I've been playing with Torque Litr (basic/free version) for just over a year. Thank you BeachBum for sharing the pid list. This will only work with pro, which I bought today ($5 is a deal). Here's my initial setup: (Long form voltage readings are to the ten thousandth of a volt and ask 96 pairs are within a hundredth of a volt of each other...damn impressive)

I agree! I use TorquePro, an OBDLink MX Bluetooth adapter and an old Nexus 7 tablet running Android 5.1.1. Works great for both my 2014 and 2016 Spark EV. However, the PIDs I use are for a Chevy Bolt which has 96 cells. This works fine for the 2015 and 2016 Spark EVs which also have 96 cells. The 2014 Spark EV has 112 cells but only 96 show up. Still, this is not a problem as I use the average cell voltage for my calculations.

I just looked through the cell voltage Parameter IDs and I wouldn't be surprised, that if you continued the pattern, that you would get the voltage read outs.

I saw that too and extending the pattern in the CSV file should not be a problem. I might give it a try by adding the remaining 16 cells. It probably would be wise to give the file a separate ID so as not to screw up the file for the 2015 and 2016 Spark EVs.


Update: I added the additional cells to the PID list, saved it under a different file name and added it to the extendedpids file in my Nexus 7. Then I updated my TorquePro display pages and added displays for the additional 16 cells (Cell 97 - Cell 112). When I tried the new file on my 2014 Spark EV, all 112 cell voltages were displayed but I lost my display values for Battery Capacity and Battery Temperature. If I use my original PID file on the 2014 Spark EV, everything works fine and the extra cell displays do not show any values. I can use the original PID file to monitor both cars and the revised file to monitor all cell voltages in the 2014 Spark EV. This will work for me.

I just took my 2015 SPARK EV in for the battery capacity test. The dealer had no idea. After 3 days I got them to call their tech assistance and they had them pull a file via the OBDII. I should get my results next week.
On my Energy Details screen I would see on 13 kWh before it went into low power at about 6 miles left.
I always get 80-90 mile range because I hypermile and get 6+ Mi/kWh all the time.

60% (warranty threshold) of 18kwh (usable capacity) = 10.8kwh. If you're not below that and not experiencing any problems, I believe you're wasting the dealership's time. If they offer you a free battery, let them know I have a bridge I want to sell them.

80-90 mile range at 6 mi/kwh = 13.3 kWh - 15 kWh. I would suggest you find someone who has TorquePro running the Chevy Bolt .csv PID file and an OBD2 adapter and have them measure your battery capacity in order to get a more accurate measurement.

My leased 2015 Spark EV with 28K miles on the ODO was reading about 15.5 -16 kWh (Energy Screen calculations) just before I turned it in (I did not have TorquePro then). A note here - A few months prior to turning in my 2015 Spark EV, I experienced a sudden loss of ~1.5 kWh in battery capacity. Prior to the loss, my 2015 Spark EV battery capacity was running between 17 - 17.5 kWh. Unfortunately, I did not have Torque Pro then.

A friend of mine, who also had a 2015 Spark EV, had a TorquePro measured battery capacity of 14.8 kWh at about 30k miles on the ODO. For reference, my 2014 Spark EV with 15k miles on the ODO, currently has a TorquePro measured battery capacity of 17.0 kWh. My 2016 Spark EV with 12K on the ODO, currently has a TorquePro measured battery capacity of 16.8 kWh. When outside temperatures range in the 70s and 80s, I usually have a full-charge GOM range of ~100 miles for both cars. Most of my driving is in town and I always drive in L for maximum regeneration.

On TorquePro's website they say it will run on any android platform and show it running on a Nexus S. Beyond that I have no idea. Always been an android guy, not a Mac person. My phone is a Galaxy 7 Edge. If your Nexus won't run it you can always get an Android tablet to run it on.


Any known solutions for iPhone users?

Using the GOM and battery usage estimates, my 2014 spark EV seems to have dropped to 15.7kWh capacity with about 30k on the odometer. Full charge GOM is now around 78.

Mines was around 15.5 to 16.5 depending on temperature (15.5 in early part of the year, but it went back to 16+ by summer). GOM isn't really a accurate way to measure capacity compared to the energy used and percentage. As my job shifted from a 14 mile round trip to a 60 mile round trip near the beginning of the year, I was getting into yellow regularly and occasionally to 90%+ usage so I had a good grasp of my capacity.

Also I checked my manual for warranty, for the 2014 spark, it was warrantied to about 70% of original capacity which meant once it started reaching 13.4 kWh, you might have a claim. If I had kept my Spark, I would probably be able to claim warranty near the end of the 8 year term since my car was probably among the last 2014's sold (4/30/15).
