Tesla is installing 200 gigawatt-hours a year of battery cell capacity in 2022.

True: during or by the end of 2022, Tesla installed its own in-house battery cell production capacity of about 200 GWh a year, meaning equipment installed with that nameplate rate even if not yet producing at that rate. Allow about ±10% (180 GWh or more). Mostly true: installed capacity was somewhat below that but at least about 160 GWh. Mostly false: installed capacity was well short (roughly 50 to 160 GWh), or about 200 GWh was installed only after 2022. False: installed in-house cell capacity at the end of 2022 was a small fraction of 200 GWh a year (under about 50 GWh), as shown by Tesla's own reports or dated analyses.

   “Regarding batteries, production rate of 4,680 cells reached 1,000 cars a week at the end of last year. And we're increasing capacity for 4,680 cells by another 100 gigawatt hours as announced at Giga Nevada yesterday.”

   “As far as where we stand in Texas, one of four lines are in production with the remaining three in stages of commissioning and install.”

3. E3 Tesla confirms 4680 battery cell production is now enough for 1,000 cars a week Electrek · 25 December 2022

   “Tesla has confirmed that its 4680 battery cell production has now reached a level that can support the production of over 1,000 cars a week.”

The evidence gives a 4680 production rate supporting over 1,000 cars a week (E1, E3) and says one of four Texas lines was in production (E2), but no item states Tesla's installed in-house cell capacity at the end of 2022. The criteria depend on that installed figure, so the evidence cannot place the claim in a verdict band.
