I think of a cycle as “drain and charge.” So, if you drive 50 miles a day and charge overnight, I see that as a “Cycle.”
Frankly, I think the future is in something more like a graphene capacitor.
That would sure present an issue with memory.
But for those trying to advance the idea I would see them as focusing on their best options, they need to get funding ... then they can go for realism on how real consumers will recharge.
