Maxim Integrated has developed an algorithm to accurately estimate the battery state of charge and safely handle most batteries. Designers of lithium-ion (Li-ion) battery-powered devices such as wearables, electric bicycles, power tools and internet of things (IoT) products can improve the end-user experience by extending run-time and delivering accurate battery state-of-charge (SOC) data with the MAX1726x ...

Battery Fuel Gauge with Zero Parts and Zero Pins on AVR

It can be nice to know how much battery power you have. It becomes critically important with LiPo batteries since you can permanently damage them by running the voltage down too low. Typically battery voltage detection requires adding a circuit with extra parts and their associated power requirements. Wouldn’t it be great to be able to do this using nothing but software? Read on for a no parts, no pins, no ...
