For Tesla's the battery pack is about 1/4 of the vehicle's weight. The battery pack weighs around 500Kg and the car is around 2,000Kg, depending on the model. The main problem as EV manufacturers look to shave weight the batteries are going to become more integrated into the car's structure, which is going to make them harder to remove and reuse the cells at the end of the car's life.
- r00fus 6y agoDo you have any examples of designs where batteries are literally integrated into vehicle structure? The iconic Tesla battery-skate design is still modular/replaceable for example (they're all 18650/2170/etc cells).
- Retric 6y agoIndividual cells might in theory be modular, but Tesla for example is gluing them to their battery packs which makes them much harder to reuse at the individual cell levels. The battery pack it’s self is becoming a structural element though it can still be removed, but unfortunately it’s proprietary. On top of this EV batteries are getting very close to lasting the normal lifetime of the vehicle. Car manufacturers are likely to tray and leverage this as a form of built in obsolescence by making replacing the battery unappealing under normal usage patterns.

In that article it specifically mentions the cells being "bound" (their words not mine) into the honeycomb pack.
