Hi All
Has anyone had any experience of using a Picaxe to create a Coulomb counter. I have created a circuit to measure the Voltage of a Li-ion battery with a range 24-29V, however its not very accurate.
I read a thread once and I think is was here about someone who had created a circuit to count the current that had been used from a battery and then produce a battery gauge by subtracting the current counted from the "known" capacity of the battery to give a more accurate battery level compared to just a simple voltage reading.
If someone has experience or remembers that thread (I cant find it now!) or has any ideas which would help, as always I'd be very grateful for any help.
Thanks
