Circuit Diagram Of Portable Solar Charger

Articol publicat in: Tehnologie

Here we see the top panel of the portable solar charger. The left meter reads the battery voltage, as properly as the correct reads charging current. The middle change selects which on the batteries is at present in your circuit. on this case, we see the fact that NiCad D-cells are in your circuit, the fact that voltage utilized is about 2.5 volts, as properly as the charging present is about 25 mA (from ambient inside light)

Finally, here’s a schematic on the electric hook-up. The circuitry for charging batteries is unregulated, and is dependent about the operator to disconnect the battery prior to it obtains overcharged. The circuitry for that NiCads can be an specifically crude regulator, however it keeps the batteries from over-charging. Here, two sequence silicon rectifiers restrict the voltage to about 1.3- 1.4 Volts (1.43 Volts is about perfect for any NiCad to terminate charge), A prepared advancement would be to include genuine regulators to be sure that over-charging cannot occur. A 14 Volt fixed-voltage-regulator can be perfect for that lead-acid battery, and perhaps some thing just a little a great deal more superior for that NiCads.
