EV battery swapping

You buy brand new EV with best possible batteries. You go for fill up. You get old Mexican knockoff battery installed dies out 200mi in the desert with 4 kids in the car not making it to the next station? Are you angry much?

You buy a brand new gas car with a great engine and drive train. You pull into a gas station and fill up, 200 miles down the road your car quites because of poor gas (maybe sediment or water).

Are you angry much?

How often does that happen today?

Yes it's possible.

It's being done now.

Just not here... yet.

The video below is a San Francisco company working with Stellantis (Jeep, Ram, Dodge, Chrysler, Fiat, Peugeot, Citroën, Alfa Romeo, Opel, and Maserati).

That one minute commercial shows us nothing. It does not address any issues at all.
 
Why does EV car weigh twice as much as regular car and eat up tires? If you remove engine, transmission? Shouldn't it be a wash?

You'd think.

But I'm not an automotive engineer. Remember it's not only the battery. There are still electric motors, conversion units to take the battery power, etc.

Battery technology has been advancing with current batteries being lighter then old lead/acid batteries and newer solid state batteries promising even futher weight reduction.

It will take time.

Actually my wife and I bought two new vehicles in the last couple of years. Both are ICE engines, even though we are a demographic well suited to owning one EV. One car for long trips and an EV for around town. But EV's are not yet at the point where we are comfortable with them.

Never? I had a problem in the 90s with a city gas station going out of business, down to last gas? Bad gas? at bottom of supply??? In-line fuel filters filled with rust every few 100 miles. I could see it in a Volkswagen van. I kept changing it. Pain in butt. No where to complain. Station gone. New gas did not help. Took a long time.

No I am not. This is about why this idea is impossible. Your example is the customer pays for multiple batteries upfront and swaps them in forklifts. That is not the same as a customer buying one battery (included with the EV) and swapping with a battery someone else paid for upfront. The inventory cost for the EV batteries are far too prohibitive for it to work, not to mention additional service costs as this is an offsite operation. You simply cannot make a battery swap affordable with such wildly expensive batteries.
In addition to the fact that I'm not going to be happy swapping my brand new car's battery for a replacement that is 9 years old and almost at the end of its life.
 
There is no standardization on EV battery design they are VERY customized and extremely complex.
Thats because they arent restricted by a US regulation that requires it. Once infrastructure is put in place, those regulations will go into effect.

Designing for interchangeability in anything is very expensive. And the common batteries would potentially force redesigns into the vehicles themselves. It's a way bigger deal than a simple two terminal 12 Volt Battery.
 

you are the one equating swapping a car battery pack like it's a power tool

they are not ******* plug and play...... :banghead:

they are nowhere close to the same so who's the not bright one here....

A Tesla battery pack typically weighs between 1,000 and 1,800 pounds depending on the specific model and its range.

this is NOT a car battery pack.....

More context:

The Realistic Timeline (3–13 Hours)​

Even though the physical unbolting might go fast, Tesla Service Centers and specialists generally quote 3 to 13 hours of labor for a full replacement. Here is what eats up that time:

  • Coolant Management: The battery is connected to a complex liquid cooling system. You have to drain the glycol-based coolant before removal and, more importantly, vacuum-fill and bleed the air out of the new pack after installation. If air bubbles remain, the battery can overheat.
  • High-Voltage Safety: Technicians must follow a strict "Lockout-Tagout" procedure, removing the First Responder Loop and verifying the system is de-energized before touching the main connectors.
  • Software Pairing & Calibration: The car won't just "recognize" a new pack immediately. It requires a computer (Tesla's "Toolbox" software) to pair the new Battery Management System (BMS) with the car's drive unit and run a series of thermal and electrical self-tests.
  • Interior Disassembly (Model Y/Cybertruck): In newer structural packs, the seats and carpet are actually bolted directly to the top of the battery. You have to gut a large portion of the interior just to reach the mounting points.
Any EV uses coolant around the battery for your heat source

swapping a battery pack is equal to replacing and ICE motor, it's not a minute...it's many hours

.....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......
Seems to work for them "Surrons" and all the knockoff ones too.
The battery is not small, though. :oops:
It's huge. Idk what voltage, but they are 50Ah.
I encountered a kid that had one and we got to talking. I know my shit.
I don't even want a bike that weighs as much as that battery. Taleria or something like that?
And then there's the frame and wheels and everything on top of all all that.
That's the uhh..maximum efficiency of human propulsion by electric there is, IMO.
Up to a small/medium sized light personal vehicle.
I'll pull a number out my ass and say up to about 550 lbs. Plus rider.
You could probably E-do like up to a GPZ 950. But it won't get 50 mpg.
Not sure what the range will be. Not as far as a gas-powered inline 4 cylinder engine.

LOL, maybe caveman has a point--even if extreme. Can you imagine cars with batteries like power tools. Sure, just plug a Bosch battery into a DeWalt or Miluakee or Ryobi.

It would be nice if they were universal and not a pipedream.
Actually batteries like that have been used.
The problem is the proprietaryness.

boils down to that, too many unique configurations, nobody is going to sit down from the big auto makers and agree
on one size fits all, they can't

car and SUV, size, range, power and weight

The idea you could pull the battery out and charge it like your drill......LOL

better have a good engine picker, EE degree, discharge......or you will toast yourself
of fry the drive train

tried to explain this to somebody here, they were just not really understanding the complexity of it all

it's simply not plug and play, likely will never

It could be. Unlikely to happen, though.
All these different companies want you to buy their stuff, and their stuff only.
It's exactly like the problem with buying cheap China E-bikes.
Oh! The battery fits just in that spot and has to be shaped a certain way.

You and some others have lost the point of the thread.

not really, trying to say you can just swap a battery in and out quickly like a cordless drill is the whole point

can it be done.......likely, can it be done in less than 3-6 hours? unlikely

It could be able to be done in about a minute.
All it would take is a box-type plug in thing and standardized batteries.
Direct drive works. Switch a depleted battery out for a fully charged one and pay whatever. :dunno:
The company charges up your depleted battery and bills the next guy for your charged battery.
It could work. :dunno:
