Tesla is targeting mid-2027 for full battery cell production at Giga Berlin, which would end a transatlantic detour in which the German plant ships electrodes to Texas and receives finished cells back, TeslaNorth reported, citing plant director André Thierig at the Nov. 11 Automobilwoche Kongress, as relayed by the organizer’s report.
Thierig said Berlin already produces electrodes, TeslaNorth reported. In May, Tesla outlined a $250 million investment in Berlin battery production, with planned annual capacity of 18 GWh and more than 1,500 additional jobs, described at the time as enough for roughly 225,000 to 300,000 Model Y vehicles a year. TeslaNorth emphasized that those figures describe the planned battery operation, not an output level already achieved, and that the investment is aimed at Tesla’s 4680 programme — the cylindrical cell named for its 46-millimetre diameter and 80-millimetre height. Making cells is a separate milestone from assembling packs or building more cars, the report said.
On vehicle output, Thierig put current production at 7,500 Model Y vehicles a week, after Tesla Manufacturing’s 7,000-vehicle weekly milestone announced on Oct. 23. The plant passed 750,000 vehicles produced in May 2026, after building more than 61,000 in the first quarter, TeslaNorth reported. A second factory remains undecided, including its product; Thierig said it would not simply be another Model Y factory if built, and that Tesla plans a building application this year. An October proposal for a second hall of around 536,000 square metres, compared with roughly 219,000 for the existing hall, envisioned construction starting no earlier than 2027 as part of a longer-term expansion toward one million vehicles a year. TeslaNorth said the scale of that proposal does not mean the additional factory or a new model has been approved.
