I wonder if I might ask the group some questions. I'm a bit worried having just recorded data from LeafSpy Pro.
I have a 2016 Leaf with a 30 kw-hr battery pack and I just installed he LELink into its port on the car and downloaded and started LeafSpy Pro. I purchased the car exactly 5 months ago, have driven 2,380 miles . We charge mostly using a local (Chargepoint) 240 volt 6.6. kw charger, occasionally with our 120 Volt home plug, and have charged using a QuickCharger exactly 14 times.
We have driven EXCLUSIVELY in "Eco" mode (and I do mean, "exclusively"), and we have never driven faster than 65 miles per hour on the freeway. We have, however, done some hill climbing (up to a hiking spot about 5,000 feet above where we live, but on a gradual uphill climb on a paved road). The highest temperature I have ever seen on the battery is five bars, but that is an extreme. The usual temperature is 3 or 4 bars.
I get the following readings from LeafSpy Pro:
46.3% State of Charge (SOC)
AHr = 71.02
State of Health (SOH) = 89%, 359.5 Volts
Hx = 85.64%
LeafSpy Pro reports 14 Quick Charges (and I think that is right) but 72 (seventy-two) Level1/Level 2 charges. That latter figure simply can't be right. If it were, we'd have driven the car much more than 2,300 miles as we charge when the SOC gets down to around 30% or so. That would also mean that in 5 months (exactly) of ownership or about 150 days, we'd be charging every other day which is nowhere near the case.
Most worrisome is the SOH at 89%. That means we are about to lose a "bar" on the battery after less than 2,500 miles of what I think is very conservative driving. For what it is worth, our miles per kw-hr average has been 4.4 to 4.8 according to the Leaf CarWings site, and comports with the readout on the Leaf dashboard.
Because I read that charging at a QuickCharger to about 100% can level out the battery cell voltages, I just took the car to a nearby QuickCharger and Charged to 96%. There was no change at all in the State of Health at all. It remained at 89%
Questions:
1. Do I charge the car fully to 100% in order to determine the SOH of the battery pack?
2. If the SOH is really 89% (say, after charging to 100%), do I report this to Nissan?
3. Or, could all of this be due to either some error from the LELink or my stupidity in reading the LeafSpy Pro screens. I did set the Battery Size to 30kWh on the setting screen and chose the model year as 2016. Perhaps I missed some other critical setting.
Thanks.
PS: If there is a way to post images from LeafSpy on the forum, I'd be pleased to do so. Might someone instruct me as to how to do this? Perhaps from DropBox?
