Battery trailers might be a good idea. A charger station will have a bunch of trailers with different size batteries for rent. If you need to get somewhere fast and don't want to wait to recharge, or if you want to go on a long trip, you can rent one. To be honest, this just logically leads to hotswapping car batteries. If a car manufacturer was able to make their batteries quickly hot swappable and then sell spares to gas stations (who could have large charging racks) then you could solve the charging time problem nicely.

Seems silly. How long of a trip do you think you'll need to take where driving extra distance to the local battery/trailer repo, hooking up the hitch, and the power cables ... for your make/model... waiting in line/signing paperwork. Of course you have to drive extra and more time for dropping it off. I drove nearly half way across the USA (1200 miles) in an EV, it's just not a big deal. Sure it took 21 hours instead of 19 or some such, not a big deal unless you do it often. I save many more hours with avoiding trips to the gas station, smog testing, oil changes, and related.
