How to deal with limitation of charging speed for Tesla Model S75?

[Henndi]

Hello,

recently, my Tesla Model S75 is limited in the charging power to a maximum of 81kW.
I would like to illustrate this changed charging behavior in the ABR.
How can I do that best?

So far, I have tried to change from 5 to 10 minutes by changing the time to open the charging port because that's about the time it takes me additional to load, but this setting does not change the charging time.

I look forward to your answer.

Many greetings

Dirk

Hello, any answers available?

[Henndi]

Is there a good answer for me?

I am still looking for a good solution to work with the limitation of the charging power in the ABR, because it costs me between 5 - 15 minutes of additional charging time per stop and changes the result for my typical distances of 500 - 1,300 kilometers per day considerably. I only get 80kW charging power within 12% - 49% SOC.

The additional time during the charging processes as e.g. note 10 minutes unfortunately means that even more than the time is changed because it is now loaded less frequently and also to particularly high SOCs.

I am very interested in an answer.

Best wishes

Dirk

thought it may would be an Option to use the „max charging“ parameter per charging waypoint.

tried that by entering e.g. 80kw for a reduced S75D, but seemed to not have any impact on charging time. But maybe I am just using it wrong...

Just have recognized workaround above works for CCS waypoints, but not for SUCs. 

[Henndi]

Yes, I had the thought too. But unfortunately the maximum charging speed does not work with the SuC.

Obviously none of the admin reads this forum either, so I still don't have a reasonable solution. Mainly because the charging time is extended by e.g. 10 minutes also changed the charging behavior. I.e. fewer charging stops are made and more fully charged, so that the journey time changes even more.

@Henndi I've brought your issue to the attention of the dev team so somebody can look into it.  I do know that for CCS/Chademo charge points, you can click the gear icon next to a charger in the plan to get to the settings & manually set the kW and time or final SoC, and it will recalculate the charge time (as @limpel pointed out).  It appears there might be a different thing happening for Teslas.  If it turns out to be a bug, I'll make sure it gets addressed.

@bjg222Thanks a lot.

Lately I've had other cars too, e.g. the Smart ED, problems with the loading time calculation on a certain SOC.

The charging speed was calculated far too low even though I had stated 22kW. There is definitely a bug in it.

@Henndi As a short term solution, you can now choose "Limited Supercharging" for older Tesla vehicles, which will assume a lower rate of charging while calculating stop times.  To enable this, go to the Settings cog at the bottom of the planning side panel, then go to the section to update your car and click the gear next to it.  Click on your car model to choose a new one, and select your model/year/battery size.  At the end, you'll get another pop up (seen below), where you can choose "Limited Supercharging".

Does this help with the issues you're seeing?

@bjg222

Yes thank you. That helps a lot.
Since the limitation, I have made around 50 supercharger sessions and have created the following rule of thumb for the loading times (with warm battery) in the different areas:

Charging Speed Tesla Model S75
6 minutes 10% - 20%
6 minutes 20% - 30%
6 minutes 30% - 40%
5 minutes 40% - 50%
6 minutes 50% - 60%
8 minutes 60% - 70%
11 minutes 70% - 80%
15 minutes 80% - 90%
=> 42 minutes 20% -80%
=> 57 minutes 20% - 90%
=> 23 minutes 10% - 50%
=> 29 minutes 10% - 60%
=> 37 minutes 10% - 70%
=> 48 minutes 10% - 80%
=> 63 minutes 10% - 90%

If I compare this with the current route planning for limited vehicles, it fits most of the loads.

I only need longer with two loads of 10% SOC to over 70%.

The loading curves seem to be somewhat different. If you want my records, I tracked everything with Teslafi and Tronity.io, I will be happy to provide them to you.

@Henndi That's useful info, thanks!
