Air conditioning reduced supercharging rate maybe reduced

[RichardandElse]

My Model S Raven went to Tesla for an air conditioning repaire. A leak was detected and a new piece is ordered under warranty. This will be fitted 3 weeks from now and a message on the dashboard reads as below. Charging at home normally takes 5 hours and now 20 hours with 13 amps. Can anyone advise how much longer it takes on fast chargers? I have a 7.5 hour trip ahead of me and require 2 charging stops but questioning if I should use an alternative car. Comments appreciated

If the a/c is on your charging rate is severely reduced, especially when charging at 15 A. What is your ambient temperature?

 

[RichardandElse]

18-15 deg c

Go to service mode and check for any error message

Thank u for your reply. However if u read my question, it is how much longer does it take to charge at Tesla fast chargers - beyond the normal. Has anyone experienced similar and can advise me?

The AC unit and battery/ charging components are on a shared coolant system.
If the coolant is low, charging speed is reduced to prevent damage

Any idea what extra time it will take x 3 or more at charging stations please?

Super charging bypasses the charger inside the car so the charging time may not get affected specially given the fact that battery needs to warm up for super charging.
The problem is that the battery needs to cool down after super charging, and if your coolant is low, the hot battery would reduce your range

Perfect, that is the answer I was seeking. Thank you very much indeed. We will use our other car as it will ultimately be quicker and I do not wish to affect the battery in any adverse way.

The charging rate WILL BE AFFECTED SEVERELY no matter what method is used - the cooling system is used to cool the battery, so if you are having compressor issues, this is not the right vehicle to take on this trip.

It depend on low and what percentage you want to charge to. But normally for me, going from 15% to 90% at the supercharging station take about 45 minutes. But I have a older model S. The newer ones are faster.

Yes thanks. We now will drive in our old Peugeot 5008 diesel. Many thanks for your input. Ciao

You won't charge at those rates with the cooling system not working properly. The battery is protecting itself on AC charging, it will also protect itself using DC Supercharging. The only way to test for your car is to take it to a Supercharger and see what it takes. Otherwise, I wouldn't use this car on a long trip if time is important.
