Thanks for the info. For reasons that I do not understand, 2015 Spark EVs seem to have a battery capacity around 15 kWh at ~30k miles on the ODO. Yours would be number 4 that I have seen reported.TheLondonBroiler wrote:I also used the Bolt .csv file, that a user (beachbum) provided the link for, in this forum. I initially tried to be a cheap a$$, and use torque lite (free), but I couldn't load individual pids or the whole .csv file. Torque Pro is the first app I've ever purchased. It works well enough, an excellent value for $5. Battery capacity is only displayed to the tenth of a kwh (ex: 15.1 kwh) in a widget, however, when viewing the pid selector screen, it gives a value to a ten thousandth (edit: It's really a measure of about 1/30th of a kwh).
My battery, according to Torque, has gradually gone from 15.4kwh capacity to 15.1kwh, in just this month. I think between charging to 100% everyday, "full use of" acceleration, frequent fast charging, and hot temperatures, my Spark isn't being babied, while not being used in a manner that is outside the terms of the warranty.
I may have to press my employer a bit harder for a 110v outlet, so that I don't have daily range anxiety this winter (and likely degrade the battery worse in the process).
But... the way you drive the car will impact your GOM range. I typically drive mostly around town, in L and around 40-50 mph. So, it is not unusual to see my miles / kWh run between 6 to 7. At 6 mi/kWh and at 15 kWh HV battery capacity, I would still get a full charge range of 80 miles. This is more than enough daily range for my needs. A friend of mine, who just turned in his leased 2015, had a battery capacity of 14.8 kWh. However, his driving to and from work was mostly on the freeway at 70 mph and the reduced battery capacity gave him range anxiety.
