Re: 2019 "60 kWh" Leaf e-Plus

The Target in Glenview IL, is listed as a 50KW charger for both Chademo and CCS. I only peaked in the mid to upper 40s on that station.
Guessing it’s a gen 1 dcfc station.

I what I posted was just one ramp down cycle. There were other cars charging at the time, so I wouldn’t take it is the absolute cycle. As the EA stations are not free (like almost all of the other Chademos in the area), I only charge there as a kind of science experiment.

Thanks, all. That's helpful. So then just anecdotally, based on only Doug and Learjet's experiences, it would seem the Leaf Plus charges at above 70 kW on 200 amp EA stations until about 30% SOC if other people are charging at the same time as you, but until about 42% if you're charging alone. Dave, that's a good question about the percentage of EA Chademo chargers where Leaf Pluses can actually charge at around 70 kW. Does anyone know? I was under the impression that it was most if not all - I thought they were mostly all rated for 100 kW, even though they're labeled as 50 kW??

Ramp down is not dependent on other people charging. Its battery temps more than anything.

One attempt; batt temps (start of charge) 65.1/67.3/69.1

knee; 44.3% SOC 199.708 amps/369.213 (73.7 KW)

50% SOC; 181.135 amps /373.34 volts (67.6 KW)

55% SOC; 175.422/376.49 (66 KW)

60% SOC; 155.867/378.65 (59 KW)

65% SOC; 138.83/380.99 (52.9 KW)

70 % SOC; 120.299/384.24 (46.2 KW)

FYI; Only twice in nearly 100 DC sessions have I hit 70% SOC at 120 amps on the Slower DC's.

Of note; Some may recall my "cold weather challenge" charging against a Bolt which happened on the same day. On that test starting batt temps were mid 40's and starting current was still 200 amps but ramp down started at 39% SOC and by the time I was at 60% SOC, I was under 120 amps. This was the same EA station as the above session.

In case you are wondering; The max temp on first DC was 95.2º F. I charged 22+ minutes receiving 24.2 Kwh averaging 65KW for the session.

This isn't a surprise; My 40 kwh acted the same way when pack was cold.

You probably already guessed this; Since I am such a cheapskate, this is the only two examples charging on EA below 195 amps. I generally charge until the knee then unplug. This is how I averaged under 17 cents/kwh.

Dave,

Were your SOC's dash or LeafSpy? I assume Leafspy.

Dash?.... What is "dash?"

Your question is like "Should I rely on trump or Fauci for COVID advice?"

You could just tell him whether the SOC reading was from the dashboard display or from LeafSpy. The dash doesn't seem especially inaccurate except at the very top and very bottom of the range.

Yeah ALL the info was taken directly from LEAF Spy logs. I don't have the patience to sit there and watch the car charge.

I thought Tom’s note in this article was humorous that he wish he’d he had a consumption based GOM, instead of just a static one (aka like the other EVs) in the dislikes.

Ok,

Here is my latest thought on the quarterly adjustments. Safe Harbor warning, no science or methodology sits behinds this hypothesis.

My guess is that Nissan is quarterly tuning the amount of buffer, and with it bringing down the SoH reported to reduce the speed of degradation of the battery. In doing so, the battery post tuning is under reporting true remaining SoH. Then as the battery ages, if the battery underneath stays flatter, it can give back a little of the capacity in line with their internal model. In this way, it can help de-risk its potential battery replacements (under the 8 year / 70% warranty...same as Tesla) as well as help consumers maintain the best battery possible given their usage habits. Almost like how Tesla will throttle back supercharing on cars if its done too much to protect the brand, this is Nissan's way of doing it.

All anecdotal. We are coming up on the 1 year anniversary of our car, and it is doing well. Battery is at 95.67% and I should know in a few days if that is pre or post the last adjustment.
