OP: if you are charging to 100% SoC in the summer, I suggest you charge in the early AM hours so that the car does not sit at 100% for long, and the battery has had a while to cool off.
My wife would also charge to 100% every day if I did not object. I remind her that she has never driven more than 40 miles in a day since we brought the LEAF home in Jan 2017, and should the impossible happen she can always stop for a charge. One of the advantages of being retired and not having children in the back seat.
