Most EVs can now do 200 plus miles on a full charge so I really don't think range extenders are that necessary (especially when combined with level 3 fast charging). Plus where would you put it? The batteries on an EVs are stored on the undercarriage and they pretty much take up the entirety of the undercarriage, if there was extra space left over you would just put a permanent battery in there.
The batteries are what make EVs heavier compared to ICE vehicles, and the majority of trips don’t call for anything close to their peak range.
Installing a fraction of the capacity as a static battery would reduce weight for shorter trips, also extending the typical range.
Removable batteries could be installed in a standard cavity in the undercarriage, or in the regular cargo space, it just needs an electrical connection to the rest of the system.
Fast charging is also a problem, as it disproportionately affects the performance and longevity of the batteries. Swapping batteries would permit charging them at a more leisurely and manageable rate.
You have to account for all of the additional hardware that is required to enable swapping of batteries. Have you ever picked up an EV battery they are incredibly heavy and huge. I really can't see how you would do it without using the kind of engine lifting equipment that mechanics have.
I can't see it as practical or safe to allow general members of the public to use them. Even if you can pick them up, which you can just about do, you would seriously risk injuring your back.
