Or you could just use the next bar down for a 58% setting. I'm not sure why you would want to charge a car that gets used regularly to less than 2/3 though. You are significantly reducing your margin for unexpected trips, and there isn't much additional improvement to battery life to be made, is there?
Actually VERY shallow cycling does prove to work better. The vaunted Prius pack was diff chemistry but mechanics are similar. That pack cycled from 40 to 80% as much as several dozen times a day.
Li voltage is different so it prefers 50%. So 40-60% is good. I tend to run between 25 to 70%. Is it limiting? I don't really see that. The range covers my entire commute for my 4 day work week. Roughly 110 miles. In fact, I just did this this week, starting at 71% and ending at 22% during colder than normal weather so I even used heat. It worked. For the most part, I am only QCing twice a week.
Now it will change when my free charging runs out but not dramatically so. I plan to likely charge to around 65% for the start of the work week then plug in for 85 minutes every morning. I should end the week around 40%.
This allows plenty of cushion for random side trips if needed. I look at the 25% lower end of my SOC range as all buffer. That's another 65-70 miles added to whatever my SOC happens to be. For longer trips than that, they would be known in advance.
Having looked at unexpected trips I have done and there are several but in town stuff. Picking up kid from school, etc. Small stuff. Seatac is the only destination that comes to mind having had to pick someone up last minute twice this past Summer but they now have DCFC in the cellphone lot so I only need the 52 miles of range it takes to get there. I am more than covered.
