Re: Gas or Hybrid conversion?
Heres another one.... a PTO driven, 15000 watt version!
Probably overkill but maybe in something more powerfull than a golf cart motor? |

Re: Gas or Hybrid conversion?
Find some way to convert it from AC to DC and that gen head would work I suppose. Power it with a 23hp V-twin.

Re: Gas or Hybrid conversion?
This is interesting....
48V 3000 Watt Generator: http://www.alpha.com/Products/Alphas...aGen-DCX-3000/ Could be used to charge the batteries. |

Re: Gas or Hybrid conversion?
I looked around for some generators with DC output. Not much out there. So you'd have to convert the AC output from the generator to DC. Or find yourself a EE who can build it.
So can you charge a cart's batteries while you are using them to drive around? I was actually thinking about modifying an electric cart, maybe some kind of pulley off the rear diff that drives the generator, which is charging the batteries. I'm pretty sure you'd use the power faster than the generator would charge the batteries, but I figured you could possibly double or triple the distance you can go on a charge. |

Re: Gas or Hybrid conversion?
The link above is a 3000 watts 48V DC generator. It's more power output than the Delta Charger which is about 1000 watts.
The question is how many watts does it take to run the motor at full speed? |

Re: Gas or Hybrid conversion?
Forget the idea of using a generator powered by the cart to recharge the batteries while driving. If that would work, you would have a perpetual motion machine! All generators and motors have losses, in other words, you get less power out than you put into them. The generator takes power to operate. That power adds to the load on the motor, more so than the generator produces. Bottom line is this is a bad idea and wont work.
These carts do have regenerative braking, which DOES convert braking energy into charging the batteries. This works because when you are stopping, the motor is not providing propulsion, but is used as a generator during deceleration. This slows you down without use of brakes. You could extend your range by running a gas powered generator to charge the batteries. |

Re: Gas or Hybrid conversion?
If you were to run a gas powered generator would you be able to charge the batteries while the golf car is in operation?
