Never understood this obsession with switching to 2170.
We know Tesla as a company is cell constrained (that is why no power wall) - so why would they want to switch ?
- Because they are using Fremont space that could be used for Model Y or other production.
- Supporting additional parts adds costs to production. Any cell chem updates will be unique for both batteries.
- Shipping cells from Japan adds cost.
- Panasonic lines in Japan are very old, production cost is likely much higher then GF1.
- Pack design using different cells adds to development costs.
- Model 3 pack is more advanced then SX and allows for more advanced track mode capability.
I don't have the Excel listing the input costs for GF1, Pana Japan and the opportunity cost for wasting 1/4 or more of the plant space in Fremont making 18650 packs and motors. Combining 3 & Y should save at least a billion versus building a new line in Sparks and it reduces future risk if there is a recession or other external factor reducing demand.
