If the government regulates them*

Last nearly forever? That needs to be broken down into details. Aren't batteries for EV limited to about 10 years of use? And they're a costly replacement?

A good solution would be to make EV batteries easily swappable instead of "charge stations"...

Electric motors can last a really long time, assuming no defects, they should outlast the battery by a Longshot.

That leaves the battery, and an LFP battery should also last a hell of a long time, probably a decent way into a million km before you have degraded to about 80%.

If you got those key items lasting, then it just depends on how well the rest of the car holds up, but replacing small parts while the motors and battery works is probably always going to be more cost effective.

The problem is the battery is a wildcard still.

We know how long those LFP batteries should last in a car, but they're also pretty are in cars and we don't have that real world data yet.

I also fear that OEMs will still gouge us on replacement batteries 15 - 20 years from now when costs are even lower and replacing the battery shouldn't be so expensive.

There's an old expression: Any idiot can build a bridge that stands, but it takes an engineer to build a bridge that barely stands.

If a car has a warranty of 10 years, it will last 11 years.

I had already read of the first teslas model S getting to 1M km with ordinary maintenance alone, so it should be pretty easy to achieve. Of course it won't be done as it wouldn't be profitable.

My family bought an electric forklift for their factory in the early 90s. I think it is a Yale.

My sister has since taken over the forklift for her company and she has only replaced the batteries and the controller once.

These things are cheap to replace and not as much of a mystery as ICE engines.

I am seeing people replace old Prius hybrid batteries themselves with basic tools now.

I think the only thing I would be concern about is the crash safety for cars. Newer cars are safer. I think that would be the only draw to buy a newer vehicle.

I mean most things can, it just isn't profitable...

Planned Obsolescence, baby!

That said, we might be able to make industrial scale recycling an economically efficient activity if we build more durable goods with a longer lifecycle and limit the availability of new territory to strip mine and abandon.

So much of our "cheap" access to minerals and fossil fuels boils down to valuing unimproved real estate as at zero dollars and ignoring the enormous waste produced during the extraction process. Properly accounting for the destruction of undeveloped real estate and the emissions/waste created during industrial processing could dramatically improve how much waste we produce and - consequently - how long our durable goods last.

Its really worth reading the whole Article. Im looking forward to long lasting EVs, but I really fear that, what the author also described in his article, may come true. I think we will see that car manufacturers will start to act like hardware company's and start to force you to regularly buy a new car by making your car incompatible to new features or by designing it to fail after a few years.

They started to do this decades ago. Generally any given part in a car might be left unchanged for 5 or 6 model years before it gets changed, often for completely arbitrary reasons. For many cars, if it's over ten years old your only hope for a replacement part is the junkyard.

Or your local friendly 3D Printer mad scientist. Provided they have a metal and a plastic printer.

Yeah, options open up for some massively popular models or otherwise very well loved models. I got replacement gears for headlight motors for a 90s car with pop-up headlights, because people got tired of the OEM design wearing out so easily. I suspect someone trying to keep a Pontiac Aztek going might have a harder time finding enthusiasts keeping things alive.

Or, God forbid, a Chrysler PT Cruiser. I liked the look, shame their drivetrain is universally shit.

After ~20-30 years, rubber gaskets and seals and cable insulation start failing. Plastic becomes brittle, especially if exposed to the sun. How do they solve this problem?

[–] [email protected] 1 points 7 months ago (2 children)

My guess is the thermodynamics of a hot engine makes the rubber and plastic parts fail more quickly than they would otherwise.

Modularity of construction, so that rubber components can be replaced without scrapping the whole vehicle. Reducing reliance on plastic parts, or improving the ease and quality of plastic recycling, so that we can fix the exterior components without sacrificing the chassis and core parts.

Especially if it's made by Delco. Ask me how I know.
