EV battery swapping

[egp320i]

Probably has more to do with corporate monopolization.
All of them want to have thier own proprietary thing which is dominant.

The car industry is not keen on sharing very well, they are a business

I just can't see them all agreeing to a universal plug and play quick swap battery anytime soon

That is what I am trying to say

different sizes, range, configure specs, etc

We are not talking about AA or C batteries here

totally different mindset

But there should be some.
Actually they're not that much different, brah. Here, lemme link you to the type of battery that is used:

GENUINE TESLA 21700 Model 3 Cells 3.7V 4800mAh | eBay

The product is a genuine Tesla 21700 Model 3 lithium-ion battery with a capacity of more than 500 Ah and a nominal voltage of 3.7V. It features a modular and stand-alone mounting style, making it suitable for various applications. This high-quality battery is designed for low self-discharge and...

Long link. Each cell is another moving part, and moving parts break down.
EV batteries are just a bunch of somewhere in between C and AA batteries welded together in series and parallel to achieve the desired output and range. With nickel strips. In a car? Thousand or more cells, easy. 1 goes out? It can throw the whole thing off. That's reality.
I say the cells need to be bigger and made more heavy duty.

not sure you are just going to swap that out due to some dead cells you can buy on ebay??

first the removal and then finding the dead cells to swap, this is not something you do in your garage
on saturday

they should be made out of polymer like your cell phone battery, just 80x larger
cut weight, safer

Do you not see how many freaking separate batteries are in that thing?
Thousands, and if any of them go bad, the performance suffers.
Each one of them little holes is a between C-and-AA size battery. Too many moving parts, IMO.
It's like 36 or more eBike batteries combined.
If one pack in the series suffers? The whole thing suffers.

right and that is why this tech is not really mature yet and it's certainly not ready for any plug and play

No, it's not.
We need big whoompa-doompa battery cells.
Less granularization and moving parts.

solid state graphine, toyota and honda are working on them

Pardon me while I don't buy in on the graphene until I see something happen.
Lithium-Ion batteries are good.
I have one with 21700 cells right now.
I had 2 more, but damaged the cells mechanically, and the packs are done.
Unless I take apart 2 packs and remove the bad and make it work.
Unlikely.
Unlikely for me to be able to do that. Oh, it was nice when they were working.
A dented cell? Done.
1 messed up cell can become the whole battery pack being messed up. Right now.
times 36X chances with a Tesla battery. Yeah, there's odds on things.

You have and EV and you damaged a cell mechanically?

this is not a novice type job, you really need to know what you are doing

I don't know how to replace a bad cell in any EV pack, never learned
not my field

Yeah, I ripped along on an eBike and the battery pack met part of the frame when ..
Ok so I jumped the thing and the battery clacked against the frame and it arced even.
I did like a rather high bunny hop on that one, just cuz I could. But when I landed the battery got dented by the frame tube.
1 cell dented and now, it's FUBAR.

Hey, hey you guys, dial it down a notch.
What is wrong with each others' theory that y'all see?
Let's segue to that, ok?
Just the facts. Go at each other with the best presented ideas.

he doesnt have a theory or an idea,, he just gave up without trying,,

I gave detailed ways to achieve the goal and hes talking about ICE powered european cars like theres some kind of connection,, and then insulted me while ignoring what I said,,

Can we reach some kind of common ground here?

 

[progressive hunter]

no personal attack, you act like you are and EE and likely you are not unless you can prove it

if it was so simply why has nobody from toyota or honda done it YET? because there are no
universal size, they are custom made for certain vehicle

you think elon is going to share tesla tech with BMW? you are dreaming

again why dont you respond directly to me so I know you ranted again,,

it hasnt happened yet because we are in the early stages of EV cars,,

as I said once there is an industry standard things will move in that direction,,

as for the tech to achieve such a thing,, we already have it,, just takes time for things to evolve,,

It's yours? Your posting manner seems to have changed. Drastically.
I may have been gone, but I remember everything since I was 2.
Hopefully that doesn't change.

well he says it can never be done and I gave him detailed reasons it can be done,,

its already being done in some aspect with heavy equipment where they use replaceble batteries meant to be changed in the field

It's yours? Your posting manner seems to have changed. Drastically.
I may have been gone, but I remember everything since I was 2.
Hopefully that doesn't change.

since we are talking about basic mechanics yes its been my field in one way or another for 45 yrs,,

You don't need to be top in your field to comment with logic

still not sure why your panties are in a wad over this

this seems like some personal involvement for you, do you love EV's that much?

battery expert for 45 years, why don't you work for tesla?

You should be retired by now, you have no more input for the industry, do you?

elon is waiting for your phone call

should also be at the age of not name calling either because you get flustered

you said its not your field not that you werent at the top of it,,

its your panties that are in a wad not mine,,

you saying something cant be done when its already being done at a smaller scale,,

and as I said all it needs from here is an industry standard to make it doable across the board,,

.....and you are dreaming if they are all going to get together in a room to make an industry standard for EV battery pack
like C and D batteries

each vehicle big or small needs it's own requirement for range, a one size fits all just does not cut it and likely never will

these companies compete against each other, they don't share their tech, they are not buddies at a party

they will never get on the same page for this to happen

not that it can't be done but that it won't be done for various factors

maybe there is a joke in there, an american, japanese, korean and german walk into a engineering board room......

companies dont make them,,

you are saying something cant be done thats literally already being done at individual companies,,
