02/04/21 19031 14.47000 78
03/02/21 19208 14.50000 79

This shows a -1.3kWh capacity loss over 1,561 miles when comparing March 2021 to March 2020
As apposed to 2019-2020 -0.47 kWh capacity loss over 5,183 miles.

The capacity hit an all time low on 2/21 at 14.43 kWh but bounced back after running it down low and charging it again.
Weather is getting nicer and the drive to work is in the 7 mile/kwh range.

I advanced the clock to daylight saving time today because I got tired of waiting for it to happen automatically. I expect the range to increase as I get more into a normal driving pattern.

The capacity is creeping back up a bit.
We have a level 2 charger installed now so I find myself topping it off about once a week now.
I did hit a range of 100 on March 18th but it fell in the middle of the month so I won't use that as a data point.
Since 3/02/21 I have averaged 6.9mi/kWh

'17 Bolt Premier w/ It All! 59k miles.
GM needs Modern Troubleshooting tools for Modern EV's.
3 step Trouble Tree, 1st try, nope, 2nd try / cost $800. 3rd try fixed it.

Capacity is up some from the sudden low in November, and range is definitely up. Our local Chevy dealer got a couple of Bolts in this month, and we went down to sit in one. Definitely tempting, but I'm going to wait until the EUV is out before making a decision.

For just over 3 years I have been using Torque Pro to track the HV battery degradation for my 2014 and 2016 Spark EVs. This is what I I have been seeing:

2014 Spark EV (w/o DCFC): degraded 1 kWh every 4400 miles. Average of 5.58 miles per Kwh.
2016 Spark EV (with DCFC): degraded 1 kWh every 9224 miles. Average of 6.03 miles per kWh.

7473 miles / 1.86 kWh drop in capacity = 1 kWh drop in capacity every 4017 miles. What model year of Spark EV do you have?

I had hoped for a continued increase in range from the 14.4 kWh. It seems like the capacity calculated from the energy display numbers has been closer to 15 kWh, but I haven't really tried to catch the numbers just as they roll over to the next value.
