Chevy spark battery degradation.
With spark you know how much your battery has degraded.
I can only imagine we have our legal brethren to thank for this.
My chevy bolt ev just passed 100 000 miles so let s look at how much capacity.
There is a feature on the spark where you can figure out quite easily how much your battery has deteriorated over time travel.
And just this week it went up again to 16 0.
So i just finished compiling my historical data and calculating my battery degradation after 70 000 miles of driving.
It s a bit higher than i thought it would be but i did notice an immediate and significant drop off immediately following the software update.
Had a 22kw a123 battery and the 2014 s warranty calls for warranty coverage at 65.
Then to my surprise last month it went up to 15 9.
Chevy bolt ev battery health after 100 000 miles all electric vehicle batteries degrade and lose capacity over time.
Since june 10 i have used torquepro and an obdlink mx adapter to measure the battery capacity in my 2016 spark ev.
That would suggest that warranty replacement could occur when the a123 battery degraded to 14 3 kw within eight years and 100 000 miles.
If 17 4 is the usable capacity then losing 1 3 kwh from a battery in a spark sold over 3 years ago really shouldn t be frowned upon.
