Is it likely that current cars would be compatible with batteries that are that different to not even be Lithium in 10 years? If I look at say my laptop or phone, they definitely aren't compatible with newer batteries even if it's technically feasible so why would we expect cars to be?

It’s a software update to support different chemistries. This is how Tesla supports various pack types (Li, LFP, etc) across vehicles and stationary storage products.

  To clarify: did you mean HW update? For instance, I can't imagine a software update changing my battery chemistry from Lithium Ion to Nickel Cadmium.

    I think they meant that _supporting_ this type of battery is a software update. Software can't do matter-energy conversion yet.

    Your car doesn't have to know about the "chemistry" of your battery. It just needs to know specifics about voltages and power draw and temperatures. This is what drivers do. This is like suggesting that my computer can't go from AMD to nvidia because they would need to know deep specifics about AMD's proprietary chips to support them. But that's what drivers are for!

      That’s because your video card sits on a standard well defined port. Where as charging an EV right now comes a bunch of plugs, voltages, charging times, etc. until a unified open standard is reached where you can go from super charging a Tesla to charging a sodium hyndai is reached, this whole ev dance will remain anti consumer.

    It's "just" different charge profile; wouldn't need any hardware change. Most chemistries can be charged using the same "constant current up to this voltage, constant voltage to the max voltage" method, just need to set the right values.

Yes, it is likely. As long as the form factor is well defined or standardized, new battery chemistries are self-contained. Think of, say, how rechargeable AA batteries can fit into standard alkaline AA slots. The reason it's not true for laptops is that batteries aren't standard form factor sizes in laptops.

You might notice that Li-Ion AA batteries CAN'T be charged by Ni-Cd or Ni-MH AA battery chargers. Even a smaller change like Ni-MH to Ni-Zn requires different equipment.

They were shoehorning V8's into miatas, well outside of the warranty period. Locked into obsolete engineering is a crutch/impediment, not innovation. Seeing the 4G rollout was a good economic course in environmental pollution and abandonded psuedo-innovation. All of the older surplus 2G/3G/4G hardware and abandonded software was sold to developing countries. Now every device on tcp/ip has inferior muck with an out-of-date ecosystem. Desktop computing had it right when the information superhighway still existed. Just install new hardware thats backwards compatible (the hardware was forward compatible by design). The tabloid quality fodder and disposible commerce has always been 3rd world, much in the same way that tcp/ip evolved. Anything for an inferior integer to stay relevant, huh? The environmental impact is someone elses problem :p
