I plugged the 120v charging cable that comes with my new 2014 FFE into a garage 120V outlet thru a "Kill-A-Watt" device so I could check voltage and current draw.
When the car was charging at maximum the voltage dropped to 110V (due to the high current over the power cabling to that far side of the garage I assume) and the current draw was about 11.5Amps, so about 1270Watts giving 1.27KW/hour during active charging. The Ford charger cable unit green light was blinking during the charging process.
When the car reached full 100% battery charged, the green light went steady for a while.
But later it started blinking again even though the battery was fully charged and seems to draw about 0.5Amps in this state. This is with the car "off" not in auxilary mode so no climate control, no lights no, no accessories on.
What is the car using that 0.5Amps at 120V (about 60W) for when the battery is fully charged?
The temp in the car this afternoon is in the mid 80s probably for reference, so it might partly be the car keeping the battery cooled?
How about the 12V lead-acid accessory battery? Does the car have it trickled charged in the state when the charge plug is in?
I've ordered a 240V 30A charger unit thru Home Depot yesterday with their special $100 off discount that expires today.
So I'm curious what is the current draw with the 240V unit in that same state after the battery is fully charged?
I don't know of anyway to measure the current on a 240V line easily (after ask an electrician about that when I get quotes for a 240V installation) like I can do with the Kill-A-Watt device on the 120V line.
