Re: The 62kWh Battery Topic

Fri Mar 27, 2020 1:09 pm

I've now had my Leaf Plus for a year, so here are a few notes about my battery.

Mileage: 14,200
Ahr: 168.57
SOH: 95.56%
Hx: 113.29%
Charging: 36 L3 and 158 L2

We've experienced four adjustments of the reported Ahr, approximately every 90 days: 1.0, 1.3, 1.37, and 0.25 Ahr.
My wife is the primary driver and generally plugs in when the battery is down to about 50%, then charges to 100%.

So, we've lost about 4.5% capacity in the first year. If we kept losing capacity at that rate I wouldn't be very happy, but it does look like the rate of loss slows after ~7000 miles. If I spread out the losses from each of the big drops evenly over the preceding 90 days, the rate of loss was 6.2 Ahr per 10,000 miles at first, slowing to 3.7 Ahr per 10,000 miles. If it continues at that rate, I expect to have ~77% capacity remaining after 100,000 miles when the battery warranty runs out. There are a lot of unknowns, so that's of course just my best guess at this point.

Need to convince your wife to run SOC between 25 and 75%.

Your ahr dropped over 1 but your SOH went down .06%? That is weird.

Here are a couple of data points from my car: Initial LEAF Spy reading at 64 miles on 8/11/2019: 175.15 AHr, 99.29% SOH, 98.19% Hx, 1 QC, 6 L1/L2, 64 ODO. Tonight at 14,164 miles on 4/2/2020: 172.77 AHr, 97.94% SOH, 113.77% Hx, 4 QC, 103 L1/L2, 14,164 ODO.

The car was manufactured in July 2019 and purchased on August 10, 2019 with 30 miles on the odometer (my dealer picked it up the day it was delivered to a dealer across town).

Edited to fix manufacture and delivery dates 2019, not 2020).

Must mean manufactured in 2019 not 2020? I know we live in weird times, but......

Good to have these Arizona numbers, thanks much for posting.

On the dates, I think you meant 2019, not 2020.

On the data discussion, I don't fully understand what I"m looking at, but it seems like they're holding up "pretty well" or "ok" for about 9 months and 14k miles. It would be really great if in the end the Leaf+ batteries do hold up in the heat, over several years and thousands of miles and dozens of vehicles. Some of us simply will not consider buying one until there is proof.

Well, given that during normal running, Tesla is quite comfortable at leaving its batteries at between 30 and 50 C, I think many of the newer chemistry are in their sweet spot at a higher temp.

This means that the chilly cold batteries in Canada and the American North will no longer have a longevity advantage....maybe its worse for them?
