    Needs to be an option to put these into todays EVs. You shouldn’t have to buy a brand new car to get better battery technology.

        Uhh do what? You’re assuming the cars last less than 10 years? Who are these people throwing away cars after such a short time?

          It really depends on where you live. There are some parts of the world where environmental factors like ocean humidity or winter road salting will cause a car’s frame to rust through in a few years if you’re not careful. Look up the Rust Belt for an example.

          On the other hand, if you live somewhere warm and dry, your car’s frame and body will outlast its original mechanical components.

            “Rust Belt” isn’t literal, it refers to an area of the US where industrial manufacturing declined significant in the second half of the 20th century. It’s called that in part at least because its previous moniker was “Steel Belt”.

            No that’s just proper maintenance… allowing salt to sit on the car constantly is not keeping up with maintenance.

            Also as the other user has stated rust belt has nothing to do with cars rusting.

          I read about a survey that found Tesla batteries were still at an average 85% health after 250k miles. Not bad at at all

          I think you’re talking about batteries from nearly 15 years ago, which did degrade significantly with age and/or use. There has been a significant and noticeable improvement since then. The person you were taking to did say today’s batteries.

              When did you last lose a car to engine failure? Electronics, gears, suspension, stuff like that, but not the engine. They have to over engineer the battery because the earlier popular electric cars had bad batteries and they have to over-compensate. Hence today’s batteries.

                Engine failure doesn’t mean the car is done. You can rebuild engines for a 1/10th of the cost of another car. The engine is not the only thing that makes a car a car. Just like batteries should not be the only thing that makes an electric car a electric car.

                  Yes. The person I was replying to thought it was somehow bad for the battery to outlast the car. I was making the point that that’s fine. In response to your point about the cost of an engine, I should say that batteries are a far bigger part of the cost of an electric car - it’s really just not very complicated apart from that - very few moving parts indeed compared to a combustion engine. That’s why the car companies aren’t very keen - unless they make their own batteries, they’re not adding as much value when they manufacture them. They prefer to push the hybrids which have the complexity of both and a lot less battery capacity (but very much don’t have the advantages of both for the driver).

                    I see, batteries do seem to cost more but the way I see it, 30k car and then a 10g new battery pack and your good for another 200k miles, I just don’t see why you would go with a new car again.

        They outlast the car, but don’t have the range and take too long to charge, that’s the problem, not the longevity.
