Should I Buy this 2014 leaf s?

Thu Jun 08, 2017 6:02 pm

Your thoughts on a leaf I'm looking to buy. 2014 s with dcqc and 6.6 charger. Here are some stats.
30k miles manufacture march 2014. It is a lease return.
Ahr is 58.6
Soh is 85
Shows 12 bars
9 qc
766 l1 l2 charge
Nd 82.65

Drove 22 miles in 108 degree weather
Ac on full
Used 93 gids
Soc from 82percent to 49.8percent

Thoughts on purchase? Asking 7k for it.

Based on the 32% discharge test you did, expect the full range to be about 70 miles.

84 miles (when new) x 0.85 (SOH) = 71 miles, so your test drive would seem to confirm that the Leaf Spy data is legit (no BMS reset).

It's going to lose the 1st capacity bar very soon.

Sounds like you live in a hot climate, so only buy if you can live with 50 miles of range between charges a few years from now.

Can you update your location info via your user name in the upper right > User Control Panel > Profile tab? That way, we don't need to ask in future posts/threads or do sleuthing to deduce it. Your handle implies you live in AZ, but I don't know how hot your area is. But since you mention 108 degrees, maybe Phoenix or even hotter?

What are your daily driving needs in terms of miles? How much city vs. highway? Will you have the ability to charge at your work/destinations?

Where did the car reside before? When was the original in-service date?

If you're in Phoenix, I'm going to guess (w/the limited info so far and thus guesses I have to make) that it might lose enough capacity to be eligible for free battery replacement before the 5 year/60K capacity warranty expires.

Yes. I live in az. Phoenix to be exact. This leaf is from California. My commute is 20 miles each way. I do not commute during summer. I am an educator and summer I only would use it for short trips as needed. We have a family minivan for traveling on trips.

Where in California? Palo Alto is a lot different from, say, Bakersfield in terms of charging temperatures.

Based on the 32% discharge test you did, expect the full range to be about 70 miles.


That would be with no A/C, heat or freeway driving. A more realistic range would be 60 miles. My 2013 with SOH of about 87% has a usable range (without going much below LBW of about 60-65 miles in Summer, and that's with no freeway driving and reduced A/C use.

The most offensive, tasteless phrase in use here is "Pulled the trigger." I no longer respond to posts that use it.

I was basing that estimate on the empirical numbers the OP provided.

Drove 22 miles in 108 degree weather, AC on full, used 93 gids, SOC from 82% to 49.8%


Since GIDs are linearly related to kWh, the 32% drop is odd since (93 GIDS x 80 kWh/GID)/0.32 = 23 kWh of pack capacity. I must be misunderstanding something, or the SOC drop is inaccurate, because I would have thought his useable pack capacity would be closer to 18 kWh. 23 kWh seems way too high.

Anyways, here's my math:

Driving 22 miles consumed 93 GIDs (93 GIDs x 80 kWh/Gid = 7.4 kWh) while driving in extreme temperatures. Based on his 85% SOH, I conservatively estimate his pack capacity as 18 kWh.

So, (22 miles x 18 kWh)/7.4 kWh = 53 miles total range when driving at those extreme temperatures.

So, you're right, I was overly optimistic about the improved range when driving at more moderate temps.

FYI, I found this chart online, which shows the impact of ambient temperature on range:

According to that chart, at temps over 100F, the range with a "typical" Leaf pack would be a little under 60 miles. Amazing what a difference temperature makes, considering wind resistance is lower with higher air temperatures. Based on the chart, there's roughly a 25% drop in range between driving at 70F and driving at over 100F. If so, 53 miles at 108F would translate to around 66 miles at 70F.

Presumably that chart is based on actual miles driven with climate control as selected by real world users?

Indeed, for the OP, see viewtopic.php?p=464260#p464260.

Half Moon Bay to Livermore is under 52 miles, yet on one of those days, the former had a high of 61 F and the other was 102 F.
