In the 6V solar battery charger circuit, the LM317 is set up to generate a fixed 7V output using the resistances 120 ohms and 560 ohms. The voltage comparators in the LM324 quad op-amp are used to compare the voltage levels during the charging or discharging process of the battery.
Here is a solar charger circuit that is used to charge Lead Acid or Ni-Cd batteries using the solar energy power. The circuit harvests solar energy to charge a 6 volt 4.5 Ah rechargeable battery for various applications. The charger has voltage and current regulation and over voltage cut-off facilities.
So, let’s dive into the world of renewable energy and learn how to create a solar battery charger! To build the solar battery charger, you must first connect the LM317 voltage regulator IC and the BC547 transistor with the help of resistors and capacitors. Then, connect the LED indicators and the voltage comparators using the LM324 quad op-amp.
This must be precisely set such that the emitter produces not more than 1.8V with a DC input of above 3V. The DC input source is a solar panel which may be capable of producing an excess of 3V during optimal sunlight, and allow the charger to charge the battery with a maximum of 1.8V output.
Solar charger with current regulation and cut off. VR is placed between the adjust pin and ground to provide an output voltage of 9 volts to the battery. Resistor R3 Restrict the charging current and diode D2 prevents discharge of current from the battery. Transistor T1 and Zener diode ZD act as a cut off switch when the battery is full.
If a solar panel that is characterized for 12V is applied with a 6V battery, the maximum current must be reduced to about 0.7A: e.g. battery voltage = 6V, solar panel voltage = 18V. P = (18V – 6V) * 0.7A = 9.6W. In this case, the solar panel power may not exceed 10W. When charging, the heat sink normally runs warm.
