This Arduino based battery discharge monitor aims to provide an estimation of the capacity left in the battery by measuring and plotting its discharges. This Arduino based battery discharge monitor ...
[Trent M. Wyatt]’s CPUVolt library provides a fast way to measure voltage using no external components, and no I/O pin. It only applies to certain microcontrollers, but he provides example Arduino ...
Trying to figure out the capacity left in a battery based on only its voltage is difficult. The equivalent-series-resistance (ESR) of the battery makes the cell’s voltage a function of the current ...
