Any time battery voltage falls under a particular value LED1 ceases to glow and the buzzer begins sounding indicating that the battery is discharged and requires recharging. And it begins charging the battery as soon as the main power is available. The output gets regulated at 15Vįor charging the connected 12 volt rechargeable battery at the output of the voltage regulator. This DC voltage is then delivered to the voltage regulator IC 7815. The main 230V or 110V input could be the first steped down through a step-down transformer, after that it may be rectified and filtered. The charging circuit is created around voltage regulator IC 7815 and a couple of BC transistors 547 BJTs. How the simple battery charger circuit works This circuit design undoubtedly aids for your daily life battery charging purposes. The benefit of this indicator is that a buzzer notifies you once the battery has to be recharged.
This design additionally includes a twin indication system in the form of a battery charging indicator, and a low battery buzzer indicator.
