That is what I thought. Guessing GM put a cap of 90% on this car to keep a good battery life? Should I just leave it plugged in when ever I am not driving then? Also by charging with every night with the charger that it came with unless I need to use the tier 2 or would tier 2 always be okay?JPL wrote: ↑Sun Sep 01, 2019 2:35 pmCharge every night with the charger that came with your car.
Yes is better to park it under a roof, like in a garage.
If you are not going to use it for months keep it to a 60%
If it gets too hot or too cold GM advice to keep it plug in.
It is kind of difficult as is very fun to floor it but to maximize battery consumption avoid to run.
Also drive always on L
Thanks for this. Last questions I could not seem to find or I am not wording it correctly. I have the battery to charge at 7pm with the off peak settings. Before 7pm (not charging) and it is plugged in does it cool or heat the battery with battery power or the charger? I also got the Volt PIDS in torque working and found Usable and Raw SOC. After today's drive I played with this as raw was at 40% (which is what the car was reporting too) and usable was around 29%. Does this mean I got 11% degeneration on a 3.7k mile EV or should I see what this reads at a 100% charge?SparkE wrote: ↑Sun Sep 01, 2019 9:56 pmI would suggest reading these threads :

There are lots of opinions about battery life expressed. Personally, I don't charge to 100% unless I need the range - I generally charge to 75-85%.
BUT, I don't live in an area where it freezes or gets really, really hot (often), so the battery 'conditioning' isn't necessary so I don't leave it plugged in.

I agree! I have been fortunate to have driven every model year of the Spark EV for at least 3 years. I started with a leased 2015 followed by purchases of a used 2014 and a used 2016 - both of which I still own. All three vehicles have exhibited about equal amounts of battery degradation. I am interested in what charging protocol is being followed by those Spark EV owners who have 75K+ miles on the ODO. At that mileage, they have had many more charging sessions than most of us.JAMMan wrote: ↑Tue Sep 03, 2019 6:34 amThere have been literally thousands of posts with individuals producing long history and studies of battery data to support their conclusions on the battery degradation over time, use and charging.
Honestly though? It's all pretty inconclusive. I haven't seen any hard evidence that charging to 100% every day is bad. I haven't seen hard evidence that DCFC (DC Fast charging) is detrimental to the battery pack. I've NEVER seen an instance of Chevrolet replacing a battery pack due to being significantly degraded.
All this to say my personal philosophy is: Use it however you want. I don't get wrapped up in making sure it never goes above 80% or below 30% or plug and unplug throughout the day to maintain the ideal 80% range, or any number of tactics many have used. I charge on 120V, 240V or DCFC at any point is convenient to me. I just did a 80 mile trip to my in-laws this weekend using a DCFC along the way for 10 minutes to boost my battery range for interstate travel and my range is reporting the same it does every day.
Chevrolet warranties the propulsion system (battery, and electric motor) for 8 years or 100k miles. Are you likely to own this vehicle past that? If not, I wouldn't worry about babying the system.
Lastly, 100% 'reported' battery charge is NOT the same as 100% of the actual capacity of the battery. They do not allow full use of every kW of battery capacity, they build in a buffer for battery protection and, you guessed it, degradation. Tesla does the same thing. So even if YOU charge it up to 100% it is typically closer to the actual 85-90% optimal charge spot of the battery pack.
I think, a lot of people apply the same logic we've learned about consumer electric battery powered devices like smart phones and laptops to these commercial-grade automotive batteries because they are both lithium based but that is FALLACY. The two are similar but very different in a LOT of ways especially in chemical construction. The battery cycle and usage of smart phone batteries is so different than EV's, it's not like you should expect it to perform half as well after a few years.
