Recently purchased a 2017 30kWh S trim Leaf; I'm the third owner, and I know the previous owner as a friend. Car appears mechanically and cosmetically in great shape. Dash indicates 9 bars of battery capacity, and typical estimated range is 70-75 miles when fully charged. I will admit, I probably didn't do enough research before purchase, as this is an out-of-warranty 30kWh model without the30kWh battery having been replaced under warranty (never quite met requirements or had problems other than 'typical' range degradation).
We've picked this up as a 4th vehicle for our family (three other ICE cars, 2 teenage drivers). It's intended use is typical grocery, commute, school, and kid activity trips around town, with typical trips of ~10-15 miles roundtrip, and maximum range trips of 20-30 miles roundtrip. Level 1 charging available nightly in the garage at home, and L2 charging (public/pay) if needed at both my and my spouse's work locations. Trips involve some freeway driving, but due to their short distance, city road network is also available at a few minutes longer drive. For any trip plans that might give me range anxiety or would require offsite charging we'd utilize another vehicle. Location is the Pacific NW, so relatively mild temperatures.
I've purchased LeafSpy, done some analysis, and have been digging through the manual; see posted photos. Car has extremely limited quick charges (29); it was exclusively charged via L1 charger for the past ~5 years by the previous owner.
So, my major questions at this point:
- Is this a viable car to use as a city runabout as described for the next ~4-5 years without too much worry from a battery standpoint, or should I significantly plan for on-road failures/stranding (aside from a potential "forgot to charge" scenario) ?
- Within LeafSpy screen 1, what is the difference between red bars and blue bars? My battery reports all red bars, with cell 42 and 48 as blue, but all cells generally and typically trend at what appears to be a low mV spread (10-25 mv).
- LeafSpy SOH is 68.23%, with the Hx at 36.83%. From review of a few posts here, I may need to be concerned or at least wary of the low Hx, and the large difference between SOH and Hx. For the vehicle age, is this reasonable, or should I be watching for an upcoming cliff where the HV battery just crashes out?
- I don't believe that I need a L2 charger at home for my use case; typically spare vehicles available, and with regular overnight charging, I think I'd be OK, but I'd love any commentary from this group as to considerations I should take on L1 vs L2 charging.
A few LeafSpy screenshots are attached. the 18mV cell delta is the vastly typical screen under most driving conditions with mV ranging between 10-30 in operation, and 10-20 when at rest. The 77mV and 303mV were captured from a screen recording while driving. These were near instantaneous readings, dropped immediately, and correlated to heavy acceleration/load testing.
So Reddit community - what say you? Should I expect this to be a suitable town runabout for awhile, or am I gonna need to go pick up stranded kids from the side of the road this winter (or next)?
I don't think I'll be tackling a battery replacement; but feel free to convince me otherwise!
