lilly: If you watch the Chargepoint graphs, after the 3 bounces are over, assuming you don't climate control via timer or remotely, charging should stop and power draw should be flatline at or near 0.
Every single '13 to '17 Leaf I've plugged in at work on our Chargepoint L2 EVSEs has this behavior when charging to 100%. If the Leaf is set to stop at 80% via car's UI (which Nissan removed on US '14 Leafs and beyond), power is cut abruptly. There is no taper and no bounce.
In either case, there is about a 15 minute delay (almost certainly intentional by Chargepoint) from when Leaf stops charging (in both the 80% and 100% case w/bounces) and sends its notification vs. when Chargepoint tells you charging is complete.
Example message below:
We wanted to let you know that your vehicle, which is charging at ______, is drawing very little power. Typically, this means it's fully charged, however, it may also indicate that your vehicle is configured for delayed charging. Your vehicle has accepted 14.63 kWh of electricity and has been plugged in for 03:40:14 (hh:mm:ss).
has finer resolution than what Chargepoint provides. viewtopic.php?p=448160#p448160
has a graph from Juicebox.
I finally was able to find the post of a guy who is trying to get his EVSE to stop early, programmatically: viewtopic.php?t=23741
. I embarrassingly, hadn't read his lengthy post. This is the type of crap people have to resort to if they want to limit charge level due to Nissan's removal of 80% option and J1772 protocol limitations. Otherwise, people have to improvise and guesstimate via timers/more flexible EVSEs.
