Elon twitter: Model Y structural battery pack is next level
No, you can unbolt the battery pack. The battery pack is a very rigid body thank to to glued cells inside and the two metal clamshells to enclose them. The battery pack is multi point bolted to the chassis and so the chassis is a lot more rigid than normal EV where the battery is only a dead weight. But service can always unbolt the battery

Is cell-to-pack(C2P)/structural battery technology massively
First of all, cell-to-pack(CTP) != structural battery. CTP means it eliminates modules which saves weight and space, CTP can be structural battery but are not necessarily structural battery. I think CTP is definitely the way to go. Structural battery is a double edged sword, but EV manufactures will gradually pivot to it, because it offers a

What is Tesla''s Structural Battery Pack? Advantages, Disadvantages. Tesla first mentioned its next-gen battery design called "Structural Battery Pack" at the Battery Day event in September 2020. The structural battery pack is a kind of electric vehicle battery that is cleverly designed to efficiently fit into the car.
Tesla Model Y Structural Battery Pack Is Removable Via 143 Steps
Serviceability is my main concern around the use of structural battery packs, along with the potential safety concerns after an impact/crash. Batteries won''t last forever, and we should be designing EVs to make servicing or replacing their batteries as easy as possible so these don''t become paperweights in 30-40 years.
The integration of battery packs into the Body in White
A particular battery pack structure may be common to many models with different upper body shapes such as a sedan, hatchbacks or SUV. As the model''s number or diversity increases, combined with
Does the structural 4680 cells mean harder battery repairs?
About the only thing they can do is replace the entire pack. Just look at the Munro videos on the Model Y battery pack. That thing isn''t being repaired - it''s built to be an unrepairable solid piece. So if the structural battery pack fails, then instead of replacing the pack, they''ll probably just scrap the car and replace it completely.
Structural battery pack : r/electricvehicles
The stiffened chassis is one benefit. The biggest one is probably being able to stiffen the chassis while lower weight. To stiffen a chassis with metal structural members (while the battery cells are still ''along for the ride'') is a much heavier way than lessening the amount of metal and using the cells (that again, would be there anyway) to help carry the load.

Musk Says Model Y''s Structural Battery Pack "Far From
The good news is Tesla CEO Elon Musk is aware of this and says there''s plenty of room for improvement with the structural battery pack. In a reply on Twitter to a post that referenced Munro & Associates'' recent removal of the 4680 structural pack as part of a Model Y teardown series of videos, Elon Musk admitted that the structural pack
4680 structural pack still scores in the "GOOD" range in small overlap and side impact 2.0, so it''s a safe car, but technical measurements wise, the "traditional" structure of the LONG RANGE model with the standard 2170 batteries (non-structural pack) posts SUPERIOR crush measurements on small overlap and side impact 2.0 intrusions.
How Repairable Will Structural Battery Be? | Tesla Motors Club
This new structural battery pack with structural adhesives being stressed as a structural load bearing member with electrical components will need quite a bit of lifecycle and impact testing IMO. The adhesive selection alone will almost certainly be iterated over the years once real world testing results are in. I''m not saying not to do it, I''m

When Musk says the battery cells would be a structural component, he''s referring to the battery box itself. The box has 5 beams running length wise along the pack, and two beams running width wise at the front and back of the pack. I imagine these are steel. The 3 interior beams are removed. The exterior beams are hard to say.
