Wrong kind of battery. But this does not help with the argument that their are 15,000 more components in a gas power vehicle. Because they cheat about what they count as a component. If you take the number of components in that simple diagram(12) and multiply by 9000 then you get 108,000. That doe not include the main battery cases, tie bars, current and temp sensors.
Also Combustion engine manufacturing is automated as well.

Also saw a video showing that even the casting process is highly automated.
