Pantographs and brains

In an electric vehicle charging system, the pantograph structure lowers onto a bus roof to charge the batteries.

The charger is physically a large electrical cabinet, over 6 ft tall. An electric vehicle charger cabinet is connected to 1-4 pantographs.

A colleague said that “pantographs don’t have a brain”. So technically they don’t have their own power rating – it’s the charger that delivers power, not the pantograph itself.

Does this imply that the electric vehicle charger has a brain?
That the brain is a computer?
That a computer is a brain?

I don’t think so, but these are cool to see.
