It really depends on the battery chemistry of the specific EV, how many watts you charge at, and deep cycle vs. shallow cycle. Not all EV batteries will hold up to that many charge-discharge cycles.

Even at that, 100,000 cycles is an exaggeration. From what I can tell, you can expect up to 3000 cycles from Nickel Manganese Cobalt batteries before they hit 80% of original capacity. Lithium Iron Phosphate batteries can last for 10,000 cycles before dropping to 80% of original capacity.
