It seems to my that pot equity and EV is just the same. Pokertips.org has this to say about EV:

and on pot equity it says:
It's the same mathematics. But what's the difference between EV and pot equity?

EV = Pot equity + fold equity

edit: meh, this may be too simplistic, but in your post they ignore the equity gained when you bet and they fold.

Pot equity deals with the immediate. At any given time, you have some pot equity unless you are drawing dead.

EV takes into account the future. It can use implied odds or how well you play postflop. For example, pf you have 55. In a 5 way hand, your pot equity might be 17% pf. If you contributed 20% of the pot, your EV is negative. However, the potential to make a set, and win a big pot, would make this situation +EV, as long as you know how to play postflop and don't lose money when you miss your set. And you also need to know how to play and extact the maximum value when you make a big hand.

In other words, if you take the same situation, a good player and bad player will have the same pot equity but the good player will have a higher EV.

And as the previous poster mentioned, fold equity is also part of EV. Fold equity accounts for the percentage of the time you can make your opponent fold which is added to your pot equity.

EV = pot equity + fold equity + implied odds - your future bets

They basically gave the most simplistic example of EV possible. Even losing a pot can be +EV against regulars because of metagame and future hands, etc. Pot equity refers to only your share of what is in one pot.

future bets as in future bets in that hand only?
or future bets the rest of that game

Hi, just saw this post.

To POPOV, I believe future bets means bets in that street (I think you mean street? like flop, turn, river), and the rest of the hand.

I've a question to the rest of the community, how do you use pot equity to determine if you should raise or call? It seems to me that if you have a strong draw, you should raise on flop to get more bets in. How does this translate to +ve EV in the long run? And how does pot odds have in relation to pot equity?
