Timer function
 

Interesting. see below JuiceBox app screenshot, green area graph at bottom of the screenshot, on how the e-tron start and stop charging 6+ times overnight to top-off to 80% target with completion timer set at 6:25am
Details:
Plugged in at 6:28pm with SoC 56% and range 118 mi.
e-tron charge completed at 6:21:25a SoC 80%
6:28:21 to 6:28:33 (12 secs) 0.003 kWh was used ( note that Stationary climate control is OFF )
6:28:33 is when I physically unplugged for my daily commute
Juicebox was set to 20A (240V). ToU is not available for my service, and is not enabled.
line is brand new 30 ft length 6 gauge wiring - that can handle more than 40A

Any battery/electrical engineer experts here:

1. Is it healthier for the battery charging to stop-n-go multiple times ; or is it VAG to reduce current continuous current load to reduce fire risks.
2. The main wear item of the EVSE is mechanical relay which must have a MTBF with those moving parts engaging and disengaging.
3. Isn't it that when the ambient temp. or when cooper lines are hot/warm, they can handle more amp; thus less resistance , which means higher efficiency?
4. I am seeing, as expected, about 10% charging system loss from utility kWh to the approx. consumption from the dash
5. Charging at 40A vs 20A - is one more efficient than the other ? which one is healthier for the battery? if 20A is better, should we be setting the JuiceBox to the lowest amp, that will top-off the daily commute consumption?
6. I am aware that charging at 120V is less efficiency - because higher the voltage the less resistance will affect the power transfer.

Other thoughts?
