Should add odometer to the chart.

You had 3 plusses, one "zero" adjustment and now it looks like you have restarted the negative adjustments again. Interesting.

Sounds like a good idea. I'll add that in on my next update

I set my car time to the following settings, the "Full charge has priority" is the key one. I then have a timer on my charger that shuts it off at 7:00am. Then regardless of the charge level by 7:00am it will always be at or about 70%. I only charge at 3KW so my stop time is way out to 11:00am but if you're charging at 6KW it would probably by more like 10:00am for 70%

I like it !
Clever.

To be clear for others, 'charger' refers to the EVSE

Nice. With the Plus, I have a lot more leeway as far as an SOC target so mine is basically 45 to 55%. I plug in around 5:45 am, unplug at 7 am when leaving for work. In Winter, I lose about 2-3% SOC every morning. In Summer, I gain 1-2% SOC.

Other than that, if planning road trips, I charge to get 10% per hour to hit whatever target I need. I am within 5% with about ¼ of them being right on. I found that the earlier the start of the trip, the closer I am.

I see all the complicated things people are doing to charge to 70%...I just look at the display...if it says I need 5 hours to 75% I set the time to come on at 1:00 am and go off 6:00 am...works! If its 4 hours...then on at 2:00 am off at 6:00 am....I only change the start time.

Plug the cable in ...got to bed :)

You get the point...works for me.

I figure 3% per hour of charge added on our L-1 EVSE, plug the car in when it will be convenient for my housemate to unplug it in X hours, and leave her a note to do that.
