Do electric cars need wind generators to keep the batteries charged?

An all electric vehicle.

Answer
No, there are a number of ways to charge the batteries. Battery electric cars primarily charge the batteries from a wall outlet.

Solar, fuel cell, and series hybrids can charge batteries using the supplemental power source.

Vehicles that have power transmitted to them can charge batteries in addition to using the transmitted electricity to run the vehicle: http://electric-vehicles-cars-bikes.blogspot.com/2010/10/haloipt-launches-first-wireless.html

There are also a number of ways to capture the power of inertia to charge the batteries these include:
-- Regenerative Braking (usually it is a drive motor that is turned into a generator for regenerative braking but in some cases a separate generator may be used. It is also possible for this to be attached to a fan but this also will have some effect at braking the vehicle.
-- Regenerative suspension (shock absorbers that produce electricity)

It might be possible to park your vehicle at the top of a mountain each night. As you drive down the mountain the regenerative braking could charge the vehicle. However you would have to top off the charge before you climb the mountain again. As they say there is no free lunch.

--A stationary Wind Generator is just one method to produce electricity that can then be used to power the electric grid or an electric car directly.

will I be able to use a plugin electric vehicle in an apartment?

Assuming I have a plugin port in my parking area but the parking is NOT secured parking, meaning anyone can walk up to the car, how will I be able to use plugin vehicles? What stops someone from walking up and A) unplugging the car B) stealing the plug C) cutting the cord? Do I need a secure parking lot and/or a garage?

Answer
You might ask the same thing about a motorcycle parked in the same lot. Easily someone with a front end loader or a crane could take the bike. The same is true for someone smashing your vehicle windows or taking it with a tow truck. You may not consider these likely events in your neighborhood, or you may... Your sense of security is based upon how likely you foresee the unfortunate concern. Much of this is an assessment of neighborhood rather than the potential with the vehicle.

The same is true for an electric vehicle. Is it possible? Yes. And of 365 days in a year how many times might this happen? Probably less than you might imagine.

I would be more concerned with the possibility of someone accidentally cutting or tripping over the cord. There are several possible ways to work around this:

1. The cord could be armored just as there is armored but somewhat flexible electrical cable called "bx" which is used for electrical wiring.

2. The lid of the charging port could be configured to close and lock over the plug or some aftermarket device could be applied to lock in the cord.

3. The charging circuit could be alarmed with either a silent (app?) or audible alarm to warn when an incomplete charge has been interrupted or cord disturbed. Some cars have perimeter alarms on them.

4. The system for charging could be switched to a wireless charger. This is essentially a pad you could drive over that would then charge your vehicle wirelessly. Eventually, I think all public chargers will be wireless. http://electric-vehicles-cars-bikes.blogspot.com/2010/09/delphi-working-with-witricity-on.html

5. Or your could have an enclosed or secure parking lot with a guard to reduce but not eliminate the risk.
