We have done a first charging test with one of the first delivered Model Y LR in Germany.

The 5C battery is well known for its "only OK'ish" charging curve and the hopes were high, that the improved cooling capacity of the Model Y would also improve the charge speeds.

They key thing here is Tesla's claim of "270km in 15 minutes". This is not an "up to" like in the past.

In the Model 3 the advertisement was "up to 275km in 15 minutes" which the E5CD LG Long Range never reached, even in ideal circumstances.

Here is the data of our first charing attempt under pretty much ideal pre-conditions:
  • Long drive over the Autobahn with SuC V3 set as destination and long time to precondition the battery.
  • No charge limit due to high demand at the SuC stall.
  • Plugged in at 4% SoC and up to 100%.
Did the Model Y LR (LG 5C) manage 270km in 15 minutes?
  • Charge start at 15:57 / 4% SoC / Range 42km (real range including buffer below 0% / rated consumption of 148Wh/km)
  • Charge end at 16:12 / 47% SoC / Range 249km (real range including buffer below 0% / rated consumption of 148Wh/km)
  • 207km in 15 minutes / 23% off!

Capacity calculation:
  • 494km@100% → 494km x 148Wh/km = 73,1kWh
  • Energy Screen → 171Wh/km x 431km / 100% = 73,7kWh

We have done the calculations on about ten Model Y LR now and all of them were in the range of 72-74kWh.

I can only advice everyone receiving a EU Model Y to do a charge test under the following conditions:
  • Drive at least 30 minutes with a SuC V3 as destination.
  • Confirm that the car says "preconditioning battery for fast charging" on top of the navigation bar.
  • Arrive at the SuC V3 with around 5% and no more than 10% SoC.
  • Verify that the SuC is not overly occupied with many cars charging at the same time.
  • Plug in the charger.
  • Write down the time or take a picture of the (whole!) display at the moment the charging begins.
  • Take a second picture as soon as the recharge counter hits 40kWh.
  • Subtract the times to see how far off your charging session was of the claimed 15 minutes.
  • (My best session was 22 minutes → 32% off!)
Calculation why the marker is 40kWh:
  • The consumption of the Model Y is 148Wh/km based on the EPA test cycle.
  • The European WLTP consumption reduced by 12% for charging losses is 148Wh/km.
  • The car calculates its rated range based on a fixed rated consumption of 148Wh/km set by Tesla.
  • 40.000Wh : 148Wh/km = 270km

I think Tesla needs to make some tweaks to charging curves if they can. If they can’t the honeymoon may be over until the 4680 batteries come out. But everything is based on Elon time so there’s no telling when that will happen.
 
Those battery packs (LG 5C 75kWh) first went into the China made Model 3 in December of 2019! The charging curve of these (by now) "old" cells was way worse than the Fremont/Panasonic cars and hasn't improved since.

We have compared the charging curves since this battery pack first came to Europe in Q4/2020 as the Refresh Model 3 Long Range.

Tesla SeC's kept saying that an update was imminent when customers complained that their cars weren't able to charge the 275km/15 minutes, but it just never came.

I hope I am wrong but I think too much time has passed and it is a clear sign that these LG cells are at their upper limit and no update will change their performance any further.

It is just a shame that Tesla isn't launching this car with a better battery pack in the EU. Surely this was a case of either launching it with the cells that are readily available or not launching it at all.

This is also in big contrast to the US were the Model Y is actually over performing, since Tesla has secretly transitioned the 78kWh Panasonic packs to 82kWh Panasonic's without officialy increasing the range (yet). Q4 will probably make it official...as Model Y 2022 and an updated range that reflects the 82kWh packs capacity.
 
Bjorn was only able to get 70kWh out of the Model Y he tested, looks like he got unlucky with a car that has lower than average capacity?
See Post 1:
"We have done the calculations on about ten Model Y LR now and all of them were in the range of 72-74kWh."

This calculation includes the Buffer below 0% that BN normally doesn't take into account.

They are all in that range, but the LG pack actually can calibrate itself a little bit upwards initially. 75,#kWh are possible.

Right, I forgot he doesn't add the lower buffer back into the capacity calculation.
 
Hello @eivissa,
Do you have any information regarding Model Y(EU) battery coming in Q4?
I thought Tesla were going to send new LG batteries but the order opening in the UK for delivery in Q1 2022 and a 507km WLTP autonomy makes me skeptical ..
Nothing definitive. I still believe that we will see the new LG 5L 80-82kWh battery packs in Q4/2021. Certainly in the Model 3 as E5LD with 614km WLTP, but probably also in the Model Y as Y5LD and 542km WLTP.

Hongkong is expecting delivery's of the Model Y with 542km within this quarter. China has just raised the range according to their measurements in accordance with the raise from 75kWh to about 80kWh. Also we know that there could/should be a range increase with the new Panasonic battery packs (3L) for both M3 and MY in the states as a 2022 model year refresh.

Tesla could still prepare a range increase for most of their cars worldwide within this quarter and this change in the configurator could come anytime.
We know how this will be done, but not when...

We've also seen new Matrix LED lights in Giga Berlin, we've seen M3P v2.0 and MYP v2.0 in the source code, we know that the Model S Plaid front motor should also fit into the Model 3 and Model Y rear, we've seen air suspension sneak peeks in the source code...

Model 3/Y 2022 could be a much bigger thing than just the range increase. Still...a lot of guessing and connecting dots, but nothing certain.
 
thanks for all those details @eivissa.
Let's wait for the 2022 Model Y to show up.

BTW, I'm was asking those info because I have a MY order planned for this quarter ..
I'll ask my TA to wait for 2022 Model Y later this Q then, or at least to wait for the first MY delivery in EU to know if they are 2021 or 2022.

Inventory cars are appearing via third party sites now, this one has a build date on 11 Oct and is still using the 74/75kwh LG battery. If they have changed the battery, its very recent and getting tight to get here for Q4. I must admit I'd not want one of the early deliveries this quarter.
