Imagine buying a brand-new EV, where the battery is 3/4 the cost of the vehicle. Then you do this "battery swap" and get a *used* battery pack that's been god knows where.
You REALLY can't think of a way for this happen reasonably? Seriously?
Look, I apologize for the derisive response. It is not helpful.
You appear to be fixated on "owning" the battery. That is fine, you can keep your ultra special brand spanking new battery and even pay to have it recycled and replaced. You are not required to exchange it. You can keep recharging it all that you want... until it dies. Then, you can buy another brand spanking new battery for full price while also paying the disposal price for the now-old and used battery.
Or, you can start out with one of the "battery time" batteries that are made to be swapped out. You only pay for the first battery, but you don't have to pay for disposal or for a "new" battery. You only pay for the electricity used with a small fee on top to cover the eventual recycling of the batteries over time.
So you get to work with your toddler style ownership if you want, but I am betting that eventually, most everyone will choose the swappable batteries as the costs of recycling and repurchasing becomes too much for the average person to want to deal with. The capital costs are killer to own rather than swapping in a system.
In China, there are moped style scooters with swappable batteries. There is a vending machine where you put your uncharged batteries in and pull out charged batteries. The batteries are recycled once they fail to charge over 90% (I don't recall the exact number).
Who cares if the battery case is scuffed as it is never seen except when exchanging.
