Thanks for your reply. Yeah in looking at the settings (I just purchased the car) it was set to low. There are three levels low, reduced, and maximum for 110V. Switched to maximum and will see what happens
That worked. I can basically full charge in maximum mode in about 4.5 hours. I am trying reduced overnight today. That is predicted to take about 10 hours to fully charge for near zero. i also discovered the BMW i Remote app--this is awesome and is a easy way to check the charging status.
Determine the size of the circuit breaker that services the 120VAC plug you are using.
Most modern homes are built with 15A service on the 120VAC circuits.
If you live in an older home, the service level may be less.
As long as the rated current on the circuit breaker is equal to or greater than what you set the car's level 1 current maximum to, you should be fine.
The second limiting factor is your EVSE:
The EVSE device that came with the car, also has a current capacity printed on its backside. Mine says 10 Amps on 120VAC. It will not deliver more than 10A to the car.
The third limiting factor is the configuration of the car itself.
The car can be configured to limit the amount of charging current, as you are aware.
Bottom line is, you don't want to pull more than the rated current, from the 120V circuit you are using.
If you live in a home that was not purchased new, previous owners may have altered some of the wiring in the home, and it may no longer be up to code. If this is the case, you might want to have a licensed electrician verify the wiring of the 120V circuit you are using.
Since most 120V circuits in a home service more than one 120V plug, you have to remember that the current going thru the breaker is the sum of the current for all 120V plugs on any given circuit.
So, be sure that you don't have any other high power devices being used on the same circuit, at the same time you are charging your car.
If the right checks are made to verify that the limitations of your house circuit are respected, there is no need to monitor anything, just enjoy your new car.

I have an i8 and have problems with the charging device which came with my car. I took it to the dealership and they said this is common - and are replacing it. The charging device just isn't very dependable and I have had problems any time the temperature falls outside the range of 40-80 degrees Fahrenheit.
