There is no CCS upgrade for your year.
There is now but..... I ordered it for my 2014 MS 60 and was anxiously awaiting for today when it would be installed. After it was installed and CCS Enabled showed in features, I excitedly went to an EVgo supercharger that has both CCS and NACS plugs. Neither worked!
I called Roadside Assistance and was first told that my MS 60 needed its 40kW battery pack upgraded to a 60kW battery pack. I pointed out that it IS a 60kW battery pack. Then I was told some nonsense that SuperCharging "wasn't a thing back then"! I called BS on that too!
I was put on hold for several minutes and then told that my car doesn't support SuperCharging, that it would require a hardware upgrade. I pointed out that ONE HOUR EARLIER I had the CCS Kit and retrofit installed. I was then told that it was some other upgrade, I believe the internal AC/DC charger (I asked the tech what was required for Tesla SuperCharging and he mentioned this but said the CCS was completely separate).
I was then told a Service Manager would call me. Previously I had inquired about adding SuperCharging to my car but was told it was a $2500 upgrade. I don't take long road trips so held off on this. When I saw the CCS Upgrade was only $450 it looked like a great alternative for 20% the cost. Nowhere does it say the car needs to already support Tesla SuperCharging, which mine doesn't.
When the Service Manager called me back he confirmed that my car didn't support SuperCharging and when I inquired what that would cost he said $12,000!!!! I asked him if this was for a new battery pack but he said no, that it was something else. I questioned this and mentioned earlier being told it would be $2500. He double checked it and again said $12,000. That's INSANE and I told him so.
He apologized that this wasn't caught earlier and refunded my money and said he'd have a tech come out and de-install the retrofit hardware.
I went to the EVgo station intentionally with a low SOC of 15% (when I arrived) expecting to test both CCS and NACS methods and estimating a chargee rate of 75kW.
Instead I sat at a level 2 destination charger for 2 hours charging at 6kW to get enough charge to get back home all because the SC didn't check the pre-req's. The tech said I was the first person in the area to order this! Thanks Tesla!
