Here are a simple electronic circuit diagram Project of Solar Cell NiCad Charger, this circuit is a very easy build.
Solar Cell NiCad Charger Circuit Diagram:
Parts List:
R1 = 820K, 1%
R2,R3 = 75K, 1%
R4 = 1M, 5%
D1,D2 = 1N5817, Schottky diode, or NTE585
L1 = 100uH, coil
U1 = MAX639, integrated circuit
C1 = 100uF/40V, Electrolytic capacitor
C2 = 47uF/40V, Electrolytic capacitor
Additional Notes:
The MAX639 has its own current limiter build in, set for 200mA. Plenty! Make sure that the charging NiCads can handle the continuous current of 200mA, for example, NiCad battery packs of 1700+ mA used for R/C (Radio Control) cars and electric aircraft.
