How does one go about checking the life left in the high voltage batteries,, Thanks in advance
NORTON said:An easy way, without getting into OBD2 and apps, is to do a test drive of over 50 miles and be sure the battery is fully charged at the start.
Check the 'Energy Usage' page to be sure.
You want your drive to use at least 50% of the capacity to make the results more accurate.
Check the page again at the end.
You're looking for kWh used and the percentage of charge.
Run the math.
2014 Spark EV had a slightly higher rating than the following years due to changing the cell supplier.
Somehow the EPA rating remained the same....
'14 was ~19kWh
'15 and '16 was slightly less.
Bolts don't give you that number directly on the screen, so it's easy on the Spark.
You can find lots of info on this forum about typical kWh numbers for used Spark EV's.
I haven't logged my numbers in a while, but my '14 is doing great at 97k miles.
It still displays ~73 miles of range on the GOM. But the GOM uses driving history. My usage is usually 80% ~70 mph driving with the AC on.
Good luck. Post your results. Hope it's a bargain Spark EV because the 8 year warranty is coming up.....
RSC said:Sixty miles is pretty low and I'd be concerned, but this could just be recent driving history. Factors leading to a low estimate could include a lot of climate control, or starting out at the top of a hill, then driving back.
Better to follow NORTON's procedure. Even if you can't drive far enough to get the battery as low as recommended, you will get a better idea of battery capacity than by looking only at miles available after a charge. You do have to make sure the battery is fully charged before starting out, though. That's a must.
Edit:
But if the range easily covers your needs with some allowance for future degradation, I would say there is no problem.
