There are significant logistics here. How many batteries should be stocked in any one place.
Batteries are large. So you’re also talking about a lot of space.
At the same time you still need to build out the electric capacity to charge those batteries.
The number of batteries you would need would need to be some multiple of the actual number of cars sold. So if there are 300 cars sold, you probably need something like 1200-1500 batteries in the same city just so a car doesn’t have to travel unreasonable distances to do a swap.
The multiple is probably higher and it gets much worse spread out over the entire country/world. Thats burdening each car sale with multiples costs of the most expensive component in the car.
It’s mechanical, so there are likely to be more breakdowns and other issues.
Battery replacement requires changing the car design and leads to a design that’s almost certainly much less protected from the elements or requires the addition of expensive protection, both in terms of the cost of the additional protection and the weight of the protection.
People tend to treat replaceable batteries poorly.
Battery replacement is just not a good choice relative to the much simpler ability to pump in electricity.
