What is the purpose of EV?
What is the right EV setting in a camera? My camera has the following EV settings:
+2.0EV
+1.7EV
+1.3EV
+1.0EV
+0.7EV
+0.3EV
0EV
-0.3EV
-0.7EV
-1.0EV
-1.3EV
-1.7EV
-2.0EV
When to use what?

EV is a way to correct the exposure of your photo. Generally, based on your camera's metering system, it comes up with an ideal speed at which to take the photo. This is fine when a photo displays midtones (as most photos do) and there whould be no need to adjust "compensation" or EV. So keep the EV setting at 0EV, which means you will allow the camera to take photo based on its installed metering system.
The problem with the metering system is that it can be tricked by subjects predominantly light in color (such as snow) or predominantly dark in tone (as in a close-up shot of an African-Amercian). Since the metering system will expose the camera based on the "average" tone, there are times when picture of white snow is rendered light grey by the camera. Or the dark skin of an African-American is rendered lighter. In these circumstances, you need to adjust the EV to compensate for the camera's mistake.
For instance, take a picture of a white wall and check if your cameral shows this as light grey. If it does, then you need to adjust the EV higher. So if you are at 0EV, take fotos with a +0.3, +0.7 etc. until you are happy with the photo (white comes out white).
Corolarilly, if a predominantly dark subject looks lighter (colors are not as deep), you can compensate by lowering the compensation to -0.3, -0.7, etc. until you get the colors that you like.
What it does essentially is adjust the speed of the foto. A positive adjustment slows down shutter speed to allow more light. A negative value increases shutter speed to reduce light (ergo, a darker photo).
Experiment and enjoy!

Camera Ev Setting

Your camera is programmed to try to achieve an exposure level selected by the maunfacturer's engineers.
The EV setting gives you the ability to adjust the target exposure either brighter (+ settings) or darker (- settings), according to your preference.
You will have to experiment a little to see which setting you like better. Most of the time, you set it to your preference and leave it.
Sometimes you might adjust it more in a special circumstance. If your camera has live histogram, you can see the impact of EV adjustments before taking the shot.
Good Luck

+ makes the picture brighter.
- makes the picture darker.
Cameras try to make the average brightness for a photo equal to light gray.
If your subject is really white (like snow), the camera will try to make it look gray, thus underexposing the image. You would use the + setting to compensate (probably +1.3 for snow).
If you're taking a picture at dusk, the camera wants to brighten the picture which makes it look like mid-day instead of dusk. You would use the - setting to compensate (probably -0.7 for dusk).
