Lastly, supply 13v and above, and all LEDs would glow.īattery Level Indicator Circuit using LM3914 When you supply 5v, two LEDs would glow, give 10v, and 3 LEDs would light up. Also, the third, fourth, fifth LEDs show 60%, 80%, and 100%, respectively.Īlso, different voltages will make the LEDs glow. The first LED shows 20%, while the second shows 60%. This indicator circuit displays the battery percentage via the LEDs in ascending order. Once you give above 13v, all the LEDs on the circuit should light up. These wires are for the DC power supply.įinally, make sure your circuit matches the diagram and supply some power to the circuit. Next, take your input wires, brown (positive terminal) and black wire (negative), and solder them to the PCB. Ensure you connect the LEDs in series.Īfter connecting all your components, solder the wires of the LED and the resistors as in the image below: Using the circuit diagram above, insert all your LEDs and resistors into the PCB. Here are the steps you’ll need to follow for this circuit:

Here are the materials you need for this circuit:.

Here’s the circuit diagram below:īattery Voltage Indicator Circuit Diagram

What’s more, the circuit is not expensive to build. This circuit is easy to show the current percentage of any battery.

How to Make a Battery Charge Indicator Circuit? This integration is capable of delivering a more accurate indication of the battery charge state. Other electronic devices like power banks and smartwatches also have battery charge indicator lights that tell you when your battery is low or full.įurthermore, a smart battery system features a controller that’s integrated with an interchangeable battery pack. Also, you can see the amount of time and battery power you have left when your laptop is not charging.Īdditionally, phones and computers aren’t the only devices with a battery charge indicator.

Likewise, a battery charge display shows the battery in charge mode in portable computers that use rechargeable batteries. Others indicate battery charge level through percentages. Some mobile phone battery charge indicators are usually in bar graphs -which means the more bars you see, the better the battery charge status.

Examples of such technology are mobile phones and computers. Plus, battery indicators usually have a visual indication that accurately displays the battery’s state of charge.Īlso, different technologies that require an ideal battery to operate always have an inbuilt battery indicator.

īattery indicators are devices that show the status of a battery. So, in this article, you’ll learn everything about battery charge indicators and how to make an easy battery charge indicator circuit. Luckily, there is a way to prevent overcharging from damaging your batteries: battery charge indicators. Additionally, the casting of the battery could become too hot and cause flammable hydrogen to build up inside the sealed battery cells, leading to a bad battery. It could also be damaging to users if not controlled. Overcharging is terrible for your battery health as it can cause batteries to melt or swell.
