What is EV
You can find here...
AKA exposure compensation, you use a Nikon D3400, it's controlled by the little +/- button next to the shutter release.

Technically no, EV is Exposure Value and is used as a method of expressing the amount of exposure Compensation . EV is explained nicely in the link above by clicknimage.
Ev shown on Weston exposure meter. It was sometimes shown on manual film cameras next to the shutter speed and aperture dials.

Indeed, Hasselblad lenses would lock to a certain value so that you could quickly choose any of the shutter speed/aperture values associated with that particular EV.

I was referring to the way the term is used in the site's Exif column, which is what I understood the OP to be asking about.
I'll often shoot -1/3 or -2/3 EV on Aperture Priority or Shutter Priority . It means that the whole image will be darker than the camera would automatically shoot it. The reason i dial EV down is so that i don't lose highlight detail in areas of the image that are very bright. I can then adjust the image back in Lightroom.
IF you shoot fully manual then EV does not do anything.

Strictly speaking "EV" does indeed stand for Exposure Value. There's a clue in the name.
Unfortunately, it's another of those terms that's rather lost its way.
Think along the lines of "Shutter speed" which has nothing whatsoever to do with the speed at which the shutter travels.
Or, how many people can't tell the difference between "dpi" and "ppi"?
We'll never change the way in which these terms are (mis)used but it's not a bad idea to understand their real meanings.

Took me a couple of seconds to catch on to the meaning of what you wrote !
Hahaha! Nice one. I saw an advert of a shutters store saying "styles that fit all budgets".
EV stands for Exposure Value not for Exporting Video.
Exposure Value is simply a figure that represents a combination of a shutter speed and aperture; 1/30 @ f/8 would have exactly the same EV as I/60 @ f/5.6 and again exactly the same value as 1/125 @ f4; all three combinations give exactly the same exposure value; I don't know anybody who uses the concept of EV; I have been into photography for more years than I care to admit and have never consciously given EV a thought.
if you really must you can demonstrate the concept yourself if your camera has Program mode; if set to P you can adjust the aperture and the shutter speed will change to compensate thus keeping the same EV at all combinations.
As "Philh04" said you could do the same with old Hasseblad lenses; the link by "clicknimage" offers a good explanation.
Not to be confused with exposure compensation when you tell the camera it is a liar and a fibber and override the camera's exposure settings with the +/- setting.
KISS .......
