It's a bit more nuanced than that. The key is energy density relative to battery mass. You can have two batteries both weighing the same, but if one delivers higher watt hour per kilo it will inevitably deliver more range, all else being equal. You will increase range if you use more efficient powertrain components or reduce mass elsewhere with no changes to the battery.

This was why Jill's original statement was incorrect (bolding mine).

But so were the attempts to clarify, bolding mine:

 

So do they have test logs? I'm curious about this since if EVs can get into the 1000 mile range then a 5 min charge would give good range finally.

 

Perhaps I wasn't clear, but my point was that interpreting his statement to mean that Toyota thinks the only way to add range is to add batteries is not correct. The statement does not say that's the only way.

 

maybe these?



i didn't (and don't believe ever) say 'never'. you may have seen me state that 'never' and 'aways' are overused.

it would not be a stretch to say elon musk frequently (not always) makes wildly exaggerated statements about availability, especially when it comes to things like cybertruck. yes his finance and legal team add all the disclaimers and footnotes in formal disclosures to keep him out of hot water.

interesting. i guess yes, if this startup's individual batteries were the same form factor as existing tesla's then they could be swapped out, but i suspect a major breakthrough at some point will change the setup entirely.

 

If we increase a battery electrics efficiency...we thus increase the range? how would we do that?

 

Cell internal resistance is the main one.

 

 

Lets not confuse range with energy density. There are many methods of increasing a vehicles range, and most of them involve some kind of compromises. Battery energy density is completely different, and with current tech it is pretty much maxed out.



Toyota has been quietly working on solid state batteries, and if anything, I have far more faith in Toyota than some start up chop shop with every red flag in the play book. Toyota, and Japanese culture in general, is very humble - they do not buy into all the hype, sensationalism and hypocrisy, they take a conservative, safe and realistic approach. They won't do anything reckless like Elon Musk, who has been warned by CEO of Panasonic (leader and one of the inventors of Lithium battery tech) about fire risks with 4680 batteries. They don't get caught in the biggest emission scandal in history like VW, and then pretend to care so much about the environment that they almost renamed themselves into Voltswagen. And they don't make ridiculous claims like Elon or this new "start up" with nothing to back it up.




I don't normally read or respond to your deranged posts, but this time I will because you are spreading straight up misinformation. The Panasonic 18650s that Tesla were using until recent have existed since before 2010, their energy density has improved by maybe 10% since then. I believe right now they are using 21700, and their increase in energy density vs 18650 is proportional to the increase in volume.

Tesla 4680 battery, if it ever happens, promises 16% energy density increase by volume.

 

If it's not a solid state battery then it's DOA.

 

Maybe I missed it, but how much $$$?

 

what do you base this on? i want Mr Fusion.

 

i was just going to mention solid state, but i'm still learning about these fangled things called batteraziz!

 

Hahaha great movie!
