wind charge 36V golf cart

I am trying to do a 48 volt EV conversion.  I am thinking a charge controller ....  ??

Michael, I would recommend that you consider using a 32 volt wind machine like a pre REA Wincharger, Winpower, Parris Dunn or Wind King to name a few. The 32 volt generators will easily produce better than 40 volts. These machines are still available out there, and are built to last a lifetime. They will do a beautiful job of charging a 36 volt battery. In addition, if you want to do more than charge a battery, there are all kinds of 32 and 36 volt lights, fans, and motors available, and you can still buy inverters for use at these voltages. Also consider that the marine industry still uses 32 volts on ships so there are all kinds of accessories out there for use at your voltage. Lastly, from a transmission standpoint, 36 volts does not suffer anywhere near the volt drop problems associated with 12 volt systems, so it allows for the use of smaller wire sizes for comparable loads. We power our house and farm using two 32 volt Winchargers, and AC power is provided by a Xantrex inverter powered by our batteries. We couldn't be happier with our system. You can check out other people using 32 volt machines at www.wincharger.com  Good luck
