In portable electronics designs, typical battery-monitoring systems measure battery voltage and battery current to detect when the battery needs charging or replacement. In this post, I’ll demonstrate battery-voltage and current-monitoring circuitry for cost-optimized systems using operational amplifiers (op amps).
The battery monitoring circuit finds its applications in many devices. Mobile phones, tablets, and laptops have a battery monitoring circuit that shows the battery of the gadget. Chargeable battery banks for charging mobile phones or tablets also use battery monitoring circuits for their recharging.
The proposed battery voltage status monitor circuit using 4 LEDs makes use of comparators in the form of opamps from the IC LM324. This IC is much versatile than the other opamp counterparts due to its higher voltage tolerance level and due to the quad opamps in one package.
A: Monitoring battery voltage is crucial for battery-powered projects because it allows you to keep track of the battery’s state of charge. By monitoring the voltage, you can determine when the battery is running low and needs to be recharged or replaced. This helps prevent unexpected shutdowns and ensures the reliability of your project.
