Slow supercharging

[njhtran]

I rarely supercharge but today I was in Beaumont ca supposed to be a 250kW max and nobody else here 5am. I’m getting 30kW charging at 70% soc. Search on this forum I believe should be getting over 80kw charge rate. Should I make a service appointment

30kw @70% is really not bad. If the ambient temp is very hot, and the batteries are also hot, the charge rate will be reduced, normal BMS software function. It is quite unlikely you will be able to improve anything.

There are multiple battery versions in the X, it depends which one you have. The charging speed depends on SOC but also depends on the battery temperature. Did you precondition for supercharging? That is, did you navigate to the SC enough in advance for the car to heat the battery?

You can look at this link which might help see the "optimal" charging for your battery, as well as statistics of various ABRP users with the same battery as you: Tesla Supercharging - Summer 2019 Update

Did you try other charging stalls? Sometimes the charger itself is having trouble.

Yes tried 2 stalls opposite ends of the parking lot. Same speed.

What year is your X?

Thanks for the link. I drove the vehicle for an hour prior to charging and Beaumont is in the desert area of ca it’s hot even at 4am

2016

Driving does help prepare the batteries, but if you set the supercharger as the destination the car will actively warm the batteries and provide a message on the screen to tell you its doing so. Did you get that message?

All that said, I'm not sure how much preconditioning does to aid speeds at such high state of charge. I would have expected it to be higher as well, but maybe that's just what it is for that model, year, age, of car.

Probably age of the battery involved. My 16 S charges at peak 126 but I have seen plenty of 30 at the 70% and above.

Try again with a lower battery, like 20%. The more full your battery is the slower it will charge.

I’m thinking of posting a sign on my ‘13 Model S that says “sorry I have unlimited supercharging and Tesla is Throttling my kWH - So I will be here for awhile ”

I found this article which I suppose explains the issues we are having:
