Re: Commuting 160 miles in a Spark EV

This means you could be loosing between 1 an 5.7 kWh or battery capacity per year, which would translate to loosing 6.6 miles or up to 37 miles of range per year. Thanks for the reply. I’m very concerned about long term degradation and it’s effect on her ability to continue this drive long term. I’...

Re: Questions and Data tracking

The loss of capacity on our 2014 is a straight downward line that shows no sign of slowing down. Over the last two years, it has been declining 0.15 kWh per 1,000 miles going from 15.8 kWh at 52,000 miles, down to 13.7 kWh at 66,000 miles. If I assume a nominal usable capacity of 19 kWh that means ...

Re: Questions and Data tracking

Data from this month's 100% charge (May.) Previous Charge to 100% was 108 miles. This charge to 100% and the GOM is at 107 miles. Previous Charge to 100% kWh was 16.2000. This charge to 100% and the kWh went back down to 16.03333 kWh (odometer is at 13,692). The average was 6.9 mi/kWh this past mon...

Re: Battery degredation

The one thing I have really appreciated on this forum is the availability of help and constructive comments that many Spark EV drivers have contributed to our individual EV learning curves. I am in my 5th year of driving a Spark EV and I still have so much to learn. Please keep up the good work and ...

Re: Battery degredation

In reading this topic, I saw that the 2014 Spark EV had a 22kw A123 battery and the 2014's warranty calls for warranty coverage at 65%. That would suggest that warranty replacement could occur when the A123 battery degraded to 14.3 KW within eight years and 100,000 miles. First the 2014 Spark total...

Re: Battery degredation

A little off topic perhaps...I had been charging to 92-94 miles at 8 ohms on my home EVSE. Last week I checked to see if there were any outstanding recalls on my car and come to find out the Powertrain Control Module 2 needed reprogramming to correct the range estimation. So, the last 2 charges net...

Re: Battery degredation

My warranty booklet says 35%, hopefully that's not a typo. Any chance you'd post a picture of the front of your warranty manual and where it says 35%? I can not for the life of me find any specific battery degradation warranty info on the web regarding the 2015, and I bought mine second hand (no ma...

Re: Considering a cheap Spark

What year? I might be a bit concerned if it was a 2015 due to possible electrical issues some drivers have experienced - myself included. What were/are these electrical issues? How much hassle to get it repaired? You will find posts on this forum. Usually the yellow Service Vehicle Soon light will ...

Re: Commuting 160 miles in a Spark EV

With that in mind, know that driving with the cruise at 55 is probably not the most efficient, nor fastest, way to get there. You'd do better in both time and energy usage to follow (at a reasonable distance - no need to tailgate) a big rig going 60-65. What I'd do is get on the highway, set the cr...

Re: Battery degredation

I really find this interesting. Do you charge to 100% each time you charge and what type of charging do you mainly use - L1, L2 or DCFC? So far, the HV battery degradation rate in my 2016 Spark EV is about 1 kWh every 4000 miles. You lost 1.1 kWh in 4200 miles which equates to 1.02 kWh per 4000 mil...
