How Can I Improve My Homemade Wind Turbine's Charging System?

Click For Summary
SUMMARY

The discussion centers on improving a homemade wind turbine's charging system, utilizing a treadmill motor with specifications of 95V at 5-6k RPM and 22.5 amps. The user is experiencing inadequate voltage output, ranging from 4-14V, due to a mismatch between the motor's high RPM and the circuit design. Key components mentioned include a charge controller purchased for $14 and a voltage booster from Amazon. The user is advised that the current setup is insufficient for charging six 6V batteries, as the 1A output from the voltage booster is inadequate for effective charging.

PREREQUISITES
  • Understanding of basic electronics and circuitry design
  • Familiarity with wind turbine components and their specifications
  • Knowledge of battery charging requirements, particularly for lead-acid batteries
  • Experience with voltage boosters and their limitations
NEXT STEPS
  • Research effective circuit designs for wind turbine charging systems
  • Learn about battery capacity and charging rates for lead-acid batteries
  • Explore alternative voltage boosters with higher current output
  • Investigate the use of MPPT (Maximum Power Point Tracking) charge controllers
USEFUL FOR

This discussion is beneficial for DIY enthusiasts, renewable energy hobbyists, and anyone interested in optimizing wind turbine charging systems for better efficiency and performance.

Hello! I recently built my own wind turbine. The motor is from an old treadmill, the blades are 5 pvc blades i made from scratch. So I built the whole thing, but the circuitry doesn't work so its just basically looking cool and doing nothing. My roommates are giving me crap about it, but they are dweebs. Anyways I really could use some advice/guidance on this setup I designed (I think its a design). I attached a photo of the schematic, go easy on me I am still learning about electronics.

Charge Controller: http://www.ebay.com/itm/331426976171 which i got for 14 bucks at the time... unknown why!
Voltage booster: https://www.amazon.com/gp/product/B008ATU2X8/?tag=pfamazon01-20

Motor specs: I think are 95v @ 5-6k rpm - 22.5amps


Since the rpm's on the motor were super high I was only seeing between 4-10V sometimes 14V. So i had to change the circuit up a bit... Hence the bizarre schematic HERE

Basically i was going for this http://www.hydrogenappliances.com/Parallelcharging.html

Thanks!

God, what a mishmash. You have a 22A generator feeding a 1A voltage booster feeding a 440A diverter. Then 6 X 6v batteries. Are those golf cart batteries?

1 amp is only enough to trickle charge those batteries.

You say it does nothing. What voltage and current measurements do you have?
