Im reading about an NPR story about battery pack swapping? IMHO it will NEVER be done, or will any manufacture be willing to swap techno secrets with another manufacture . the battery packs would have to be made to fit every EV being built, and that aint going to happen. These guys cant even agree on how to fasten a plastic bumper and you want them to agree on a common battery pack????

The Only reason a fork lift battery works so well is thats its a CUBE, and the machines counter weight, they make them heavy and a CUBE to fit the machine, If its a pallet loader then its a rectangle shaped box,,and also the counter weight ,, Here it is, A 5,000 LB fork lift weighs 5,000 lbs and has to pick up 5,000 lbs, so a combined weight of 10,000Lbs . I got my start in this business working on electric fork lifts in 72 when I got out of the Army, its always been this way. and the charger is like a Fridge , and mostly running on 220 ,3 ph, or 440 3 ph.

Again, I dought very much any car company will want to see a quick change battery pack for a company built car.. to much liabilities to worry about ,,and Ford will never work with GM or Toyota or Nissan, or Honda. forgetabout it, it aint going to happen . When you finally get hit behind the head with the reality board , you wake up and see it for what its worth.. I say 90 % of these guys out there with this NEW QUICK FIX are looking for investors ,quick money,,a scam,,call it what you want. Things dont work the way YOU want them to, they work the way MONEY wants them to work . But its good to dream ,,kills time

The automotive industry may have to accept what they don,t want just like
they had to accept milelage standards, tire standards, polution
standards,lighting standards,safety standards,bumper standards,window and
windshield standards,seatbelt standards, fuel tank standards, seat
standards, door standards,roof standars,voltage standards and many more
standards dictated by the government all of which were forced on them.

Tire Standards are being quoted often here lately as an example of
"standardization acceptance" by the Major Automobile Manufacturers. However
it seems to me that there are a lot of "Standard sizes!" In Example a tire
labeling is standardized by the Tire Industry ; a typical tire is a " 205
(MM width) 60 (% Ratio height to width ) R (Radial cord construction) 14
(Inches of rim diameter.)" So the rim might be 12,13,14,15,16,16 1/2,18,20,
22.24.....or larger for trucks. and an American sedan width may be: 135,
155, 165, 185, 205, 215, 225, 235, or more ! The tire may be 78%, 70% 65%,
60%, 40%, Or perhaps 25% or 15% in some newer types. Then there is the
construction; most are R (Steel belted Radial.) But there have been bias ply
, fiberglass belted, cotton or nylon cord too. I haven't mentioned tread
style for "OEM" style, Rain Snow, ice-studs,or off-road. and sidewall
colored rubber, black, white narrow or wide, or red. And we call all the
possible combinations "Standard Sizes!" and I expect the tire manufacturers
think of these as "Standards but sell different ones to each manufacturer.
Also I didn't mention the wheel-lug "Bolt pattern " I can recall at least a
dozen incompatible versions from four to 24 studs or nuts to five to eight
lugs. And air pressure in the tubes or tubeless from 22 to 175 PSIG. We
call this plethora of tires and wheels a standard? And I have not included
mower, tractor, off-road, or trailer tires!

Let us NOT regard Federally mandated Regulations as size "Standards!"
