With the ELM327 available now for everyone to use with their smart phones, we should make a compilation of the results from everyone. Showing the age/mileage of the car. General operation condition of the car (batt temps, mileage on car, DCQC?, frequent 100% charging?). I started logging my data. At first I was relieved that my battery capacity was 96.68% (64.06 AH) at the beginning of last month (May). However, here we are, not even at the end of June yet, and my capacity hasbeen steadily falling from the 96.68% down to 92.88% yesterday. (64.06AH down to 61.54AH). Kind of has me concerned, considering I have never DCQC the vehicle, charge to 80% most of the time, and live in relatively mild temperatures.

Yesterday I went to test drive the Spark EV today at Bunnin Chevrolet. (Culver City). Took the drive there in the LEAF. Trip was 52 miles. Left with 100% charge...got there with 3 bars remaining, averaging 4.8mi/kWh..(27 mi on the GOM, 39.4% SOC on the ELM327). Charged at the Chevy Dealership for 3 hrs to get back to 9 bars. Only made it to 97 mi total trip with 1 bar remaining (4mi GOM, 18.6% SOC on the ELM327). So I had to stop in Thousand Oaks to charge for 1 hr to finish the 112 mi total trip. Odometer read 112 miles total when I got home. So here I am wishing that the LEAF had a little more range. I figured the FIT or the Spark with the extra range would allow me to make trips like this with less opportunity charging.

Spark EV has a 3.3kW charger and no DC quick charge capability yet.
Fit EV has no DC quick charge capability (in the USA; it does in Japan).

All three will need plenty of recharging to go 112 miles, and only the LEAF (of your three examples) has DC CHAdeMO quick charge capability with over 2500 installed worldwide. LEAF also has optional 6.6kW charger.

I thought I was going to be impressed by the Spark, as did the Chevy, Salesman. Definitely more impressed with the LEAF. I posted my review:

Also, is my car losing almost 4% capacity since last month typical? Maybe I should get the reprograming done?

You should definitely have the reprogramming done.

If you expect to drive 80+ miles between charges with any regularity you need a car with at least one of the following characteristics:

1. 100+ mi EV range (RAV4EV, Tesla Model S)
2. QC with suitable infrastructure (LEAF, though unfortunately there are none currently on the route of your recent trip)
3. 30A L2 charging (quite a few cars qualify)

Back on topic, my car is currently around:

19.5k miles, 2 years since delivery
58 Ah
 
53.5 AHr per LeafDD @19,500 miles.
I lost my first bar last month (May), but it seems as though I'm headed towards my second: am I wrong?
The "health" metric is @77%, which would also suggest I'm close to a second bar. However, I can get close to 70 miles @100% charge (and that's with some highway and A/C).

I left on my 112 mile trip with 100%. Did 4hrs of charging on the road, and it took another 5.5hrs to charge back to 100% when I got home. So a total of 9.5 hrs of L2 charging to achieve 112 miles with an overall efficiency of 4.1m/kwh. Although, on the way back I was driving 65-75mph on the fwy. (hence the drop from 4.8mi/kwh to 4.1mi/kwh)

Good stuff on the AH capacity. I started a running list on the 1st post with the results. This is good, because it tells me although it is alarming I had 64ah last month (which is excellent), my current 61.5 ah is still not out of align with some of the posted results.
 
6/22/13- 2nd bar loss.
Mileage- 48,918.
Ah- 51.48.
Owned 25.5 months.
Battery temperature has typically been 70F to ~90F for the last month.
Location is inland Los Angeles.

Wow! That's a big drop for just four months. Phoenix heat strikes again.

Yeah, it wasn't full capacity when I got it. Wish I had had the LB App and I may have waited for another one. When I checked it with the App in April, it was 63 AH (rounded).
 
Just got the Elm & Leaf battery app running yesterday. First measurements show 55.23 AHr and CAP at 83.36% on our car. It has 32,745 miles on it, going on 27 months in service. Lost the first bar about 500 miles ago. Never DCQC'd, usually 80% but more frequently going to 100% charging to make the range work for longer trips. Mild climate use, battery temps never over 6 bars in summer, 5 bars in winter. App put temps of the battery at 75-78F this morning. In the heat of the day they were 76-80F yesterday. I'm starting to log my changes now, for sure. Not looking forward to losing the second bar.

Amazing how we can lose a percentage or so in capacity within the same month and a few hundred miles. If you look at the trend, you definitely see it diminishing.
 
Date first bar lost: 22 June 2013
Miles: 28310
Temperature bars: 5 in winter, 6-7 in summer, never 8 or above
LeafDD temps: 27.7, 26.8, 26.7, 25.9
S 79.9008 C 54.7891 H 79.31
192 Gids @ 80%, 385.5V
226 Gids @ 100%, 394V

80% is standard, 100% 2 times/week, never QC'ed (yet)

Greg, how many miles are on your LEAF?

We just got a DCQC in Thousand Oaks (Ventura County)
Will be interesting to carefully track capacity before and after Quick Charging.
Its at the Rancho offramp (Transportation Center).

Perhaps someone knows the answer, but why do most of the Blink L2 stations cost $1.50-$2.00hr, and yet all the DCQC L3 stations I have seen are listed as no cost?
Not complaining, but it really doesn't make sense!

No offense, but what does posting this giant picture of a Blink charger have to do with recording "battery degradation data"? It makes it difficult to track results in this thread. :x

The Blink Plus L2 is $1/hr. and those other charges have been in force for a long time. However, the Blink QC fee of $5/charge is fairly recent so they may be having problems with the fee charge.
