Circuit Schematic Automatic Battery Charger using 723-IC and SCR

BatteryCharger. - Here is electronic Circuit Schematic Automatic Battery Charger using 723-IC and SCR like in Figure 1 below. In this circuit schematic the basic component used are 723-IC and SCR. 

In here we will give you global description about Circuit Schematic Automatic Battery Charger using 723-IC and SCR and then we will give you link to continue your reading from original source as external website.

Circuit Schematic

Component Part

  1. 723 IC
  2. SCR
  3. Resistors
  4. Capacitors
  5. Optocoupler
  6. LED
Description

Circuit schematic like in Figure 1 above is Circuit Schematic Automatic Battery Charger using 723-IC and SCR. Eleccircuit site describe that this is how to modify old Lead-acid battery charger or convert power supply to automatic battery charger form. To protect battery over charging.
We use simple circuit with comparator circuit by CA723 regulator and power SCR cut off current controller.

The working principle

As Figure 1 is circuit diagram of this project. The charging and stop charging of this circuit will check voltage drop across the battery. If voltage across less than 13.8 volts. The circuit will begin charging, but voltage across rises to 14.4 volts. The circuit will stop automatically.

When battery is fully charged. The circuit will stop since voltage across the battery too high. That is ?he voltage across the battery Are equal to the input voltage. The voltage comparator circuit internal IC1 will acts to stop the Q1. The adjustment voltage regular of IC1 will get voltage through the diode-D1 which is applied current about 10 mA.

Then the reference voltage divider circuit inside IC1 will get to dividing the voltage down to 2.2 volts. by R1 and R2. Which this reference voltage will be compared with the battery voltage that is adjusted from VR1.
