Another data point for a brand new car. Two weeks ago I leased a 2017 SV here in San Diego, CA. Mfr date 2/2017, bought on 5/14/2017. So probably sat for 3 months at 100% charge I fear because Nissan removed the 80% charge option. Here are some stats:
Upon delivery it had 40 miles on the odo, battery at 80% SOC after a 30 mile drive from the dealer's storage lot. Leaf Spy showed 98% SOH, 93 Hx, 1QC and 6 L1/L2 charges. Wasn't real happy about the 98% SOH, was really expecting to see 100% but I took it.
Drove 40 miles around town, stop and go and SOH went down to 97% in one day. Did a L1 charge to 100% and drove another 90 miles over the next few days, SOH went down to 96%, Hx 92.
Fully charged from 27% to 100% using L1 for 22 hrs (open EVSE L2 charger is on order), After driving another 30 or so miles over the next few days SOH now 95%, Hx 90.8. GIDs with full (actually 97%) charge is only 347. Whisky, Tango, Foxtrot....over. Seems my battery is taking a rocket ship ride to the basement.
This is on a car with less than 300 miles, mild weather, driving easy. Is it just me or do you agree this seems bad for a brand new battery?
I've seen 3 yr old Leafs with 20k mi with far better stats. I'm an EE and I used to design battery chargers for a living and I know how to take care of batteries and was highly anticipating taking great care of this car. Thinking of going back to Nissan soon instead of waiting a year for the first checkup to show them these numbers to document that it's the battery and not me or my driving.
Any other new 30 kWh owners with a similar stats? Is this typical?
