Late 2013 LEAF: Last 2 years of Battery Data

Wed Sep 18, 2019 3:12 pm

When I bought our LEAF second hand in Jan 2017 it showed 64 Ahr battery capacity. This was almost certainly a reset and within 6 months the battery had settled down to ~ 90% SOH. The next 18 months the car lived in Colorado and since then it has lived in Albuquerque. Needless to say, Albuquerque is warmer. In ~ July of this year the car lost its 12th capacity bar when SOH was ~ 84%.

Regarding the data: For the most part I grab LeafSpy data about once a month and plop it into a spreadsheet. The following graph is that data.


Ignoring the gyrations through the seasons I seem to be losing ~ 0.5 kWh of capacity (about 2 miles of our type of driving range) a year. We are still able to use the car for our purposes by charging to 80% SoC so in effect we have a good 20% SoC buffer to rely on in the future when serious battery range loss has occurred. So far, no drama with the car and I remain somewhat optimistic that the car will give us another 5 years of (admittedly limited) service. Maintenance costs to date include wiper blade inserts and new tyres followed by an alignment. The OEM set had worn asymmetrically on the outsides.

I too hope you get 5 years. Keep in mind that the car will start scaling back the regen braking as the battery degrades, which may cause your range loss to accelerate, even though it may help battery health.

Late 2013 LEAF: Last 3 years of Battery Data

Another year, time for an update.
Battery aging has slowed down, but our use has been markedly affected by Covid-19 and I'm not sure how much that matters.

This LEAF will have her 7th birthday in October. As an American LEAF she has aged gracefully -- perhaps one of the top few percent and this is outside of the PNW. We do pamper her to unusual extremes but I think the larger truth is that we just got lucky with a better than typical quality battery.
