If I understand the new Tesla structural battery pack thing right, it seems the direction for EVs will inevitably be to build batteries in the chassis of the car for lower weight and higher capacity and thus range. If this technique delivers on its promises, there will be no convincing automakers _or_ consumers to prefer swappable batteries, because those will not be able to compete with the specs of the structural battery. And I think to replace that one, you'll have to basically take the whole car apart. I'm interested to see how this is going to develop. I don't know if the EU law referenced in the forum thread is supposed to apply to mobile phones (are mobile phones household items?), but we can see this already happening there - in order for phones to be thin and slick, they no longer have user-swappable batteries, unless that user happens to be handy with a screw driver and owns the special bits you need to get into the phone. If a ban on hot-gluing batteries is going to be a thing, great, I think adding pull tabs doesn't increase the thickness or the weight of the phone significantly, so that makes sense. But how is this going to work out with cars with batteries built into their chassis?
