Chevy Spark Battery Degradation

Chevy spark battery degradation. Mine has lost more than 15 in eighteen months and 17k miles. My chevy bolt ev just passed 100 000 miles so let s look at how much capacity. Since june 10 i have used torquepro and an obdlink mx adapter to measure the battery capacity in my 2016 spark ev. 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.

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. That would suggest that warranty replacement could occur when the a123 battery degraded to 14 3 kw within eight years and 100 000 miles. With spark you know how much your battery has degraded.

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. I can only imagine we have our legal brethren to thank for this. Then to my surprise last month it went up to 15 9. Had a 22kw a123 battery and the 2014 s warranty calls for warranty coverage at 65.

Chevy bolt ev battery health after 100 000 miles all electric vehicle batteries degrade and lose capacity over time.
