calculating charging rate

[Peterch]

I am sure I have read this on here but cant find it. How do I calculate the rate that my car is charging?
I am sure it looks at the battery size and voltage but cant recall how to calculate. Mine is a pre facelift long range?

Flick through until you get to Voltage and Current then multiple V x A to get Wattage.

Tried this but screen wont change when charging?

Did you put it in ready mode?

I just realised you have pre-FL so probably doesn’t help but the app on FL shows you this.

As @Jomarkh said above, when charging foot on brake and press start button as if you were starting the car normally. It will display warning messages and you can press the OK button to get rid of them but the car won't actually start. Then scroll down 3 times to get to the power page.
