I am designing a circuit which will contain a rechargeable battery. The circuit will be a microcontroller based one. The microcontroller has an ADC input which I'm going to use for monitoring battery voltage level.
I need a data/look-up table, or a graph, or a mathematical relationship between battery voltage level and
state of charge of the battery.
I haven't decided what battery type to use, but probably it will be a Ni-Mh or Li-Ion battery.
Is there any information you can share with me?
