Hi all,
I have a project which needs to take 12VDC from a Battery however I cannot take it offline to charge it. I also have a 13.8VDC PWM Power Supply @ 15A.
I need
1. A Circuit that can take 13.8VDC from the power supply available to trickle charge the battery properly as it should be without monitoring or timers. (For example I do not wish to base the charging on a timer such that I assume that the battery needs 4 hours to charge... instead I would like the charger to be intelligent)
2. I need to know how much charge the battery has on it.. maybe if its too hard to know during charging, at least I need to know for sure when there is no power connected.
3. I need to use the battery while it is being charged.
I also don't mind if I have to buy some specialised IC to make this easier as long as you can help me build a circuit with it
Thanks so much for your help.
PS: Even if you don't know how to answer one of these questions, still reply because anything helps at the moment
I know I could use a computer UPS but these are more complex since they actually convert AC to DC and back to AC and from 230VAC to 13.8VDC and back to 230VAC and in my case this is totally unnecessary... not to mention that I would need to convert it back to 12VDC or do major modifications for the UPS. Also a UPS with all its problems won't give me feedback on how much the battery has left.
