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.
