Basic 12v car battery full charge status monitor circuit board.. Description. Nov 6, 2020 - How to make a simplest 12v battery full charge indicator circuit at home with simple diagram. 1. basically its a battery voltage detector cum indicator circuit. DZ1 = 5.1 volts lWzener. Battery full charge alarm circuit. With a 6 amp charger it may take ages for your battery to get charged, or simply the charging process might fail to initiate. Next, gradually increase the DC voltage input and watch the LEDs glow. First, connect the 12v battery to the circuit's input and adjust the POT RV1 until D1 starts emitting light. For example, a 12V battery fully charged will show 12.6V, and when it's 50% used it will show 12.1V on a multimeter. The transformer T1 steps down the input 230V/50HZ AC supply to a 6V AC. When you reach 12v, all 10 LEDs will light. The working of this circuit is explained below. Read more. The circuit uses just a couple of transistors as the main active components. For example, if out of 10 six LEDs are glowing it means 60 percent of the battery power is left. circuit is very simple 12v zener diode is used with reverse polarity and will not allow to pass any voltage when voltage is under 12v and when voltage crosses the 12v and reaches to 13v zener diode. The simple 12V battery status indicator is a circuit that shows the battery state only by flashing LEDs. By : "AMKP40 technology" (YouTube). At this rate the battery will take around 10 to 12 hours for getting fully charged. Battery charging indicator circuit.
