"X cents per charge cycle" is a bit simpler than the reality. The actual wear cost of charging/discharging a big EV battery is cheaper in the middle and more expensive at the extremes.

I already have to own a car for short trips most days and an occasional long trip. And when I'm not going on a long trip I have a lot of extra battery capacity that I can rent to the grid at extremely low (additional) cost to me.

A dedicated battery storage facility on the other hand has to justify the entire price of the battery.

I took their numbers only as a simplified illustrative example to teach the idea.

A real deployed algorithm would estimate the "degradation cost curve" over the entire DoD, and stop charging when total (fully-considered) costs exceed revenue.
