But the start and stop voltages will be set according to the battery’s voltage. The same procedure is done for other batteries. The circuit is tuned now you can connect the power supply back and remove the adjustable power supply. make sure you make the perfectly crimped RJ45 connector: Trim the outer sheath back about. Now to set the start voltage of charging change the voltage of the adjustable power supply to 5.9V. Download, install and run Driver Booster on Windows 11 or 10. Now replace the power supply in this circuit with the adjustable power supply and do not connect any battery with the circuit. Since the voltage of a fully charged 6V battery s 7.3V on a DMM so set 7.3V on the adjustable power supply. For that, you will need an adjustable power supply and follow these steps. Circuit TuningĪ simple tuning needs to be done to charge the battery automatically. Obsolete, Circuits Electronic component search and free download site. In this way, it will switch ON the whole charger circuit from the mains when the battery needs to be charged and switches off when the battery is charged fully. LM324 Pinout, Equivalent, Applications, Features WebMay 14. You can connect the relay to the main plug of the power supply. The LED4 will indicate that the battery is getting charged. When the battery’s charging is full LED1 will glow. They are used to set start and stop voltages for the charging process of the battery. Both are connected with variable resistors VR1 and VR2. These two op-amps are working as a comparator to detect the voltage of the battery. We are using an operational amplifier IC LM358 that has two built-in op-amps.
