I read this in the manual but no explanation was provided? What is the reasoning behind keeping the car plugged in after a full charge is reached?
It is probably a good idea to plug in when you park in the hot garage in the summertime. However, based on my experience with my 2017 Volt, the lithium battery pack will take 8-9 hours to reach ambient temperature. By then the garage will have cooled off some so the AC may not run at all overnight or only briefly.I live in scorching hot AZ and park my ELR in our garage. At times it can get as hot as 120 degrees in there. Hypothetical scenario and question:
I charge my ELR the night before leaving to work.
I leave to work with a full charge.
I return home from work with 70% charge remaining.
Temperature outside garage is 110 degrees; inside 120.
Should I still charge my car at 70% due to the heat?
Currently I don't plug in my ELR until I'm almost or at 0%. But I'm learning more about the other benefits of charging daily.
