> It's a great idea, being put in practice It's a glitzy demo which has been attempted multiple times and has failed every time (to the surprise of nobody, Tesla was one of the early demo-ers, guess where that ended up?), NIO is still losing money hand over fist and survives only thanks to the CCP keeping it afloat. > Also, not the first industry that would rely on some level of standardisation. You'd need the standardisation first. And making batteries field-replaceable with limited equipment means the battery modules need to be significantly more resilient, as well as more complex (not only do you need automatic disconnects for the electrics, but you also need to handle cooling), which translates to less capacity because you need room for all that, and it's harder to integrate structural support with the battery modules so the chassis also needs structural improvements there. The alternative is to automate the entire thing, which means even more complexity, and now the system needs to be aware of every vehicle involved. The entire thing is a staggering amount of complexity to mostly lower capabilities.
