I, myself, rarely charge past 85%. And I don't charge when it is hot. During the summer, I used to plug in the Spark in the early morning when I get up, when the pack is at its coolest. Now, I use departure timing, and have it set to me leaving (being at 100%) at 10:30 in the morning, so all I have to do is unplug it around 9 a.m. I don't know if it has done any good or not, but it is free to simply pay attention and it takes maybe 30 seconds in the morning. And I still have over 15 kWh in the battery.TheLondonBroiler wrote: ↑Wed Dec 02, 2020 9:56 pmPretty much par for the course. Time and usage both appear to be merciless at removing capacity from Spark battery packs. We all charge to 100% for the most part, and that impacts cycle life. This only snowballs as you have less range, you need to charge to a higher SOC, furthering the problem. Text book definition of a vicious cycle.
But then, I rarely drive it over 40 miles in a day, so I can do that. When I *know* I am going to drive over 50 miles, it charges overnight to 100%. Probably once every 2-3 months in normal times - not once since April of this year.
