Its not going to happen for the same reason you cant use the same battery from one Japanese made cell phone in another Japanese made cell phone,they want to sell battery's
On the other hand, every single LED flashlight I have now takes AAA batteries no matter the confuguretion. In the past it could be D, C, AA, AAA or lantern batteries. Another thing I've noticed is that many of my small devices use a CR2032 battery to power them or be used as backup (computers, clockradios, watches,...).

For the same reason that all the Automobile charging plugs are the same for all manufacturers eventually all the batteries will have to be the same in size and shape.( If replacement batteries becomes the norm)
Just like all gas nozzles fit all cars, all future batteries will fit all cars, that's the only way a large scale electric fleet can work.
Maybe some day we can have price wars in the battery changing stations?
The problem is that the different vehicles are going to have different power requirements.
A small vehicle will use a smaller capacity battery and a larger one will have a larger capacity.
Not all electric vehicle are going to be the same size or have the same power requirements regardless if the plug is the same and it may not be.
what if a larger vehicle takes 240V or 440V and not 110v?
who knows what is actually going to happen.
I don't see this happening until batteries shrink in size dramatically. Electric vehicles would have to be standardized for a specific battery size/shape/capacity. The "battery station" would have to have a sizable inventory of charged batteries ready for use. Lots of standardization has to occur so that batteries can be placed in and out of charging equipment without physically connecting cables.
And finally each station would need a siginficant upgrade in the electrical wiring to handle the recharging load.
Lithium batteries are already smaller and lighter. They could solve the issue of differences in power needs for different sized vehicles by simply having more or fewer batteris. They do not need to be different sized.
Evnetually the market will weed out companies that offer cars that run on different voltages, or use different types of batteries. People will just not buy them becasue they cannot get battery "refills".
Service stations will need to have a battery tower like a giant vending machine. Batteries will be stacked up mayber 50 rows high and 20 wide. As one battery gets charged, it will be dropped down to the vendor position and available for hte next person. The old battery gets deposited, tested and sent up for charging. If it will no longer take a charge, you pay a replacement premium.
That part is really pretty simple as is standardiing batteries and making them changable. The hard part will be getting the power to the stations for recharging. The other difficulty will be the need to change out more than one battery. If a car has 40 batteries, it would take a while to fill up with 40 new ones. Eventually they will get more power out of smaller batteries and this will be easier. Another option is to simply replace 5-10 of the batteries (or 3-4 if they are larger) and get enough power to get to your destination for a recharge.
UNtil batteries get smaller, the tray idea for quick change is a pretty good idea. Icing will not be a problem because as batteries discharge they generate a great deal of heat. (Try working a laptpop while wearing shorts smoetimes, it can burn your legs with some computers).
It could take a while to get all of the ocmpanies on board and standardize batteries and swapping systems. You would think common sense woudl get them to do it, but lookat cell phone chargers and accessories. Theey maybe down to two or three types (micro USB and Apple's two different types), but still millions of each type need tobe made and they are not interchangable. It makes no sense, but profits keep driving them to produce different chargers/connectors. It make take a Federal mandate and/or treaty agreements to force them to standardize.
The big difference between Gas and electric vehicles is that all electric vehicles will be able to be charged while when not in use at home. This will mean that you will only have to change batteries for extend trips.
Anybody who owns an electric golf cart already knows the drill.
Wallmart sized battery changing stations might be the thing of the future on the interstate but not so much in your neighborhood.
You make some very good points.
and I didn't give the reaction in the battery from discharging any thought.
BUT
I don't use my computer out side in -10*f or lower temps.
Batteries loose power when they get cold or freeze.
A week battery will not generate as much heat as it is depleted.

The most promising tech I heard of in this regard was building a hybrid battery/capacitor. Essentially a battery that could charge rapidly like a capacitor, but then hold that charge and release it over time like a traditional battery. This would mean that charging of electric cars could be done in about the same time it takes to fill a tank with gas. Also, you would only need a standard plug, not what would basically have to be a standard car design.
