Elon Musk has confirmed Tesla’s new structural battery design, and 4680 cells are first going to Mannequin Y, which will probably be produced at Gigafactory Berlin subsequent 12 months.
We already had a good suggestion it was taking place since Musk teased that Tesla will introduce a “core structural design change” with Mannequin Y produced in Germany, but it surely’s not confirmed.
The CEO confirmed on Twitter that the brand new structural battery pack know-how will probably be first carried out in Berlin:
Berlin will use 4680 cell with structural battery pack and entrance & rear single-piece castings. Additionally, a brand new paint system.
Tesla plans to first begin Mannequin Y manufacturing at Gigafactory Berlin in the course of the second half of 2021.
Musk added that he believes it’ll take about two years:
Lot of recent know-how will occur in Berlin, which suggests important manufacturing threat. Fremont & Shanghai will transition in ~2 years when new tech is confirmed.
The brand new know-how certainly must be confirmed. It’s fairly a radical change of how automobiles are produced.
It’s not solely about producing the rear and entrance underbody in single items of casting, but it surely’s additionally about linking these two items with the battery pack itself as a substitute of a daily chassis by which you put in the battery pack.
Musk added on Twitter at this time:
Battery pack will probably be a bonded construction with cells offering shear switch between metal higher & decrease face sheets, eliminating many of the heart physique components whereas offering higher torsional rigidity & improved polar second or inertia. This can be a main breakthrough.
After Tesla unveiled the radical new design final month, a number of individuals identified that it could possibly be a difficulty with restore in case of a crash.
The CEO briefly addressed that at this time:
The crash absorption rails may be reduce off and changed with a bolted half for collision restore.
Tesla’s new structural battery pack requires the brand new 4680 battery cells with a purpose to work.
The automaker is at the moment ramping up manufacturing of the cells at its pilot plant in Fremont and goals to achieve 10 GWh of annual manufacturing capability by the tip of subsequent 12 months.
It could be sufficient to provide over 100,000 Mannequin Y autos per 12 months.
