Do I have a charging problem with Rivian Wall Charger?

[danen1973]

I’m trying to figure out if there is a charging problem with my Rivian wall charger. If you look at the pictures there are several places where charging speed is displayed. They don’t match? Which one is accurate?

How going into the battery vs out of the charger is going to vary due to heat and efficiency loss.

Yeah the car only knows about how much energy it put into its battery or consumed running accessories etc. The charger only knows the amount of power it has delivered.

As HaveBlue said there are losses between the wall and the battery because some power loss occurs when the onboard charger converts the AC from the wall into DC for the battery.

At 48 amps charge rate you should expect to see 11.6kw coming out of the charger.

What is the air temp? Maybe some is going to battery conditioning. Your charge rate looks just like mine but I never looked at the charger.

Also the app seems super buggy. Depending on the screen, the range estimates are different. It doesn't really know what car I have as far as battery size or wheels. So take it all with a grain of salt ions.
