EU CCS Charging: chargespeed & stations

[robertvg]

Journalists testing the Model 3 in Netherlands on a Fastned CCS charger: up to 75kW.
But this station was limited in power because it didn't have a liquid cooled cable, apparently (much?) higher power should be possible. We are eagerly awaiting results from other charging station

Nice, I want to see it on 200+kW CCS with a warm battery

Seems it would look like this (battery temperatures not mentioned.):

Likely taken in the Netherlands today with temperatures around 10 degrees C.

Saw a pic today of a M3 charging at 117kW on a non supercharger.

I have nothing to back this up but I think they are still software limiting it until SC v3 is out.

Crazy that the best charging curve for a Model 3 is actually on a non-Tesla charger.

Why is that crazy? There are chargers that can put out more power than a supercharger just few cars that can use it right now.

I'm so confused. Isn't this almost exactly the same charging curve as a regular 120kW supercharger?
Also this appears to be measured at the charger instead of the car which could account for the few percent difference.

Yep, makes me wondering as well.

IF this is the maximum charge rate a model 3 can do, then upgrading the superchargers to a "version 3" shouldn't make charging more time efficient for model 3 owners.

Guess it shouldn't be true; but IF this isn't the maximum charge rate a model 3 can do, then it could be Tesla is artificially lowering the max. charge rate on third party networks.

Maybe i miss some options, i'm not that smart...

Tesla Model 3 Charges At 117-kW On CCS

That curve appears to be the same as with SCv2.

I have followed a few of the Model 3 tear-downs and they say the internal 3 cabling is capable of more kw than the S/X. The EPA also says the 3 can take 500ish amps. I feel it is very likely that the European Model 3 are "only" hitting 120kw as a result of a software limitation that will be removed at some point.

The graph shown above also looks like it would "naturally" have a higher peak, rather than a plateau that just tanks. To me this also suggests the 3 can take 120kw+ all the way from 0% to somewhere in the mid 40% range. The 18650 packs have a much more gradual looking taper.

You Think The Tesla Model 3 Supercharges Fast Now? Just Wait ...

Tesla Model 3 reaches new record charge rate of 126 kW – faster on CCS than Superchargers

Yep, you have to remember that these are 150kW/175kW CCS stations, and their maximum rate is usually calculated at 500v. So they are capped at 300A/350A. And if you figure that the Model 3 tops out at ~405v that would give it a maximum charge rate of 121kW/141kW. But of course when the voltage is that high the charge is limited. So that means that the 126kW charge rate was probably achieved when the pack was at about 360 volts.

The real test will be when someone takes a Model 3 to a 350kW CCS2 charge station that tops out at 500A. Then we will really see what the capabilities are.

This is ridiculous. It hits 126kW only from 44%-48% SoC, the rest of the plateau is very close to 120kW.
Now, if the Model 3 is capable of faster charging it will be only be at lower than 50% SoC. So you'll only get a significant benefit if you're very good at arriving at the charger at a very low SoC.

I see what you are saying, how it jumped from about 120kw to 126kw in the 40% range. However, I don't look much into that. I have never seen a lithium ion battery that takes its peak charge in the 40% range. I am guessing the battery was warming and was able to hit the max rate in the 40%'s as a result, or it could just be a measuring error. From what I know, I think the Model 3 will take meaningfully more than 125kw from 0-40% SOC when the right chargers and conditions occur.

The great thing is, with a 300ish mile range, even if you can only take 120kw to 50%, that gives you around two hours of driving in about 15 minutes, which is awesome. 300 miles to start, 15 minute stop, then another 150 miles. 450 miles with a 15 minute stop.

I'm not saying that isn't true. But looks to me the charger is rated at 400A.

to me it seems clear tesla is still limiting it at the car. if the mid range can hit ~120KW which we know it can then the LR should be able to go over it fairly easy.
