.
All three averaged 2 kWh/minute. EA peeked at 174 kW and Tesla peeked about 140 kW.
Speed averaged around 75 mph. Used BC about half the time.

Ford specifies 15-80% DC fast charging for ER (85 kWh) at taking 41 min. So, 125 kW is the average charging power specification. My slower experiences at Superchargers are delivering 80% of the Ford spec. This adds 10 min totaling to 51 min for 85 kWh.
