An undated announcement, posted on the website of the district where the plant is located, revealed that the expansion plan would increase the powertrain capacity of Tesla's Shanghai Gigafactory to 1.75 million units a year from the current 1.25 million units, but did not say whether Tesla had decided to go ahead with the expansion or was simply seeking approval for potential future capacity, the report said.

In addition, the announcement said that Tesla would seek a license to produce soft-pack cells,The pilot production line has an initial annual production capacity of 20,000 amh cells, can be used by one Model Y. It is worth mentioning that Tesla has never used this kind of battery in its electric cars before. Due to the different structure, the layout of soft-pack battery can be more flexible, but compared with the current mainstream rigid battery, its safety needs to be further verified.
