hi guys!! i m working on a project POWER GENERATION USING SMALL WIND TURBINE..
I have done 90% of the work.. I m using the following components

=>PERMANENT MAGNET DC MOTOR (max voltage=40V, max current=4.4A, RPM=450)
=>555 timer based Charge Controller from (mdpub.com/555Controller/)
=>PVC Blades 1meter radius
=>14 feet high assembly for elevation
=>12V 20AH lead acid dry battery

Everything is ready , charge controller is working fine except the following question which is irritating my mind.. PLZ ANYONE CAN HELP ME OUT THIS
....IS it compulsory that battery should be charged with uniform current?? because wind power is always varying that produce varying current!!! my biggest problem is to identify the component in my 555 charge controller that regulates the varying current to uniform to charge the my 12v 18AH battery...(I have made 555 timer based charge controller from mdpub.com/555Controller/... furthur more i have noticed that this charge controller is more of a switching device that switches dump load on and off when required rather than a "CHARGE CONTROLLER").... plz respond!

 

Here is the list of components of 555 based charge controller
IC1 - 7805 5 Volt positive Voltage RegulatorR3, R4, R5 - 1K Ohm 1/8 Watt 10%
IC2 - NE555 Timer ChipR6 - 330 Ohm 1/8 Watt 10%
PB1, PB2 - NO Momentary Contact Push Buttons R7 - 100 Ohm 1/8 Watt 10%
LED1 - Green LEDQ1 - 2N2222 Or Similar NPN Transistor
LED2 - Yellow LEDQ2 - IRF540 Or Similar Power MOSFET
RLY1 - 40 Amp SPDT Automotive RelayC1 - 0.33uF 35V 10%
D1 - 1N4001 or similarC2 - 0.1uF 35V 10%
R1, R2 - 10K Multi-Turn Trim-PotsR8*-R9* - Optional 330 Ohm 1/2 W Resistors
