Simple Solar Battery Charger Circuit Diagram

Simple solar radio battery charger.

Simple solar battery charger circuit diagram. The charging current passes to lm317 voltage regulator through the diode d1. A solar cell radio used a 3v or two 1 2v nickel cadmium battery or nickel metal hydride battery in it. Solar battery charger circuit principle. These solar cells should be able to charge one 1 2 volt battery or two 1 2 volt batteries in series at a rate of 20 ma for 200 mah battery 30 ma for a 300 mah battery or 60 ma for a 600 mah battery.

The charging circuit for these batteries is simple a solar cell connected to a diode then connected to a nicad battery. This circuit is designed to provide charging current upto 3 amps and this circuit don t have reverse polarity protection or over. This design additionally includes a twin indication system in the form of a battery. Solar battery charger operated on the principle that the charge control circuit will produce the constant voltage.

You can use this circuit to charge 12v sla battery or 12v gel cell battery and so on. It is quite difficult to find such a voltage charger. I have added in the brown wire as brown line the diode as a blue line i have also added in the ve ve makers for the battery. Simple 12v battery charger with battery indicator.

The circuit uses a 0 14 volt 5 ampere step down transformer and a 10 amps bridge rectifier module to convert ac to dc. This is the simple solar solar radio battery charger circuit. Circuit diagram of solar panel battery charger step 6 from below you can see the soldered connections how they run along the copper tracks. The transistor is the only active component which is positioned as a switch for preventing the battery voltage from reaching the connected leds during day time.

It gives 12 volt and 5 amps current for quick charging of the battery. The output voltage and current are regulated by adjusting the adjust pin of lm317 voltage regulator. It uses a mini jack socket for charging. This is a simple 12v battery charger circuit with indicator circuit is a smart charger circuit.

If the battery is partially discharged full charge will be attained in one hour. This is the circuit of a simple 12 volt battery charger for lead acid battery. As can be seen in the given circuit diagram the design basically consists of a solar panel a pnp transistor few leds a battery and a few resistors. The battery can not be removed.

Simple 12 volt battery charger circuit diagram designed by using few easily available components and this circuit is suitable for different types of batteries needs 12 volt.
