Circuit Diagram
Circuit Operation
The solar-based battery charger works on the rule that the charge control circuit will create a constant voltage. The charging current goes to the LM317T voltage regulator through the diode D1. The yield voltage and current controls by adjusting the adjusted pin of the LM317T voltage controller. The battery during the charging state utilizes the same current.
The schematic shown here is a very efficient automatic solar-power-based battery charger circuit. Which utilizes to charge 12V SLA batteries from solar-based cells. The circuit is utilizing an LM317T voltage controller IC. The BC548 transistor is filling in as a switch that will separate the ground of the LM317T from the solar-powered cell when the battery becomes fully charged.
Applications and Uses
- The solar oriented charger circuit that is utilizing to charge Lead Acid or Ni-Cd batteries utilizing the solar-based vitality power.
- The circuit harvests solar oriented vitality to charge a 6volt 4.5 Ah rechargeable battery for different applications. The charger has a voltage and current regulator and over-voltage cut-off facilities.
