In the car, yes and in the app, yes changed to unlimited several times, everywhere before I plugged in a few days before I started charging


I have been AC charging at several areas as I have driven the car a fair amount in the 3 weeks I have had it and everytime I start a charge with a new AC charger I have to change to 38 amp max

I saw that when had location based on. I turned it off and set to unlimited and now seems ok and keeps that.

Does this look right?

given that you are on a 50A circuit, yes that is exactly what you should expect to get.

**Edit**
I only looked at the number of amps. As mentioned below, 8kW means the voltage seems very low and a 40 A charger should provide closer to 9.5 kW.

Thanks! After 20 min it went up a little over 8kw

Soooo, the one thing that looks sus to my eye is that the car & app both report about 8 kW charge rate. And the app is showing 40A. So, that would suggest that the voltage is only 200V. That seems extremely low.

Can anyone else chime in

His math is correct. I only payed attention to the amps when i replied. I didn't think to calculate what the kW output should be at 240 V ... So in theory, a 40A charger can send up to 9.6 kW. Getting only 8kW is indeed a little weird but that might just be the reality of the grid in your area (which is why voltage ratings are usually a range).

This is the type of stuff an electrician can/should check for you.

Turned off charge after 2 hours to run some errands and breaker feels warm to the touch. Not hot but a little warm. Is this normal?

I have the Emporia EVSE too. The app displays “monthly peak 15 min demand” which is different from the current rate of delivery which is displayed in the “rate” field in your screenshot. You were charging at 40 AMPS which is where it should be given you have a 50AMP circuit breaker.

The “units of measurement” setting in the app can be set to a variety of units, including watts and amps. You have yours set to amps. If you change to watts, your “rate” field will display current rate of charge in kW.

Hope this is helpful.

Did you have a licensed electrician do the installation with the appropriate permits and inspections? If so, they would probably be the right person to ask.

It was showing kw on the left side of the screenshot

Warm to the touch is ok, shouldn’t be hot
My first Juicebox unit , was hot, so hot I could barely touch it

They replaced it and now just a bit warm

Not the unit itself? The 50aml breaker that gives power to the unit

Yes, my breaker was very hot and the plug itself was super hot

Just making sure thats normal. Well not the hot part but the warm breaker from cherging the car

Yes a warm breaker can be normal. Mine now is a bit warm but that’s it.
Also I have read that it’s recommended to have the connections checked once a year to make sure nothing gets loose, Especially with a 14-50 outlet.
