I have read that using the fast charger will degrade the battery. Is that true?
Using a fast charger constantly will speed up battery degradation a bit, but many owners in condos and apartments have little choice.
The good news is that, as data has accumulated from the field over the past 10 years, battery degradation in most models has been less that predicted. There are reports of cars (mainly Teslas) in service in Europe as taxis that use fast chargers daily and still have 70% of their original pack capacity after 150,000 and more miles.
My recommendation would be that, if you have the ability to install a Level 2 charger at your home, you should do that. Just plug the car in every time you get home, set the charge limit no higher than 80% unless you're about to leave on a long trip, and you'll never have to worry about its state of charge, what you might be doing to the battery, or finding a line at the local charging station. You'll probably also pay less for the electricity.
