12 Volt Battery Level Indicator Circuit Diagram

By | July 30, 2022



On any given day, a person might be out camping, taking part in some outdoor activity, cruising around on their ATV, or otherwise using a 12 volt battery power source. In any of these cases, it's important to keep track of the battery's level of charge, so that you can make sure you don't deplete it completely and end up stranded. Enter the 12 Volt Battery Level Indicator Circuit Diagram.

This simple and low-cost circuit is a great way to easily monitor your battery level, giving you the information you need at a glance. The schematic diagram is versatile and can be adapted to different scenarios, since it can be used with lead acid batteries of any size, from small 12V batteries all the way up to large 24V batteries.

The circuit works by using two comparators, one for each voltage range (low and high). The comparator for the low-voltage range is connected to the battery via a Voltage Divider Circuit, and the comparator for the high-voltage range is connected to the power supply. When either of the comparators detects a voltage below or above its setpoint, it will activate the LED associated with that voltage range. When the LED is lit, it indicates that the battery is in the respective low or high voltage range.

Another benefit of this circuit is that it can be powered directly by the battery being monitored, making it very efficient and low-cost. As long as the battery is charged, the circuit will work properly, and no extra power sources are necessary.

Overall, the 12 Volt Battery Level Indicator Circuit Diagram is a simple yet effective way to monitor the charge of a 12V or 24V battery. It's easy to setup and use, and provides a visual indication of the battery's charge level. Having this information is essential to make sure you don't deplete the battery completely, leaving you stranded in the dark.
