If your Spark EV is a 2014 then you have an LFP lithium iron phosphate battery pack or more accurately it has a lithium iron nanophosphate battery pack.  The 2014 Spark EV must be charged to 100% once a week or the computer will have a hard time predicting how far the car can go.


The good news about having an LFP battery pack is they can last twice as long than NMC batteries which the 2015 and 2016 have.  LFP can be charged to 100% daily without damaging the battery and can take multiple DC Fast Charging sessions without suffering damage.  One downside is they are more affected by colder temperatures than NMC batteries.  I have seen a drop in range with temperatures starting in the low 60s.  LFP also don't hold as much energy per pound and volume as NMC batteries.  To keep the range the same in the 2015 and 2016 Spark EVs Chevy just made the battery packs a little smaller.


My 2014 Spark EV has lost about 3 miles of rage from the original 82 mile range.  Of course only driving about twice a week helps and I only charge my EV to 70% because it is bad for the battery to leave any EV sitting fully charged for days.


Oh, almost forgot.  Check your tire pressure.  You be surprised how much range you lose even with just a few pounds under pressure.  Also if you just got new tires and didn't get the same kind of tires that were on the car originally that can make a huge difference.  Tires made for EVs have lower rolling resistance to increase range.  Putting on tires not made for EVs have more rolling resistance and thus you will lose range.
