charging issue

[murray l]

I subscribe to FPL Evolution which is a flat rate electric charge. I have a 220 / 60amp breaker. My Y charges at a rate of approx 45 miles/hr however my CT charges at a rate of appprox 27 miles/hr. I've move the cable back and forth between the 2 vehicles with the same result. I've also changed the adaptor, again with the same result. Therefore I've ruled out a wall charger issue.
Has anyone experience a lower rate of charging with the CT ?

CT uses more Wh/mile so less miles per hour of charge at the same sane power. Both vehicles should be showing 48/48 on the user interface.

I am showing 48/48 & 27/mi/hr
so what I'm experiencing is normal for the CT ?

Yep totally normal
48A*240V = 11,520 W / 380 Wh/mile = 30 miles minus efficiency and active vehicle system energy (thermal managementand electronics).

Thank you very much
I’m relieved as i thought i was having an issue during my first week

Happy to help, it's a common reaction from people with other Teslas.

Btw
Why is the MY charging at 45/miles per hour

Why not? 11,520 / 45 = 256 Wh/mile

It's not the mph that you should be looking at, it's the amperage and voltage. i.e., 48/48 @240V.

The MPH is like filling a gas tank of a Prius and an F-150. The hose pumps the same amount of gas, but it takes a lot longer to fill the tank with enough to get 400 miles (~20g) vs the Prius (~5g). so the gph that you are pumping for the F-250 is less than the Prius.
