Best time to terminate L2 charge if in a hurry

If I'm charging a 2015 SL at a public L2 station at say 30amps to 100%, at what SOC does the charge start drastically tapering off. I'm sure someone has a chart just haven't been able to find it. Thanks

According to a poster on this thread: http://www.mynissanleaf.com/viewtopic.php?f=6&t=13008" onclick="window.open(this.href);return false;, the charge rate drops off at about 85-90%. So, if you stop at that point, you'd probably be saving yourself some money on public charging.

Unfortunately, I don’t know because I don’t have time to run around to my work’s parking garage when I see the car ramping down on Chargepoint’s web site, esp. if I have to park far from my desk.

Today, I did see my car had begun ramp down and for a 5 minute interval (that’s the resolution Chargepoint provides on their web site), it was down to 4.17 kW. A query via Nissan’s Leaf app showed all 12 bars and 0:50 time remaining at 6 kW.

The next 5 minute interval showed 3.09 kW.

So, 12 bars isn’t “good enough”. I think if you hit 98% per the car’s % SoC gauge and it says 0:40 remaining, that’s probably a good a time, or you’re already past it.

You may see the 98% “jump” to 100% upon unplugging (http://www.mynissanleaf.com/viewtopic.php?p=350851#p350851" onclick="window.open(this.href);return false.

If it helps, here are some kW values in 5 minute intervals after 3.09 kW:
2.42
2.09
1.71
1.30
1.22
1.09
1.08
.80
.77
0
and so on. My car has now begun its “bounce” phase. My work's L2 EVSEs run @ 208 volts and can supply up to 30 amps.
