Battery level indicator indicates battery status only by bright LEDs. For example, six LEDs are bright means that 60% battery capacity remains. This article explains how to design the battery level indicator. You can use this circuit to check the car battery or the inverter. So by using this circuit, we can increase the battery life.
This circuit is designed based on lm3914 IC (integrated chip). This IC is LED Spot / Bar Display Driver.
Battery level indicator Circuit principle:
The heart of this battery level indicator circuit is LM3914 IC. This IC takes analog input voltage and conducts 10 LEDs linearly according to analog input voltage. In this circuit there is no need for resistors in series with led because the current is regulated by the IC.
This circuit is designed based on lm3914 IC (integrated chip). This IC is LED Spot / Bar Display Driver.
