Think of an oil change setup, with shops stocking the most common batteries.  Machines swapping them out, so weight isn't an issue.

It's feasible, unless you let your distaste for the messenger of the idea cloud your judgement.

Not gonna happen in passenger vehicles. The battery packs are a stressed member of the frame in order to improve rigidity. Making them a removable item means that you have to massively bulk up the frame of the vehicle to reach the same rigidity, increasing vehicle weight and decreasing efficiency. It likely means that you also have to build a much more durable frame for the battery to have it withstand repeated insertion and removal. Again more weight, and less efficiency. All that increased weight means more load on tires, more load on drivetrain, more load on the road. It's one thing to do it in a cordless drill, it's another to do it in a multi-ton vehicle. And this is largely unnecessary in a world where most EV owners charge at home and it's only the rare exception that they need to figure it out for a road trip.

It's not a weight problem at the "fill station" per se; it's an engineering trade-off that is unnecessary and unwise to make. Charging infrastructure is the answer, not battery swaps.

I haven't really looked at it closely when you think about vehicles like long-haul trucks, though. The battery and frame weight of the tractor on an electric 18-wheeler compared to the overall combined weight of a full trailer load, along with the much bigger size of a tractor, may make it viable there. Especially since those trucks make money when they're rolling, not when they're charging. What you give up in efficiency may be regained in what you can actually earn per day.

But it doesn't make sense in a typical passenger car.

yup, batteries "could" become much smaller and lighter in the future

heck, some folks thought gasoline burning passenger cars would be around forever

The battery swap concept has been examined and even tried, and it's simply not a good option, for various reasons noted.  Nobody is seriously looking at it today.

The inductive charging concept has more "legs" at this point.

Upside Down: Study Finds Evs Cost More to Drive Than Gas-Powered

What has turned the EV world upside down is a report by Anderson Economic Group or AEG. It found that mid-priced electric cars cost more to run than similar gas-powered cars. However, this doesn’t apply to luxury EVs and ICE vehicles.

Based on current prices, internal combustion cars need $11.29 of gas for every 100 miles driven. For electric, that goes up to $11.60. That’s if they charge their EV at home. For those that need to frequent charging stations, that number jumps up to $14.40.
