However some experts still recommend you don't, limit charge to 95% (and they give technical facts to back it up). The advice to not leave battery at 100% for extended time is still valid I assume.
Does anybody have any clever idea on how to do charge to 95%. I know you can use the charge timer to limit the amount of time you charge, but calculating the exact time to shut it off is kind of tricky. I've tried it a couple times to reduce charging time. Apparently not enough, it ends up at 100% anyway. Is there some way to set shut off at 95%? Is there a time to charge chart based on temperature and starting charge to get to 95%?
You can do this but it will take some work on your part due to differences in home EVSEs.
*Check estimated charge time for your EVSE (you will have both slow and fast L2 times listed)
*set end timer to 3 hours AFTER you plan to be up the next day.
*next day (or whenever) get up check SOC.
record all this data over a few days.
Analyze data. You will likely find that it becomes easy to hit your target SOC within a 5-10% delta. (charge times jump in 15 min increments at times)
what you need to look for;
Making sure you check your charge before it gets to balancing stage. This is why I recommend 3 hours. I would be specific but cannot because your EVSE is different than mine.
Yes, this requires setting end time for charging EVERY NIGHT.
Finally; why 95%. The general consensus is 90% based on Bolt, Tesla, etc.
FYI; your best bet is running your car at lowest SOC that covers your needs. This grows in importance with the Mercury. When cold (if it gets cold for you) the issue is pretty small and range is reduced in Winter so charging to full is a not the "best" option but also not significantly bad either. Its better to play it safe than be stranded in life threatening weather
