EV ( extended validation ) certificate are all SSL/TLS web-based certificate that are issued by a CA that does "extended validation " of the requester.
What this means to me and you?

To acquire a EV cert take slightly more time, since the signing CA has a few additional steps, checks and requests to under take. It can take anywhere from 3-10 days to acquire these types of certificates.
If your bored, the CAforum has a EV guideline that you can search & read for the latest revisions and requirement. This breaks down the guideline that the CAs must execute and what's involved in the process.
Who uses EV certificates?
Most banks, online markets , any sites where electronic commerce & the potential for crime or fraud are higher.
