What charging port is this?

[MtotheC]

My work has an "EV charging station" that uses this large metal/industrial port attached to a large power shutoff switch. It's been there for many years and no one can tell me what type it is.
There is no cord, just this female end angled towards the ground, about 4 feet off the ground.
They told me today they can't wire a 240 plug for me to use my mobile charging connector with, since they were quoted a $3000 install, so I'm trying to use what they have in place.
Any idea?
Is there an adapter to use for this to charge my car at work?
Picture attached .Thank you!

IEC pin and sleeve. Can be 480V, you’ll need to know how it’s wired. There is a corresponding male plug with 4 pins that plugs in there. Making it work will require a custom adapter cable.

But I think that I do see some 120V plugs above there. Industrial plugs are often 20A and they can provide 4 mph.

I've seen that when a mobile MR or CT semi trailer pulls up to a hospital--needs a whole lotta juice.
