That is likely to Cause Fires like EV Semi conversion w/ swap-able batteries did last week...
Massive EV truck fire on freeway puts thousands at risk https://www.youtube.com/watch?v=GGQXYL_eHHs
Massive EV truck blaze was taxpayer-funded. https://www.youtube.com/watch?v=wLn_H-Ltkd0 update info to first one
both YT @AutoExpertJC that likes EV for what Niches work for.
@ lest that didn't burn in a tunnel likely Killing other people.

Ever since the Biden EV craze came about, I've wondered about this or something similar.
Instead of having charging stations, why can't the Feds dictate to the EV manufacturers a mandate that all EV vehicles must have a same shape and system to allow battery swaps at swapping stations. I do realize that the EV concept is still young and in development but, I distinctly remember having a small fleet of electric/battery powered forklifts. When the forklift ran low on power, it was designed for the operator to swap out battery (power sources) in about 5 to 10 minutes. There would obviously be different batteries for semitrucks versus pickups and cars but, a standardized type battery that could be swapped out seems to make sense to me.
Yeah, it would be more expensive but, the biggest reason my wife won't consider an EV is the short distance it can be driven before it must be recharged which currently takes quite a while to do. Just a thought.------------------

Forklift & some others have use Gell then AGM Lead batteries for Decades.
1. They don't need Cooling to Charge or Discharge like EV do. They do get warm but case dump the heat most times...
2. Their batteries often do not last long because most try to drain to the bottom even after meter say "Empty."
3. If they run the units @ max speed, load, or both, the batteries may get too hot etc.
all causing short charge cycle & short lifetime overall.
When Possible... is why Propane power forklifts often work better.
Early Leaf had Air Cooled Batteries that while didn't cause fires, causes:
Battery too hot/cold from weather that day.
Battery overheating during Running.
Result: Rage Dropped a lot & shorten Battery Life in the long run.
But many Swapping scheme will use air cooling anyway because need to have easiest "plumbing" & electrical connections.
In the case of the EV semi above to save Weight because Weight of Wet Coolant + the "tank" to carry it in the batteries.
Many to Most Current EV the battery Case is Structural to the vehicle & if switch to swap-able many vehicle will require major mod's to them not just parts added to take removable batteries.
Similar problems w/ current Phones w/ builtin batteries or replaceable ones. My Moto G Power is sealed so drop in water don't care & much easier because can't replace the battery. I have other phone say seal ageist dust water but battery door is very hard to install & make sure is 100% right or have problems soon.

There is no need to battery swap. Charging an EV really doesn't take that long. [This message has been edited by Wichita (edited 12-06-2023).]

I agree. Swapping stations will become obsolete very fast as safe, fast charging batteries (as in seconds to minutes) are just around the corner.

Hot swap only makes sense in a very small situation. We have 7000+ robots carrying all day and in that same building only 7 that we manually change the batteries. They are super freaking heavy and require a dual bay sled to transfer.
We are just now getting 1 charger across cell phones. I don't see this as viable across fleet vehicles. In Oklahoma our UPS trucks run on CNG (MANY) they run all day. It isn't all rural, but driving back to UPS site 2-3 times a day to swap batteries isn't feasible. Even worse for Amazon trucks as they are DSP and not owned by Amazon. IE each DSP can use whatever trucks they want to run. I know America isn't the only country, but it is the largest landmass and economy mixture. If it doesn't work here, it isn't likely to be the end all be all. Paces like Montana wouldn't even be an option. I am not anti-EV, but I doubt it is even close to its' final form. We need a huge battery jump. I know GaN (gallium nitride) is making strides in heat and charging speeds this hopefully helps. My thoughts are the depletion of lithium stores and their disposal. It seems to take a great amount.
I want to say I have seen hydrogen fork trucks becoming the new norm. Isn't that what car guys have been saying was viable and killed by GM etal for years? I think I heard Elon talking about it recently too, not that he is any kind of engineering mastermind.

That's news to me, but okay.
I don't own an EV, but the last I heard was 15 minutes for a "top off", or several hours, minimum, for a full charge. That might work for commuters, but not for anyone who has to cover a lot of miles, for a living.
It'll be interesting to see what happens with batteries, in the coming months or years. I'm not really against EVs, but I don't think we're ready, from an infrastructure standpoint.[This message has been edited by Raydar (edited 12-07-2023).]

Well, my suggestion was not to utilize the same batteries that fork trucks use. While admittedly, I didn't say what kind of battery, my intent was to suggest the same type of batteries currently used in EVs. Realizing that requiring all EVs (similar type EVs) would mean that the vehicles would require structural changes to make this possible. Regardless, it was just an idea and as I see it, the American public (as a whole) do not want EVs, a national recharging system still doesn't exist and EVs are more expensive to repair when that becomes necessary.
Will we eventually end up with most of us driving EVs, probably but, I don't believe our President can force it nor will he see it in his lifetime.
