I got my 2018 in September, so I haven't had many charge sessions, but I try to limit my Level 2 charges at home. I have been testing the limits on the battery, to see how low I can safely go before charging it over night. I haven't been driving much, since I started working from home, so I haven't needed to charge much.
However, while on the road, I try to check out local Level 2 chargers to see how to use them, how fast they charge, etc. I typically limit my stay on these chargers to 1 hour; so far I've hit 4 of them, each on a separate day. I expect to explore more.
The Nissan manual says to limit the amount of CHAdeMO quick charges, since they can stress the battery if performed too often. I don't see a need for quick charges unless I do long distance driving. I rarely do long distance driving.
From what I have read about Li-ion batteries, their ideal operation is at 20 - 80% capacity, which is why many people try to limit the charge on their EVs to 80%. However, I have seen graphs from studies that show operation at 10 - 90% capacity does not take much life away from a battery, so that is the range I typically aim for on my phone and EV. BatteryUniversity.com is a good site for more info.
Also, the car's charge timer "Home" feature was mentioned in a reply post. That "Home" feature is only available in Leaf trims with Navigation. Mine is the Leaf S trim, so I don't Navigation or that "Home" feature. I use the charge timer, though, and hitting the override button is simple enough, since it is located next to the charge port lid button.
