Enhanced Battery monitoring module
Need to design a system that will sense and allow monitoring of four variables
(a) Charge level of two Lead acid batteries, (b) presence of AC mains (c) Availability of Sunlight and
provide the output in the form of :
1) % remaining charge of the two batteries (LED output & logic level output)
2) indication of battery charging/discharging status (LED output & logic level output)
3) On /Off status for variables (b) & (c), and an 'ENABLE' output dependent on a logical function of
all the variables being sensed.
* Battery capacity 4Ah to 300 Ah
* Minimal current drain for this monitoring circuit
We can discuss the reference design to be used
